Active-site-directed alkylation of chymotrypsin by reagents utilizing various departing groups.

Affinity-labeling reagents are useful for the inactivation of proteases in vivo but are apparently limited in application by the possibility of side reactions. In addition, increased specificity would be desirable. Substrate-derived chloromethyl ketones, one class of protease inhibitors, have been examined with the hope that replacement of the departing group halogen by other substituents might lead to improved inhibitor characteristics. Analogues of Z-Phe-Ch2X were synthesized in which X is a sulfonate or carboxylate substituent and examined as inactivators of chymotrypsin. The sulfonate esters were found to be more reactive than the previously studied halogen derivatives.
