Benefits of statistical molecular design, covariance analysis, and reference models in QSAR: a case study on acetylcholinesterase

Abstract: Scientific disciplines such as medicinal- and environmental chemistry, pharmacology, and toxicology deal with the questions related to the effects small organic compounds exhort on biological targets and the compounds’ physicochemical properties responsible for these effects. A common strategy in this endeavor is to establish structure–activity relationships (SARs). The aim of this work was to illustrate benefits of performing a statistical molecular design (SMD) and proper statistical analysis of the molecule… Show more

“…To evaluate the quality of the models two approaches were performed according to reference [26]. Simple linear models using only one basic descriptor (boiling point for the first-dimension and logK OW and the logK OW normalized to the weight of the compound for the second-dimension models) were generated for all four responses.…”

“…In regards to the latter point, viewpoint on targeting AChE as a single target for treating AD is starting to be replaced by the multi-target concept in which the treatment for AD can be approached by a panel of key targets ( Fang et al, 2015 ; Huang et al, 2011 ). Computationally, early studies are predominantly based on simple 2D-QSAR ( Mundy et al, 1978 ; Su & Lien, 1980 ) while later years started to use more sophisticated approach for understanding AChE inhibition encompassing 3D-QSAR ( Deb et al, 2012 ; Lee & Barron, 2016 ; Prado-Prado et al, 2012 ), molecular dynamics ( Shen et al, 2002 ), molecular docking ( Lu et al, 2011 ; Deb et al, 2012 ; Giacoppo et al, 2015 ), pharmacophore modeling ( Lu et al, 2011 ; Gupta & Mohan, 2014 ) and statistical molecular design ( Andersson et al, 2014 ; Prado-Prado, Escobar & Garcia-Mera, 2013 ).…”

“…Cross‐validation (CV) is the most extensively employed validation methods . For the predictive power of the model, and accessing the model fit, squared cross‐validation coefficient for leave–one‐out (Q 2 LOO ) and external validation through test set were used . In the LOO cross‐validation (LOO CV ) method, one of the datasets is randomly deleted.…”
