TP508 是一种 23 个氨基酸的非蛋白水解凝血酶肽，代表凝血酶分子受体结合结构域的一部分。TP508 可激活内皮 NO synthase (eNOS) 并刺激人内皮细胞中 NO 的产生。TP508 通过激活内皮细胞和干细胞以使血管再生和组织再生。

体外研究：TP508 (50 μg/mL; 24 hours; HCAEC) treatment reverses radiation-induced endothelial dysfunction (ED) and loss of NO signaling by attenuating the downregulation of eNOS expression. TP508 treatment is able to stimulate NO production in the irradiated cells[1].
TP508 mitigates effects of nuclear radiation on human endothelial cells in culture restoring endothelial NO production, tube formation and accelerating repair of radiation-induced DNA double-strand breaks (DSB)[1].
TP508 acts as an antagonist for the effects of thrombin. TP508 peptide inhibits these thrombin-induced effects through a RGD and αvβ3-related mechanism
体内研究：TP508 (10 mg/kg; intravenous injection; male CD-1 mice) treatment mitigates radiation-induced endothelial cell damage, also significantly increases survival of CD-1 mice when injected 24 h after 8.5 Gy exposure
