General description

LY-333531 hydrochloride is also known as ruboxistaurin.

Application

LY-333531 hydrochloride/ruboxistaurin has been used as a PKCB blocker to compare phosphopeptides derived from stimulated wild-type cells to phosphopeptides derived from either PKCB knockout cells or wild-type cells.

Biochem/physiol Actions

LY333531 is a potent inhibitor of protein kinase Cβ (PKCβ; 4.7 and 5.9 nM IC50 values for PKCβ1 and PKCβ2, respectively). PKCβ isoforms are overexpressed in states of oxidative stress, especially in association with diabetes. In diabetic rats, LY333531 improves blood flow and leukocyte entrapment in the retina, and protects against myocardial hypertrophy and cardiac dysfunction.
