Daporinad

Daporinad, also known as APO-866 and FK866, is a small molecule with potential antineoplastic and antiangiogenic activities. NMPRTase inhibitor APO866 binds to and inhibits nicotinamide phosphoribosyltransferase (NMPRTase), inhibiting the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from niacinamide (vitamin B3), which may deplete energy reserves in metabolically active tumor cells and induce tumor cell apoptosis. In addition, this agent may inhibit tumor cell prioduction of vascular endothelial growth factor (VEGF), resulting in the inhibition of tumor angiogenesis.

How to use

In Vitro:

Nampt inhibition with (E)-Daporinad (FK866) induces significant NAD+ intracellular reduction and selectively kills MM cells. (E)-Daporinad (FK866)-induced cell death is associated with inhibition of Nampt activity, rather than protein expression, and higher NAD+ baseline levels in MM cells than normal PBMCs confer (E)-Daporinad (FK866) sensitivity. (E)-Daporinad (FK866) abrogates the survival advantage conferred by the bone marrow microenvironment[1]. (E)-Daporinad (FK866) prevents the [Ca2+]i increase induced by different mitogens and reduces the Ca2+ content of TG-responsive Ca2+ stores in Jurkat and in activated PBLs. (E)-Daporinad (FK866) reduces the Ca2+ content of TG-responsive Ca2+ stores in Jurkat cells but not in Bcl2-Jurkat cells. Inhibition of NAMPT by (E)-Daporinad (FK866), or inhibition of SIRT by nicotinamide decreases proliferation and triggered death of 293T cells involving the p53 acetylation pathway.

In Vivo:

(E)-Daporinad (FK866) (30 mg/kg, i.p.) decreases the tumor burden in CB17-SCID mice, and the tumor tissue demonstrates a significant decrease in ERK phosphorylation and proteolytic cleavage of LC3.
