Abstract :
Extensive structural modification of immepyr (+)-2 led to the discovery of trans-4-methyl-3-imidazoyl pyrrolidine (±)-3a as a potent and highly selective H3 agonist. The pyrroline (±)-3a was resolved, and its (+) enantiomer, Sch 50971 [(+)-3a], showed a greater separation of H3 and H1 activities in vivo (H3/H1 ratio 330) than (R)-α-methylhistamine (+)-1 (H3/H1 RATIO = 17), the standard H3 agonist.
