QSAR MODELLING OF SOME ANTICANCER PGI50 ACTIVITY ON HL-60 CELL LINES
QSAR (2D and 3D) studies were performed on a series of CAMPTOTHECIN derivatives using Material Studio software (accelrys). QSAR study performed on 102 analogues of which 90 were used in the training set and the rest 22 considered for the test set. QSAR study performed using Genetic function approximation (GFA). GFA method came out with good correlation coefficient 0.837 , cross-validated coefficient 0.792 and R2Test of 0.9408. A highly predictive and statistically significant model was generated. The QSAR models were found to accurately predict the anticancer activity of structurally diverse test set compounds and to yield reliable clues for further optimization of the of CAMPTOTHECIN derivatives in the data set.
