4-Chloro-DL-phenylalanine is a selective and irreversible inhibitor of tryptophan hydroxylase, a rate-limiting enzyme in the biosynthesis of serotonin (5-HYDROXYTRYPTAMINE). 4-Chloro-DL-phenylalanine acts pharmacologically to deplete endogenous levels of serotonin.
Eflornithine(Difluoromethylornithine) inhibits polyamine biosynthesis by the selective, irreversible inhibition of ornithine decarboxylase (ODC). A chemoprotective agent that blocks angiogenesis. Its biological half-life is 8 hours.
Hydroquinone is a Melanin Synthesis Inhibitor. The physiologic effect of hydroquinone is by means of Depigmenting Activity. It also posesses antioxidant properties that can cause toxicity in several organs, notably the kidney.
Resorcinol is a chemical compound that serves as an antiseptic,an disinfectant, and a chemical intermediate for the production of many other pharmaceuticals.
Tyloxapol is a nonionic liquid polymer of the alkyl aryl polyether alcohol type, used as a surfactant to aid liquefaction, removal of mucopurulent and bronchopulmonary secretions. It also blocks plasma lipolytic activity, and thus the breakdown of triglyceride-rich lipoproteins.
Sulfabenzamide is an antibacterial/antimicrobial which also exhibit their antitumor effects through multiple mechanisms including inhibition of membrane bound carbonic anhydrases, prevention of microtubule assembly, cell cycle arrest, and inhibition of angiogenesis.
Piperazine, GABA receptor agonist, is an anthelmintic used in the treatment of the intestinal nematodes Ascaris lumbricoides and Enterobius vermicularis.
Hexylresorcinol is an organic compound with local anaesthetic, antiseptic and anthelmintic properties, is a potent inhibitor of mushroom tyrosinase. The IC50 values of hexylresorcinol for monophenolase is 1.24 μM and for diphenolase is 0.85 μM.
