    In Vitro

    Ricolinostat (ACY-1215) has slight activity against HDAC8 (IC50=0.1 μM), and has minimal activity (IC50>1 μM) against HDAC4, HDAC5, HDAC7, HDAC9, HDAC11, Sirtuin1, and Sirtuin2. The effect of Ricolinostat (ACY-1215) on multiple myeloma (MM) cell viability is determined with MTT assays using MM cell lines. Exposure of MM cell lines for 48 hours results in dose-dependent decreased viability, with IC50 values ranging from 2-8μM. Ricolinostat (ACY-1215) demonstrates significant activity in the MM PS-341-resistant cell line (ANBL-6.BR), demonstrating the ability of Ricolinostat (ACY-1215) to overcome PS-341 resistance[1].

    In Vivo

    Mice treated with Ricolinostat (ACY-1215), PS-341, or Ricolinostat plus PS-341 show a significant delay in tumor growth (P=0.01, P=0.006, and P<0.0001, respectively). Combined treatment with Ricolinostat and PS-341 shows significant suppression of tumor growth and significantly prolonged overall survival (OS) compare with the control group (17 days in the control vs 40 days in the combination-treated group, P<0.0001) and the Ricolinostat (ACY-1215)-treated group (22 days in the PS-341 group vs 40 days in the combination-treated group, P<0.0001). Weight loss in the combination-treated group is between 4% and 12% compare with the same-day control group values during treatment, with complete recovery after the last injection. As is observed in the plasmacytoma model, a significant therapeutic advantage is found by combining Ricolinostat with PS-341 compare with either agent alone[1].

    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.

    Cell Assay
    [1]

    The effect of Ricolinostat with or without PS-341 on the viability of MM cell lines, patient MM cells, and PBMCs is assessed by measuring MTT dye absorbance. PBMCs from healthy donors are isolated and stimulated with 2.5 μg/mL of phytohemagglutinin (PHA) for 48 hours in the presence of increasing concentrations of Ricolinostat (ACY-1215). DNA synthesis is measured by tritiated thymidine uptake. CD4+ T cells are purified from human blood with the Rosette Sep negative-selection kit. Cells are stimulated by CD3/CD28 Dynabeads for 7 days in the presence of compounds. Cell viability is assessed using alamarBlue. MM cells (2-3×104 cells/well) are incubated in 96-well culture plates with medium and different concentrations of Ricolinostat (ACY-1215), PS-341, and/or recombinant IL-6 (10 ng/mL) or IGF-1 (50 ng/mL) for 24 hours at 37°C, and tritiated thymidine incorporation is measured[1].

    Animal Administration
    [1]

    Mice[1]
    To evaluate the in vivo anti-MM activity of Ricolinostat, male SCID mice are inoculated subcutaneously with 5×106 MM.1S cells in 100 μL of serum-free RPMI 1640 medium. When tumors are measurable, mice are treated IP with Ricolinostat 50 mg/kg dissolved in 10% DMSO in 5% dextrose in water consecutively for 5 days a week for 3 weeks; PS-341 0.5 mg/kg dissolved in 0.9% saline solution biweekly (IV) for 3 consecutive weeks; or combination with the same dosing regimen used for the individual agents. The control group receive the carrier alone at the same schedule as the combination group. Tumor size is measured every other day in 2 dimensions using calipers, and tumor volume is calculated with the formula: V=0.5(a×b2) where a is the long diameter of the tumor and b is the short diameter of the tumor. Mice are killed when the tumor reaches 2 cm3 or is ulcerated. Survival and tumor growth are evaluated from the first day of treatment until death.

    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.
