  Synthesis, characterization, and biological assessment of the four stereoisomers of the H3 receptor antagonist 5-fluoro-2-methyl-N-[2-methyl-4-(2-methyl[1,3′]bipyrrolidinyl-1′-yl)phenyl]benzamide

  摘要：

  This Letter describes the asymmetric synthesis of the four stereoisomers (8a-8d) of a potent and highly selective histamine H-3 receptor (H3R) antagonist, 5-fluoro-2-methyl-N-[2-methyl-4-(2methyl[1,3']bipyrrolidinyl-1'-yl)phenyl]benzamide (1). The physico-chemical properties, in vitro H3R affinities and ADME of 8a-8d were determined. Stereoisomer 8c (2S, 3'S) displayed superior in vitro H3R affinity over other three stereoisomers and was selected for further profiling in in vivo PK and drug safety. Compound 8c exhibited excellent PK properties with high exposure, desired brain to plasma ratio and reasonable brain half life. However, all stereoisomers showed similar unwanted hERG affinities.
