Struct.-Act. Relat., 25, 317 (2006) [5] J. Huuskonen, Eur. J. Med. Chem., 35, 1081 (2000) Each molecule is encoded as a vector of molecular descriptors (40 descriptors taken from JOELib2) which makes it possible to regard it as a point in a 40 dimensional space. In this space various approaches to describe the applicability domain can be formulated. We examined a subset of the methods described by Netzeva in [1]:

A novel topological descriptor based on the expanded wiener index: Applications to QSPR/QSAR studies

In this paper, a novel topological index, named M-index, is introduced based on expanded form of the Wiener matrix. For constructing this index the atomic characteristics and the interaction of the vertices in a molecule are taken into account. The usefulness of the M-index is demonstrated by several QSPR/QSAR models for different physico-chemical properties and biological activities of a large...

Notes on quantitative structure-properties relationships (QSPR) (1): A discussion on a QSPR dimensionality paradox (QSPR DP) and its quantum resolution

Classical quantitative structure-properties relationship (QSPR) statistical techniques unavoidably present an inherent paradoxical computational context. They rely on the definition of a Gram matrix in descriptor spaces, which is used afterwards to reduce the original dimension via several possible kinds of algebraic manipulations. From there, effective models for the computation of unknown pro...

A Novel Molecular Descriptor Derived from Weighted Line Graph

The Bertz indices, derived by counting the number of connecting edges of line graphs of a molecule were used in deriving the QSPR models for the physicochemical properties of alkanes. The inability of these indices to identify the hetero centre in a chemical compound restricted their applications to hydrocarbons only. In the present work, a novel molecular descriptor has been derived from the w...
