Preparation of a new class of heterocyclic compounds pharmacologically active as anti-infectives, structurally correlated with 1,5-dihydro-2H-pyrrol-2-one.
While investigating the antioxidant properties of aminoethylcysteine ketimine decarboxylated dimer ( 1) ( a natural substance occurring in biological fluids such as human urine and plasma and in bovine cerebellum), a previously unreported oxidation product was obtained. This compound was identified and characterized through comparison with an authentic sample prepared via Pd-catalyzed dehydrogenation of 1. This molecule is an example of an alternative oxidation pathway involving 1.

elucidate the structure of the product resulting from the interaction of 2 with peroxynitrite using 1D and 2D NMR experiments and ion trap mass spectrometry. This product is a dimerized form of 2 and is hereafter referred to as 3. During the reactions leading to 2 and during the formation of 3, no chiral selection is operated; all optical isomers are present in D2O and have been evidenced by 1H NMR methods
氨基乙基半胱氨酸酮亚胺脱羧二聚体(2)是具有抗氧化性能的天然硫化合物。2抑制过氧亚硝酸盐(一种与多种生物分子发生反应的强氧化剂和硝化剂)介导的某些反应。这项工作旨在通过1D和2D NMR实验以及离子阱质谱法,阐明2与过氧亚硝酸盐相互作用产生的产物结构。该产物是2的二聚体形式,以下称为3。在导致2的反应过程中和在3的形成过程中,不进行手性选择。所有的光学异构体都存在于D 2中O,并已通过1 H NMR方法在D 2 O加β-或γ-环糊精中得到证实。
