Description

Diprotin A (Ile-Pro-Ile) is an inhibitor of dipeptidyl peptidase IV (DPP-IV)[1].

IC50 & Target

DPP-4

 

In Vitro

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[1].

Western Blot Analysis[1]

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.
In Vivo

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[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Streptozotocin-induced diabetic retinopathy model in wild-type C57/BL6 mice[1]
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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
