Synthesis and biological characterization of pyridohomotropanes. Structure-activity relationships of conformationally restricted nicotinoids.


The recently discovered nicotinic agonist pyrido[3,4-b]norhomotropane [corrected] (PHT) as well as its N-methyl and 2'-methyl derivatives (syntheses reported herein) were compared with nicotine, nornicotine, and anatoxin a in a series of in vitro and in vivo assays. The results reveal that PHT possesses activity comparable to that of the highly potent… (More)
