Abstract

Databases used in 2D-QSAR model included 592 compounds with a wide variety of derivatives. Of these, 132 compounds were derivatives of quinolin, 75 compounds of benzimidazole and 100 compounds were from the University of Tokyo Library. Building 2D-QSAR models used the partial least squares algorithm (PLS) in MOE 2014.09 software. Three 2D-QSAR models were built based on 2D molecular descriptors parameters with R2, Q2, RMSE, CCC values which were respectively 0,79; 0,76; 0,20; 0,88 for QSAR model derivatives of quinolin (1); 0,79; 0,73; 0,10; 0,88 for QSAR model derivatives of benzimidazole (2) and 0,79; 0,76; 0,13; 0,88 for QSAR model of compounds from the University of Tokyo Library (3). Virtual screening from 57423 compounds of TCM database by three 2D-QSAR models showed that 228 compounds (IC50 ≤ 10 µM) corresponded with the model (1), 5252 compounds (IC50 ≤ 10 µM) corresponded with the model (2), 313 compounds (IC50 ≤ 15 µM) corresponded with the model (3) having highly anti-haemozoin activities.
