QSAR study on benzenesulphonamide carbonic anhydrase inhibitors has been made using the most discriminatory Balaban index (J). The regression analysis has shown that even in monoparametric regression this index gave excellent results. Furthermore, using the combination of the Balaban Index (J) with the first-order Randic connectivity index ((1)chi) and(More)
The supramolecular complexing ability vis-à-vis pKa estimation of a large series of 43 sulfonamides was made using a series of molecular descriptors including topological indices. The set of topological indices chosen also contains Balaban (J) and a variety of Balaban type indices: J, Jz, Jm, Jv, Jc, and Jp. The results have shown that the most(More)
QSAR studies on 104 flavonoid derivatives as p56lck protein tyrosine kinase inhibitors were performed using hydration energy and logP as predictor parameters. The results obtained demonstrate in detail, which specify that hydration energy and hydrophobic parameters of the compounds play a significant role in developing QSAR models. The significance of(More)
The paper describes the dominating role of surface tension (ST) on the modeling, monitoring, and estimating pK(a) for a large series of 43 substituted sulfonamides. Because of the direct correlation of ST with parachor (Pc) vis-a-vis molecular volume (MV), ST is considered as a steric parameter. Single as well as multi-parametric regressions have indicated(More)
The phenolic activity (log 1/C) of a large series of phenols against L1210 leukaemia cells was modelled using physicochemical parameters other than conventional electronic and steric parameters. Attempts have also been made to examine need or otherwise of the hydrophobic parameter, log P, in such studies. The results have shown that contribution of log P in(More)
In the present study, effort has been made to develop a mathematical model for the set of 19 (tetrahydromidazo [4,5,1-jk][1,4] benzodizepin-2(1H)-one) (TIBO) derivatives. The biological activity modeled in the present investigation is cytotoxic concentration (log 1/C). To investigate the cytotoxic behavior of TIBO derivatives, classical and nonconventional(More)
This work describes QSAR and SAR studies on the inhibition of reverse transcriptase by 31 novel DAPY (diarylpyrimidine) derivatives using both topological and physicochemical properties and molecular modelling parameters along with indicator parameters. The application of a multiple linear regression analysis indicated that a combination of topological and(More)
The present study reports the QSAR modeling of benzodiazepine receptor binding affinity (pIC(50)) for a large set of 70 benzodiazepine receptor ligands. The step-wise regression analysis indicated that out of the large pool of molecular descriptors used only hydration energy (He), hydrophobic parameter (pi(3,5)), steric parameter (E(s)(2,6)) are useful for(More)
Quantitative Structure-Activity Relationship (QSAR) studies on a series of psychotomimetic phenylalkylamines have been made using a combination of Minimum Topological Difference (MTD) method and topological methodology. The topological indices used being a pool of distance-based topological indices. The regression analyses have shown that excellent results(More)
This work describes QSAR and SAR studies on the reduction of 27 aromatic nitro compounds by xanthine oxidase using both distance-based topological indices and quantum molecular descriptors along with indicator parameters. The application of a multiple linear regression analysis indicated that a combination of distance-based topological indices with the ad(More)
