A Correlation of the Drug Activities (Anti-bacterial) in the Structure of Some Hetero Cyclic Compound Containing Benzimidazole and Beta-lactam Moiety in Terms of the Density Functional Descriptors � A QSAR and QSPR Study

Abstract

Present study shows the correlation of activity of as many as 13 Anti-bacterial (containing benzimidazole and beta-lactam moiety) drugs in terms of global reactivity descriptors under paradigm of QSPR/QSAR study. Investigation of antimicrobial activity of the compounds was done by using Gram- positive (S. aureus, S. mutans and B. subtilis) bacteria. The global descriptors nicely correlate the variation of activity with structures of the drug molecules
