生物活性

Romidepsin (FK 228) is a Histone deacetylase (HDAC) inhibitor with anti-tumor activities. Romidepsin (FK 228) inhibits HDAC1, HDAC2, HDAC4, and HDAC6 with IC50s 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 and apoptosis[2].

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].
