Background:
Ivaltinostat (CG-200745) formic is an orally active, potent pan-HDAC inhibitor 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 of MDM2 and 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 induces apoptosis and has anti-tumour effects[1][2][3].
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].
Ivaltinostat (CG-200745; p.o.; 30 mg/kg/day; for 7 days) formic attenuates oxidative stress, inflammatory cytokines, and adhesion molecules in UUO kidneys[5].
