brca-1-in-1

BRCA1-IN-1 is a novel small-molecule-like inhibitor of BRCA1 (IC50: 0.53 μM; Ki: 0.71 μM).

BRCA1-IN-2 是一种可穿过细胞膜的 BRCA1 蛋白-蛋白相互作用（PPI）抑制剂，具有抗肿瘤活性，通过破坏 BRCA1 (BRCT)2 与蛋白质的相互作用来发挥作用。

PARP1-IN-27 (Compound 9B)，作为PARP1和PARP2的有效抑制剂，在SUM149PT细胞中的IC50分别达到2.53 nM和6.45 nM。此外，PARP1-IN-27对BRCA突变癌细胞系SUM149PT、HCC1937和Capan-1的增殖抑制效果显著，相应的IC50值为0.62、1.91和4.26 μM。该化合物能够加剧DNA双链断裂，促进ROS生成，并在G2 M期阻滞细胞周期，最终在SUM149PT细胞中触发细胞凋亡(apoptosis)。

USP1-IN-11 (compound 38-P2) 是一种选择性、可逆和非竞争性的USP1(Ubiquitin-specific protease1)抑制剂。它通过激活DDR (DNA damage repair) 通路来诱导细胞周期停滞与细胞凋亡 (Apoptosis)，从而抑制细胞存活。USP1-IN-11 可提高Olaparib耐药细胞的敏感性，且在BRCA功能正常的癌细胞中与Andrographolide具有协同作用。在MDA-MB-436异种移植模型中，该化合物展示出显著的剂量依赖性抗肿瘤效果。

PARP EZH2-IN-1 is a novel compound that functions as a dual inhibitor for both PARP (IC50 6.87 nM) and EZH2 (IC50 36.51 nM), showing promising potential for the treatment of triple-negative breast cancer with wild-type BRCA.

JPI 547, also known as NOV 1402, is an oral inhibitor of PARP 1 2 and Tankyrase 1 2. JPI-547 demonstrated anti-tumor activity in BRCA-deficient xenograft models as a single-agent and in combination with chemotherapy and immune checkpoint inhibitors.

SC10914 is a highly potent PARP inhibitor (PARP1 IC50 = 7.87 nM) with potent anti-proliferative activity against human BRCA deficient tumor cells (MDA-MB-436, BRCA1 deficient, IC50 = 4.03 nM, Capan-1 BRCA2 deficient, IC50 = 11.66 nM) and PTEN deficient tumor cells (HGC-27,PTEN deficient, IC50 = 0.35 μM). SC10914 showed potent anti-tumor activity in BRCA1 2 mutant tumor models and better pharmacokinetics profile has the potential to be selected as the clinical candidate for the treatment of treatment of BRCA1 2 deficient cancers.

VEGFR PARP-IN-1 (Compound 14b) 是一款针对VEGFR和PARP两个靶点的双重抑制剂，其对VEGFR和PARP的IC50值分别为191 nM和60.9 nM。该化合物能够抑制DNA损伤修复机制，诱导apoptosis，并使细胞在G2 M期阻滞。此外，VEGFR PARP-IN-1对BRCA野生型乳腺癌细胞表现出较强的抗增殖效果，尤其是在MDA-MB-231和MCF-7细胞系上，其IC50值分别为4.1 μM和3.5 μM，是潜在的抗肿瘤和抗转移药物。
