Description

ATWLPPR Peptide TFA, a heptapeptide, acts as a selective neuropilin-1 inhibitor, inhibits VEGF₁₆₅ binding to NRP-1, used in the research of angiogenesis^[1]. ATWLPPR Peptide TFA has potential in reducing the early retinal damage caused by diabetes^[2].

IC₅₀ & Target

Neuropilin-1^[2]

In Vitro

ATWLPPR Peptide TFA is a selective neuropilin-1 inhibitor, inhibits VEGF₁₆₅ binding to NRP-1 by 82% at 100 μM^[1].

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

In Vivo

ATWLPPR (400 μg/kg, s.c.) preserves vascular integrity and decreases the oxidative stress level, possibly reduces the early retinal damage caused by diabetes^[2].
ATWLPPR prevents the increase of inflammation-associated proteins (GFAP, VEGF and ICAM-1) in the retina^[2].
