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.

New bis-aromatic and heterocyclic trisulfide derivatives 5, 7-10 were synthesized by optimizing lead dibenzyl trisulfide natural product (4) to evaluate their anti-tumor activities. Five compounds 5-7, 9, and 10 exhibited potent anti-tumor activities against eight different tumor cell lines with low cytotoxicity against HepG2. Initial SAR was discussed, and MOA of these anti-microtubule agents was suggested based on cell kinetic response patterns observed on RT-CES system.

Unsymmetrical di- tri- and tetrasulfides can be prepared in a one-pot reaction using SO2Cl2 SCl2 and S2Cl2 respectively to permit coupling of the appropriate thiols.
