wild-type DENV-2 virus. The linear dipeptide compound 1 and the non-peptidic fused ring compound 2 show comparable activities against DENV-2 NS2B-NS3 protease and wild-type DENV-2 virus in a viral replication assay. The preliminary SAR reveals that a substituent and its stereochemistry at C-3 position, substitution (X) at N-2 arene and a linker (Y) between C-3 position and its attached arene are important
针对DENV-2 NS2B-NS3蛋白酶和野生型DENV-2病毒,设计,合成,表征和测定了一系列吡咯烷和咪唑啉酮的稠合环衍生物。在病毒复制测定中,线性二肽化合物1和非肽稠环化合物2显示出对DENV-2 NS2B-NS3蛋白酶和野生型DENV-2病毒的可比活性。初步SAR显示,取代基及其在C-3位的立体化学,在N-2芳烃处的取代(X)以及在C-3位置及其连接的芳烃之间的连接基(Y)对于吡咯烷菌素的稠合环骨架很重要。 [1,2- c咪唑啉酮可阻断NS2B-NS3蛋白酶的活性位点。这种有前途的结构核心将有助于发现非肽类有效的NS2B-NS3蛋白酶抑制剂,以阻止登革热病毒感染。
