Ingenol mebutate is a tetracyclic diterpenoid ester obtained by formal condensation of the carboxy group of (2Z)-2-methylbut-2-enoic (angelic) acid with the 3-hydroxy group of ingenol. Used for the topical treatment of actinic keratosis. It has a role as an antineoplastic agent. It is a carboxylic ester, a cyclic terpene ketone and a tetracyclic diterpenoid. It is functionally related to an angelic acid and an ingenol. Ingenol derivatives inhibit proliferation and induce apoptosis in breast cancer cell lines, formulating novel derivatives from Ingenol esters may be an innovative approach to develop new lead compounds to reactivate latent HIV. Ingenol mebutate is an effective treatment for actinic keratosis.

Cyclopamine is a Hedgehog (Hh) pathway antagonist with an IC50 of 46 nM in the Hh cell assay, it can increase levels of p27, and decreases both expression of IGF-II and activation of Akt in PC-3 prostate cancer cells. Cyclopamine as a novel, potent inhibitor of human breast cancer proliferation and estrogen responsiveness that could potentially be developed into a promising therapeutic agent for the treatment of breast cancer. Cyclopamine also can suppress the growth of leukemia and lymphoma cells. Cyclopamine is a member of piperidines. It has a role as a glioma-associated oncogene inhibitor.

5,3'-Dihydroxy-4',5'-dimethoxy-6,7-methylenedioxyisoflavone is an isoflavonoid.

Jervine exhibits cytotoxic activity against human tumor cell lines A549, PANC-1, SW1990 and NCI-H249, it induces COX-2 overexpression in human erythroleukemia cells. Jervine exhibits potent toxic effects against Colorado potato beetle.
