The Qsar Study of Azole Derivatives Using Molecular Descriptors for Quantum Molecular States.

open access: yesCurrent health sciences journal, 2016
Azoles are the main antifungal agents currently used in systemic therapy and local mycoses. The class of azole derivatives has been studied using fingerprint descriptors based on electronegativity of the occupied molecular orbitals (OMO) and unoccupied molecular orbitals (UMO).

Propriedades químico-quânticas empregadas em estudos das relações estrutura-atividade Quantum chemical properties used in structure-activity relationship studies

open access: yesQuímica Nova, 2010
In this work we show that structure-activity relationship studies are of great importance in modern chemistry and biochemistry. In order to obtain a significant correlation, it is crucial that appropriate descriptors be employed.

Analyzing Learned Molecular Representations for Property Prediction

open access: yes, 2019
Advancements in neural machinery have led to a wide range of algorithmic solutions for molecular property prediction. Two classes of models in particular have yielded promising results: neural networks applied to computed molecular fingerprints or expert-

Prediction of the retention of β-diketonato complexes in TLC systems on silica gel by quantitative structure–retention relationships [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Quantitative structure–retention relationships for a series of 30 mixed β-diketonato complexes of cobalt(III), chromium(III) and ruthenium(III) were derived by multiple linear regression analyses using molecular descriptors obtained by quantum chemical ...

Molecular interaction fields vs. quantum-mechanical-based descriptors in the modelling of lipophilicity of platinum(iv) complexes [PDF]

open access: yesDalton Trans., 2013
We report QSAR calculations using VolSurf descriptors to model the lipophilicity of 53 Pt(iv) complexes with a diverse range of axial and equatorial ligands. Lipophilicity is measured using an efficient HPLC method. Previous models based on a subset of these data are shown to be inadequate, due to incompatibility of whole molecule descriptors between ...

Adapting the Interrelated Two-way Clustering method for Quantitative Structure-Activity Relationship (QSAR) Modeling of a Diverse Set of Chemical Compounds

open access: yes, 2013
Interrelated Two-way Clustering (ITC) is an unsupervised clustering method developed to divide samples into two groups in gene expression data obtained through microarrays, selecting important genes simultaneously in the process.

Quantum similarity of isosteres coordinate versus momentum space and influence of alignment [PDF]

open access: yes, 2010
: Molecular quantum similarity was studied for a set of peptide isosteres analyzed before by Boon et al. (Chem. Phys. Lett., 1998, 295 122). Overlap and Coulomb similarity measures in coordinate space were calculated using the TGSA (Topo-Geometrical ...
