Thiazolidinedione derivatives are antidiabetic agents that increase the insulin sensitivity of target tissues in animal models of non-insulin-dependent diabetes mellitus. In vitro, thiazolidinediones promote adipocyte differentiation of preadipocyte and mesenchymal stem cell lines; however, the molecular basis for this adipogenic effect has remained unclear. Here, we report that thiazolidinediones are potent and selective activators of peroxisome proliferator-activated receptor gamma (PPAR gamma), a member of the nuclear receptor superfamily recently shown to function in adipogenesis. The most potent of these agents, BRL49653, binds to PPAR gamma with a Kd of approximately 40 nM. Treatment of pluripotent C3H10T1/2 stem cells with BRL49653 results in efficient differentiation to adipocytes. These data are the first demonstration of a high affinity PPAR ligand and provide strong evidence that PPAR gamma is a molecular target for the adipogenic effects of thiazolidinediones. Furthermore, these data raise the intriguing possibility that PPAR gamma is a target for the therapeutic actions of this class of compounds.[1]

Diabetes with vascular complication needs strict interventions to retard possible serious complications. This research estimated the possible interaction of rosiglitazone (RGN) with losartan (Los) in diabetic rats. Male Sprague-Dawley rats were randomly divided into nondiabetic rats, diabetic rats, and diabetic rats that received RGN, Los, or a combination of RGN and Los. Measurement of serum glucose, vascular adhesion molecule-1, interleukin-6, tumor necrosis factor-α, aortic lipid peroxide (malondialdehyde), glutathione, superoxide dismutase, and total nitrate/nitrite levels was done. Also, the effects of RGN on the relaxation created by acetylcholine and sodium nitroprusside, contraction of isolated aortic rings provoked by phenylephrine and angiotensin II were determined. Results revealed that RGN or Los had a vasodilating effect to variable degrees indicated by enhanced effects on both acetylcholine-induced relaxation and the antagonistic effect on angiotensin II and phenylephrine-stimulated contraction of diabetic aortas with significant amelioration in serum glucose, vascular adhesion molecule-1, interleukin-6, and tumor necrosis factor-α levels and aortic oxidant/antioxidant balance. Treatment of diabetic rats with a combination of RGN and Los produced a more pronounced effect on the measured parameters compared to the diabetic, RGN-, and Los-treated groups. These findings point out the beneficial effects of RGN and Los combination in diabetic rats.[5]
