Molecular van der Waals space and topological indices from the distance matrix.
A comparative study of 36 molecular descriptors derived from the topological distance matrix and van der Waals space is carried out within this paper. They are partitioned into 16 generalized… Expand

QSAR MODELLING OF ANTI-HIV ACTIVITY WITH HEPT DERIVATIVES
We performed studies upon an extended series of 79 HEPT ligands (1-[(2hydroxyethoxy)methyl]-6-(phenylthio)thymine), inhibitors of HIV reverse-transcriptase – RT, with anti-HIV biological activity,… Expand

Comparison of the Minimal Steric Difference (MTD) and Comparative Molecular Field Analysis (CoMFA) Methods for Analysis of Binding of Steroids to Carrier Proteins
Cross validation and results with test series indicate similar predictive power for the CoMFA and the much less CPU-time consuming MTD method. We present an MTD analysis for the binding of a series… Expand

Quantitative relationships for the prediction of the vapor pressure of some hydrocarbons from the van der Waals molecular surface
A quantitative structure-property relationship (QSPR) modeling of vapor pressure at 298.15 K, expressed as log (VP / Pa) was performed for a series of 84 hydrocarbons (63 alkanes and 21 cycloalkanes)… Expand

QSAR by Minimal Topological Difference[s]. Post-Modern Perspectives.
TLDR
In the context of reconsidering the quantitative structure-activity relationship (QSAR) methods at the economically level, vis the optimization rules of OECD, the present review unfolds the key features of Minimal Sterical, Monte-Carlo, and Minimal Topological Difference (MTD) methods, developed for the quantitative treatment of the relations between biological chemical compounds (drugs, pesticides, and so on) and their structures.
