Tropirine is an antihistaminic, respiratory, anticholinergic agent.

Valtrate is a principle compound isolated from Valeriana jatamansi Jones, which is a Traditional Chinese Medicine used to treat various mood disorders. Valtrate at a high dose has been found to have sedative properties by inhibiting spontaneous motion and increasing the sleeping number induced by pentobarbital sodium in mice. In rats valtrate exhibits anxiolytic-like profiles in the elevated plus maze test and the open field test. Valtrate attenuated HPA axis activity by reducing the corticosterone level. Valtrate also possesses anti-breast cancer activities via cell cycle arrest, apoptosis, and inhibition of cell migration, thus supporting valtrate as a potential antitumor agent.

Truxipicurium, a derivative of alpha-truxillic acid, a curare-like drug, is a neuromuscular blocking agent with rigid structure.

Vinepidine, a derivative of vincristine participated in clinical trials as an antineoplastic agent. As a result, the extreme neuromuscular toxicity was observed, that is why this study was discontinued.

MK-0773 is an orally active selective androgen receptor modulator. The safety and efficacy of MK-0773 was evaluated in sarcopenic elderly women. The MK-0773- induced improvements in lean body mass were not accompanied by statistically significant improvements in physical function. Higher dose of MK-0773 or longer duration of therapy might have resulted in improvements in physical function, but liver transaminase elevations likely preclude further development of MK-0773. Drug-candidate had been in phase I clinical trials for the treatment of osteoporosis.

Oxiramide, an antiarrhythmic agent was studied as a cardiac depressant. However, information about the current use of this compound is not available.

Etarotene (Ro 15-1570) is an arotinoid sulfone. Etarotene inhibits RNase P, a ribonucleoprotein that endonucleolytically cleaves all tRNA precursors to produce the mature 5' end, thereby affecting tRNA biogenesis. Etarotene has antikeratinizing potential. It was undergoing phase III clinical trials with Roche in the US for the treatment of psoriasis and other skin.

Tocofenoxate is a semisynthetic tocopherol derivative. Vitamin E supplement.

Dioxethedrin is the ephedrine derivative. It is the beta-adrenergic agonist. As a bronchodilator and sympathomimetic agent is was used in antitussive syrup Bexol.

Menabitan is a synthetic cannabinoid exerting analgesic activity.
