(RGD) recognition site on the binding pocket of integrin αvβ3, tetraiodothyroacetic acid (tetrac, a deaminated derivative of T4) is a thyrointegrin receptor antagonist and blocks the actions of T3 and T4 as well as different growth factors-mediated angiogenesis. In this study, we synthesized novel tetrac analogs by modifying the phenolic moiety of tetrac and tested them for their anti-angiogenesis
在血管生成过程中,整联蛋白是细胞表面跨膜受体家族的成员,在血管形成和血管生长因子的局部释放中起着至关重要的作用。甲状腺激素,例如升-thyroxine(T 4)和3,5,3'-三碘-升-甲腺氨酸(T 3),通过整合素αvβ3受体促进血管发生和肿瘤细胞增殖。处或附近的精氨酸-甘氨酸-天门冬氨酸上的整合素α结合口袋(RGD)的识别位点v β 3,tetraiodothyroacetic酸(tetrac,T的脱氨基衍生物4)是thyrointegrin受体拮抗剂和块T的动作3和第4以及不同的生长因子介导的血管生成。在这项研究中,我们通过修饰tetrac的酚部分合成了新颖的tetrac类似物,并使用用于小鼠血管生成的Matrigel栓塞模型测试了它们的抗血管生成活性。药理活性结果表明,tetrac可以适应多种修饰并保持其抗血管生成活性。
