αIIb β3 receptors was investigated by molecular modeling simulations. Lead compound 12 was successfully radiofluorinated and used for in vivo positronemissiontomography/computed tomography (PET/CT) studies in U87 tumor models, which showed only modest tumor uptake and retention, owing to rapid excretion. These results demonstrate that the novel click RGD mimics are excellent radiolabeledprobes for in vitro
Fibrinogen receptor antagonists of the formula: ##STR1## are disclosed for use in inhibiting the aggregation of blood platelets. wherein G is: ##STR2##
A 2,3-diaminopropionic acid derivative represented by general formula (1) or a pharmaceutically acceptable salt thereof. This compound is useful as a platelet aggregation inhibitor, cancer metastasis inhibitor, wound remedy or bone resorption inhibitor.
