Garlic-derived polysulfides (e.g., diallyl trisulfide, DATS) act as potent donors of the cell-signalling mediator H2S when exposed to endogenous thiols. Inspired by this chemistry, we incorporated a trisulfide linkage into a conjugate comprising an mPEG tail and a cholesteryl head via thiol-mediated fragmentation chemistry. The synthesized conjugate releases H2S upon exposure to thiol even at intracellular

by the properties of the naturally occurring H2S donor, diallyl trisulfide (DATS, extracted from garlic), the biological behaviour of trisulfide-bearing PEG-conjugates was explored. Specifically, three conjugates comprising an mPEG tail and a cholesteryl head were investigated: conjugates bridged by a trisulfide linker (T), a disulfide linker (D) or a carbamate linker (C), and a fourth comprising two
