SPHINX is a selective SRPK1 inhibitor with an IC50 value of 0.58 μM. SPHINX effectively reduces Choroidal Neovascularization (CNV) in vivo. SPHINX can be used for the research of (age-related macular degenaration) AMD[1].
SRPIN340 is an ATP-competitive serine-arginine-rich protein kinase (SRPK) inhibitor, with a Ki of 0.89 μM for SRPK1.
LK1/2-IN-3 (compound 3) is a potent and selective CLK1 and CLK2 inhibitor with IC50 values of 1.1, 2.1, 130, 260, 260 nM for CLK1, CLK2, SRPK1, SRPK2, SRPK3, respectively. CLK1/2-IN-3 shows anti-proliferative activity. CLK1/2-IN-3 reduces the levels of endogenous phosphorylated SR proteins and increases the expression of S6K mRNAs[1].
SPHINX31 is a potent and selective inhibitor of serine/arginine-rich protein kinase 1 (SRPK1), with an IC50 of 5.9 nM. SPHINX31 inhibits phosphorylation of serine/arginine-rich splicing factor 1 (SRSF1), which is a SRPK1 substrate. SPHINX31 is a potential topical therapeutic for neovascular eye disease[1].
SRPK-IN-1 is a covalent and irreversible SRPK1/2 inhibitor with IC50s of 35.6 and 98 nM, respectively. Anti-angiogenesis effect[1].
