Gibberellic acid was first discovered in Japan in 1935 as a result of the study of a condition common in rice plants called "foolish seedling" disease, which caused the plants to grow much taller than normal. The effects of gibberellins weren't widely understood until years later. Gibberellic acid, GA3 is a naturally occurring plant hormone that regulates the growth of plants, including triggering seed germination. Gibberellic Acid is not manufactured; it's a natural product extracted from the Gibberella fujikuroi fungus. There are over 100 known forms of gibberellic acid; GA3 is the most effective. Gibberellic acid (GA3) is used extensively in Egypt and other countries, to increase the growth of many fruits (such as strawberries and grapes) and vegetables (such as tomatoes, cabbages and cauliflower). Carcinogenic effect of Gibberellic acid has being demonstrated in several studies. Gibberellic acid increased the activity of testicular 3β-HSD and 17β-HSD and elevated testosterone content in rats, acting as an agonist of steroidogenesis in male rats. Gibberellic acid has being suggested to promote ulcer-healing, healing of surgical wounds or open fractures and treatment of bronchitis or thrombophlebitis in animals including humans.

Erucic acid is a monounsaturated omega-9 fatty acid found mainly in the Brassica family of plants such as canola, rapeseed, wallflower seed, mustard seed as well as Brussels spouts and broccoli. Erucic acid has many of the same uses as mineral oils but with the advantage that it is more readily biodegradable. Its high tolerance to temperature makes it suitable for transmission oil. Its ability to polymerize and dry means it can be - and is - used as a binder for oil paints. Increased levels of eicosenoic acid (20:ln9) and erucic acid (22:1n9) have been found in the red blood cell membranes of autistic subjects with developmental regression. While studies done on laboratory animals in the early 1970s show that erucic acid appears to have toxic effects on the heart at high enough doses, an association between the consumption of rapeseed oil and increased myocardial lipidosis, or heart disease, has not been established for humans. While there are reports of toxicity from long-term use of Lorenzo's oil (which contains erucic acid and other ingredients), there are no reports of harm to people from dietary consumption of erucic acid. In 2003, Food Standards Australia set a provisional tolerable daily intake (PTDI) for an average adult of about 500 mg/day of erucic acid, extrapolated based on "the level that is associated with increased myocardial lipidosis in nursing pigs."

Zomepirac Sodium (Zomax) is a pyrrole-acetic acid structurally related to tolmetin sodium. Zomepirac is a prostaglandin synthetase inhibitor and is not an opioid, an opioid antagonist, or a salicylate. Zomepirac was approved by the Food and Drug Administration for marketing in the United States as an analgesic. It was indicated for all forms of mild to moderately severe pain, and was being promoted as a "comprehensive, non-addicting analgesic." Later Zomepirac was found to be associated with fatal and near-fatal anaphylactoid reactions. The manufacturer voluntarily removed Zomax tablets from the Canadian, US, and UK markets in March 1983.

L-threonine is an essential amino acid. Threonine is a precursor of glycine. The biochemical studies on rats proved that glycine is synthesized from threonine (through threonine dehydrogenase pathway). Threonine dehydrogenase is the key enzyme in mammals like pigs, cat, and rats for degradation of 80% threonine. In adult humans, degradation of 7–11% of threonine is done by threonine dehydrogenase. The human L-threonine 3-dehydrogenase gene (GeneID: 157739, UniProtKB: Q8IZJ6 (TDH_HUMAN)) is an expressed pseudogene having lost the splice acceptor site preceding exon 6 and codon arginine-214 (CGA) is mutated to a stop codon (TGA). A few trials demonstrated that oral L-threonine may alleviate clinical signs of amyotrophic lateral sclerosis and spasticity in humans. L-Threonine has recently been brought into agricultural industry for balancing the livestock feed.

Leucine is an α-amino acid used in the biosynthesis of proteins. Leucine is an essential hydrophobic amino acid. It is used in the Leucine may be used some people as a supplement to build muscle. Leucine is also found in fish, meat, and poultry. In the pharmaceutical industry, L-leucine is used for parenteral and enteral nutrition and feeding, and is also used as a flavoring product and tablet lubricant in manufacturing. Leucine is an mTOR activator. It is a dietary amino acid with the capacity to directly stimulate muscle protein synthesis. As a dietary supplement, leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins in aged rats. Long-term leucine supplementation does not increase muscle mass or strength in healthy elderly men. Leucine potently activates the mammalian target of rapamycin kinase that regulates cell growth. Infusion of leucine into the rat brain has been shown to decrease food intake and body weight via activation of the mTOR pathway.

Histidine is an essential amino acid. L-histidine is converted to histamine by histidine decarboxylase, a pyridoxal 5'-phosphate-dependent enzyme. The copper(II)–l-histidine (1:2 complex at physiological pH) has been widely used in the treatment of Menkes disease (a genetic neurodegenerative disorder that leads to early death in the children due to impaired copper metabolism) and more recent use has been reported in the treatment of infantile hypertrophic cardioencephalomyopathy (a condition caused by mutations in SCO2, a cytochrome c oxidase assembly gene). CUSTODIOL HTK (Histidine-tryptophan-ketoglutarate) Solution is indicated for perfusion and flushing of donor kidneys, liver, and heart prior to removal from the donor or immediately after removal from the donor.

Kanamycin A is aminoglycoside anti-bacterial agent. Active against many strains of Gram-negative bacteria and Gram-positive Staphylococcus aureus and epidermis. Some strains of Mycobacterium bacterium are sensitive. Most active in alkaline solution. It binds to bacterial ribosomes and reduces mRNA translation hence reduces protein biosynthesis. However, it also exhibits some toxic effects towards mammalian cells.
