New Serotonin 5-HT1A Receptor Agonists with Neuroprotective Effect against Ischemic Cell Damage
摘要:
We report the synthesis of new compounds 4 35 based on structural modifications of different moieties of previously described lead UCM-2550. The new nonpiperazine derivatives, representing second-generation agonists, were assessed for binding affinity, selectivity, and functional activity at the 5-HT1A receptor (5-HT1AR). Computational beta(2)-based homology models of the ligand receptor complexes were used to explain the observed structure affinity relationships. Selected candidates were also evaluated for their potential in vitro and in vivo neuroprotective properties. Interestingly, compound 26 (2-{6-[(3,4:-dihydro-2H-chromen-2-ylmethyl)amino]hexyl}-tetrahydro-1H-pyrrolo[1,2-c]imidazole-1,3(2H)-dione) has been characterized as a high-affinity and potent 5-HT1AR agonist (K-i, = 5.9 nM, EC50 = 21.8 nM) and exhibits neuroprotective effect in neurotoxicity assays in primary cell cultures from rat hippocampus and in the MCAO model of focal cerebral ischemia in rats.
