DIPROTIN A Chemical Properties,Usage,Production

Uses

Ile-Pro-Ile has been used as a supplement for blood collection for hormone measurement and used in Islets cell culture to stabilize glucagon-like peptide-1 (GLP-1). It has also been used to inhibit the breakdown of gonadotropin-inhibitory hormone (GnIH) following serum collection.

Uses

As New dipeptidyl peptidase IV inhibitors (Diprotin A) and their uses as anti-cancer agents

Definition

ChEBI: (2S,3S)-2-[[[(2S)-1-[(2S,3S)-2-amino-3-methyl-1-oxopentyl]-2-pyrrolidinyl]-oxomethyl]amino]-3-methylpentanoic acid is a peptide.

Biochem/physiol Actions

Inhibitor of dipeptidyl peptidase IV. Inhibits entry of HIV-1 or HIV-2 into T lymphoblastoid and monocytoid cell lines.

in vivo

Diprotin A (intraperitoneal injection; 70μg/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].

Animal Model:	Streptozotocin-induced diabetic retinopathy model in wild-type C57/BL6 mice^[1]
Dosage:	70μg/kg
Administration:	Intraperitoneal injection; twice daily; 7 days
Result:	Induced vascular leakage by augmenting the SDF-1α/CXCR4/Src/VE-cadherin signaling pathway.

IC 50
