Ten new RGD (Arginine-Glycine-Aspartic acid) peptidomimetics have been synthesized and screened for their affinity to αvβ3 integrin receptor. Arginine and Aspartic acid mimetic subunits were connected through 1,2,3-triazole as central scaffold by click chemistry, affording the final products with good yields. Among them, compounds 3f-j exhibited high affinity to the receptor,with IC50 in the low nanomolar range, comparable to that of the reference compound Cilengitide.
合成了10个新的RGD(精氨酸-甘氨酸-天冬氨酸)模拟肽,并测试了它们对αvβ3整合素受体的亲和力。精氨酸和天冬氨酸模拟亚基通过点击化学,以1,2,3-三氮唑作为中心骨架相连,最终产物收率良好。其中,化合物3f-j对受体表现出高亲和力,IC50值在低纳摩尔范围,与参比化合物西仑吉肽相当。
