|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. CUDC-907 induces cell cycle arrest and apoptosis in breast cancer cells. 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. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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.
