K34c is a potent and selective α5β1 integrin inhibitor (IC50 = 3.1 nM). K34c inhibits cell survival and migration, inhibits p53-dependent senescence induced by Temozolomide or Ellipticine and promotes apoptosis in U87MG cells. K34c also prevents TGFβ-induced infiltrationin vivoand reduces cell adhesion on fibronectin.
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.
MAO A HSP90-IN-2(compound 4-C)是一种针对HSP90和MAO A的双重抑制剂,显示出分别对这两种酶有0.016 μM和4.58 μM的IC50值。该化合物能够上调HSP70,降低HER2和磷酸化AKT的表达,同时能减少GL26细胞中由IFN-γ诱导的PD-L1表达增加。此外,MAO A HSP90-IN-2能够抑制对Temozolomide敏感或耐药的胶质母细胞瘤(GBM)、结肠癌、白血病和非小细胞肺癌细胞的生长,并可能有助于阻止肿瘤逃避免疫监控。
