摘要：

Thirteen candidate irreversible inhibitors derived from N-benzyl- or N-phenyl-α-(2-carboxy-4-chlorophenoxy)-acetamide with a terminal SO2F group on the N substituent were synthesized and evaluated. A number of these at a Ki concentration gave essentially complete inactivation of α-chymotrypsin in 60 min at 37°. The best compound was α-(2-carboxy-4-chlorophenoxy)-N-[m-(m-fluorosulfonylphenyluieido)benzyl] acetamide (7) which showed a half-life of inactivation of 2 min when a Ki = 81 μM concentration was incubated with 1 μM chymotrypsin. © 1969, American Chemical Society.
