m3AChRs. The potency in displacement of [3H]-N-methylscopolamine from both m3- and m4AChRs generally increased with increasing chainlengths of the omega-aminoalkyl congeners. The amides of 7-aminoheptanoic acid and 8-aminooctanoic acid, and their Boc-protected derivatives, had comparable affinities to UH 5 (Ki = 5.0 and 4.5 microM at m3AChRs and at m4AChRs, respectively) at both receptors but lacked
