Jervine (11-Ketocyclopamine) is a naturally occuring steroidal alkaloid is derived from the Veratrum plant species. Jervine is a teratogen implicated in birth defects when consumed by animals during a certain period of their gestation. Over the Hedgehog signaling pathway Jervine effectively inhibit the tumor growth using three human tumor xenograft models including lung cancer, pancreatic cancer and basal cell carcinoma. Jervine has the potential to advance to a treatment for different tumors.

1,3-Dicyclohexylurea (DCU) is a potent endogenous inhibitor of soluble epoxide hydrolase (sEH), that has been found in human serum. Soluble epoxide hydrolase has been implicated in cardiovascular disease and inflammation in mammals. Endogenously produced 1,3-dicyclohexylurea may have physiological significance via regulation of soluble epoxide hydrolase activity in vivo.

p-Chlorobenzoic acid is a major metabolite of analgesic agent zomepirac sodium in rat (present as conjugates) and mouse and a minor one in monkey and man. It is a metabolite of antidepressant Lofepramine hydrochloride, and anxiolytic and a muscle relaxant Chlormezanone too. Sodium salt of p-Chlorobenzoic acid is used as a preservative. p-Chlorobenzoic acid may prove useful clinically to prevent and reverse the accumulation of toxic levels of acyl- and arylCoA esters. If the hepatic damage in Reye’s Syndrome is due to the dead-end formation of the CoA esters of acyl- and aryl-CoA esters, then p-chlorobenzoic acid may block their formation, thereby relieving the inhibitions of gluconeogenesis and urea synthesis and preventing some of the damage to the liver.
