Sinomenine or cocculine is an alkaloid found in the root of the climbing plant Sinomenium acutum which is native to Japan and China. The plant is traditionally used in herbal medicine in these countries for rheumatism and arthritis. However, analgesic action against other types of pain seems to be limited. Sinomenine is a morphinan derivative that is related to the common cough suppressant dextromethorphan. The drug's anti-rheumatic effects are thought to be primarily mediated via release of histamine, but other effects such as inhibition of prostaglandin, leukotriene and nitric oxide synthesi

Zenazocine (INN; WIN-42,964) is an opioid analgesic of the benzomorphan family which made it to phase II clinical trials before development was ultimately halted and it was never marketed. It acts as a partial agonist of the μ- and δ-opioid receptors, with less intrinsic activity at the former receptor and more at the latter receptor (hence, it behaves more antagonistically at the former and more agonistically at the latter), and produces antinociceptive effects in animal studies.

Oxabolone is a synthetic anabolic-androgenic steroid (AAS) of the nandrolone (19-nortestosterone) group which was never marketed. It can be formulated as the cipionate ester prodrug oxabolone cipionate, which, in contrast, has been marketed for medical use.
