PD166793 is a broad spectrum, but class-selective, MMP inhibitor (low nM at MMP-2 & 3 and low μM at MMP-1, 7 & 9). Adding PD166793 to the high-fat diet substantially reduced the rise in blood glucose. The improvement of glucose homeostasis in PD166793-treated ZDF rats was a result of the enhancement of β-cell function. It prevents β-cell dysfunction and diabetes in female ZDF rats on a high-fat diet. It has been shown to block left ventricular remodeling and dysfunction in a rat model of heart failure. Preservation of normoglycemia and normal glucose tolerance in compound PD166793-treated animals is accompanied by preservation of the high serum insulin levels that are a consequence of the insulin resistance present in these animals. It is not reversing insulin resistance these animals. The most striking effect of the compound is on pancreatic insulin content and β-cell volume. |
