Abstract
The cytotoxic activities of a series of HEPT analogues were modeled using 1x, Vw, Xeq along with indicator parameters. Based on the dominance of electro-negativity the data set of 59 compounds has to be divided into two subsets consisting of 48 and 11 compounds respectively. The latter subset was dominated by electronegativity effect (Xeq). Excellent results are obtained in multi-parametric regressions and are discussed critically.
