Preliminary in silico investigation of cox 2 selective inhibitors

We report herein an attempt to generate QSAR models for a large number of structurally diverse compounds (1078 compounds) whose affinities for cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) were experimentally determined. Initially, individual QSAR models for COX-1 (M1) and COX-2 (M2) for bio...

Tartalmi kivonat:We report herein an attempt to generate QSAR models for a large number of structurally diverse compounds (1078 compounds) whose affinities for cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) were experimentally determined. Initially, individual QSAR models for COX-1 (M1) and COX-2 (M2) for biological activity were developed. A selectivity QSAR model, M3 was then developed using as dependent variable Y the differences in pIC50 values between COX-1 and COX-2. The statistical results for all three models showed a satisfactory to good statistical parameters where the values for squared correlation coefficient (coefficient of determination) for the training set are: M1: 0.872, M2: 0.797 respectively M3: 0.739. The predicted values of affinity in the case of all three models selected M1, M2 and respectively M3, are very good 84.88%, 91.12%, 79.59% which lead to very small diffrences between observed and predicted biological activity/selectivity (less than 0.5 logarithimic units).
