SPHINX31 is a highly potent, selective, and cell active SRPK1 inhibitor (IC50 value of 6 nM). Treatment with this inhibitor inhibited SRPK1 activity and phosphorylation of serine/arginine splicing factor 1 (SRSF1), resulting in alternative splicing of VEGF-A from pro-angiogenic to antiangiogenic isoforms. This property resulted in potent inhibition of blood vessel growth in models of choroidal angiogenesis in vivo.
