|Description||Plinabulin (NPI-2358) is a vascular disrupting agent (VDA) against tubulin-depolymerizing with IC50 of 9.8~18 nM in tumor cells. Phase 1/2.|
|Features||Synthetic analog of NPI-2350 and greater potentcy than NPI-2350.|
NPI-2358 binds to the colchicine-binding site of tubulin and has potent inhibitory to human tumor cell lines which have overexpressed Pgp or reduced nuclear Topo II catalytic activity, with IC50 from 9.8 to 18 nM. NPI-2358 is able to rapidly induce tubulin depolymerization in HUVECs and monolayer permeability even at 20 nM.  NPI-2358 induces cell death in MM cells with IC50 of 8-10 nM, which due to trigger early mitotic arrest in MM cells. NPI-2358 also inhibits tubule formation and migration of endothelial as well as MM cells, which leads to disrupt tumor vasculature. NPI-2358 could induces cell death in patient MM (CD138+) cells without effecting viability of normal mononuclear cells. Blockade of JNK abrogates NPI-2358-induced mitotic arrest or MM cell death. 
|In vivo||NPI-2358 (7.5 mg/kg) inhibits tumor growth in human plasmacytoma mouse xenograft models at well-tolerated doses.  NPI-2358 induces a time- and dose-dependent decrease in tumour perfusion. NPI-2358 is more sensitive to the KHT sarcoma than the C3H tumour, while radiation response could enhance the antitumor activity in both models. |

* 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.

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.
