SCH900776 是一种针对细胞周期检查点激酶 1(Chk1)的药物,具有潜在的放射增敏和化疗增敏活性。它特异性地结合并抑制 Chk1,这可能导致肿瘤细胞绕过 Chk1 依赖的细胞周期在 S 和 G2/M 阶段停滞,以进行 DNA 修复,然后进入有丝分裂;因此,肿瘤细胞可能对电离辐射和烷化化疗药物的 DNA 损伤效应变得敏感。
SCH900776 is an agent targeting cell cycle checkpoint kinase 1 (Chk1) with potential radiosensitization and chemosensitization activities. It specifically binds to and inhibits Chk1, which may result in tumor cells bypassing Chk1-dependent cell cycle arrest in the S and G2/M phases to undergo DNA repair prior to entry into mitosis; tumor cells may thus be sensitized to the DNA-damaging effects of ionizing radiation and alkylating chemotherapeutic agents.
Store lyophilized at -20ºC, keep desiccated. In lyophilized form, the chemical is stable for 36 months. In solution, store at -20ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.
