Objective: The present study on garlic cloves (Allium sativum) belongs to family Amaryllidaceae has been focused. This is a natural medicinal plant used for disease preventions against all kinds of internal infections. Preliminary screening of phytochemicals has found plenty of secondary metabolites which are present in garlic cloves. Their functional groups and mineral compositions, the potent...

N-Heteroarene substitution into biphenyl-based linkers enhances the uptake of electron-rich organosulfur molecules in a series of isostructural microporous coordination polymers.

Microbial metabolism of organosulfur compounds is of interest in the petroleum industry for in-field viscosity reduction and desulfurization. Here, dibenzyl sulfide (DBS) metabolism in white rot fungi was studied. Trametes trogii UAMH 8156, Trametes hirsuta UAMH 8165, Phanerochaete chrysosporium ATCC 24725, Trametes versicolor IFO 30340 (formerly Coriolus sp.), and Tyromyces palustris IFO 30339...

Isothiocyanates (ITCs), naturally occurring in abundance in cruciferous vegetables, are the most well-studied organosulfur compounds having an electrophilic reactivity. ITCs have been accepted as major ingredients of these vegetables that afford their health promoting potentials. ITCs are able to modulate protein functions related to drug-metabolizing enzymes, transporters, kinases and phosphat...

Thiosulfinates (TSs) have been implicated as a principle source of the antiplatelet property of raw onion and garlic juice. The in vitro responses of human platelets to dosages of four TSs were measured using whole blood aggregometry and compared by regression analysis. Of the compounds evaluated, methyl methane-TS (MMTS), propyl propane-TS (PPTS), and 2-propenyl 2-propene-TS (allicin) are pres...

The title compound, C(19)H(15)ClN(2)S, a divalent organosulfur compound belonging to the class of ortho-mercaptoazo compounds, is non-ionic in nature. The azo group in the mol-ecule is moved away from the S atom to attain the stable trans-azo configuration. Here the S atom is not electron deficient, so no intra-molecular N⋯S inter-action exists. Due to steric reasons, the mol-ecule is non-plana...

Kinetic resolution is an important method for the separation of racemates into their component enantiomers. Thiols are precursors to a variety of organosulfur compounds, with high utility in both chemistry and chemical biology, yet there is a surprising dearth of methodologies for their direct and efficient catalytic kinetic resolution. Here, we demonstrate an organocatalytic process involving ...

Paenibacillus sp. strain A2 is a Gram-negative rod-shaped bacterium isolated from a mixture of formation water and petroleum in Daqing oilfield, China. This facultative aerobic bacterium was found to have a broad capacity for metabolizing hydrocarbon and organosulfur compounds, which are the main reasons for the interest in sequencing its genome. Here we describe the features of Paenibacillus s...

Covering: up to the end of 2017While suggestions concerning the possible role of metals in olfaction and taste date back 50 years, only recently has it been possible to confirm these proposals with experiments involving individual olfactory receptors (ORs). A detailed discussion of recent experimental results demonstrating the key role of metals in enhancing the response of human and other vert...

Organosulfur compounds (OSCs) present in garlic and onion oil have been shown to inhibit chemical carcinogenesis. In this study, we compared the chemopreventive efficacy of five lipid- and four water-soluble OSCs using the murine nuclear aberration assay. Administration of diallyl sulfide and S-allyl cysteine p.o. at a dose of 200 mg/kg 3 h prior to i.p. 1,2-dimethylhydrazine (DMH) injection (2...
