产品描述

Targets:Chk1, cdc2 and PKC

IC50:15, 250 and 1000 nM for Chk1, cdc2 and PKC respectively

SB 218078 is a potent inhibitor of checkpoint kinase 1, with the IC50 values of 15, 250 and 1000 nM for Chk1, cdc2 and PKC, respectively.

In Vitro: An in vitro kinase assay found that SB 218078 could potently inhibit the phosphorylation of Chk1, with the IC50 of 15 nM. In Hela cells, SB 218078 could cause complete abrogation of G2 cell cycle arrest induced by topotecan, with the minimum concentration of 2.5 μM [1]. Besides, 15 nM SB 218078 could effectively inhibit NKG2D ligand upregulation induced by aphidicolin in fibroblasts [2]. Furthermore, treated GM02188 cells with 2.5 μM SB 218078 could inhibit the formation of HU-induced 53bp1 foci and prevent recovery from replication fork stalling induced by APH [3].

In Vivo: In Myc-induced lymphomas mouse model, treatment with SB 218078 with the dose of 5 mg/kg could promote a strong increase of γ-H2AX and apoptosis throughout the lymphoma, while having no effect on a healthy spleen [4].

Clinical trial: No data available recently
