Abstract
In this study, the partition coefficients (Log P) of two series of isoindolines-2-substituted were calculated from the equation obtained for the multilinear correlation between the electronic properties: the highest occupied molecular orbital and the lowest unoccupied molecular orbital energies, and the steric property volume, and the experimental Log P values were determined for some representative isoindolines. Log P values calculated under quantum chemistry were compared with Log P values obtained by the Log P calculation software ALOGPS 2.1 server; the Log P values calculated showed a better correlation with experimental Log P values than those obtained by means of the software. Log P values calculated were also correlated with the antiproliferative activity of some isoindolines-2-substituted determined on HeLa cells, and the correlation obtained shows a quadratic relationship between Log P values calculated and the antiproliferative activity of isoindolines-2-substituted, suggesting a significant effect of Log P values on biological activity of isoindolines.
