By means of structure-based molecular hybridization strategy, a series of novel diarylpyri(mi)dine derivatives targeting the entrance channel of HIV-1 reverse transcriptase (RT) were designed, synthesized and evaluated as potent non-nucleoside reverse transcriptase inhibitors (NNRTIs). Encouragingly, all the tested compounds showed good activities against wild-type (WT) HIV-1 (IIIB) with EC50 in the range of 1.36 nM–29 nM, which is much better than those of nevirapine (NVP, EC50 = 125.42 nM) and azidothymidine (AZT, EC50 = 11.36 nM). Remarkably, these compounds also displayed effective activity against the most of the single and double-mutated HIV-1 strains with low EC50 values, which is comparable to the control drugs. Besides, these compounds were also exhibited favorable enzymatic inhibitory activity. Moreover, preliminary structure-activity relationships (SARs) and molecular modeling study were investigated and discussed in detail. Unexpectedly, four diarylpyrimidines yielded moderate anti-HIV-2 activities. To our knowledge, this is rarely reported that diarylpyrimidine-based NNRTIs have potent activity against both HIV-1 and HIV-2 in cell culture.
