Ivaltinostat (CG-200745) formic 是一种口服有效的泛HDAC抑制剂,具有异羟肟酸部分,可在催化袋底部结合锌。Ivaltinostat formic 抑制组蛋白 H3 和微管蛋白的脱乙酰作用。Ivaltinostat formic 诱导p53的积累,促进 p53 依赖性反式激活,并增强 MDM2 和 p21 (Waf1/Cip1) 蛋白的表达。Ivaltinostat formic 可增强 Gemcitabine 耐药细胞对 Gemcitabine (HY-16138) 和 5-Fluorouracil (5-FU; HY-90006) 的敏感性。Ivaltinostat formic 诱导凋亡并具有抗肿瘤作用。
生物活性 | Ivaltinostat (CG-200745) formic is an orally active, potent pan-HDACinhibitor which has the hydroxamic acid moiety to bind zinc at the bottom of catalytic pocket. Ivaltinostat formic inhibits deacetylation of histone H3 and tubulin. Ivaltinostat formic induces the accumulation of p53, promotes p53-dependent transactivation, and enhances the expression ofMDM2and p21 (Waf1/Cip1) proteins. Ivaltinostat formic enhances the sensitivity of Gemcitabine-resistant cells to Gemcitabine (HY-16138) and 5-Fluorouracil (5-FU; HY-90006). Ivaltinostat formic inducesapoptosisand has anti-tumour effects[1][2][3]. |

体外研究 (In Vitro) | Ivaltinostat (CG-200745; 0.01-100 μM; 48 hours) formic inhibits growth of prostate cancer cells (LNCaP, DU145 and PC3 cells). Ivaltinostat (1, 10 μM; 24, 48 hours) formic increases sub-G1 population, and activates caspase-9, -3 and -8[2]. Ivaltinostat (0.001-100 μM; for 72 hours) inhibits proliferation of cholangiocarcinoma cells (IC50s of 0.63, 0.93, and 1.80 μM for SNU-1196, SNU-1196/GR, SNU-308 cells, respectively)[3]. Ivaltinostat (0-10 μM; 48 hours) formic reduces the Calu6 cells proliferation to 40% of untreated cells[4]. Ivaltinostat (3 μM; 1-24 hours) formic significantly increases Calu6 cells proportion in G2/M phase (69%)[4]. Ivaltinostat (0-10 μM; 1-24 hours) formic treatment with low concentration significantly increases the acetylation of histone H3 and H4 in Calu6 cells at various sites in a time-dependent manner up to 24 hours after treatment[4].
