摘要:
With the aim of discovering potent and selective dengue NS3 protease inhibitors, we systematically synthesized and evaluated a series of tetrapeptide aldehydes based on lead aldehyde 1 (Bz-Nle-Lys-Arg-Arg-H, K-i = 5.8 mu M). In general, we observe that interactions of P, side chain are more important than P, followed by P-3 and P-4. Tripeptide and dipeptide aldehyde inhibitors also show low micromolar activity. Additionally, an effective non-basic, uncharged replacement of P-1 Arg is identified. (c) 2005 Elsevier Ltd. All rights reserved.
