Chiral Quaternary Ammonium Salt‐Catalyzed Enantioselective Addition Reactions of Hydantoins
Abstract We herein report a protocol for the asymmetric 1,4‐addition of hydantoins to various Michael acceptors by utilizing Cinchona alkaloid‐based chiral quaternary ammonium salt catalysts. Various products were obtained with moderate to good enantioselectivities and accompanying computational investigations helped to identify key interactions ...

Dopaminergic neuronal death via necroptosis in Parkinson's disease: A review of the literature
We reviewed the current literature on the potential role of necroptosis, a recently characterized regulated cell death mechanism, in Parkinson's disease (PD) pathogenesis. We summarized findings from studies on necroptosis in PD preclinical models and PD human tissue samples, discussing how manipulating necroptosis might open a novel therapeutic ...

Synthesis and molecular modeling studies of new thiohydantoin-triazole hybrids as anticancer agents
The targeted thiohydantoin-triazole hybrid compounds 5a-d and 9a-d were synthesized by the copper-catalyzed click reaction of 2-azido-N-arylacetamides 3a-d with the appropriate alkynes, thiohydantoin moiety linked to a propargyl group.

Abstract Immunoisolation of pancreatic islets in alginate microcapsules allows for transplantation in the absence of immunosuppression but graft survival time is still limited. This limited graft survival is caused by a combination of tissue responses to the encapsulating biomaterial and islets. A significant loss of islet cells occurs in the immediate

The exposure systems of glycidol‐related chemicals on the formation of glycidol‐hemoglobin adducts diHOPrVal were compared. DiHOPrVal formation was observed using several chemicals other than glycidol with different behaviors in vitro and in vivo. However, in both cases, the amount of diHOPrVal produced was very small compared with glycidol. This study

Synthese von 6-Thioxo-1,2,5-oxadiazinan-3-onen und Umwandlung in 3-Amino-2-thiohydantoine und 3-Hydroxy-2-thiohydantoine / Synthesis of 6-Thioxo-1,2,5-oxadiazinan-3-ones and Transformation into 3-Amino-2-thiohydantoins and 3-Hydroxy-2-thiohydantoins [PDF]
6-Thioxo-1,2,5-oxadiazinan-3-ones 5, easily available by cyclic thiocarbonylation of Nα ,Ndisubstituted α-aminocarbohydroxamic acids 4 with 1,1′-thiocarbonyldiimidazole, are transformed by hydrazine or hydroxylamine into 3-amino-2-thiohydantoins 6 and 3-hydroxy-2-thiohydantoins 7.
