VO-Ohpic is a potent inhibitor of PTEN (phosphatase and tensin homolog) with IC50 of 35 nM.

BpV(HOpic) is a potent and selective inhibitor of PTEN with an IC50 of 14 nM. Nanocarrier-BpV(HOpic) has neuroprotective activity.

bpV(phen) hydrate 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) hydrate inhibits proliferation of the protozoan parasite Leishmania in vitro. bpV(phen) hydrate 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) hydrate can also induce cell apoptosis, and has anti-angiogenic and anti-tumor activity.
