Target

IC50: 35.6 nM (SRPK1), 98 nM (SRPK2)[1]

In Vitro SRPK-IN-1 treatment at 200 nM significantly reduces SR protein phosphorylation at the steady state with or without washout[1]. SRPK-IN-1 potently converts VEGF from pro-angiogenic to anti-angiogenic isoform[1].
In Vivo SRPK-IN-1 blocks angiogenesis in a CNV mouse model through VEGF alternative splicing[1].
