Abstract

Two novel classes of 2,4-thiazolidinediones and 2,4-oxazolidinediones with an omega-(azolylalkoxyphenyl)alkyl substituent at the 5-position were prepared and their antidiabetic effects were evaluated in two genetically obese and diabetic animal models, KKA(y) mice and Wistar fatty rats. A large number of the 2,4-thia(oxa)zolidinediones showed potent glucose- and lipid-lowering activities. The antidiabetic activities of the 2,4-oxazolidinediones were superior to those of the 2,4-thiazolidinediones. Among the compounds, both enantiomers of 5-[3-[4-[2-(2-furyl)-5-methyl-4-oxazolylmethoxy]-3-methoxyphenyl]propyl]-2,4-oxazolidinedione (64), one of the most interesting compounds in terms of activity, were synthesized by using an asymmetric O-acetylation of the corresponding alpha-hydroxyvalerate (26) with immobilized lipase, followed by cyclization of the oxazolidinedione ring. (R)-(+)-64 showed more potent glucose-lowering activity (effective dose (ED)25 = 0.561 mg/kg/d) than (S)-(-)-64 (ED25 > 1.5 mg/kg/d) or pioglitazone (ED25 = 6 mg/kg/d) in KKA(y) mice. It also exhibited a 10-fold more potent antidiabetic activity (ED25 = 0.05 mg/kg/d) than pioglitazone (ED25 = 0.5 mg/kg/d) in Wistar fatty rats. The antidiabetic effects of this compound are considered to be due to its potent agonistic activity for peroxisome proliferator-activated receptor gamma (EC(50) = 8.87 nM).
