iRGD peptide 1 TFA 是一种原型肿瘤特异性组织穿透肽，可将药物深深地输送到血管外肿瘤组织中，并具有抗转移活性。
iRGD peptide 1 TFA is the prototypic tumor-specific tissue-penetrating peptide, which delivers drugs deep into extravascular tumor tissue. iRGD peptide 1 TFA has anti-metastatic activity[1].
iRGD peptide 1 (iRGD) inhibits migration of tumor cells and caused chemorepulsion in vitro in a CendR- and NRP-1-dependent manner. iRGD peptide 1 induces dramatic collapse of cellular processes and partial cell detachment, resulting in the repellent activity. These effects are prominently displayed when the cells are seeded on fibronectin, suggesting a role of CendR in functional regulation of integrins[1].
iRGD peptide 1 (amino acid sequence: CRGDKGPDC; 4 μmol/kg; intravenous injection; every other day; for 21 days) potently inhibits spontaneous metastasis in mice[1].
