Bivalent inhibition of β-Tryptase: distance scan of neighboring subunits by dibasic inhibitors
摘要:
Based on bifunctional diketopiperazines as templates and m-aminomethyl-phenylalanine as arginine mimetic, we have synthesized a new class of structurally related dibasic tryptase inhibitors with systematically increasing spacer length. These compounds were used to scan the distance between the active sites of two neighboring subunits of the beta-tryptase tetramer. The K-i-values obtained are a function of the distance between the terminal amino groups and indicate optimal binding of inhibitors with 29-31 bonds between the amino groups. These experimental data are in full agreement with predictions derived from a novel modeling program that allows the docking of bivalent ligands. (C) 2002 Elsevier Science Ltd. All rights reserved.

reactivity is the utilization of pyridinium salt‐activated alkylamines, with a base as a promoter. The transformation exhibits good functional group compatibility, and includes inexpensive primary amine feedstocks and aminoacids. The proposed method can serve as a powerful synthetic method for late‐stage modification of complex compounds. Mechanistic experiments suggest that free radical processes are
