Abstract:
CBz-Ala-Ala-Pro-ambo-Val-CF3 (1) was synthesized. The compound inhibits human Leucocyte elastase with Ki = 1.0 x 10(-9) M. This inhibitor is reversible, slow, tight-binding inhibitor with k on = 2 x 10(4) M-1 s-1 k off = 1.9 x 10(-5) s-1. For the solubilization of elastin by HLE by 1 I.C. 50 = 110 nM. This inhibitor is the most effective aldehyde or ketone inhibitor of a serine proteinase yet described.
