“…20 The application of descriptors derived from the energy of frontier orbitals has a long history in QSAR and QSPR involving small training sets. 21 More recent examples are models for the prediction of bioconcentration factors, 22 rate constants of oxidations of organic contaminants, 23 thiol reactivity and toxicity of water disinfection byproducts, 24,25 and aromatase inhibition. 26 Alternatives to the computationally demanding DFT calculations can be envisaged to obtain energies of frontier orbitals and other valuable properties for whole molecules, bonds, or atoms.…”

“…ChemAxon provides the calculation plugins of invoking function API, so our lab members have made a careful study and repeated experiments. The calculation results are compared with the ones of Gaussian 09 [18], JChem for Excel [34], HyperChem 7.5 [20, 36], and Dragon [37] programs calculation. By invoking the Calculator Plugins and using the Java language, we successfully developed a convenient and available customized batch calculation program (second development software) for the small molecular descriptors.…”

“…Moreover, several efforts by using computational and mathematical approaches have been made in investigating small molecules of DPP-4 inhibitors. In our previous studies [17], we have attempted to use the quantum chemistry method [18] to optimize a series of DPP-IV inhibitors, and a 2D-QSAR model has been built, which can predict the inhibitory activity of small molecule with satisfying results. However, it is time consuming to calculate the molecular descriptors adopted in 2D-QSAR model.…”

“…Quantitative structure-property relationship (QSPR) studies have been successfully used for the prediction of physicochemical properties of chemical compounds based on their structures (19)(20)(21)(22)(23)(24). The biological counterpart of such studies, quantitative structure-activity relationships (QSAR), has also been extensively used with great success (25)(26)(27)(28).…”
