REGIOSELECTIVITY AND STEREOSELECTIVITY IN THE INDUCTION OF PEROXISOMEPROLIFERATION BY SUBSTITUTED HEXANOIC ACIDS

Quantitative structure-activity relationship is an effective tool in o rder to predict drug potency. A similar approach is actually developed for peroxisome proliferation induced by substituted carboxylic acids issued from plasticizer metabolism in rats. The study is focused on ac ids found in rat urine after adipic diester dosings. Size, location of the substituted group and length of the chain have been studied. 3-D structure has also been taken in account for 2-ethyl hexanoic acids. T he results obtained so far demonstrate that peroxisome proliferation p otencies of the considered acids are modified according structure chan ges. At this time location of the group along the chain appears to be a predominant factor.
