|Description||CUDC-907 is a dual PI3K and HDAC inhibitor for PI3Kα and HDAC1/2/3/10 with IC50 of 19 nM and 1.7 nM/5 nM/1.8 nM/2.8 nM, respectively. Phase 1.|
CUDC-907 inhibits other PI3K isoforms such as PI3Kβ, PI3Kγ, PI3Kδ, PI3KɑH1047R and PI3KɑE545K with IC50 of 54 nM, 311 nM, 39 nM, 73 nM and 62 nM, respectively. Moreover, CUDC-907 also prevents HDAC subtypes HDAC8, HDAC6 and HDAC11 with IC50 of 191 nM, 27 nM and 5.4 nM, respectively.  In addition, CUDC-907 suppresses other types of HDAC enzymatic activity with lower potency. CUDC-907 inhibits the growth of a series of B cell lymphoma such as Granta 519, DOHH2, RL, Pfeiffer, SuDHL4, Daudi and Raji with IC50 of 7 nM, 1 nM, 2 nM, 4 nM, 3 nM, 15 nM and 9 nM, respectively. CUDC-907 also blocks the proliferation of Myeloma including RPMI8226, OPM-2 and ARH77 with IC50 of 2 nM, 1 nM and 5 nM, respectively. CUDC-907 displays greater anti-tumor activity in multiple myeloma and B cell lymphoma. 
|In vivo||CUDC-907 has a long half-life in murine tumors. CUDC-907 induces apoptosis and inhibits cancer cell proliferation in xenograft tumors.  In efficacy studies in NHL and MM models, CUDC-907 is more efficacious than either a single-agent PI3K or HDAC inhibitor reference compound or a combination of the two agents given at maximally tolerated doses (MTD). Furthermore, CUDC-907 is more efficacious than the PI3Kδ-selective inhibitor CAL-101 when dosed at MTD doses. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
