Thiazolidinediones are synthetic peroxisome proliferator-activated receptor γ agonists used to treat type 2 diabetes mellitus. Clinical evidence indicates that thiazolidinediones increase fracture risks in type 2 diabetes mellitus patients, but the mechanism by which thiazolidinediones augment fracture risks is not fully understood. Several groups recently demonstrated that thiazolidinediones s...

Abstract Background Multiple oral insulin-sensitizing agents, such as metformin, thiazolidinediones, inositols, and berberine, have been proven safe efficacious in improving the endocrine, metabolic, reproductive abnormalities seen polycystic ovary syndrome (PCOS), providing more options for healthcare providers patients. These insulin sensitizers are convenient, practical, economic than agents...

A series of erythrose, ribose, and substituted pyrrolidine containing 2,4-thiazolidinediones were synthesized. Among them, thirteen unsaturated thiazolidinediones, six saturated thiazolidinediones and two unsaturated malonates were evaluated for their ability to enhance glucose utilization in cultured L6 myocytes. On the basis of the in vitro activity, 5-[4-[2-(1-benzyl-3,4-bis-benzyloxypyrroli...

Rosiglitazone and pioglitazone are thiazolidinediones used for treatment of noninsulin-dependent diabetes mellitus. These compounds, along with troglitazone, were evaluated for the ability to induce cytochrome P450 enzymes (P450) in primary human hepatocyte cultures and to inhibit P450 in human microsomes. In induction studies, all three thiazolidinediones caused a dose-dependent increase in CY...

Thiazolidinediones or glitazones specifically target insulin resistance. They have proven efficacy for reducing plasma glucose levels of type 2 diabetic patients treated with diet alone, sulphonylureas, metformin or insulin. In addition, they may be associated to some improvement of cardiovascular risk profile. However, troglitazone, the first compound approved by the FDA in the US, proved to b...

The U.S. Food and Drug Administration-approved thiazolidinediones pioglitazone and rosiglitazone are peroxisome proliferator-activated receptor-γ (PPARγ) agonists developed to control serum glucose in patients with diabetes. They have been found to reduce proteinuria and microalbuminuria in both diabetic nephropathy and nondiabetic glomerulosclerosis. We hypothesized that the renal protective e...

The thiazolidinediones exert their insulin sensitising effect by binding to the nuclear receptors (transcription factors) peroxisome proliferator activated receptor (PPAR) γ and, to varying degrees, to PPARα. Several different genes are activated by thiazolidinediones, many of which contribute to the increase in insulin sensitivity (eg. an increase in glucose uptake and utilisation, a decrease ...

BACKGROUND Thiazolidinediones are oral diabetes medications that selectively activate peroxisome proliferator-activated receptor gamma and have potent anti-inflammatory properties. While a few studies have found improvements in pulmonary function with exposure to thiazolidinediones, there are no studies of their impact on asthma exacerbations. Our objective was to assess whether exposure to thi...
