The use of graphene derivatives as supports improves the properties of heterogeneous catalysts, with graphene oxide (GO) being the most frequently employed. To explore greener possibilities as well as to get some insights into the role of the different gr

A simple sulfonylation strategy involving I2 and thiosulfonates, as sulfonyl-group precursors, is reported for the synthesis of vinyl sulfones. Sulfonyl radicals are presumed to be generated from thiosulfonates, which subsequently react with st

Decarboxylative sulfonylation of arylpropiolic acids has been achieved by simply employing Na2CO3as a promoter and arenesulfinic acids as sulfonylating reagents. This simple and environmentally benign transformation offers an alternative approach and allows for easy and rapid synthesis of E-Vinyl sulfones from arylpropiolic acids and arenesufinic acids.

Although the etiology of Parkinson's disease (PD) remains elusive, recent studies suggest that oxidative stress contributes to the cascade leading to dopaminergic (DAergic) neurodegeneration. The Nrf2 signaling is the main pathway responsible for cellular defense system against oxidative stress. Nrf2 is a transcription factor that regulates environmental stress response by inducing expression of antioxidant enzyme genes. We have synthesized novel vinyl sulfone derivatives. They exhibited a broad range of activities in inducing HO-1, whose gene expression is under the control of Nrf2. Among them, compound 12g was confirmed to activate Nrf2 and induce expression of the Nrf2-dependent antioxidant enzymes NQO1, GCLC, GLCM, and HO-1, at both mRNA and protein levels in DAergic neuronal cells. This was accompanied by protection of DAergic neurons in both in vitro and MPTP-induced in vivo models of PD. In addition, compound 12g effectively resulted in attenuation of the PD-associated behavioral deficits in the mouse model.
