Abstract:
E-2-Arylmethylen-1- tetralones and E-3-phenylme thylene chromanone-4-ones and their derivatives closely related to flavonoids belong to the plant secondary metabolites most investigated recently.The class of flavonoids is an enormous class of plant secondary metabolites having so different pharmacological effects as inhibition of nitric oxide synthase cancer preventive effect or potential impact on the etiology of certain vascular disease. Numerous biological activity have been attributed to the tetralones mentioned. In this study B3P8 6/6- 31++G* was used to compute and map the molecular surface electrostatic potentials of a group of tetralones and chromanones to identify common features related to their lipophilicity. Several statistical properties including potentials extrema (Vs,min, Vs,max), the average of positive electrostatic potential on the surface (Vs t), the average of V(r), over the surface (Vs) and the variance of V(r) over the surface (62-) and system lipophilicity werecomputed. Statistically, the most significant correlation is a three parameter equation with correlation coefficient, R value of 0.881 and R2adj=0.743. The obtained models allowed us to reveal lipophilicity activity of tetralones
