Specification
The compound JTT-501 is a unique isoxazolidinedione derivative which stands apart from thiazolidinediones like pioglitazone and troglitazone because of its structure. The study examined how JTT-501 affected insulin sensitivity and functioned within rodent models of diabetes.
Key Findings
· The compound JTT-501 demonstrated enhanced insulin-stimulated differentiation of 3T3-L1 fibroblasts with an effective concentration of 110 nM. JTT-501 showed activation properties on peroxisome proliferator-activated (PPA) γ and α receptors at EC5-fold concentrations of 0.28 and 5.4 μM.
· JTT-501 successfully reduced hyperglycemia and hyperinsulinemia while lowering hypertriglyceridemia levels and strengthened insulin-triggered glucose oxidation in adipose tissues of KK-Ay mice which represent non-insulin-dependent diabetes mellitus.
· JTT-501 demonstrated efficacy in the non-insulin-dependent diabetes mellitus model using Zucker diabetic fatty (ZDF) rats yet failed to show effectiveness in the insulin-dependent diabetes model of streptozotocin-induced diabetic mice.
· The findings demonstrate that JTT-501 increases insulin responsiveness in peripheral tissues and decreases hyperglycemia, hyperinsulinemia, and hypertriglyceridemia in non-insulin dependent diabetes mellitus models. JTT-501 exhibits a unique ability to reduce triglyceride levels which sets it apart from thiazolidinediones. JTT-501 shows potential as an antidiabetic medication for patients with non-insulin-dependent diabetes who experience insulin resistance.
Phosphodiesterase (PDE) 3B serves as a primary enzyme that drives insulin's anti-lipolytic action within adipocytes. The activation of PDE3B results in decreased free fatty acid (FFA) output and high serum FFA levels lead to insulin resistance. This study identified the reduced expression of PDE3B gene specifically in adipose tissue from KKAy mice. Then, researchers examined how JTT-501, which is a peroxisome proliferator-activated receptor (PPAR)γ ligand, affected PDE3B gene expression.
Key Findings
· Research revealed that mRNA levels of PDE3B together with protein counts and membrane-bound PDE activity in KKAy mice adipose tissues reduced to 47%, 57% and 51% compared to C57BL/6J control mice values.
· In untreated KKAy mice JTT-501 elevated levels of PDE3B mRNA by 2.2-fold and protein levels by 1.6-fold and membrane-bound PDE activity by 1.7-fold. In KKAy mice liver tissue PDE3B gene expression showed no alteration and treatment with JTT-501 did not produce any effects. JTT-501 lowered elevated serum levels of insulin, glucose, FFA, and triglycerides in KKAy mice.
· The adipose tissues of KKAy mice exhibited specific downregulation of PDE3B gene expression. The administration of JTT-501 restored lowered gene expression levels and led to better insulin resistance while also decreasing elevated serum FFA levels.
