What is ISA-2011B?
Biological Activity
ISA-2011B is an inhibitor of PIP5K1α with anticancer activity.
in vitro
The proliferation rate of PC-3 cells after treatment with ISA-2011B at 10, 20, and 50 μM is significantly reduced to 58.77%, 48.65%, and 21.62% of vehicle-treated controls, respectively. It exhibits the highest binding affinity to PIP5K1α, and to MAP/microtubule affinity-regulating kinase 1 and 4 (MARK1 and MARK4) across 460 kinases. It treatment inhibits PIP5K1α expression by 78.6% in PC-3 cells. It leads to a remarkable reduction in AR-V7 and CDK1 in both nucleus and cytoplasm of 22Rv1 cells. It treatment also abolishes AR expression in the nucleus, without depleting the cytoplasmic AR.

in vivo
ISA-2011B significantly inhibits growth of tumor cells in xenograft mice, and is mediated by targeting PIP5K1α-associated PI3K/AKT and the downstream survival, proliferation, and invasion pathways. Overexpression of AR-V7 increases PIP5K1α, promotes rapid growth of PCa in xenograft mice, whereas inhibition of PIP5K1α by its inhibitor. It suppresses the growth and invasiveness of xenograft tumors overexpressing AR-V7.It disrupts protein stabilization of AR-V7 which is dependent on PIP5K1α, leading to suppression of invasive growth of AR-V7-high tumors in xenograft mice.
