• Amino-acid platforms loaded with various two different drugs were synthesized.
• They were synthesized by fast SPOC, accelerating discovery process.
• They possess a linkage tether for conjugation to a peptide carrier.
• They provide discrete chemo- and bio-release profiles for each drug.
• They enable “switch off/switch on” regulation of cytotoxicity by cell targeting.
Bi-nuclear amino acid platforms loaded with various drugs for conjugation to a peptide carrier were synthesized using simple and convenient orthogonally protective solid-phase organic synthesis (SPOS). Each arm of the platform carries a different anticancer agent linked through the same or different functional group, providing discrete chemo- and bio-release profiles for each drug, and also enabling “switch off/switch on” regulation of drug cytotoxicity by conjugation to the platform and to a cell targeting peptide. The versatility of this approach enables efficient production of drug-loaded platforms and determination of favorable drug combinations/modes of linkage for subsequent conjugation to a carrier moiety for targeted cancer cell therapy. The results presented here potentiate the application of amino acid platforms for targeted drug delivery (TDD).
