SPHINX31 is a potent and selective SRPK1 inhibitor, with an IC50 of 5.9 nM. SPHINX31 inhibits phosphorylation of serine/arginine-rich splicing factor 1 (SRSF1). SPHINX31 also decreases the mRNA expression of pro-angiogenic VEGF-A165a isoform. SPHINX31 can be used to research neovascular eye disease[1][2][3]. | [in vivo]
SPHINX31 (200 μg/mL; twice daily topical eye drops) protects the retinal endothelial permeability barrier from diabetes-associated loss of integrity[3]. | Animal Model: | Norway Brown rats (intraperitoneally injected with 50 mg/kg Streptozotocin (HY-10219) to induce type I diabetes)[3] | | Dosage: | 200 μg/mL | | Administration: | Twice daily topical eye drops | | Result: | Reduced retinal permeability in the diabetics (7.92 ± 1.65 × 10-4 cms-1) less than before induction of diabetes (8.15 ± 2.33 × 10-4 cms-1), and less than the control group (8.85 ± 1.29 × 10-4 cms-1), while the diabetes group was 12.67 ± 1.09 × 10-4 cms-1. |
