Use

Rosiglitazone maleate, belongs to a novel class of thiazolidine diones launched for the treatment of non-insulin-dependent diabetes mellitus (NIDDM), a disease characterized by a pancreatic β-cell defect and insulin resistance in the liver and peripheral tissues. The racemic base can be obtained by KnSvenagel condensation between 2, 4-thiazolidinedione and the corresponding 4-substituted benzaldehyde (itself prepared in 2 steps from 2-chloropyridine), followed by reduction of the benzylidene. Rosiglitazone was shown to be a potent agonist of peroxisome proliferator activated receptor-gamma (PPARgamma), a nuclear receptor involved in the differentiation of adipose tissue, without activating liver PPAR-alpha receptors. This activation of PPAR-gamma could mediate the down-regulation of leptin gene expression. In animal models, Rosiglitazone has been shown to normalize glucose metabolism and reduce the exogenous dose of insulin needed to achieve glycemic control. In patients with Type II diabetes, daily doses (4 or 8 mg) of Rosiglitazone significantly improved blood sugar control without affecting cardiac structure or function.
