摘要:Through a structure-guided core-refining approach, a series of novel imidazo[1,2-a]pyrazine derivatives were designed, synthesized and evaluated as HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs). Biological results of antiviral assay in MT-4 cell cultures showed that 12 target compounds displayed moderate activities against wild-type (wt) HIV-1 strain (IIIB) with EC50 values ranging from 0.26 mu M to 19 JAM. Among them, 4a and 5a were found to be the two most active analogues possessing EC50 values of 0.26 mu M and 0.32 mu M respectively, comparable to delavirdine (DLV, EC50 = 0.54 mu M) and nevirapine (NVP, EC50 = 0.31 mu M) in a cell-based assay. Additionally, 9 compounds showed RI inhibitory activity superior to that of NVP. Moreover, some predicted drug-like properties of representative compounds 4a and 5a, as well as the structure-activity relationship (SAR) analysis were discussed in detail. The binding mode of compound 4a was investigated by molecular simulation studies. (C) 2015 Elsevier Masson SAS. All rights reserved.
