Pyrrolidine Analogues of Lobelane: Relationship of Affinity for the Dihydrotetrabenazine Binding Site with Function of the Vesicular Monoamine Transporter 2 (VMAT2)
摘要:
Ring size reduction of the central piperidine ring of lobelane yielded pyrrolidine analogues that showed marked inconsistencies in their ability to bind to the dihydrotetrabenazine (DTBZ) binding site on the vesicular mono-amine transporter-2 (VMAT2) and their ability to inhibit VMAT2 function. The structure-activity relationships indicate that structural modification within the pyrrolidine series resulted in analogues that interact with two different sites, i.e., the DTBZ binding site and all alternative site on VMAT2 to inhibit transporter function.

A novel approach to chiral 2,5-disubstitutedpyrrolidines, starting from chiral 2-phenyl-glycinol, 1,5-dimethoxytetrahydrofuran, and benzotriazole, involves the diastereoselective substitution by Grignard reagents of a benzotriazolyl group in a crystalline intermediate obtained in high yield.
