AMI-193

Uses

AMI-193 is a selective 5-HT2A and D2DR receptor antagonist. Endoplasmic reticulum (ER) stress inducer; Also, it is derived from 4-Fluorophenol (F595325), which is a fluorinated phenolic compound with various applications as an starting reagent for the synthesis of pharmaceutical goods.

Definition

ChEBI: An azaspiro compound that consists of 1,3,8-triazaspiro[4.5]decan-4-one having a phenyl group attached to N-1 and a 3-(4-fluorophenoxy)propyl attached to N-8. Selective 5-HT antagonist, which binds to 5-HT2 sites as potently as spipero e but has lower affinity for 5-HT2C receptors. Also a high affinity D2 receptor antagonist (Ki = 3 nM). Lacks the disruptive effect of spiperone on animal behaviour.

Biological Activity
