iRGD peptide c(CRGDKGPDC)

产品介绍

iRGD peptide 是一种由 9 个氨基酸组成的环肽，先与 av integrins 结合，随后酶解产生 CRGDK/R 与神经纤毛蛋白-1 (neuropilin-1) 相互作用，从而促进活性分子的组织渗透，具有靶向肿瘤、肿瘤渗透的作用。

生物活性

iRGD peptide is a 9-amino acid cyclic peptide, triggers tissue penetration of agents by first binding to av integrins, then proteolytically cleaved in the tumor to produce CRGDK/R to interact with neuropilin-1, and has tumor-targeting and tumor-penetrating properties.

体外研究

iRGD peptide-mediated tumor penetration occurs in three steps: binding to αv-integrins on tumor vasculature or tumor cells, exposure by proteolysis of a C-terminal motif that binds to neuropilin-1 (NRP-1) and cell internalization. iRGD peptide inserted in the ICOVIR15K fiber C terminus enhances binding and internalization only in MCF7 cells, which express NRP-1 and integrins. iRGD insertion does not impair virus infection and replication. iRGD peptide alone has no obvious effect on gastric cancer cells, and when combined with 5-FU, iRGD peptide (0.3 μmol/mL) enhances the chemotherapy efficacy of 5-FU on gastric cancer cells through NRP1.

体内研究

iRGD inserted in the oncolytic adenovirus ICOVIR15K (ICOVIR15K-iRGD) enhances early adenovirus dissemination through the tumor mass and elevates the antitumor effect in mice. iRGD (4 mmol/kg, i.v.) in combination with 5-FU significantly suppresses the tumor growth in nude mice bearing human gastric cancer cells.
