Based on the results of X-ray analysis of the complex between Suc-Gln-Val-Val-Ala-Ala-pNA, a fairly potent thiol proteinase inhibitor, and papain, iNoc-Gln-Val-Val-Ala-Ala-pNA was designed and prepared and its inhibitory activity against thiol proteinases was examined. iNoc-Gln-Val-Val-Ala-Ala-pNA inhibited cathepsin L fairly specifically, although its potency is not high.
基于X射线分析的结果,Suc-Gln-Val-Val-Ala-Ala-pNA和木瓜蛋白酶iNoc-Gln-Val-Val-Val-Ala-Ala-pNA之间的复合物非常有效设计并制备了其,并研究了其对硫醇蛋白酶的抑制活性。尽管iNoc-Gln-Val-Val-Val-Ala-Ala-pNA的效力并不高,但它能相当特异性地抑制组织蛋白酶L。
