Publication Abstract from PubMed
Tropanylamide was investigated as a possible scaffold for beta-tryptase inhibitors with a basic benzylamine P1 group and a substituted thiophene P4 group. Comparing to piperidinylamide, the tropanylamide scaffold is much more rigid, which presents less opportunity for the inhibitor to bind with off-target proteins, such as cytochrome P450, SSAO, and hERG potassium channel. The proposed binding mode was further confirmed by an in-house X-ray structure through co-crystallization.
