mechanism that relies on the thermodynamics of a mixeddisulphide exchange reaction. Disulphide (1) and thiosulfonate (11) were further evaluated mechanistically and found to induce G2/M cell-cycle arrest and apoptosis, inhibit cell proliferation, and generate ROS. When the ROS produced by 1 and 11 were quenched with Trolox, ascorbic acid or N-acetyl cysteine (NAC), only NAC was found to counter the cytotoxicity

The asymmetric α‐sulfenylation of Ni(II) complex of glycine with S‐substituted 4‐methylbenzenesulfonothioate is reported. Due to the mild and simple reaction conditions, this asymmetric reaction is compatible with various functional groups.

organosulfur compound ajoene derived from the rearrangement of allicin found in crushed garlic can inhibit the proliferation of tumour cells by inducing G2/M cell cycle arrest and apoptosis. We report on the application of a concise four-step synthesis (Hunter et al., 2008 [1]) that allows access to ajoene analogues with the end allyl groups substituted. A library of twelve such derivatives tested for

A novel organic sulfur compound, a method for preparing the same, and a pharmaceutical composition for preventing or treating cancer or inflammatory diseases, containing the same as an active ingredient are provided. The novel organic sulfur compound is capable of excellently inhibiting histone deacetylated (HDAC) enzymes in a concentration of nanomolar or micromolar units and has been found to have an excellent effect against inflammatory diseases, and has been found to be capable of inhibiting the proliferation of cancer.
organocatalyzed 1,3-thiosulfonylation has been developed to straightforwardly access highly functionalized vinyl sulfones, which features mild conditions, atom- and step-economy, practicability, conciseness, and environmental friendliness. Moreover, these valuable products can be transformed to vinylsulfides via a base-promoted isomerization. The versatile route can efficiently and rapidly introduce SCD3 groups
