Hormone Disruptors – The Biggest Hormone Disruptors

Hormones are messengers that signal to our body’s glands and organs, regulating core functions like growth and development, reproduction, sex drive, metabolism, sleep and stress. But certain chemicals called endocrine disruptors throw off the delicate balance of our hormone system.

Fortunately, there are steps we can take to minimize exposure. Start with ditching plastic water bottles, buying organic strawberries and eating fresh, unprocessed foods.

1. Bisphenol A (BPA)

Bisphenol A (BPA) is one of the highest volume chemicals produced worldwide, used primarily as a starting material and plasticizer in polycarbonate production. Approximately 90% of Americans have BPA metabolites in their urine, and BPA is found in the blood of nearly all people over the age of 6.

Endocrine disruptors mimic hormones and can interfere with their normal actions. They are usually more harmful at higher levels of exposure, and their effects can differ depending on the stage of life when they are exposed.

BPA binds to estrogen receptors, and alters cellular responses to hormones, including induction of insulin resistance, adiposogenesis, and pancreatic beta-cell dysfunction. It also up-regulates HOXB9, which is associated with chemoresistance in cancer. These changes can have serious consequences for patients on chemotherapy.

2. Phthalates

Phthalates are a huge class of chemicals used in the manufacturing of plastic (most commonly a type of plastic called polyvinyl chloride or vinyl). They are added to plastic products as plasticizers to make them flexible.

In laboratory studies, phthalates have been linked to lowered testosterone levels and reproductive organ changes in males. The chemicals are also suspected endocrine disruptors, which interfere with the biosynthesis, secretion, action or metabolism of naturally occurring hormones.

Like BPA, phthalates affect key hormones involved in reproduction and development. They can alter hormone receptors and interfere with intracellular signaling pathways, among other things. You are exposed to phthalates when you pull back your shower curtain, put on your perfume and apply nail polish. They are also in the food you eat and the air you breathe.

3. Toluene

A volatile petrochemical solvent and paint thinner, toluene is found in a variety of products used in construction, cosmetics and fuel production. It is also a known carcinogen and a suspected neurotoxin. It has been linked to developmental defects in children born to mothers who have exposed themselves to toluene vapors during pregnancy.

Toluene has been shown to decrease ovarian cell viability and inhibit proliferation, apoptosis and secretion of LH and FSH in cultured granulosa cells. It has also been shown to reduce clastogenic activity when administered with benzene in the presence of sister chromatid exchanges (Dobrokhotov, 1972; Dobrokhotov & Enikeev, 1977). When toluene is released into the environment it generally enters water and soil from spills, or leaks from leaking underground storage tanks. It then evaporates rapidly and is converted to other chemicals in the air (benzaldehyde and cresol).

4. Formaldehyde

Formaldehyde is a chemical used in many manufacturing and household products including wood furniture, carpets, and some manufactured housing materials. It is also produced endogenously in the human body and is found in food and medicine.

Several animal studies have shown that exposure to formaldehyde during pregnancy and early childhood can lead to adverse reproductive outcomes, including menstrual abnormalities, infertility, and spontaneous abortions. However, the results from these studies vary widely depending on the study design, route of exposure and duration of exposure, as well as confounding factors.

UNC Gillings School of Global Public Health researchers have conducted the first-ever analysis of DNA damage from low doses of inhaled formaldehyde, using ultrasensitive liquid chromatography-tandem mass spectrometry. They found that even long-term occupational exposure to formaldehyde — at concentrations that may be encountered in a workplace setting — did not cause detectable levels of exogenous DNA damage or increase the number of DNA monoadducts or DNA-protein crosslinks in rats.

5. Dioxin

The body relies on hormones to control development, metabolism and reproduction. Any chemical that mimics or interferes with those hormones can cause problems, including reproductive issues like changes in fertility and pregnancy loss, as well as a host of other health concerns.

Dioxins are widespread and are the unintentional byproducts of industrial processes such as the manufacture of polyvinyl chloride (PVC) products, the bleaching of paper with chlorine, and incinerating organic waste. They have a very long half-life in the environment, and they tend to accumulate in soil because they resist dilution by rainwater and can be taken up by fat tissue. Once they enter the human body, they are difficult to break down and are stored in fat cells, where they remain for a very long time.

Endocrine Disruptors Examples

The human body’s endocrine system depends on hormones to perform many vital functions. But some chemicals mimic, block or interfere with the production and action of these hormones.

These man-made chemicals can be found in everyday products such as plastic bottles, metal food cans, cosmetics, detergents and flame retardants. They are known as endocrine disruptors and examples include BPA, DDT, PCBs, and Triclosan.

BPA

Bisphenol A (BPA) is a chemical that mimics the hormone estrogen, and interferes with the body’s delicate endocrine system. It has been linked to reproductive and developmental problems, and it may also contribute to a variety of health conditions.

It is particularly dangerous for pregnant women, infants, and children, because it can disrupt normal hormone function during critical periods of development. BPA has been linked to a variety of problems, including obesity, infertility, and low birth weight. It has also been linked to behavioral problems, such as hyperactivity and attention deficit disorder.

Several studies have shown that BPA can alter the expression of genes involved in the endocrine system. It can also trigger cellular growth and tumor formation, which could lead to a poor prognosis for cancer patients. It can also inhibit the effectiveness of chemotherapy in some cancer cells. This is because it upregulates the expression of ERRg, a gene that promotes breast and ovarian cancer cell proliferation.

DDT

The endocrine system sends messages that regulate everything from growth and reproduction to hunger and body temperature. An endocrine disruptor can interfere with these delicately tuned signals, even at low doses. Many pharmaceutical drugs, including antibiotics like triclosan and diethylstilbestrol, industrial chemicals such as polychlorinated biphenyls and bisphenol A, and pesticides like DDT act as endocrine disruptors.

DDT is a potent insecticide that affects the nervous and reproductive systems of aquatic organisms. Its neurotoxic effects include repetitive discharge of the abdominal nerve cord and convulsions in animals, as well as inhibition of calcium influx into nerve terminals and delayed sodium channel inactivation in neurons.

In humans, DDT and its metabolites (including DDE) have been associated with breast cancer in epidemiological studies. Its toxicity to the fetus and its endocrine disruption effects on birds were highlighted in Rachel Carson’s 1962 book, Silent Spring. DDT and its metabolites also bind weakly to the androgen receptor in the prostate, while binding more strongly to estrogen receptors.

PCBs

Polychlorinated biphenyls (PCBs), like DDT, PFAS and some flame retardants, are extremely persistent, toxic and bioaccumulative chemicals that are known to have adverse effects on the nervous, immune and reproductive systems at low doses. They can mimic natural hormones, block their action or alter the breakdown or synthesis of hormones in the body. These chemicals are found in food, air and personal products and they can persist in the environment for decades, accumulating in fatty fish, breast milk and house dust.

PCBs are known to affect the hypothalamus-pituitary-gonadal axis and have been linked with decreased sperm motility, lower fecundity and earlier menarche in females. They are also known to interfere with thyroid hormone function and to cause cognitive-behavioral disorders. A new study shows that prenatal and early postnatal exposure to a commercial mixture of PCBs, Aroclor 1254, delays radial neuronal migration in the developing cortex in rats and leads to altered cognitive functions. The findings were presented Thursday at ENDO 2023, the Endocrine Society’s annual meeting in Chicago.

Triclosan

Triclosan is an antimicrobial chemical that is added to many household and industrial products to prevent bacterial contamination. It is highly effective in reducing the growth of bacteria and fungi, but it also has been shown to have adverse effects on human health. These effects include increased risk of allergies, decreased fertility, and disruptions in thyroid function.

The chemical can be absorbed through the skin and enters the bloodstream. It is also found in urine and breast milk. It is particularly concerning for women and people assigned female at birth because it can cross the placenta and enter a woman’s body, where it can interfere with hormones.

In a study conducted in mice, triclosan caused a decrease in serum thyroid hormone levels and a delay in the onset of puberty. The same effect was observed in a study of prenatal triclosan exposure and anatomical measurements in Danish infants. The authors suggest that the results may indicate that triclosan has endocrine disrupting properties.

The Fundamentals of Chemistry

Chemistry is a fascinating and complicated science. In chemistry classes, students learn about the fundamentals of this science and its many applications in our daily lives.

The Article format is up to 5000 words, including Introduction and Discussion sections (some overlap with the Abstract is allowed). It may include Minireviews, Research Articles, Scientific Perspectives or Viewpoint articles.

Molecular Weight

The molecular weight (MW) of a compound is the total mass of all the atoms in that compound. This is calculated by identifying the compound, finding its chemical formula (for example, water has a chemical formula of H2O), and then finding the atomic weights of each element in the compound. Each atomic weight is then multiplied by the number of atoms of that element in the compound (i.e., the number of hydrogen atoms in water is 6 and the number of carbon atoms in hexane is 14).

The molecular weight is then added together to get the compound’s molar mass. The molecular weight is usually expressed in unified atomic mass units (u) and can be converted to grams per mole using the molecular weight conversion factor or molar mass calculator. It can also be used to convert from molar mass to kilograms and back again. The molecular weight is also sometimes called the “formula weight,” which is the equivalent of the molar mass.

Atomic Weight

Atoms are so small that their weight cannot be measured directly. However, their mass can be measured relative to that of an atom of hydrogen. Dalton used experimental results to prepare the first Table of Atomic Weights. Early atomic weights were compared to the mass of oxygen-16, but after three isotopes of oxygen were discovered, it was decided in 1961 that carbon-12 would be the standard atom. An atom’s weight is now given in unified atomic masses, which are equal to one-twelfth the mass of an atom of carbon-12.

A “standard atomic weight” is the expected value that a chemist might expect to find in most naturally occurring samples of an element. Because the isotopic composition of natural terrestrial material varies, tabulated values are sometimes indicated with an interval. For example, Xe (xenon) has a characteristic terrestrial isotopic composition that prevents it from being a true single-atomic-weight element. Instead, its atomic weight is quoted as a range of two numbers, Xe(a), and Xe(b). The last significant figure in these tabulated values is only accurate to +-2 for all but twelve of the elements.

Atomic Number

The atomic number of an element is the number of protons in its nucleus. An equal number of protons and electrons gives an atom a neutral charge. These electrons occupy orbits around the nucleus. The outermost orbits are available to form chemical bonds with other atoms.

In the periodic table, each element has an atomic number that is unique. This number is indicated by a symbol above the element’s name. The symbol is often shortened to an abbreviation of the element’s name, such as H for hydrogen or Cl for chlorine. A number may also be added to the symbol, which indicates a specific isotope.

For example, tungsten (W) is a steel-gray colored metal with the atomic number of 74 in the periodic table. It is a transition metal and can be found in many compounds including tungsten carbide, tungsten oxide, and tungsten filaments used in lamps. The name tungsten is derived from the Swedish word for “heavy stone.” The mineral scheelite, which is the source of the chemical, was found to interfere with the smelting of tin.

Reactivity

‘Reactivity’ is a term used to describe the tendency of chemical substances to undergo chemical reactions. The reactivity of an element can be predicted by its position on the periodic table and in groups or families of elements. The metals in the lower left corner of the periodic table react rapidly with water and other substances.

Reactivities are based on the propensity of electrons in an atom to interact with orbitals of other atoms to form chemical bonds. This is rationalised at the atomic level using older valence bond theory and atomic orbital theories, but also more accurately at the quantum level by the Schrodinger equation and molecular orbital theory.

In addition to its use in washing soda and water, the compound molybdenum is a valuable industrial ingredient in high-temperature furnaces and for arc welding electrodes. Chronic exposure to molybdenum compounds may cause pulmonary fibrosis.

What Are Common Endocrine Disruptors?

The human population is daily exposed to a wide range of EDCs that can interfere with endocrine functions. Many of these chemicals are associated with the development of breast, testicular and ovarian cancers as well as metabolic diseases such as obesity.

Molecularly, EDCs share structural similarities to natural hormones and interact with nuclear steroid receptors. Common examples include polychlorinated biphenyls (PCBs), dioxins, phthalates and diethylstilbestrol (DES).

1. Pesticides

Endocrine disruptors are chemicals that interfere with the hormone system in humans and cause a wide variety of health problems, such as attention deficit hyperactivity disorder (ADHD), Parkinson’s and Alzheimer’s diseases, obesity, metabolic disorders including diabetes, cardiovascular disease, cancer and immune system impacts. They can mimic the actions of natural hormones, block or prevent their action by blocking the hormone receptors in cells or by altering synthesis, transport, metabolism and excretion.

Many endocrine disruptors are bio-persistent, meaning that they do not break down quickly in the environment. In one study, we measured metabolites of organophosphate, pyrethroid and phenoxy herbicides in urine from 619 reproductive-age women using liquid chromatography-tandem mass spectrometry. We found that higher levels of these metabolites were associated with an increased likelihood of endometriosis diagnosis.

2. Polychlorinated Biphenyls (PCBs)

EDCs include natural and human-made chemicals that mimic, block or interfere with the body’s hormones. They often bind to hormone receptors and cause the normal signaling process to be overstimulated. They can also bind to the enzymes that make or break down hormones, such as estrogens or androgens.

Studies of cell cultures, laboratory animals and wildlife have documented the effects of EDCs. It has been more difficult to demonstrate EDC impacts on humans, but there is evidence that they exist.

PCBs contaminate soil and water, and because of their chemical inertness and high lipid solubility, they bioaccumulate in the fat tissue of top food chain consumers (i.e. predatory fish, large mammals, humans). They have been shown to disrupt thyroid and reproductive function in men and women.

3. Triclosan

Triclosan is an antimicrobial chemical added to many household and industrial products to prevent bacterial and fungal growth. It is absorbed through the skin and can be ingested. It is also a moderate skin sensitizer and has been shown to interfere with thyroid hormone production.

Animal studies show that triclosan can reduce thyroid hormone levels. It is also of concern because it crosses the placenta and enters breast milk. It has been detected in human plasma, urine and fish tissues at low doses.

NTP scientists use a broad range of laboratory tests to evaluate chemicals for their potential to disrupt the hormone system. NTP also has been collaborating with other federal agencies, such as the Environmental Protection Agency (EPA), to develop integrated high-throughput testing strategies for screening chemicals for their ability to interact with hormones.

4. Bisphenol A (BPA)

Bisphenol A (BPA) is an endocrine disruptor that mimics or partly mimics naturally occurring hormones like estrogens and androgens in the body. It also binds to hormone receptors and blocks their normal function.

BPA is a chemical used to make certain hard plastics and epoxy resins that line metal cans and some baby bottles. It can leach into food when heated. It’s found in some polycarbonate water bottles and infant bottles marked with the recycling code “7.” It’s also found in some plastic food containers, napkins, and cash register receipts.

Studies show that low doses of this chemical can cause health effects in animals and humans. NIEHS and the National Toxicology Program are assessing BPA and other EDCs, including pesticides, perfluorinated chemicals, compounds that could replace BPA in the market, and flame retardants.

5. Flame Retardants

The body’s endocrine system produces hormones that regulate a wide variety of functions like metabolism, growth, development and reproduction. Chemicals that interfere with this system are called endocrine disruptors.

The vast majority of the endocrine disruptors scientists have tested are flame retardants. When chemists like Arlene Blum first showed that toddlers had 15 times higher levels of one type of flame retardant, brominated tris, in their urine than their mothers, regulators banned it from baby pajamas. But manufacturers simply switched to similar chemicals that scientists hadn’t evaluated yet.

These chemicals are added to furniture foam, electronics and building insulation to meet flammability standards set by government regulations. They can be mixed into the base material (additive flame retardants) or chemically bonded to it (reactive flame retardants). Some have been linked to cancer, hormone disruption and adverse developmental, behavioural, neurological and immune effects in humans and wildlife.

The Definition of Cheminformatics

Cheminformatics, also known as chemoinformatics, combines chemistry and computer science to organize and analyze chemical information. Its techniques allow chemists to perform a wide range of tasks, from identifying new chemicals to drug design.

Cheminformatics tools can filter large libraries of compounds for their ability to bind to specific targets, allowing researchers to focus on the most promising molecules. They can also create predictive models to identify important physicochemical properties that influence formulation.

Definition

Cheminformatics specialists use information technology to develop unified systems that organize and analyze chemical data. They may focus on molecular modeling, chemical structure coding and searching, or chemical information visualization. These systems enable chemists to make better use of existing scientific data and to predict unknown properties, such as spectral or toxicological characteristics. Cheminformaticians also have developed standardized methods for representing three-dimensional molecular structures and enabling searches for compounds with specific features.

In addition, chemoinformatics has made significant contributions in the drug discovery process, where large combinatorial libraries of chemical compounds are screened for drugs with particular therapeutic effects. These strategies rely on a range of cheminformatics techniques, including virtual library generation, structure-based synthesis design and high throughput screening. They also depend on chemoinformatics tools for analyzing structural similarity, predictive pharmacokinetics and ADMET profiling. These are all critical steps in developing new drug treatments. Chemoinformatics is a growing field that has benefited from the rapid advances in computer technology over recent decades.

Scope

The field of cheminformatics (also known as chemoinformatics, chemical informatics, or chemistry information science) is concerned with the collection, storage, analysis, and manipulation of chemical data. This data typically includes small molecule formulas, structures, properties, and spectra as well as the results of their biological or industrial activities.

The goal of the field is to apply information technology to chemical data and to assist in the development of new compounds, materials, and processes. Cheminformataticians work with massive amounts of data and construct information systems to organize, store, and analyze this data.

They develop standardized representations for two-dimensional and three-dimensional chemical structure data and use these to create databases that can be searched, analyzed, and visualized. They also design and develop software to implement and support these information systems. They have a deep understanding of the principles of chemistry and advanced knowledge of computer programming techniques, including graph theory and statistical analysis. This is an exciting and rapidly developing field with applications in numerous areas, most notably in drug discovery.

Methods

Cheminformatics relies on computational methods to process, analyze and interpret chemical information. It also applies computational techniques like machine learning to chemistry-related problems such as molecular docking and property prediction.

ML-based predictive models and algorithms can be used to identify compounds with high activity potential, prioritizing them for experimental testing and reducing the overall time and cost of drug discovery. This includes predicting drug-like properties such as solubility and toxicity, and identifying regions of the chemical space likely to yield active molecules.

Cheminformatics facilitates streamlined drug discovery processes by enabling rapid virtual screening of large library collections for the identification of novel therapeutic interventions. It also enables systematic exploration of structure-activity relationships (SAR) trends, which can guide the design and optimization of compound libraries. Furthermore, it can be employed in the design and selection of formulation components for drug compounds to enhance drug solubility and delivery and optimize therapeutic efficacy.

Applications

The field of cheminformatics, also called chemoinformatics or chemical informatics, is a powerful and essential discipline that unlocks the potential of molecules. It combines chemistry with the fields of computer science and data analysis, and it plays an important role in drug discovery, materials research, and many other scientific endeavors.

Cheminformatics techniques allow chemists to work with the vast amounts of chemical and biochemical information that is becoming available. By integrating this information, the discipline allows scientists to extract insights and make decisions more quickly and effectively.

Specifically, the discipline helps with identifying targets and screening compounds against them; drug discovery high-throughput screening (HTS) data mining; and prediction of ADMET properties such as absorption, distribution, metabolism, excretion, and toxicology (ADMET). In addition, it is often used to generate virtual libraries of chemicals that are not limited to those that can be purchased or synthesized, which is an especially valuable tool in following up on HTS hits.
