TP53-induced glycolysis and apoptosis regulator (TIGAR) alleviates oxidative stress protects against ischemic neuronal injury by shifting glucose metabolism into the pentose phosphate pathway (PPP). However, brain alters from PPP to during prolonged ischemia. It is still unknown whether how TIGAR exerts antioxidant activity neuroprotection in brains. Here, we determined significant upregulation of that was proportional duration failed upregulate NADPH level but alleviated cells with oxygen...

Abstract A catalyst-free, three-component dearomatization of phenols with aryldiazonium tetrafluoroborates and DABCO·(SO2)2 has been developed for the synthesis 4-(arylsulfonyl)cyclohex-2,5-dien-1-one scaffolds. This method offers mild reaction conditions high step efficiency, providing a green efficient strategy phenols. Mechanistic studies indicated that this transformation relies on tandem radical sulfur dioxide insertion process.
