A-674563

The Uses of A-674563

A-674563 inhibits Akt1, PKA and CDK2 with Ki of 11 nM, 16 nM and 46 nM, respectively.

What are the applications of Application

A-674563 is a selective Akt1, PKA, and CDK2 inhibitor

Biological Activity

a-674563 is a potent and selective akt1 inhibitor with ic50 value of 14 nm. a-67453 also inhibited pka and cdk2 with ic50 value of 16 nm and 46 nm.akt, also known as protein kinase b, is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration.in miapaca-2 cells treated with a-674563 for 48 hour, it slowed the tumor cell proliferation (ec50 = 0.4 μm). in sts cells, phosphorylation of gsk3 and mdm2 was prominently reduced by a-674563 treatment. [1] akt inhibition-induced g2 cells cycle arrest and apoptosis were also observed in a563-treated sts cells. [2]in scid mice carrying established pc-3 tumors, administration of a-674563 at 40 mg/kg per day for 21 days, combined with administration of paclitaxel at 15 mg/kg per day on days 20.24.28, increased the efficacy of paclitaxel compared with paclitaxel monotherapy. [1] a563 also significantly blocked ht1080 xenograft growth in nude mice. [2]
