Long-acting contraceptive agents: Norethisterone esters of arylcarboxylic acids
摘要:
The synthesis of esters of norethisterone (17 alpha-ethynyl-17 beta-hydroxy-estr-4-en-3-one) with acids containing a benzene ring is described, two methods of esterification being compared in terms of yield and convenience. The activities of these esters as long-acting contraceptive agents have been evaluated.

Discovery of a highly orally bioavailable c-5-[6-(4-Methanesulfonyloxyphenyl)hexyl]-2-methyl-1,3-dioxane-r-2-carboxylic acid as a potent hypoglycemic and hypolipidemic agent
A series of novel 1,3-dioxane-2-carboxylic acid derivatives containing alkyl chain tether and substituted phenyl group as a lipophilic tail have been prepared as agonists of PPAR alpha and gamma. c-5-[6-(4-Methanesulfonyloxyphenyl) hexyl]-2-methyl-1,3-dioxane-r-2-carboxylic acid 13c exhibited potent hypoglycemic and lipid lowering activity with high oral bioavailability in animal models.
