Abstract: Comparative molecular field analysis (CoMFA), comparative molecular similarity indices
analysis (CoMSIA) and hologram quantitative structure-activity relationship (HQSAR) for 1-[(2-
hydroxyethyloxy)methyl]-6-phenylthio thymidine (HEPT) derivatives were used to have molecular active
conformation selection, molecular alignment, as well as the establishment of corresponding 3D-QSAR
model. The model established by this method had a good ability to predict these compounds. For CoMFA

model, the cross-validated q value and non-cross-validated r value was 0.565 and 0.892, respectively. The
2

best q value for CoMSIA model was 0.636 and r value was 0.953. The most effective HQSAR model was

obtained with q value of 0.876 and r value of 0.929, and the best hologram length value was 97. Seven
highly active HEPT compounds were designed based on three-dimensional contour maps and HQSAR color
code map. Observations derived from these QSAR modeling study may provide a theoretical reference for
designing more active HEPT derivatives.
