“…Although the initial event in lipid-induced kidney damage has not been defined, oxidative stress is recognized as one of the most significant pathogenic mechanisms. The inhibition of lipid deposition [20–22] and decreases in ROS and inflammation levels [23–25] could improve impaired kidney function. In the current study, in addition to increased body weight, insulin resistance, and dyslipidemia, the rats fed with the HFD showed higher oxidative stress levels and impaired renal function, which were reflected by biomarkers of early renal impairment, including serum cystatin C, urine NAG activity, microalbuminuria, and Ccr [26–28].…”

Scope Several reports in the literature have suggested the renoprotective effects of ketone bodies and green tea polyphenols (GTPs). Our previous study found that GTP consumption could elevate the renal expression of the ketogenic rate-limiting enzyme, which was decreased by a high-fat diet (HFD) in rats. Here, we investigated whether ketogenesis can mediate renoprotection by GTPs against an HFD. Methods and Results Wistar rats were fed a standard or HFD with or without GTPs for 18 weeks. The renal oxidative stress level, kidney function, renal expression, and activity levels of mitochondrial 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthase 2 (HMGCS2) and sirtuin 3(SIRT3) were detected. The increased renal oxidative stress and the loss of renal function induced by the HFD were ameliorated by GTPs. Renal ketogenesis and SIRT3 expression and activity levels, which were reduced by the HFD, were restored by GTPs. In vitro, HEK293 cells were transfected with the eukaryotic expression plasmid pcDNA HMGCS2. GTP treatment could upregulate HMGCS2 and SIRT3 expression. Although SIRT3 expression was not affected by HMGCS2 transfection, the 4-hydroxy-2-nonenal (4-HNE) level and the acetyl-MnSOD (K122)/MnSOD ratio were reduced in HMGCS2-transfected cells in the context of H2O2. Conclusion The ketogenesis/SIRT3 pathway mediates the renoprotection of GTPs against the oxidative stress induced by an HFD.

[26,27] It was revealed that due to the presence of trichloromethyl (23) and nitro groups (25) on the dihydroisoquinoline skeleton, the oxaziridine became more electrophilic and the reaction of oxygen transfer into sulphide occured in absence of acid (see section 3.1.2).…”

Oxaziridines and diaziridines have been used as versatile intermediates due to their high ring strain as well as the reactive CÀ O/N bond, for the synthesis of diverse range of nitrogen containing compounds. In the past few decades, numerous novel and handy methodologies on the preparations and utilizations of both the oxaziridines and diaziridines have been developed. In spite of few published reviews in the area (almost a decade back), the synthetic communities have made tremendous progress in their preparations and utilizations. This review has demonstrated the comprehensive advancement in the chemistry of oxaziridines and diaziridines for the last few years (almost a decade). 2.4. Oxaziridines from Ketimines 3.

“…[19] Recently, dihydroisoquinoline oxaziridines have been shown to have potent hypolipidemic effect in high-fat diet-fed rats. [20] Furthermore, they are widely used as reagents and intermediates in the preparation of biologically active molecules [21][22][23] Nitrones were first used to trap free radicals in chemical systems and then subsequently in biochemical systems. More recently, several nitrones, including alpha-phenyl-tertbutylnitrone (PBN), have been shown to have potent biological activity in many experimental animal models.…”
