代谢
简单的脂肪族和芳香族硫醇在哺乳动物中发生S-甲基化反应,生成相应的甲硫醚或硫化合物。甲基化反应由细胞质中的硫嘌呤甲基转移酶和微粒体中的硫醇甲基转移酶催化,两个反应都需要S-腺苷-L-甲硫氨酸作为甲基供体。硫嘌呤甲基转移酶存在于人肝、肾和红细胞中;这种酶的首选底物包括芳香族和杂环硫醇。脂肪族硫醇的S-甲基化由微粒体硫醇甲基转移酶催化,生成的甲硫醚(硫化合物)代谢物会经历S-氧化,产生作为尿液产物的甲亚砜和甲砜类似物。硫醇可能会与谷胱甘肽和其他内源性硫醇物质反应形成混合二硫键。据报道,微粒体和细胞质硫醇转移酶都能催化混合二硫键的形成。生成的混合二硫键可以经过还原回到硫醇,氧化脱硫,或者通过中间体硫代硫酸盐和亚硫酸酸氧化成磺酸。在循环中的主要形式可能是与白蛋白形成的混合二硫键。/简单硫醇/
Simple aliphatic and aromatic thiols undergo S-methylation in mammals to produce the corresponding methyl thioether or sulfide. Methylation is catalysed by thiopurine methyltransferase in the cytoplasm and thiol methyltransferase in microsomes, and both reactions require S-adenosyl-l-methionine as a methyl group donor. Thiopurine methyltransferase is present in human liver, kidney, and erythrocytes; preferential substrates for this enzyme include aromatic and heterocyclic thiols. S-Methylation of aliphatic thiols is catalysed by microsomal thiol methyltransferase, and the resulting methyl thioether (sulfide) metabolite would undergo S-oxidation to give the methyl sulfoxide and methyl sulfone analogues as urinary products. Thiols may react with glutathione and other endogenous thiol substances to form mixed disulfides. Both microsomal and cytoplasmic thioltransferasess have been reported to catalyse the formation of mixed disulfides. The resulting mixed disulfides can undergo reduction back to thiols, oxidative desulfuration, or oxidation to a sulfonic acid via the intermediate thiosulfinate and sulfinic acids. The principal form in the circulation would probably be a mixed disulfide formed with albumin. /Simple thiols/

    摘要:
    Abstract Objective The development of an efficient, multifunctional drug delivery system overcoming different obstacles generally associated with drug formulations, including the poor accumulation of the active principle in the target site and its sustained release for prolonged time. Methods Our study proposes the development of a fluorinated poly(amidoamine) (PAMAM) carrier prodrug combining drug release boosted in alkaline environments with a possible implementation in 19F MRI applications. In particular, we functionalized the terminal primary amines of PAMAM G2 and G4 through an ad hoc designed fluorinated ibuprofen-arginine Michael acceptor to obtain multifunctional ibuprofen-PAMAM-Arg conjugates. Results These carriers demonstrated pH-dependent and sustained ibuprofen release for more than 5 days. This advantage was observed in both weak alkaline and physiological buffer solutions, allowing to overcome the limits associated to the burst release from similar fluorinated Arg-PAMAM dendrimers with ibuprofen physically encapsulated. Conclusion These findings, coupled to the high biocompatibility of the system, suggest a potential synergistic biomedical application of our conjugates, serving as vehicles for drug delivery and as 19F magnetic resonance imaging contrast agents.

  • Catalyst-Controlled Regiodivergent Synthesis of 1- and 3-Thiosugars with High Stereoselectivity and Chemoselectivity
    作者:Yuexin Liu、Yang Jiao、Huajun Luo、Nianyu Huang、Mengnan Lai、Kun Zou、Hui Yao

    日期:2021.5.7
    An effective regiodivergent synthesis toward 1- and 3-thiosugars was achieved through palladium and cobalt catalysis, respectively. β-1-Thiosugars were obtained from 3,4-O-carbonate-glycals and various thiols catalyzed by Pd2(dba)3 in good yields with exclusive stereoselectivity and chemoselectivity, while only (3S)-3-thiosugars were generated via Co(BF4)2. Experiments and DFT calculations supported
    通过钯和钴催化分别实现了对1-硫代糖和3-硫代糖的有效区域发散合成。从3,4- O-碳酸盐-糖和Pd 2(dba)3催化的各种硫醇以良好的产率获得β-1-硫代糖醇,并具有独有的立体选择性和化学选择性,而仅通过生成(3 S)-3-硫代糖钴(BF 4)2。实验和DFT计算支持所提出的机理,即在Pd条件下,硫醇基团更愿意与C4-氧从上表面形成氢键,而在Co条件下,硫醇会与钴从下表面形成氢键。关键中间体的Pd / Co-C1和Pd / Co-C3键长之间的差异为1,3-区域选择性提供了进一步的见解。

All these complexes were found to catalyse the oxydant-free double dehydrogenation of primary amine into nitrile. Ru complex bearing NHC-functionalised S-tBu group was further investigated in a wide range of amines and was found more selective for alkyl amine substrates than
