A convenient strategy to functionalize carbon nanotubes with ascorbic acid and its effect on the physical and thermomechanical properties of poly(amide–imide) composites
Synthesis, antimicrobial, and QSAR studies of substituted benzamides
摘要:
A series of new substituted benzamides were synthesized and tested in vitro for their antibacterial activity against Grampositive and Gram-negative bacteria and as well for antifungal activity. The compounds 8i and 9 showed better activity among the different benzamides synthesized. The structural characteristics governing antibacterial activities of substituted benzamides were studied using QSAR methodology. The results showed that the antimicrobial activity could be modeled using the topological descriptors, molecular connectivity indices ((2)chi(v) and (2)chi) and Kiers shape index (kappa alpha(1)). The low residual activity and high cross-validated r(2) values (r(cv)(2)) observed indicated the predictive ability of the developed QSAR models. (C) 2007 Elsevier Ltd. All rights reserved.
