Abstract
Membrane forming synthetic lipids constitutes a new class of biomaterials with impressive applications in the field of biological and pharmaceutical sciences. Interestingly, alteration(s) in the headgroup region of the lipids offer a wide chemical space to investigate their specific properties. In this regard, we have utilized β-azidophosphonate chemistry to gain access to a novel class of triazole-phosphonate (TP) amphiphiles with fascinating physicochemical properties of lipids. TP lipids form stable vesicles that exhibit negative surface potential across a broad pH range. These anionic lipids have high phase-transition temperatures, phospholipase resistance, slow vesicle leakage profiles, and doxorubicin delivery efficacy. We hypothesize that these readily synthesizable phosphonolipids could find several applications as phospholipid substituents.
