Ibulocydine is a potent CDK inhibitor. Ibulocydine has high activity against Cdk7/cyclin H/Mat1 and Cdk9/cyclin T. Ibulocydine inhibited the growth of HCC cells more effectively than other Cdk inhibitors, including olomoucine and roscovitine, whereas ibulocydine as well as the other Cdk inhibitors and BMK-Y101 minimally influenced the growth of normal hepatocyte cells. Ibulocydine induced apoptosis in HCC cells, most likely by inhibiting Cdk7 and Cdk9. In vitro treatment of HCC cells with ibulocydine rapidly blocked phosphorylation of the carboxyl-terminal domain (CTD) of the large subunit of RNA polymerase II, a process mediated by Cdk7/9. Anti-apoptotic gene products such as Mcl-1, survivin, and X-linked IAP (XIAP) are crucial for the survival of many cell types, including HCC. Following the inhibition of RNA polymerase II phosphorylation, ibulocydine caused rapid down-regulation of Mcl-1, survivin, and XIAP, thus inducing apoptosis. Furthermore, ibulocydine effectively ind......

ADMA-D6 is intended for use as an internal standard for the quantification of NG,NG-dimethyl-L-arginine by GC- or LC-MS. ADMA (T7682) is an endogenous inhibitor of nitric oxide synthase (NOS). It is formed from arginine by protein arginine methyltransferases (PRMTs)and degraded by dimethylarginine dimethylaminohydrolases (DDAHs)and alanine-glyoxylate aminotransferase 2 (AGXT2). ADMA (T7682)levels are increased concomitant with an increase in blood pressure in Dahl salt-sensitive rats fed a high-salt diet. ADMA (T7682)levels are increased in the plasma in a variety of endothelial dysfunction-related diseases,including hypertension,congestive heart failure,and end-stage renal disease.
