CUDC-101 is a potent multitargeted HDAC, EGFR and HER2 inhibitor with IC50 of 4.4, 2.4, and 15.7 nM, respectively.
IC50 Value: 4.4 nM(HDAC); 2.4 nM(EGFR); 15.7 nM(HER2)
Target: EGFR; HER2; HDAC
in vitro: CUDC-101 inhibits the erlotinib-resistant EGFR mutant T790M although its effects are incomplete with an Amax of ~60% of peak enzyme activity after inhibition. CUDC-101 treatment increases the acetylation of histone H3 and H4, as well as the acetylation of non-histone substrates of HDAC such as p53 and α-tubulin, in a dose-dependant manner in various cancer cell lines. CUDC-101 also suppresses HER3 expression, Met amplification, and AKT reactivation in tumor cells.
in vivo: Administration of CUDC-101 at 120 mg/kg/day induces tumor regression in the Hep-G2 liver cancer model, which is more efficacious than that of erlotinib at its maximum tolerated dose (25 mg/kg/day) and vorinostat at an equimolar concentration dose (72 mg/kg/day). CUDC-101 inhibits the growth of erlotinib-sensitive H358 NSCLC xenografts in a dose-dependent manner. CUDC-101 also shows potent inhibition of tumor growth in the erlotinib-resistant A549 NSCLC xenograft model. CUDC-101 produces significant tumor regression in the lapatinib-resistant, HER2-negative, EGFR-overexpressing MDA-MB-468 breast cancer model and the EGFR-overexpressing CAL-27 head and neck squamous cell carcinoma (HNSCC) model. Additionally, CUDC-101 inhibits tumor growth in the K-ras mutant HCT116 colorectal and EGFR/HER2 (neu)-expressing HPAC pancreatic cancer models.
