Assembly of independent chemical modules through oxorhenium coordination by a NS2 + S chelation motif was applied to the synthesis of RGD (Arg-Gly-Asp) analogs. Modules were assembled through oxorhenium chelation to give a series of 18 metal complexes in good yields and satisfactory purities. Screening of these oxorhenium coordinates as antagonists of integrins alpha V beta 3, alpha IIb beta 3 and alpha V beta 5 led to the identification of 3 bioactive compounds that exhibit submicromolar affinities for the 3 integrins. Preliminary studies showed that the corresponding oxotechnetium complexes are stable in mice plasma and therefore could be proposed for the molecular imaging of pathologies that overexpress integrins alpha V beta 3 and alpha V beta 5.
