    In Vitro

    CUDC-101 inhibits both class I and class II HDACs, but not class III, Sir-type HDACs. CUDC-101 displays broad antiproliferative activity in many human cancer cell types. CUDC-101 is a potent and selective HDAC, EGFR, and HER2 inhibitor with only weak inhibition of the following protein kinases (IC50): 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)[1].
    CUDC-101 (300 nM) inhibits both the full length AR (flAR) and the AR variant AR-V7[2].
    CUDC-101 is the most active agent in all three ATC cell lines screened for inhibitors of EGFR and HDACs, with half-maximal inhibitory concentration (IC50) at 0.15 μM for 8505c, and 1.66 μM for both C-643 and SW-1736 cells. CUDC-101 inhibits cancer cell migration and modulates epithelial-mesenchymal transition marker expression in ATC cells. CUDC-101 also inhibits HDAC and MAPK pathway, induces p21, and decreases survivin and XIAP expression in ATC cells[3].
    CUDC-101 (1 μM) increases the acetylation of p53 and α-tubulin, nonhistone substrates of HDAC, in treated cancer cells. CUDC-101 modulates RTK activity and expression and exhibits immediate and stable inhibition of RTK and downstream Akt signaling[4].

    In Vivo

    CUDC-101 (120 mg/kg, iv, daily) induces tumor regression in the Hep-G2 liver cancer model and is more efficacious than erlotinib at its maximum tolerated dose (MTD). In the erlotinib-resistant A549 NSCLC xenograft model, CUDC-101 (120 mg/kg) shows potent inhibition of tumor growth. In the erlotinib-sensitive H358 NSCLC models, CUDC-101 (15, 30, 60 mg/kg, i.v.) inhibits tumor growth in a dose-dependent manner. CUDC-101 (120 mg/kg) causes 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. CUDC-101 (120 mg/kg) also inhibits tumor growth in the K-ras mutant HCT116 colorectal and EGFR/HER2 (neu)-expressing HPAC pancreatic cancer models[1].
    In an in vivo mouse model of metastatic ATC, CUDC-101 inhibits tumor growth and metastases, and significantly prolongs survival[3].
    CUDC-101 (120 mg/kg) is effective against a broad range of tumor types in xenograft models[4].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

    Kinase Assay
    [1]

    The activities of Class I and II HDACs are assessed using the Biomol Color de Lys system. Briefly, HeLa cell nuclear extracts are used as a source of HDACs. Different concentrations of drugs are added to HeLa cell nuclear extracts in the presence of a colorimetric artificial substrate. Developer is added at the end of the assay and enzyme activity is measured in the Wallac Victor II 1420 microplate reader at 405 nM.

    Cell Assay
    [1]

    Cancer cell lines are plated at 5000 to 10 000 cells per well in 96-well flat-bottomed plates with varying concentrations of compounds. The cells are incubated with compounds for 72 h in the presence of 0.5% of fetal bovine serum. Growth inhibition is assessed by an adenosine triphosphate (ATP) content assay using the Perkin-Elmer ATPlite kit.

    Animal Administration
    [1]

    Four- to six-week-old female athymic mice (nude nu/nu CD-1) are inoculated subcutaneously into the right hind flank region with 1 to 5×106 cells in a medium suspension of 100−200 μL. For orthotopic implantation of breast cancer cells, a cell suspension in 100 μL of medium is injected directly into the mammary fat pads through a 27G needle. Different doses of CUDC-101, standard anticancer agents and vehicle are administered orally, intraperitoneally, or via tail vein injection as indicated.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
