Romidepsin (FK 228) 是具有抗肿瘤活性的组蛋白去乙酰化酶 (HDAC) 抑制剂,抑制 HDAC1,HDAC2,HDAC4 和 HDAC6,IC50值分别为 36 nM,47 nM,510 nM 和 1.4 μM。Romidepsin (FK 228) 由紫色杆菌产生,诱导 G2/M 细胞周期阻滞和凋亡 (apoptosis)。
生物活性 | Romidepsin (FK 228) is aHistone deacetylase (HDAC)inhibitor with anti-tumor activities. Romidepsin (FK 228) inhibitsHDAC1,HDAC2,HDAC4, andHDAC6withIC50s of 36 nM, 47 nM, 510 nM and 1.4 μM, respectively[1]. Romidepsin (FK 228) is produced by Chromobacterium violaceum, induces cell G2/M phase arrest andapoptosis[2]. |
IC50& Target[1] | HDAC1 36 nM (IC50) | HDAC2 47 nM (IC50) | HDAC4 510 nM (IC50) | HDAC6 14000 nM (IC50) |

体外研究 (In Vitro) | Romidepsin (0-72 hours; 0-80 nM) inhibits proliferation of HCC cells in dose-dependent manner[2].Romidepsin (0-48 hours; 0-60 nM) leads to a time- and dose-dependent induction of cell cycle arrest in the G2/M phase in HCC cells[2].Romidepsin (0-48 hours; 0-60 nM) promotesapoptosis in HCC cells, increases c-caspase-3, c-caspase-9, and c-PARP protein expression[2].

体内研究 (In Vivo) | Romidepsin (intraperitoneal injection; 0.5 and 1 mg/kg; every 3 day; 21 days) inhibited the tumor growth, reveals a higher expression of p-cdc25C, ki67, c-caspase-3 and c-PARP, and a lower expression of Ki-67 in Romidepsin treated tumors[2].
Animal Model: | Nude mice with Huh7 cells[2] | Dosage: | 0.5 and 1 mg/kg | Administration: | Intraperitoneal injection; 0.5 and 1 mg/kg; every 3 day; 21 days | Result: | Suppressed tumor growth in mouse xenograft models. |
