on as chelating agents in cosmetics. Pentasodium Pentetate is readily soluble in water, but the corresponding free acid is not. Pentasodium Pentetate is used in almost 400 cosmetic products over a wide range of product categories, although it is mostly used in hair dyes and colors at use concentrations of 0.1% to 1.0%. Pentetic Acid and Pentasodium Pentetate inactivate metallic ions, such as calcium and magnesium, to maintain stability and appearance of cosmetic products. The inactivation of other metallic ions such as iron or copper also helps to prevent the oxidative deterioration of cosmetics and personal care products.

Oxandrolone is a synthetic, orally active anabolic-androgenic steroid. Oxandrolones interact with androgen receptors in target tissues. Oxandrin is indicated as adjunctive therapy to promote weight gain after weight loss following extensive surgery, chronic infections, or severe trauma, and in some patients who without definite pathophysiologic reasons fail to gain or to maintain normal weight, to offset the protein catabolism associated with prolonged administration of corticosteroids, and for the relief of the bone pain frequently accompanying osteoporosis. Side effects include: elevated aminotransferases (ALT, AST), lipid abnormalities (e.g., decreased HDL cholesterol concentrations). Cardiovascular side effects have included edema, with and without congestive heart failure. Oxandrolone may inhibit the metabolism of oral hypoglycemic agents. In patients with edema, concomitant administration with adrenal cortical steroids or ACTH may increase the edema.

Idoxuridine is an antiviral agent use in keratitis caused by herpes simplex virus. As a prescription drug it comes as a 0.1% ophthalmic solution/drops (Herplex and Dendrid). The first studies of the compound for treatment of human herpes simplex started in early 1960s. Being a structural analog of thymidine idoxuridine inhibits viral DNA replication by substituting thymidine. The effect of idoxuridine results in the inability of the virus to reproduce and/or infect tissues. Idoxuridine also blocks viral thymidine kinase as its substrate analog.

Phytic acid is a major phosphorus storage compound of most seeds and cereal grains. It has the strong ability to chelate multivalent metal ions, especially zinc, calcium, and iron. Phytic acid is also considered to be a natural antioxidant and is suggested to have potential functions of reducing lipid peroxidation and as a preservative in foods. Clathrin-associated adaprot complex AP-2 has it been suggested may act as one of the receptor sites for Phytic acid. Both in vivo and in vitro experiments have demonstrated striking anticancer (preventive as well as therapeutic) effects of Phytic acid.

Clemizole is a drug in clinical development for the treatment of hepatitis C virus (HCV) infection. Clemizole is a novel inhibitor of TRPC5 channels. Clemizole is an H1 antagonist. Clemizole, an antihistamine drug that was once widely used for treatment of allergic disease, was recently discovered to be a potent inhibitor (IC50, 24 nM) of the interaction between an HCV protein (NS4B) and HCV RNA. Although clemizole was widely used during the 1950s and 1960s, this was before contemporary regulatory requirements were established for new drug development, and there is very minimal information about its pharmacokinetics and metabolism.

Nandrolone, also known as 19-nortestosterone or 19-norandrostenolone, is a semisynthetic anabolic-androgenic steroid derived from testosterone. Nandrolone is used in the form of a variety of long-acting prodrug esters for intramuscular injection, the most common of which are nandrolone decanoate. Nandrolone decanoate is indicated for the management of the anemia of renal insufficiency and has been shown to increase hemoglobin and red cell mass. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis. Anabolic steroids have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. Synthetic version of nandrolone was developed in 1950. But nandrolone for sale appeared later only in 1962 in the form of decanoate under the trade name Deca-Durabolin (Organon company).

Troleandomycin (also known Triacetyl-oleandomycin and having brand name Tao) is a macrolide antibiotic which used to for the treat of infections of the upper and lower respiratory tract: such as tonsillitis, bronchitis, sinusitis, and pneumonia. However, the brand name Tao was discontinued. Troleandomycin acts by penetrating the bacterial cell membrane and reversibly binding to the 50 S subunit of bacterial ribosomes or near the "P" or donor site so that binding of tRNA (transfer RNA) to the donor site is blocked. Translocation of peptides from the "A" or acceptor site to the "P" or donor site is prevented, and subsequent protein synthesis is inhibited.

Pyrvinium (Viprynium) is an anthelmintic effective for pinworms. Pyrvinium is used in the treatment of enterobiasis caused by Enterobius vermicularis (pinworm). Pyrvinium has being shown to be a potent inhibitor of Wnt signaling (EC(50) of ∼10 nM). Pyrvinium binds all casein kinase 1 (CK1) family members in vitro at low nanomolar concentrations and pyrvinium selectively potentiates casein kinase 1α (CK1α) kinase activity. Pyrvinium pamoate (PP) is a potent noncompetitive inhibitor of the androgen receptor (AR). A noncompetitive AR inhibitor pyrvinium has significant potential to treat CRPC, including cancers driven by ligand-independent AR signaling.

Digoxin is a cardiac glycoside derived from the purple foxglove flower. In 1785, the English chemist, botanist, and physician Sir William Withering published his findings that Digitalis purpurea could be used to treat cardiac dropsy (congestive heart failure; CHF). Digoxin has been in use for many years, but was not approved by the FDA for treatment of heart failure (HF) until the late 1990s. Another FDA indication for digoxin is atrial fibrillation (AF). Digoxin also has numerous off-label uses, such as in fetal tachycardia, supra-ventricular tachycardia, cor pulmonale, and pulmonary hypertension. Digitoxin inhibits the Na-K-ATPase membrane pump, resulting in an increase in intracellular sodium and calcium concentrations. Increased intracellular concentrations of calcium may promote activation of contractile proteins (e.g., actin, myosin). Digoxin also has Para sympathomimetic properties. By increasing vagal tone in the sinoatrial and atrioventricular (AV) nodes, it slows the heart rate and AV nodal conduction.
