Etomidate (AMIDATE®) is an imidazole derivative anesthetic and hypnotic with little effect on blood gases, ventilation, or the cardiovascular system. It is intended for the induction of general anesthesia by intravenous injection. Etomidate (AMIDATE®) is also indicated for the supplementation of subpotent anesthetic agents, such as nitrous oxide in oxygen, during maintenance of anesthesia for short operative procedures such as dilation and curettage or cervical conization. It also produces a unique toxicity among anesthetic drugs - inhibition of adrenal steroid synthesis that far outlasts its hypnotic action and that may reduce survival of critically ill patients. The major molecular targets mediating anesthetic effects of etomidate (AMIDATE®) in the central nervous system are specific gamma-aminobutyric acid (GABA) type A receptor subtypes. The R(+) isomer of etomidate is 10 times more potent than its S(-) isomer at potentiating GABA-A receptor activity.

JTC 801 was developed by Japan Tobacco as a novel opioid receptor-like1 (ORL(1)) receptor antagonist. It was found, that JTC-801 completely antagonized the suppression of nociceptin on the forskolin-induced accumulation of cyclic AMP using ORL(1) receptor expressing HeLa cells in vitro. JTC 801 produced analgesic effects and was studied in phase II of a clinical trial for the treatment of neuropathic, cancer and postoperative pain. Nevertheless, that studies were discontinued.
