5-(Halomethyl)-2-pyranones as irreversible inhibitors of alpha-chymotrypsin.

A series of 5-(halomethyl)-2-pyranones were prepared and assayed as potential mechanism-based inhibitors of chymotrypsin, in order to test whether substitution of a suitable electron-withdrawing group at position 5 in a 2-pyranone can activate the ring for catalytic hydrolysis, as well as form a mechanism-based inhibitor. 3-Benzyl-5-(chloromethyl)-2… CONTINUE READING
