bpV(phen) 

bpV(phen), a insulin-mimetic agent, is a potent protein tyrosine phosphatase (PTP) and PTEN inhibitor with IC₅₀s of 38 nM, 343 nM and 920 nM for PTEN, PTP-β and PTP-1B, respectively. bpV(phen) inhibits proliferation of the protozoan parasite Leishmania in vitro. bpV(phen) strongly induces the secretion of a large number of chemokines and pro-inflammatory cytokines, and it activates a Th1-type pathway (IL-12, IFNγ). bpV(phen) can also induce cell apoptosis, and has anti-angiogenic and anti-tumor activity^{[1][2][3][4][5]}.

bpV(phen) (5 μM; 24.5 hours; H9c2 cells) treatment causes a further decrease of cell viability in H/R-injured H9c2 cells^[1].
bpV(phen) (5 μM; 24.5 hours; H9c2 cells) treatment increases the apoptosis of H/R-injured H9c2 cells^[1].
bpV(phen) (5 μM; 24.5 hours; H9c2 cells) treatment significantly promotes the accumulation of cytoplasmic Cytochrome C in H/R-injured H9c2 cells^[1].
After stimulation of bpV(phen), PTEN-induced putative kinase protein 1 (PINK1)/Parkin-mediated mitophagy is inhibited^[1].
bpV(phen) is an insulin-mimetic agent following insulin-receptor tyrosine kinase hyperphosphorylation and activation^[4].
