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. ISA-2011B exhibits the highest binding affinity to PIP5K1α, and to MAP/microtubule affinity-regulating kinase 1 and 4 (MARK1 and MARK4) across 460 kinases. ISA-2011B treatment inhibits PIP5K1α expression by 78.6% in PC-3 cells[1]. ISA-2011B leads to a remarkable reduction in AR-V7 and CDK1 in both nucleus and cytoplasm of 22Rv1 cells. ISA-2011B treatment also abolishes AR expression in the nucleus, without depleting the cytoplasmic AR[2].

Protocolo
Cells are grown in phenol red-free RPMI-1640 medium 24 hours and then are treated with drugs alone or in combination for 24 hours or 48 hours. MDV3100 at 5 μM or ISA-2011B at 20 μM or 50 μM final concentrations or solvent DMSO 1% is used. For treatment of 22Rv1 cells with MG132, a proteasome inhibitor, cells are treated with MG132 at 1 μM. For combination treatment of MG132 and ISA-2011B, cells are pre-treated with MG132 for 30 min at 1 μM prior to treatment of ISA-2011B[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice: BALB/c nude mice aged 8 to 12 wk are used in the experiments. Tumor cells are implanted into the mice. Tumor xenografts are treated with vehicle (control), RP-56976 (10 mg/kg), ISA-2011B (40 mg/kg), and RP-56976 (10 mg/kg) in combination with ISA-2011B (40 mg/kg) every second day[1].
