Its use was banned in the European Union in 2004, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could not show that this could be prevented nor that these levels were safe. At least two significant Canadian farm well studies showed that atrazine was the most common contaminant found. , atrazine was the most commonly detected pesticide contaminating drinking water in the U.S. Studies suggest it is an endocrine disruptor, an agent that can alter the natural hormonal system. However, in 2006 the U.S. Environmental Protection Agency (EPA) had stated that under the Food Quality Protection Act "the risks associated with the pesticide residues pose a reasonable certainty of no harm", and in 2007, the EPA said that atrazine does not adversely affect amphibian sexual development and that no additional testing was warranted. EPAs 2009 review concluded that "the agencys scientific bases for its regulation of atrazine are robust and ensure prevention of exposure levels that could lead to reproductive effects in humans". However, in their 2016 Refined Ecological Risk Assessment for It, it was stated that "it is difficult to make definitive conclusions about the impact of atrazine at a given concentration but multiple studies have reported effects to various endpoints at environmentally-relevant concentrations." EPA started a registration review in 2013. The EPA's review has been criticized, and the safety of atrazine remains controversial. EPA has however stated that "If at any time EPA determines there are urgent human or environmental risks from atrazine exposure that require prompt attention, we will take appropriate regulatory action, regardless of the status of the registration review process."

It, also known as Se-methylselenocysteine, is an analog of S-methylcysteine in which the sulfur atom is replaced with a selenium atom. It is an inhibitor of DMBA-induced mammary tumors and a "chemopreventive agent that blocks cell cycle progression and proliferation of premalignant mammary lesions and induces apoptosis of cancer cell lines in culture." Apoptosis has been proposed as the most plausible mechanism for the chemopreventive activities of selenocompounds. Se-It was more efficient at inducing apoptosis than selenite, but was less toxic. The "selenite-induced cell death could be derived from necrosis rather than apoptosis, since selenite did not significantly induce several apoptotic phenomena, including the activation of caspase-3." In the Nutritional Prevention of Cancer Trial, selenized yeast resulted in "a reduction in the incidence of prostate cancer and in total cancer incidence"; subsequent anticancer studies using selenomethionine did not show any benefit against cancer; but, selenized yeast contains both selenomethionine and methylselenocysteine. It is found in selenized yeast, and many vegetables: "As much as 80% of the total selenium" found in Allium species (onion, leek, garlic, ramps) Brassica species (broccoli, radish, Brussels sprouts, cabbage), and milk vetch (Astragalus species, Fabaceae) "is present as Se-methylselenocysteine." The bioavailability of selenium from Se-methylselenocysteine, "is likely to be similar to that from other organic selenium compounds." Specifically, "It is converted via the action of β-lyase, to methylselenol and then to hydrogen selenide, which is also the key metabolite derived from" all other common forms of selenium. But EFSA concluded that "given the absence of human studies on Se-methylselenocysteine, the relatively sparse database on the bioavailability of selenium from this source and the limited data on the safety of this source compared with other selenium compounds, the Upper Limit for selenium defined by the Scientific Committee on Food cannot be used for judging its safety."

It (Ybt) is a siderophore found in the pathogenic bacteria Yersinia pestis, Yersinia pseudotuberculosis, and Yersinia enterocolitica, as well as several strains of enterobacteria including enteropathogenic Escherichia coli and Salmonella enterica. Siderophores, compounds of low molecular mass with high affinities for ferric iron, are important virulence factors in pathogenic bacteria. Iron—an essential element for life used for such cellular processes as respiration and DNA replication—is extensively chelated by host proteins like lactoferrin and ferritin; thus, the pathogen produces molecules with an even higher affinity for Fe than these proteins in order to acquire sufficient iron for growth. As a part of such an iron-uptake system, yersiniabactin plays an important role in pathogenicity of Y. pestis, Y. pseudotuberculosis, and Y. entercolitica.

It is a prohormone of the major insect molting hormone 20-hydroxyecdysone, secreted from the prothoracic glands. It is of steroidal structure. Insect molting hormones (ecdysone and its homologues) are generally called ecdysteroids. Ecdysteroids act as moulting hormones of arthropods but also occur in other related phyla where they can play different roles. In Drosophila melanogaster, an increase in ecdysone concentration induces the expression of genes coding for proteins that the larva requires. It causes chromosome puffs (sites of high expression) to form in polytene chromosomes. Recent findings in the laboratory of Chris Q. Doe have found a novel role of this hormone in regulating temporal gene transitions within neural stem cells of the fruit fly. It and other ecdysteroids also appear in many plants mostly as a protection agent (toxins or antifeedants) against herbivorous insects. These phytoecdysteroids have been reputed to have medicinal value. They are part of herbal adaptogenic remedies like Cordyceps, yet an ecdysteroid precursor in plants has been shown to have cytotoxic properties as well as antioxidant properties on lipid peroxidation. Tebufenozide, sold under the Bayer trademark MIMIC, has ecdysteroid activity although its chemical structure has little resemblance to the ecdysteroids.

It (, ; brand name and development code MER/29, as well as many other brand names) was the first synthetic cholesterol-lowering drug. It was patented in 1959 and introduced in the United States in 1960. The developmental code name of triparanol, MER/29, became so well known that it became the registered trade name of the drug. It was withdrawn in 1962 due to severe adverse effects such as nausea and vomiting, vision loss due to irreversible cataracts, alopecia, skin disorders (e.g., dryness, itching, peeling, and "fish-scale" texture), and accelerated atherosclerosis. It is now considered to be obsolete. The drug acts by inhibiting 24-dehydrocholesterol reductase, which catalyzes the final step of cholesterol biosynthesis, the conversion of desmosterol into cholesterol. Although effective in reducing cholesterol levels, this results in tissue accumulation of desmosterol, which in turn is responsible for the side effects of triparanol. Unlike statins, triparanol does not inhibit HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis, and in contrast to triparanol, statins can lower cholesterol levels without resulting in accumulation of intermediates like desmosterol. Estrogen is known to lower cholesterol levels, but produces side effects like gynecomastia and decreased libido in men. It was hoped that a drug could be developed that lacked overt estrogenic effects but still lowered cholesterol levels. It is a triphenylethanol and was derived from chlorotrianisene (TACE), a nonsteroidal triphenylethylene estrogen. The nonsteroidal triphenylethanol antiestrogen ethamoxytriphetol (MER-25) is a derivative of triparanol. The selective estrogen receptor modulator clomifene is also structurally related to triparanol. The developers of triparanol jokingly referred to it as a "non-estrogenic estrogen" due to its lipid-lowering effects without other estrogenic effects.

It (13-MTD) is a fatty acid known to induce apoptosis or “programmed cell death” of certain human cancer cells. 13-MTD was originally purified from a soy fermentation product and can be chemically synthesized; however, the synthesized form contains the same biological property of its natural form.

It is a natural product found in Arabidopsis thaliana, Homo sapiens, and other organisms with data available.

It is a dipyridodiazepine that is 5,11-dihydro-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepine which is substituted by methyl, oxo, and cyclopropyl groups at positions 4, 6, and 11, respectively. A non-nucleoside reverse transcriptase inhibitor with activity against HIV-1, it is used in combination with other antiretrovirals for the treatment of HIV infection. It has a role as an antiviral drug and a HIV-1 reverse transcriptase inhibitor. It is a dipyridodiazepine and a member of cyclopropanes.

It is a natural product found in Homo sapiens with data available.

It is n-Ethylpiperidine in which one of the hydrogens attached to the methyl group is substituted by a 4-butoxybenzoyl group. It has a role as a topical anaesthetic. It is a member of piperidines and an aromatic ketone.

It is a methylbenzene that is benzene in which five of the hydrogens are replaced by methyl groups.

It (Marsilid, Rivivol, Euphozid, Iprazid, Ipronid, Ipronin) is a non-selective, irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class. It is a xenobiotic that was originally designed to treat tuberculosis, but was later most prominently used as an antidepressant drug. However, it was withdrawn from the market because of its hepatotoxicity. The medical use of iproniazid was discontinued in most of the world in the 1960s, but remained in use in France until its discontinuation in 2015.

It is a homodetic bicyclic heptapeptide having a sulfide bridge.

It (previously marketed as Peganone) is an anticonvulsant drug used in the treatment of epilepsy. It is a hydantoin, similar to phenytoin. It is not available in the United States.

It, sold under the brand name Biaxin among others, is an antibiotic used to treat various bacterial infections. This includes strep throat, pneumonia, skin infections, H. pylori infection, and Lyme disease, among others. It can be taken by mouth as a tablet or liquid or can be infused intravenously.> Common side effects include nausea, vomiting, headaches, and diarrhea. Severe allergic reactions are rare. Liver problems have been reported. It may cause harm if taken during pregnancy. It is in the macrolide class and works by slowing down bacterial protein synthesis. It was developed in 1980 and approved for medical use in 1990. It is on the World Health Organization's List of Essential Medicines. It is available as a generic medication. It is made from erythromycin and is chemically known as 6-O-methylerythromycin.

It is a pregnane-based steroidal hormone produced by the outer-section (zona glomerulosa) of the adrenal cortex in the adrenal gland, and acts on the distal tubules and collecting ducts of the kidney to cause the conservation of sodium, secretion of potassium, increased water retention, and increased blood pressure. The overall effect of aldosterone is to increase reabsorption of ions and water in the kidney. It has a role as a human metabolite and a mouse metabolite. It is an 11beta-hydroxy steroid, a 21-hydroxy steroid, a 18-oxo steroid, a 20-oxo steroid, a C21-steroid hormone, a steroid aldehyde, a 3-oxo-Delta(4) steroid, a primary alpha-hydroxy ketone and a mineralocorticoid.
