A novel molecular descriptor selection method in QSAR classification model based on weighted penalized logistic regression

open access: yesJournal of Chemometrics, 2017
Molecular descriptor selection is a pivotal tool for quantitative structure–activity relationship modeling. This paper proposes a novel molecular descriptor selection method on the basis of taking into account the information of the group type that the ...

A New Graph-Based Molecular Descriptor Using the Canonical Representation of the Molecule [PDF]

open access: yesThe Scientific World Journal, 2014
Molecular similarity is a pervasive concept in drug design. The basic idea underlying molecular similarity is the similar property principle, which states that structurally similar molecules will exhibit similar physicochemical and biological properties.

A Shape Descriptor for Fast Complementarity Matching in Molecular Docking

open access: yesIEEE/ACM Transactions on Computational Biology and Bioinformatics, 2011
This paper presents a novel approach for fast rigid docking of proteins based on geometric complementarity. After extraction of the 3D molecular surface, a set of local surface patches is generated based on the local surface curvature.

Developing a methodology for an inverse quantitative structure-activity relationship using the signature molecular descriptor

open access: yesJournal of Molecular Graphics and Modelling, 2002
The concept of signature as a molecular descriptor is introduced and various topological indices used in quantitative structure-activity relationships (QSARs) are expressed as functions of the new descriptor.

Antimalarial Drug Predictions Using Molecular Descriptors and Machine Learning against Plasmodium Falciparum

open access: yesBiomolecules, 2021
Malaria remains by far one of the most threatening and dangerous illnesses caused by the plasmodium falciparum parasite. Chloroquine (CQ) and first-line artemisinin-based combination treatment (ACT) have long been the drug of choice for the treatment and

Comparison of Descriptor- and Fingerprint Sets in Machine Learning Models for ADME-Tox Targets

open access: yesFrontiers in Chemistry, 2022
The screening of compounds for ADME-Tox targets plays an important role in drug design. QSPR models can increase the speed of these specific tasks, although the performance of the models highly depends on several factors, such as the applied molecular ...

Large-Scale Evaluation of Collision Cross Sections to Investigate Blood-Brain Barrier Permeation of Drugs

open access: yesPharmaceutics, 2021
Successful drug administration to the central nervous system requires accurate adjustment of the drugs’ molecular properties. Therefore, structure-derived descriptors of potential brain therapeutic agents are essential for an early evaluation of ...
