生物活性
Diprotin A (Ile-Pro-Ile) 是二肽基肽酶 IV (DPP-IV) 的抑制剂。靶点
IC50: DPP-IV
体外研究
Diprotin A (100 μM; 30 minutes after CXCR4-blocker or Src-inhibitor treatment) induces the phosphorylation of Src [Tyr 416] and VE-cadherin [Tyr731] in hECs in both normoxia and H/R conditions in human endothelial cells and disrupts endothelial cell-to-cell junctions, which are attenuated by CXCR4 (receptor of SDF-1α)-blocker or Src-inhibitor.
Western Blot Analysis
| Cell Line: | Human endothelial cells [1] |
| Concentration: | 100 μM |
| Incubation Time: | 30 minutes after CXCR4-blocker or Src-inhibitor treatment |
| Result: | Induced the phosphorylation of Src [Tyr 416] and VE-cadherin [Tyr731] in hECs. |
体内研究
Diprotin A (intraperitoneal injection; 70 μg/kg; twice daily; 7 days) increases the phosphorylation of Src and VE-cadherin and aggravates vascular leakage in the retinas. Collectively, Diprotin A induces vascular leakage by augmenting the SDF-1α/CXCR4/Src/VE-cadherin signaling pathway.
| Animal Model: | Streptozotocin-induced diabetic retinopathy model in wild-type C57/BL6 mice |
| Dosage: | 70 μg/kg |
| Administration: | Intraperitoneal injection; twice daily; 7 days |
| Result: | Induced vascular leakage by augmenting the SDF-1α/CXCR4/Src/VE-cadherin signaling pathway. |
