Abstract
A series of 47 indole-3-carboxamide derivatives with their renin inhibitors were subjected to QSAR to derive a correlation between biological activity as a dependent variable and various descriptors as independent variables. The best 2D-QSAR model having cross-validated squared correlation coefficient q 2 = 0.7847 with external predictive of pred_r 2 = 0.8193. Based on k-nearest neighbor method the results some key structural factors responsible for renin inhibitors of this series of compounds were revealed as follows: the substituent R1 should have higher steric potential is favorable and substituent R2, and R3 position electron donating group may be favorable. The structural insights gleaned from the study could be usefully employed to design activators with a much more enhanced potency.
