Lead(II) acetate is a white crystalline chemical compound with a sweetish taste. Lead(II) acetate is used as a mordant in textile printing and dyeing, as a drier in paints and varnishes, and in preparing other lead compounds. It was historically used as a sweetener and for cosmetics.

Silver iodide is an inorganic compound with the formula AgI. It is used as a photosensitive agent in photography, as a local antiseptic, as a chemical intermediate, and in cloud seeding for rain-making. The major hazards encountered in the use and handling of silver iodide stem from its toxicologic properties. Effects from exposure may include skin rashes, conjunctivitis, argyria (a permanent ashen-gray discoloration of skin, conjunctiva, and internal organs), headache, fever, hypersensitivity, laryngitis, and bronchitis.

Zuretinol (QLT091001, 9-cis-retinol) is a retinoid. Retinoids (vitamin A and its analogs) are essential dietary substances that are needed by mammals for reproduction, normal embryogenesis, growth, vision, and maintaining normal cellular differentiation and the integrity of the immune system. Within cells, retinoids regulate gene transcription acting through ligand-dependent transcription factors, the retinoic acid receptors (RARs), and the retinoid X receptors (RXRs). All-trans-retinoic acid binds only to RARs with high affinity, whereas its 9-cis isomer binds with high affinity to both RARs and RXRs. The actions of all-trans- and 9-cis-retinoic acid in regulating cellular responses are distinct and not interchangeable. Zuretinol is a retinal derivative for treatment of visual disorders. It is a synthetic retinoid replacement for 11-cis-retinal. It is an investigational product under development for the treatment of retinal diseases caused by gene mutations that interfere with the availability of 11-cis-retinal. The therapeutic strategy with Zuretinol is to facilitate recovery or restoration of visual function by acting as a replacement for missing 11-cis-retinal and restoring a key biochemical component of the visual (retinoid) cycle. Novelion Therapeutics is currently developing QLT091001 for the treatment of Inherited Retinal Disease caused by retinal pigment epithelium protein 65 (“RPE65”) and lecithin:retinol acyltransferase (“LRAT”) gene mutations, which include Leber Congenital Amaurosis (“LCA”) and Retinitis Pigmentosa (“RP”). QLT091001 has received orphan drug designations for the treatment of LCA (due to inherited mutations in the LRAT and RPE65 genes) and RP (all mutations) by the U.S. Food and Drug Administration (the “FDA”), and for the treatment of LCA and RP (all mutations) by the European Medicines Agency (the “EMA”).

Sodium acetate C-11 (C-11 acetate) Injection is a radiopharmaceutical commonly used for clinical studies with positron emission tomography (PET). It is used as a PET radiotracer for imaging cancer cells via incorporation into intracellular phosphatidylcholine membrane microdomains in cancer cells. Positron emission tomography using carbon-11 acetate (AC-PET) may help find local or distant metastases from prostate cancer. C-11 acetate is taken up in proportion to fatty acid synthesis. It is also taken up proportionally to myocardial blood flow, and therefore myocardial oxygen consumption. In rodents, there is clearance from all organs except the pancreas within one hour. Tumor uptake was clearly visible in 30 minutes. In humans, more than 80% of tracer is cleared from normal tissues within 20 minutes.It is taken up in cancer within the prostate and prostate cancer metastases, however, it has been reported that increased uptake can be seen in hyperplastic and benign prostate tissues. No urinary excretion is seen. No toxic effects have been demonstrated. The ongoing clinical trial NCT01530269 is studying how this imaging test may help influence the choice and extent of initial treatments, and subsequent treatments of prostate cancer.

Bornyl acetate is the main volatile constituent in numerous conifer oils and some Chinese traditional herbs, which has displayed an anti-inflammatory effect. In addition was shown, that this compound had therapeutic potentials for the osteoarthritis and may be developed as a preventive agent for lung inflammatory diseases. In combination with 5-fluorouracil, bornyl acetate possesses the anticancer activity by inducing apoptosis, DNA fragmentation as well as G2/M cell cycle arrest.

Prezatide is a tripeptide molecule consisiting of lysine, glycine and histidine, also known as GHK (glycyl-L-histidyl-L-lysine), that forms a complex with copper ions. Prezatide is used in cosmetic products (skin and hair) and is known help wound healing. Prezatide increases the synthesis and deposition of type I collagen and glycosaminoglycan. It is thought to play a role in the modulation of tissue remodeling by increases the expression of matrix metalloproteinase-2, as well as tissue inhibitor of matrix metalloproteinases-1 and -2. Prezatide has antioxidant activity due to its ability to supply copper for superoxide dismutase and anti-inflammatory ability due to the blockage the of iron (Fe2+) release during injury.

Melengestrol is a steroidal progestin and antineoplastic agent which was never marketed. An acylated derivative, melengestrol acetate, is used as a growth promoter in animals. Melengestrol acetate (MGA) is one of six steroidal hormone growth promoters approved for use in Canada and USA. These products are used to improve growth rate and feed efficiency, as well as to suppress estrus in beef heifers (CFIA 2008). They are not approved for use in any species other than beef cattle meant for slaughter. MGA is the only drug of its kind that is administered in animal feed, and its labelled dose in Canada is 0.4mg per heifer per day (CFIA 2008). A mandatory withdrawal of 2 days before slaughter is applied to any animal that is administered MGA.

Deslorelin is an GnRH agonist used in veterinary. It effects contraception by temporarily suppressing the reproductive endocrine system and preventing production of pituitary (FSH and LH) and gonadal hormones (estradiol and progesterone in females and testosterone in males). The observed effects are similar to those following ovariectomy or castration, but are reversed after the hormone content of the implant is depleted or the implant is removed. As an agonist, deslorelin first stimulates the reproductive system, which can result in estrus and ovulation in females or temporary enhancement of testosterone and semen production in males. Then, down-regulation follows the initial period of stimulation. Although deslorelin can also be an effective contraceptive in males of some species, manufacturer recommends its use primarily in females, since monitoring efficacy in females by suppression of estrous behavior or of gonadal steroids in feces is more straightforward than ensuring continued absence of sperm in males, since most institutions cannot perform regular semen collections. It can, however, be used to ameliorate aggression in males of some species, but higher dosages are usually needed. While the major application of deslorelin was initially male contraception, due to its two differing actions, either the stimulation of oestrus or the sterilization of fertility, its use has been increasing in the bitch as well. SUPRELORIN® F (deslorelin acetate) Implant is a once-yearly, subcutaneous implant that assists in the management of adrenal disease in ferrets.
