Imidazole is a planer five-member heterocyclic ring with 3C and 2N atom and in ring N is present in 1st and 3rd positions. The imidazole ring is a constituent of several important natural products, including purine, histamine, histidine and nucleic acid. Being a polar and ionisable aromatic compound, it improves pharmacokinetic characteristics of lead molecules and thus used as a remedy to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules. The imidazole derivatives possess extensive spectrum of biological activities such as antibacterial, anticancer, antitubercular, antifungal, analgesic, and anti-HIV activities. The organic compound is used in the chemical industry as an intermediate in the production of pharmaceuticals, pesticides, dye intermediates, auxiliaries for textile dyeing and finishing, photographic chemicals and corrosion inhibitors. The chemical possesses properties (corrosivity to skin, irreversible damage to eyes, teratogenic effects) indicating a hazard for human health. Humans are exposed by consumer products (chemical concentrations up to 10%) and at the workplace. Therefore, the chemical is a candidate for further work. An exposure assessment and if indicated a risk assessment is recommended.

3-Phenyl-1-propanol is a fragrance ingredient used in many compounds. It may be found in fragrances used in decorative cosmetics, fine fragrances, shampoos, toilet soaps and other toiletries as well as in non-cosmetic products such as household cleaners and detergents. It is a colorless slightly oily liquid, possessing a warm and mild, balsamic-floral, sweet odor of moderate tenacity. This material has been reported to occur in nature, with highest quantities observed in Guava and Feyoa. The worldwide volume of use for 3-phenyl-1-propanol is in the region of 100–1000 metric tons per year. 3-Phenyl-1-propanol was used to study the hydrogenation of trans-cinnamaldehyde using water-soluble organometallic complexes. It was used as starting reagent during the enantioselective synthesis of (S)- and (R)-dapoxetine.

Morantel (1,4,5,6-tetrahydro-1-methyl-2-[2-(3-methyl-2-thienyl)ethenyl pyrimidine) is a tetrahydro-pyrimidine anthelmintic, differing from the related analogue pyrantel by the presence of a methyl group on the thiophene ring. Morantel tartrate, manufactured by Pfizer, Inc., was approved in the United States for use in cattle in 1981, and entered the market in early 1982. Three formulations have been approved in the United States: RUMATEL® Medicated Premix-88; RUMATEL Cattle Wormer Bolus, and PARATECT FLEX™ Diffuser, a sustained release bolus. It is intended to treat roundworms and tapeworms. Morantel is administered in lactating and non lactating cattle as morantel tartrate as a slow-release bolus (11.8 g morantel base per animal) or as a single oral dose of 6 to 7.5 mg morantel base/kg bw and in pigs at a single dose equivalent to 7.5 mg base/kg bw. In sheep, the citrate salt is administered at a single dose equivalent to 5 to 6 mg morantel base/kg bw. Morantel acts as a potent agonist at the acetylcholine receptors on the muscle cells of nematodes. Activation of the acetylcholine receptors induces a prolonged, spastic paralysis of the worms and expulsion from the host. It also been reported to block neurotransmission in vertebrates, to possess nicotine-like properties and to mimic acetylcholine at receptors in autonomic ganglia, adrenal medullae and respiratory tissues. Morantel and its salts are not used in human medicines.

Benzophenone is the organic compound. It is a flavouring agent evaluated as safe at current levels of intake by joint FAO/WHO Expert Committee on Food Additives (JECFA) and approved by FDA as a food additive and as UV protector. Substituted benzophenones such as oxybenzone (benzophenone-3) and dioxybenzone are used in sunscreens in cosmetics and as a sunscreen ingredients in some topical drugs in combination with skin lighteners for gradual fading of dark (brownish) areas in the skin such as freckles, age and liver spots or treatment of melanosis. Benzophenone derivatives can be used as a photo initiators. Benzophenone used in practical synthesis of some drugs.

Maropitant (trade name Cerenia in the U.S. and other countries), used as maropitant citrate is a neurokinin (NK1) receptor antagonist, which was developed by Zoetis specifically for the treatment of motion sickness and vomiting in dogs. It was approved by the FDA in 2007 for use in dogs, and was later approved for use in cats. Maropitant also has anti-nociceptive (analgesic) properties. Maropitant inhibits binding of substance P to NK-1 receptors. Substance P is an emetogen experimentally, and is found endogenously, along with NK-1 receptors, in the emetic center, chemoreceptor trigger zone, and in vagal afferent nerves in the gastrointestinal tract.

Lactic Acid, L- (L-lactic acid, L-lactate) is the levorotatory isomer of lactic acid, the biologically active isoform in humans. Lactic acid or lactate is produced during fermentation from pyruvate by lactate dehydrogenase. Lactate dehydrogenase is isomer-specific so that production and metabolism of D-lactate require D-LDH and L-lactate requires L-LDH. Mammalian cells only contain L-LDH so that in humans the lactate produced is almost exclusively L-lactate. Carbohydrate-fermenting bacterial species (e.g. lactobacillus spp) have by contrast both enzymes and therefore the capacity to produce both D-lactate and L-lactate. L-lactic acid is the primary agonist of hydroxycarboxylic acid receptor 1 (HCA1), which is a Gi/o-coupled G protein-coupled receptor (GPCR). Poly-L-lactic acid is an absorbable, semi-permanent, injectable implant that can be used to restore volume and stimulate collagen formation gradually. It is FDA-approved for the correction of facial fat loss associated with antiretroviral therapy-induced lipoatrophy in HIV patients. It is FDA-approved for use in immunocompetent people for the correction of nasolabial fold deficiencies and other facial wrinkles. It has been used off-label to enhance the cheeks, hands, neck, thighs, gluteal enhancement and chest wall deformities, such as pectus excavatum or thoracic deformities secondary to surgical procedures.
