LY333531 hydrochloride competitively and reversibly inhibits PKCβI and PKCβII (IC50 values are 4.7 and 5.9 nM respectively). Selective for PKCβ over other PKC isozymes (IC50 values are 0.052, 0.25, 0.30, 0.36, 0.60 and >100 μM for PKCη, -δ, -γ, -α, -ε and -ζ respectively). LY333531 exhibits ATP dependent competitive inhibition of PKC beta I and is selective for PKC in comparison to other ATP dependent kinases (protein kinase A, calcium calmodulin, caesin kinase, src tyrosine kinase).
|Preparation method||Western blot Aortas and HUVECs were lysed in lysis buffer or membrane and cytosol protein extraction kit and total proteins in the supernatant were extracted to perform Western blot analysis. Equal amounts of proteins were separated through electrophoresis on SDS-PAGE gels and transferred to nitrocellulose membranes (Millipore, MA, USA). After blocked with 5% skim milk, the membranes were incubated with the appropriate primary antibodies respectively against PKC-β (Abcam, CA, USA), and β-actin (Zhong Shan Golden Bridge Biotechnology, Beijing, China) with recommended dilution at 4 °C overnight. The membranes were washed and further incubated with corresponding secondary antibodies [Anti-Rabbit IgG; Anti-mouse IgG (Zhong Shan Golden Bridge Biotechnology, Beijing, China)] with horseradish peroxidase (HRP) conjugation at 37 °C for 60 min. The films were developed using an ECL Plus chemiluminescence reagent kit (Millipore, MA, USA) and visualized using ChemiDocXRS (Bio-Rad Laboratory, CA, USA). Densitometries were analyzed using Quantity One software.|
|Animal models||Male Sprague-Dawley rats diabetes models|
|Formulation||dissolved in citrate buffer (0.1 mol/L, pH 4.5)|
|Administration||oral gavage for 4 weeks|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
