Amiperone is a neuroleptic drug. It prolonged the latency (T) and reduced the frequency (F) of the noise escape response rate in rats. It also inhibited lever-press response and reduced the shock-avoidance rate at very low dose levels in rats.

Amikhellin (AK), an antimitotic drug, is a synthetic water-soluble derivative of khellin, an alkaloid extracted from seeds of Ammi Visnaga. Amikhellin has been used so far mostly as a vasodiator.

Alphameprodine (ACSCN 9604) is an opioid analgesic classified by the United States Drug Enforcement Administration under Schedule I of illegal substances. The stereoisomer betameprodine is similarly classified, however alphameprodine is more widely used (both are referred to as Meprodine). Alphameprodine is a structural analogue of meperidine. It exerts physiological effects characteristic of opioids, such as analgesia, euphoria and sedation, as well as itching, nausea, and respiratory depression.
