Tie Activator

Razuprotafib (AKB-9778) is a potent and selective inhibitor of the catalytic activity of VE-PTP (vascular endothelial protein tyrosine phosphatase) with an IC₅₀of 17 pM. Razuprotafib promotes TIE2 activation, enhances ANG1-induced TIE2 activation, and stimulates phosphorylation of signaling molecules in the TIE2 pathway, including AKT, eNOS, and ERK. Razuprotafib inhibits the structurally related phosphatase PTP1B with an IC₅₀ of 780 nM. Razuprotafib shows excellent selectivity for VE-PTP versus a variety of phosphatases, with the exception of HPTPη (IC₅₀=36 pM) and HPTPγ (100 pM).

Vasculotide is a blood-brain barrier (BBB)-penetrant Tie2 agonist. Vasculotide binds to a unique domain of Tie2, induces receptor clustering to drive phosphorylation, activates downstream PI3K/Akt and eNOS pathways, enhances inter-endothelial cell junctions (such as VE-cadherin and claudin-5), and inhibits inflammatory adhesion molecules, ultimately stabilizing the vascular endothelial barrier and reducing its permeability. Vasculotide alleviates pulmonary microvascular leakage and microcirculatory dysfunction caused by cardiopulmonary bypass, acts as an adjuvant radioprotective agent to reduce acute radiation dermatitis, and promotes BBB recovery after focused ultrasound (FUS). Combination of Vasculotide with antibiotics reduces lung injury.

Gersizangitide (AXT107) is an anti-angiogenic peptide consisting of 20 amino acids, derived from collagen IV. Gersizangitide is an inhibitor of VEGF-A and VEGF-C and an activator of Tie2. Gersizangitide can block VEGF receptor signaling, inhibit vascular leakage, neovascularization and inflammation. Gersizangitide can be used in the research of diseases related to ocular neovascularization and angiogenesis.
