CoMFA Analysis of tgDHFR and rlDHFR Based on Antifolates with 6-5 Fused Ring System Using the All-orientation Search (AOS) Routine and a Modified Cross-validated r2-guided Region Selection (q2)-GRS) Routine and Its Initial Application

We report the development of CoMFA analysis models that correlate the 3D chemical structures of 80 compounds with 6-5 fused ring system synthesized in our laboratory and their inhibitory potencies against tgDHFR and rlDHFR. In addition to conventional CoMFA analysis, we used two routines available in the literature aimed at the optimization of CoMFA: all-orientation search (AOS) and cross-validated r2-guided region selection (q2-GRS) to further optimize the models.
