BVT948 is a noncompetitive, cell-permeable and novel PTP inhibitor with an IC50 of 0.09-1.7 μM. [1]

Protein-tyrosine phosphatases (PTPs) are involved in the regulation of diverse intracellular signalings. It can promote cell migration in mammalian cells [2], induce MMP-9 expression in MCF-7 breast cancer cells. [3]

BVT948 blocks breast cancer cell invasion via suppression of the expression of MMP-9. Treatment of 0.5, 1 or 5 μM BVT948 for 24 h did not cause any significant changes in MCF-7 cell viability. BVT948 inhibited TPA-induced MMP-9 up-regulation in a dose-dependent manner. Treatment MCF-7 cells with BVT948 blocked the up-regulation of TPA-induced MMP-9 protein expression. BVT948 significantly diminished TPA-induced MMP-9 secretion. BVT948 diminished 50% cell invasion after the TPA-induced. BVT948 inhibits NF-κB activation by suppressing IκBα degradation and the nuclear translocation of NF-κB in TPA-treated MCF-7 cells. The MAPK pathways are not involved in the inhibition of TPA-induced MMP-9 expression by BVT948. [4]
