描述 | Nampt inhibition by (E)-Daporinad (FK866) leads to a significant reduction in NAD+ levels intracellularly, selectively killing multiple myeloma (MM) cells. The cell death induced by (E)-Daporinad is linked to the inhibition of Nampt activity, not its protein expression. MM cells, having higher baseline NAD+ levels compared to normal peripheral blood mononuclear cells (PBMCs), are more susceptible to (E)-Daporinad. Additionally, (E)-Daporinad neutralizes the survival benefits that the bone marrow microenvironment confers on MM cells[1]. (E)-Daporinad (FK866) inhibits the increase in intracellular calcium ([Ca2+].i) that is typically induced by various mitogens and decreases the calcium content of thapsigargin-responsive calcium stores in Jurkat cells and activated peripheral blood lymphocytes (PBLs). However, it does not affect the calcium content in Bcl2-overexpressing Jurkat cells[2]. The inhibition of NAMPT by (E)-Daporinad (FK866), or SIRT by nicotinamide, reduces cell proliferation and induces cell death in 293T cells. This effect involves the p53 acetylation pathway, highlighting a critical regulatory mechanism in cell survival and death[3]. |
