Stereo Signature Molecular Descriptor

open access: yesJournal of Chemical Information and Modeling, 2013
We present an algorithm to compute molecular graph descriptors considering the stereochemistry of the molecular structure based on our previously introduced signature molecular descriptor. The algorithm can generate two types of descriptors, one which is compliant with the Cahn-Ingold-Prelog priority rules, including complex stereochemistry structures ...

BCL::EMAS — Enantioselective Molecular Asymmetry Descriptor for 3D-QSAR

open access: yesMolecules, 2012
Stereochemistry is an important determinant of a molecule’s biological activity. Stereoisomers can have different degrees of efficacy or even opposing effects when interacting with a target protein.

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

Machine learning models for rat multigeneration reproductive toxicity prediction

open access: yesFrontiers in Pharmacology, 2022
Reproductive toxicity is one of the prominent endpoints in the risk assessment of environmental and industrial chemicals. Due to the complexity of the reproductive system, traditional reproductive toxicity testing in animals, especially guideline ...

A new set of molecular descriptors [PDF]

open access: yesActa Crystallographica Section B Structural Science, 2002
A new set of criteria for quantitative analysis of molecular interactions is proposed, which is based on the conceptions of atomic and molecular Voronoi–Dirichlet polyhedra. It is shown that the calculation of solid angles of ligands and complexes as a whole allows one to estimate screening effects and the probability of forming intra- and intercomplex

On Molecular Descriptors of Carbon Nanocones [PDF]

open access: yesBiomolecules, 2018
Many degree-based topological indices can be obtained from the closed-off M-polynomial of a carbon nanocone. These topological indices are numerical parameters that are associated with a structure and, in combination, determine the properties of the carbon nanocone.

QSAR-QSIIR-based prediction of bioconcentration factor using machine learning and preliminary application

open access: yesEnvironment International, 2023
Bioconcentration factor (BCF) is one of the important parameters for developing human health ambient water quality criteria (HHAWQC) for chemical pollutants. Traditional experimental method to obtain BCF is time-consuming and costly.

On computing minimal realizations of periodic descriptor systems [PDF]

open access: yes, 2007
: We propose computationally efficient and numerically reliable algorithms to compute minimal realizations of periodic descriptor systems. The main computational tool employed for the structural analysis of periodic descriptor systems (i.e., reachability
