Cat. No.: HY-107407 Purity: ≥98.0%
COA Handling Instructions

SB-218078 is a potent, selective, ATP-competitive and cell-permeable checkpoint kinase 1 (Chk1) inhibitor that inhibits Chk1 phosphorylation of cdc25C with an IC50 of 15 nM. SB-218078 is less potently inhibits Cdc2 (IC50 of 250 nM) and PKC (IC50 of 1000 nM). SB-218078 causes apoptosis by DNA damage and cell cycle arrest.

Description

SB-218078 is a potent, selective, ATP-competitive and cell-permeable checkpoint kinase 1 (Chk1) inhibitor that inhibits Chk1 phosphorylation of cdc25C with an IC50 of 15 nM. SB-218078 is less potently inhibits Cdc2 (IC50 of 250 nM) and PKC (IC50 of 1000 nM). SB-218078 causes apoptosis by DNA damage and cell cycle arrest[1][2][3].

In Vitro

SB-218078 (2.5-5 μM; 18 hours; HeLa cells) treatment abrogates G2 cell cycle arrest caused by either γ-irradiation or a topoisomerase I Topotecan inhibition[1].
SB-218078 (500-625 μM; 96 hours; HeLa and HT-29 cells) treatment significantly increases the cytotoxicity of DNA damage [1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Cycle Analysis[1]

Cell Line: HeLa cells
Concentration: 2.5 μM, 5 μM
Incubation Time: 18 hours
Result: Abrogated G2 cell cycle arrest caused by γ-irradiation and topoisomerase I inhibition.

Cell Cytotoxicity Assay[1]

Cell Line: HeLa and HT-29 cells
Concentration: 500 nM, 625 nM
Incubation Time: 96 hours
Result: Enhanced cytotoxicity of DNA damage.
In Vivo

SB-218078 (5 mg/kg; intraperitoneal injection; for 16 hours; C57/Bl6 mice) treatment could promote a strong increase of γ-H2AX and apoptosis throughout the lymphoma, while having no effect on a healthy spleen in Myc-induced lymphomas mouse model[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57/Bl6 mice injected with ARF-/- lymphomas[2]
Dosage: 5 mg/kg
Administration: Intraperitoneal injection; for 16 hours
Result: Promoted a strong increase of γ-H2AX and apoptosis throughout the lymphoma.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
