GNE-783 是一款高选择性 CHK1 抑制剂,可有效增强吉西他滨的抗肿瘤效果。GNE-783在 DNA 损伤发生后,通过使 S 期与 G2 期细胞周期检查点失活,从而提升抗代谢类 DNA 损伤药物的治疗作用。GNE-783 对不同肿瘤的化疗增敏具有选择性,例如仅在黑色素瘤细胞系中能增强替莫唑胺的抗肿瘤活性。
PARP1-IN-10 (compound 12c) is a highly potent and non-cytotoxic PARP1 inhibitor, displaying an in vitro IC50 value of 50.62 nM. This compound effectively induces cell cycle arrest at the G2/M phase and apoptosis, while also significantly augmenting the cytotoxic effects of temozolomide (TMZ) [1].
NU1085 is a potent poly(ADP-ribose) polymerase (PARP) inhibitors have been developed that potentiate the cytotoxicity of ionizing radiation and anticancer drugs. The biological effects of NU1085 [Ki = 6 nM], in combination with temozolomide (TM) or topotecan (TP) have been studied in 12 human tumor cell lines (lung, colon, ovary, and breast cancer). Cells were treated with increasing concentrations of TM or TP +/- NU1085 (10 microM) for 72 h.
