We investigated whether benefits could be achieved on insulin sensitivity and lipid metabolism by the dual PPAR\u03b1\/\u03b3 agonist ragaglitazar in high fat-fed rats. Ragaglitazar completely eliminated high-fat feeding-induced liver triglyceride accumulation and visceral adiposity, like the PPAR\u03b1 agonist Wy-14643 but without causing hepatomegaly. In contrast, the PPAR\u03b3 agonist rosiglitazone only slightly lessened liver triglyceride without affecting visceral adiposity. Compared with rosiglitazone or Wy-14643, ragaglitazar showed a much greater effect (79%, P&lt; 0.05) to enhance insulin's suppression of hepatic glucose output. Whereas all three PPAR agonists lowered plasma triglyceride levels and lessened muscle long-chain acyl-CoAs, ragaglitazar and rosiglitazone had greater insulin-sensitizing action in muscle than Wy-14643, associated with a threefold increase in plasma adiponectin levels. There was a significant correlation of lipid content and insulin action in liver and particularly muscle with adiponectin levels ( P &lt; 0.01). We conclude that the PPAR\u03b1\/\u03b3 agonist ragaglitazar has a therapeutic potential for insulin-resistant states as a PPAR\u03b3 ligand, with possible involvement of adiponectin. Additionally, it can counteract fatty liver, hepatic insulin resistance, and visceral adiposity generally associated with PPAR\u03b1 activation, but without hepatomegaly.
