Ganglefene is a coronary vasodilator. This n-cholinoblocker was originally studied for its effects on coronary circulation in angina pectoris. Animal studies have also shown shortened recovery period of motor functions after ganglefene administration. One rodent study showed that modulation of the n-cholinergic system by ganglefene in the developing fetal brain leads to changes in the quantitative and qualitative characteristics of elements of sexual behavior in pubescent offspring.

Emopamil is a phenylalkylamine calcium antagonist. Emopamil has optically active stereoisomers. Emopamil enhanced the postischemic restoration of high-energy phosphate levels. The racemic mixture and the (-)-enantiomer of emopamil caused similar metabolic changes while (+)-enantiomer of emopamil proved to be ineffective. Emopamil is able to reverse multi-drug resistance in human KB cell lines. No differences in reversing potency were observed between emopamil (R)-isomers, (L)-isomers and the racemic form. There is a pharmacological relationship between sigma1-binding site and the mammalian sterol C8-C7 isomerase which is identical with the emopamil binding protein.

Clofeverine is a compound synthesized by the Japanese company Fujisawa Pharmaceutical. Clofeverine is a highly selective relaxant for gastrointestinal smooth muscles with a beta-receptor stimulative nature. On isolated ileum, the inhibitory effect of clofeverine for spontaneous motility was comparable to that of isoproterenol and 100 times higher than that of papaverine.
