Butopiprine is alkoxyethyl α-phenyl-α-piperidinoacetate possessing spasmolytic, local anesthetic, and antitussive activity.

Propoxate (R7464) is a potent anesthetic agent in cold-blooded vertebrates, which has never been marked and has never been used on humans.

Propetamide (also known as FC 379) is a propionamide derivative patented by All-Union Scientific Research Chemical-Pharmaceutical Institute as an analgesic compound. In mice, Propetamide produced both a depression of spontaneous motility and relaxation of muscular tone. However, Propetamide was less active than meprobamate. Propetamide at 400 mg/kg reduced muscular relaxation in 70% of the animals, while the same effect was obtained in 100% of the animals with meprobamate at 200 mg/kg.

FENPIPALONE is an oxazolidinone derivative with central nervous system depressant and antiinflammatory activity in animal models. However, FENPIPALONE did not demonstrate any usefulness for severely ill chronic schizophrenic patients.

Vinconate possesses both encephalotropic and psychotropic properties. Animal experiments have shown that this compound could induce the facilitation of phosphatidylinositide (PI) turnover via the stimulation of muscarinic acetylcholine receptors. In addition, vinconate could lead to the direct activations of PIP2-specific and cytosolic phospholipase C. The drug was on the stage of preregistration for the treatment of cognition disorders in Japan. However, information about the further fate of this drug is not available.
