Pericosine A is a fungal metabolite that has been found inP. byssoidesand has anticancer activity.1It inhibits the growth of a variety of cancer cells, including breast, colon, lung, ovary, stomach, and prostate cell lines (GI50s = 0.05-24.55 μM) and increases survival in a P388 mouse xenograft model when administered at a dose of 25 mg/kg. Pericosine A inhibits EGFR by 40 to 70% when used at a concentration of 100 μg/ml. It also reacts with organosulfur compounds in skunk spray to form stable thioethers as odorless products.2 1.Yamada, T., Iritani, M., Ohishi, H., et al.Pericosines, antitumour metabolites from the sea hare-derived fungus Periconia byssoides.

Clomesone is a synthetic non-steroidal drug that can be used as a molecular structural unit. It is a drug commonly used to treat female infertility and works by blocking the action of estrogen in the brain. It has been shown to be effective in inducing ovulation in women suffering from polycystic ovary syndrome and other infertility problems.

U92016A hydrochloride is a potent and orally acitive agonist of 5-HT1A receptor which is metabolically stable. U92016A hydrochloride has an exceptionally high degree of intrinsic activity that binds with high affinity to human 5-HT1A receptors expressed in Chinese hamster ovary cells with Ki value of 0.2 nM [1] [2].

Albizziin is amino acid analog which acts as a competitive inhibitor of asparagine synthetase with respect to glutamine. Albizziin has been used to isolate mutants of Chinese hamster ovary cells with alterations in levels of the target enzyme. Several classes of mutations can be distinguished on the basis of cross-resistance to beta-aspartyl hydroxamate, another amino acid analog. Studies on asparagine synthetase indicate that resistance to albizziin may be due to altered regulation of asparagine synthetase, structural mutations of the enzyme, and gene amplification.
