Troglitazone

A α-tocopherol (vitamin E) moiety containing thiazolidinedione class of insulin-sensitizer that acts as an activator of peroxisome proliferator-activated receptors γ (PPARγ). Also exhibits anti-proliferative and anti-inflammatory properties. Shown to induce cell cycle arrest and apoptosis in human hepatoma cells. Inhibits vascular smooth muscle cell (VSMC) migration by rapidly activating MEK/ERK pathway leading to the induction of c-fos and Ets-1 expression. Blocks PDGF-induced cell proliferation of pancreatic stellate and accelerates p21^Cip1 turnover by inhibiting PKC_δ signaling in VSMCs. Exerts positive inotropic effect via Ca²⁺ sensitization in the sarcoplasmic reticulum and inhibits Na⁺/H⁺ exchange activity and proliferation of macrovascular endothelial cells.

Primary Target
Peroxisome proliferator-activated receptors γ (PPARγ)
