A 2,4-thiazolidinedione derivative of the formula (I): ##STR1## wherein R is an optionally substituted hydrocarbon group or heterocyclic group which may be attached through a hydrocarbon chain; n is 0 or 1; X is CH or N; Y is a bivalent hydrocarbon group; R.sup.1 and R.sup.2 are the same or different and are a hydrogen atom, a halogen atom, an optionally substituted hydroxyl group or an optionally substituted hydrocarbon group, and either R.sup.1 or R.sup.2 and a part of Y may be linked together to form a ring; and L and M are a hydrogen atom, or L and M are linked together to form a bond; or a salt thereof. A pharmaceutical composition comprising the compound (I) and a process for producing the compound (I) are also provided.
Novel 2,4-oxazolidinedione compounds of the formula: ##STR1## wherein R is a hydrocarbon residue or a heterocyclic group each of which may be substituted; Y is --CO--, --CH(OH)-- or --NR.sup.3 -- (wherein R.sup.3 is an alkyl group which may be substituted); m is 0 or 1; n is 0, 1 or 2; X is CH or N; A is bivalent straight or branched hydrocarbon chain residue having 1 to 7 carbon atoms; R.sup.1 and R.sup.2 each are hydrogen or an alkyl group, or R.sup.1 and R.sup.2 are combined with each other to form a 5- to 6-membered heterocyclic group optionally containing nitrogen; L and M each are hydrogen, or L and M are combined with each other to form a bond, or pharmaceutically acceptable salts thereof, having excellent hypoglycemic and hypolipidemic activities and are useful as anti-diabetics or hypolipidemic agents.

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
制备了在5位具有ω-(偶氮基烷氧基苯基)烷基取代基的两类新的2,4-噻唑烷二酮和2,4-恶唑烷二酮,并在两个遗传性肥胖和糖尿病动物模型KKA(y)中评估了它们的抗糖尿病作用小鼠和Wistar脂肪大鼠。大量的2,4-硫杂恶唑烷二酮显示出有效的降糖和降脂活性。2,4-恶唑烷二酮的抗糖尿病活性优于2,4-噻唑烷二酮的抗糖尿病活性。在这些化合物中,5- [3- [4- [2-(2-呋喃基)-5-甲基-4-恶唑基甲氧基] -3-甲氧基苯基]丙基] -2,4-恶唑烷二酮的两种对映体(64)就活性而言,最有趣的化合物是通过使用固定化脂肪酶对相应的α-羟基戊酸酯(26)进行不对称O-乙酰化合成的,然后将恶唑烷二酮环环化。(R)-(+)-64比(S)-(-)-64(ED25> 1.5 mg / kg / d)表现出更强的降糖活性(有效剂量(ED)25 = 0.561 mg / kg / d) )或吡格列酮(ED25
