Many 2-oxoalkyl arenesulfonate derivatives having straight or branched alkyl chains of different lengths, 2-oxoalkyl bis-arenesulfonate derivatives, and alkyl arenesulfonate derivatives having a ketal moiety at the 2-position on the alkyl chain were synthesized, and their esterase-inhibitory activities, as well as hypolipidemic activities, were evaluated.Among these compounds, 1-(2, 4, 6-trimethylbenzenesulfonyloxy)-2-dodecanone (III-1u), and 1-(2, 3, 4, 6-tetramethylbenzenesulfonyloxy)-2-hexanone (III-1w), -2-octanone (III-1x) and -2-decanone (III-1y) exhibited potent esterase-inhibitory activities (IC50=3×10-10, 2×10-10, 2×10<-10> and 3×<-11>M, respectively). However, the sulfonate (XV) having a ketal moiety on the alkyl chain and the bis-sulfonate (XVI) exhibited low inhibitory activities toward esterase in comparison with III and XII. Most of the compounds III and some of the compounds XII exhibited potent hypolipidemic activities corresponding to more than 50% lipid-lowering effect (plasma triglyceride and cholesterol ester) in vivo. The structure-activity relatioinships of these compounds are discussed.

Many 1-substituted 2-alkanone derivatives were synthesized and their inhibitory activities toward pancreatic lipase and esterase were examined in order to obtain hypolipidemic agents. 1-Benzenesulfonyloxy-2-pentanone (VI-2a) and 1-(2, 4, 6-trimethylbenzenesulfonyloxy)-2-pentanone (VI-2q) exhibited not only potent and selective esterase inhibitions (IC50 : 9.0×10-7M and 1.0×10-6M, respectively), but also potent hypolipidemic action (90 and 92% reductions of plasma triglyceride, and 53 and 90% reductions of plasma total cholesterol, respectively). A novel working hypothesis is presented to account for the lowering of the plasma lipids level, i.e., that inhibition of esterase and lipase activities in the small intestinal lumen may be responsible for the decrease in the plasma lipids level.
