产品介绍

SU9516是在肿瘤细胞中表现出抗增殖和促凋亡特性的3-取代的吲哚满酮化合物。SU9516显示出作为CDK的选择性强效ATP竞争性抑制剂的活性。它还对PKC,p38,PDGFRβ或EGFR的活性无明显影响(IC | 50 |> 10μM)。SU9516通过与Cdk2结合并阻止pRb的磷酸化及其从E2F的解离,对生长因子刺激的结肠癌细胞的增殖具有抑制作用。SU9516是Cdc2,Cdk2和Cdk4的抑制剂。

SU9516 is a 3-substituted indolinone compound displaying anti-proliferative and proapoptotic properties in tumor cells. SU9516 displays activity as a selectively potent ATP-competitive inhibitor of CDKs. It also shows no significant effect (IC|50|>10 μM) on the activities of PKC, p38, PDGFRβ, or EGFR. SU9516 has an Inhibitory effect on proliferation of growth-factor stimulated colon carcinoma cells by binding to Cdk2 and preventing the phosphorylation of pRb and its dissociation from E2F. SU9516 is an inhibitor of Cdc2, Cdk2 and Cdk4.

生物活性评价 The sulfonamide class of antibacterial compounds are primarily bacteriostatic agents and have a broad spectrum of activity against both Gram-positive and Gram-negative species of bacteria (reviewed in ).
评价 SU9516 is a potent inhibitor of several cyclin-dependent kinases (CDKs) with reported selectivity for CDK2 . Later analysis of SU9516's selectivity profile indicates a similar level of potency as an inhibitor of CDK5/p25 compared to CDK2 . Inhibition of CDK5 was confirmed in a cellular assay measuring dephosphorylation of pFAK(S732). SU9516 also arrests cells at the G2/M phase in cells lacking CDK2, in which case it must be causing the cell cycle arrest via inhibition of CDK1 .
