Solasodine is an aglycone of solamargine and solasonine, which are the major solasodine glycosides present in numerous species of the solanaceae family including potato, tomato or garden egg plant etc. In Phase II clinical trial was shown that solasodine glycosides exhibit anticancer activity against skin cancer. The effects of aglycone solasodine on cancer cells have also been investigated. Solasodine inhibits the growth of human colon and liver cancer cell. In addition, solasodine effectively inhibits proliferation of HER2-overexpressing breast cancer cells and inhibits invasion of human lung cancer cells. Solasodine possesses CNS activities such as antipyretic, anticonvulsant and memory enhancing effects. Also, solasodine has been found to possess diuretic, antifungal, hepatoprotective, immunomodulatory, anti-spermatogenetic and antiandrogenic effects.

Vilaprisan, a small molecule progesterone receptor antagonist is being developed by Bayer HealthCare Pharmaceuticals (formerly Bayer Schering Pharma) for the treatment of endometriosis and uterine leiomyoma. Hormonal imbalance observed in women with endometriosis is a potential target for treating endometriosis. Vilaprisan is a highly selective steroidal progesterone receptor modulator (SPRM). It is a partial agonist of progesterone receptor, which means that the drug activates progesterone receptors to a certain degree upon binding. This triggers a cascade of biochemical reactions that result in the suppression of prostaglandin production. This, in turn, relieves symptoms such as pain and bleeding. Modulating progesterone by taking vilaprisan might help in treating endometriosis over the long term. Phase I and II studies give encouraging results on the efficacy of vilaprisan at different doses. Like other SPRMs, vilaprisan induces benign changes of endometrium (PR modulator-associated endometrial changes, PAECs). These disappear as treatment is discontinued. Unlike GnRHa treatment, neither UPA nor vilaprisan induce hypoestrogenism and associated symptoms. Phase III studies are ongoing to confirm efficacy and safety of vilaprisan in long-term treatment of symptomatic fibroids.

L-DEPRENYL-D2 C-11 is a selective irreversible inhibitor of monoamine oxidase B (Mao-B) which labels functionally active enzyme. It is used as a positron emission tomography radioligand for measurement of the Mao-B activity in vivo brain.

Mallinckrodt (previously Sucampo Pharmaceuticals) is developing nobiprostolan (RK 023), a topical therapy for male pattern baldness (androgenetic alopecia) and hypotrichosis. The drug is a physiologically active fatty acid derivative. Nobiprostolan is in Phase IIa clinical trials for the treatment of male pattern baldness.
