title: Substituted dihydrobenzopyran and dihydrobenzofuran thiazolidine-2,4-diones as hypoglycemic agents.
abstract: A series of dihydrobenzofuran and dihydrobenzopyran thiazolidine-2,4-diones (compounds 3-26) was synthesized from the corresponding aryl aldehydes 1 in two steps. These compounds represent conformationally restricted analogues of the novel hypoglycemic ciglitazone. The series was evaluated by hypoglycemic effects in vitro by measuring stimulation of 2-deoxyglucose uptake in L6 myocytes and stimulation of expression of the glucose transporter protein in 3T3-L1 adipocytes. In vivo hypoglycemic effects were evaluated in the genetically obese ob/ob mouse, and structure-activity relationships are discussed. On the basis of this in vivo potency, we have selected the 2(R)-benzylbenzopyran derivative to be further studied in a clinical setting.
