Target

IC50: 0.94 nM (αvβ3 integrin)[1].

In Vitro Cyclo(-RGDfK) is a potent and selective inhibitor of the αvβ3 integrin, with a IC50 of 0.94 nM[1]. [(66)Ga]DOTA-E-[c(RGDfK)]2 can be prepared with high radiochemical purity (>97%), specific activity (36-67GBq/μM), in vitro stability, and moderate protein binding. MicroPET imaging up to 24 post-injection showed contrasting tumors reflecting αvβ3-targeted tracer accumulation[2].
