摘要

A new series of potent and selective histamine-3 receptor (H3R) antagonists was identified on the basis of an azaspiro [2.5] octane carboxamide scaffold. Many scaffold modifications were largely tolerated, resulting in nanomolar-potent compounds in the H3R functional assay. Exemplar compound 6s demonstrated a selective profile against a panel of 144 secondary pharmacological receptors, with activity at only σ2 (62% at 10 μM). Compound ...
