Abstract: 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.
