Thiocarbamates as non-nucleoside HIV-1 reverse transcriptase inhibitors: docking-based CoMFA and CoMSIA analyses

Description

Thiocarbamates (TCs) have been recently identified as a new class of potent non-nucleoside HIV-1 Reverse Transcriptase (RT) inhibitors. A computational strategy based on molecular docking studies, followed by CoMFA and CoMSIA analyses, has been used to elucidate the atomic details of the RT/TC interactions and to identify the most important features impacting the TC antiretroviral activity. The CoMFA model resulted to be the more predictive, and gave r2= 0.93, rcv2 = 0.53, SEE= 0.292, F =180, and rtest2= 0.70. The 3D-QSAR field contributions and the structural features of the RT binding site showed a good correlation. These studies will be useful to design new TCs with improved potency also against clinically relevant resistant mutants.
