Protein Kinase C Inhibitors

Hyperglycemia can activate PKC, which in turn increases oxidative stress. Inhibitors of PKC can restore vascular function and also increase mRNA expression of eNOS in aortic endothelial cells (143). Recently, an inhibitor of PKC, LY333531, has been developed; it normalizes retinal blood flow and glomerular filtration rate in parallel with inhibition of PKC activity (169). LY333531 is discussed in detail in Chapter 2. Beckman and colleagues (170) found that this inhibitor of PKCP attenuated the impairment of endothelial-dependent vasodilation on healthy human subjects exposed to hyperglycemia.
