Niraparib (MK-4827) 是一种 PARP 抑制剂，可以抑制 PARP1 和 PARP2 (IC50=3.8 2.1 nM)，具有选择性。Niraparib 具有抗肿瘤活性，可以抑制 DNA 损伤修复、诱导细胞凋亡。

Niraparib hydrochloride (MK-4827 hydrochloride) 是一种具有口服活性的PARP1和PARP2抑制剂，IC50值分别为 3.8 nM 和 2.1 nM。它抑制 DNA 损伤修复，诱导凋亡并具有抗肿瘤活性。

MK-4827 Racemate (Niraparib Racemate) 是一种选择性 PARP1 和 PARP2 抑制剂，IC50 分别为 3.8 nM 和 2.1 nM，对 PARP3、V-PARP 和 Tank1 的选择性超过 330 倍。

ExcisaninA may be a potent inhibitor of AKT signaling pathway in tumor cells, it can inhibit invasion by suppressing MMP-2 and MMP-9 expression, it may be a potential anti-metastatic chemotherapeutic agent for the treatment of breast cancer. Excisanin A shows comparable inhibitory effects on the LPS-induced production of NO and PGE2, and activation of NF-kappaB without affecting cell viability.Excisanin A induces apoptosis in colon cancer cell line SW620 as determined by Annexin V staining, the cleavage of caspase-3 and the proteolytic degradation of poly (ADP-ribose) polymerase (PARP).
