描述 | CUDC-101 is a potent, multi-acting inhibitor against histone deacetylases (HDAC), epidermal growth factor receptor (EGFR), and human epidermal growth factor receptor 2 (HER2) with IC50 values of 4.4, 2.4, and 15.7 nM, respectively. CUDC-101 had weak inhibition on the following proteins: KDR (VEGFR2) (849 nM), Src (11000 nM), Lyn (840 nM), Lck (5910 nM), Abl-1 (2890 nM), FGFR-2 (3430 nM), Flt-3 (1500 nM), and Ret (3200 nM). CUDC-101 exhibited strong anti-proliferative activity in many human cancer cell lines with IC50 value ranging from 0.04 – 0.80 μM[3]. The exposure of CUDC-101 (0.1, 1, or 10 μmol/L) for 5 to 24 hours increased acetylation of histone H3 and H4 in various cancer cell lines at a dose-dependent manner. CUDC-101 at 1 μmol/L also inhibited EGFR and HER2 phosphorylation and the level of antiapoptotic proteins, survivin, and Bcl-xL. By treating HCT-116 colon cancer cells with CUDC-101 (0.1, 1, or 10 μmol/L) for 24 hours, the activities of caspases 3 and 7 were significantly increased. In Hep-G2 liver cancer xenograft model, daily administration of 120 mg/kg CUDC-101 for 9 days significantly induced 30% tumor regression. Similarly, CUDC-101 (120 mg/kg/day) treatment showed significant inhibitory effect on tumor growth in A549 NSCLC cell- and MDA-MB-468 breast cancer cell-implanted mice[4]. | ||
作用机制 | CUDC-101 is a synthesized, multi-targeted inhibitor for HDAC, EGFR, and HER2. The structure of quinazoline is a well-characterized scaffold for the inhibition of EGFR and HER2. By incorporating a hydroxamic acid into the quinazoline pharmacophore with a proper spacer, this compound binds to HDAC to disrupt its enzyme activity[3]. |
