GX1 (Cyclo(CGNSNPKSC))

C₃₃H₅₄N₁₂O₁₄S₂ · 906.98 g/mol

GX1 is a synthetic 9-amino-acid cyclic peptide stabilized by an intramolecular Cys¹–Cys⁹ disulfide bond, studied as a tumor-vasculature-targeting research reagent. It is investigated for gastric-cancer vascular endothelium binding, anti-angiogenic activity in endothelial cell-proliferation and tube-formation assays, molecular-imaging probe development, and targeted nanomedicine-conjugation research.
