The bulbous root garlic (Allium sativum) with a strong taste and pungent odor is used widely in culinary preparations and folk medicine. Silver and gold nanoparticles (NPs) synthesized using this ingredient have also shown medicinal and therapeutic potency. Garlic contains organosulfur compounds, such as diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS). These compounds are of crucial significance as anticancer drugs. Reported here is a synthesis of a series of DATS with varying substituents and plausible application as capping as well as reducing agent to synthesize gold nanoparticles (TS-GNPs). In the process, it was discovered that among the selected DATs, only 1,3-di(but-1-ene)trisulfane could serve the purpose because of structural reasons. The reason for this intriguing selectivity has been investigated in detail using the experimental findings and theoretical calculations of the frontier molecular orbitals (FMO). Graphic abstract: Synthesis of a series of medicinally important symmetrical organic trisulfides as a structural analogue of diallyl trisulfides (DATS) in an attempt to construct organosulfur compound induced gold nanoparticles (GNPs), has been reported. Only 1,3-Di(but-1-ene)trisulfane in the lot is capable of reducing the chloroauric acid to synthesize the protected GNPs.[Figure not available: see fulltext.].

Temperature-and solvent-induced selective synthesis of trisulfides and disulfides is demonstrated. A remarkable selectivity was achieved using Na2S as a sulfur-Transfer agent under mild, greener, catalyst-free and additive-free conditions. This study reveals trisulfides as a better model than disulfides in general for a sustained release of H2S and potent anti-cancer activities.

A strategy to deliver a well-defined persulfide species in a biological medium is described. Under near physiological conditions, the persulfide prodrug can be activated by an esterase to generate a “hydroxymethyl persulfide” intermediate, which rapidly collapses to form a defined persulfide. Such persulfide prodrugs can be used either as chemical tools to study persulfide chemistry and biology or for future development as H2S-based therapeutic reagents. Using the persulfide prodrugs developed in this study, the reactivity between S-methyl methanethiosulfonate (MMTS) with persulfide was unambiguously demonstrated. Furthermore, a representative prodrug exhibited potent cardioprotective effects in a murine model of myocardial ischemia-reperfusion (MI/R) injury with a bell shape therapeutic profile.
