Lecozotan hydrochloride Chemical Properties, Uses, Production
Description
Lecozotan HCl (SRA-333) is a potent and selective 5-HT antagonist that significantly enhances KCl-stimulated glutamate and acetylcholine release from the hippocampal dentate gyrus and has cognitive enhancing properties. Chronic administration of Lecozotan HCl did not induce 5-HT(1A) receptor tolerance or desensitization in a behavioral model demonstrating 5-HT(1A) receptor function.
Uses
Treatment of cognitive deficits associated with Alzheimer’s disease (5-HT1A receptor antagonist).
IC 50
5-HT1A Receptor: 4.5 nM (Ki)
