for their inhibitory properties. Among them, compound 7c (4-(morpholin-4-yl)-6-[4-(trifluoromethoxy)anilino]-1,3,5-triazine-2-carbonitrile) was identified as the most potent and selective inhibitor of cathepsin S (Ki = 2 ± 0.3 nM). Also 7c impaired the autocatalytic maturation of procathepsin S. Molecular docking studies support that 7c bound within the active site of cathepsin S, by interacting with
我们在此报告了一系列新的2,4,6-三取代的1,3,5-三嗪作为人类半胱氨酸组织蛋白酶的可逆抑制剂的合成和生物学评估。从市售的三氯三嗪分三到四个步骤分别得到所需的带有吗啉和N- Boc哌啶的产物。在体外针对各种组织蛋白酶的抑制特性评估了17种迄今未知的化合物。其中,化合物7c(4-(吗啉-4-基)-6- [4-(三氟甲氧基)苯胺基] -1,3,5-三嗪-2-腈)被确定为组织蛋白酶最有效和选择性的抑制剂S(Ki = 2±0.3 nM)。此外7C受损蛋白原S.分子对接研究的自催化成熟支持7C 通过与Gly23,Cys25和Trp26(S1子位点),Asn67,Gly69和Phe70(S2子位点)以及Gln19(S1'口袋)相互作用,结合在组织蛋白酶S的活性位点内。
