ACY-1215 is a hydroxamic acid derivative. ACY-1215 is 12-, 10-, and 11-fold less active against HDAC1, HDAC2, and HDAC3 (class I HDACs), respectively. ACY-1215 has minimal activity (IC50 > 1μM) against HDAC4, HDAC5, HDAC7, HDAC9, HDAC11, Sirtuin1, and Sirtuin2, and has slight activity against HDAC8 (IC50 = 0.1μM). The IC50 values for ACY-1215 for T-cell toxicity is 2.5μM. ACY-1215 overcomes tumor cell growth and survival conferred by BMSCs and cytokines in the BM milieu. ACY-1215 in combination with bortezomib induces synergistic anti-MM activity. ACY-1215 induces potent acetylation of α-tubulin at very low doses and triggers acetylation of lysine on histone H3 and histone H4 only at higher doses, confirming its specific inhibitory effect on HDAC6 activity.

Ricolinostat decreases MM cell viability. A panel of MM cell lines was treated with the indicated concentrations of ricolinostat for 72 hours. Cell viability was measured by MTT assay.

31015208
In vivo ACY-1215 in combination with bortezomib triggered more significant anti-MM activity than either agent alone in suppressing tumor growth and prolonging survival in both plasmacytoma model and disseminated MM model without significant adverse effects. ACY-1215 is readily absorbed by tumor tissue. Moreover, the drug does not accumulate in tumor tissue, as evidenced by the parallel decline of acetylated α-tubulin in blood cells and tumor tissue by 24 hours after dose. [1]

Protocol

Kinase Assay:

[1]
- Collapse

HDAC enzymatic assays:

ACY-1215 is dissolved and subsequently diluted in assay buffer [50 mM HEPES, pH 7.4, 100 mM KCl, 0.001% Tween-20, 0.05% BSA, and 20 μM tris(2-carboxyethyl)phosphine] to 6-fold the final concentration. HDAC enzymes are diluted to 1.5-fold of the final concentration in assay buffer and pre-incubated with ACY-1215 for 10 minutes before the addition of the substrate. The amount of FTS (HDAC1, HDAC2, HDAC3, and HDAC6) or MAZ-1675 (HDAC4, HDAC5, HDAC7, HDAC8, and HDAC9) used for each enzyme is equal to the Michaelis constant (Km), as determined by a titration curve. FTS or MAZ-1675 is diluted in assay buffer to 6-fold the final concentration with 0.3μM sequencing grade trypsin. The substrate/trypsin mix is added to the enzyme/compound mix and the plate is shaken for 60 seconds and then placed into a SpectraMax M5 microtiter plate reader. The enzymatic reaction is monitored for release of 7-amino-4-methoxy-coumarin over 30 minutes, after deacetylation of the lysine side chain in the peptide substrate, and the linear rate of the reaction is calculated.

    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 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 × 104cells/well) are incubated in 96-well culture plates with medium and different concentrations of ACY-1215, bortezomib, and/or recombinant IL-6 (10 ng/mL) or insulin-like growth factor-1 (IGF-1; 50 ng/mL) for 24 hours at 37°C, and tritiated thymidine incorporation is measured.
