Cat. #151711

Sub-type: Inhibitor

Application: Lomeguatrib (20 mg/kg/day for 5 days) combined with Temozolomide (100 mg/kg/day for 5 days) produces a substantial tumour growth delay: median tumour quintupling time is increased by 22 days without any significant increase in toxicity, while neither of the two drugs administrated along show any antitumor activity. Lomeguatrib inactivates ATase and enhances the anti-tumour effect of Temozolomide in A375M human melanoma xenografts model. Lomeguatrib, at a single dose of 20 mg/kg i.p., produces...

Cat. #151712

Sub-type: Inhibitor

Application: BS-181 is stable in vivo with a plasma elimination half-life in mice of 405 minutes after i.p. administration of 10 mg/kg. BS-181 inhibits the growth of MCF-7 xenografts in the nude mice model in a dose-dependent manner, with 25% and 50% reduction in tumor growth after 2 weeks of treatment at 10 mg/kg/day and 20 mg/kg/day, respectively without apparent toxicity. BS-181 is a small molecule inhibitor of CDK7 in a cell-free environment, which displays more potential activity than roscovitine with IC 50 of 510 nM. Among the CDKs and other 69 kinases from many different classes, BS-181 shows high inhibitory selectivity for CDK7, inhibits CDK2 at concentrations lower than 1 ÎźM which being inhibited 35-fold less potently (IC50 with 880 nM) than CDK7, shows slight inhibition for CDK1, CDK4, CDK5, CDK6 and CDK9 with IC50 values higher than 3.0 ÎźM, and only shows inhibition for several kinases from other classes at high concentrations (>10 ÎźM). BS-181 promotes cell cycle arrest and inhibits the cancer cell growth of a range of tumor types, including breast, lung, prostate and colorectal cancer with IC50 in the range of 11.5-37 ÎźM. In MCF-7 cells, BS-181 inhibits the phosphorylation of the CDK7 substrate RNA polymerase II COOH-terminal domain (CTD), and promotes cell cycle arrest and apoptosis to inhibit the growth of cancer cell lines.

Cat. #151833

Sub-type: Inhibitor

Application: CCT241533 blocked CHK2 activity in human tumor cell lines in response to DNA damage, as shown by inhibition of CHK2 autophosphorylation at S516, band shift mobility changes, and HDMX degradation. CCT241533 did not potentiate the cytotoxicity of a selection of genotoxic agents in several cell lines. However, this compound significantly potentiates the cytotoxicity of two structurally distinct PARP inhibitors. Clear induction of the pS516 CHK2 signal was seen with a PARP inhibitor alone, and th...

Cat. #151834

Sub-type: Antitumoral

Application: Antitumor activity observed in HCT 116 (GI50 = 40 nM) and HT 29 (GI50 = 380 nM), and in breast cancer cell lines. Potent inhibitory effect in NCI 60 cells (GI50 =16 nM and LC50 = 2.24 ÂľM).
