The successful design and pre-clicked synthesis of a non-toxic and cytosol trackable carboplatin-like near infrared fluorophore conjugate via strain-promoted azide alkyne cycloaddition (SPAAC) is reported. Reaction of cis-[Pt(2-azidopropane-1,3-diamine)(cbdca)] (cbdca = cyclobutane-1,1-dicarboxylato) and a bicyclo[6.1.0]non-4-yne near-infrared (NIR) azadipyrromethene fluorophore gave the corresponding clicked Pt-Fluorophore conjugate. The X-ray crystal structure of cis-[Pt(2-azidopropane-1,3-diamine)(cbdca)] was determined featuring the azide on the bidentate 1,3-diaminopropane ligand. The Pt-fluorophore conjugate is the first example of a Pt conjugate clicked via strain-promoted azide alkyne cycloaddition (SPAAC) where the reactive azide handle is on the amine ...
