action is quickly terminated via enzymatic hydrolysis catalyzed by monoglyceride lipase (MGL). Regulating its endogenous level could offer therapeutic opportunities; however, few selective MGL inhibitors have been described so far. Here, we describe the synthesis of N-substituted maleimides and their pharmacological evaluation on the recombinant human fatty acid amide hydrolase (FAAH) and on the purified
内源性大麻素2-花生四烯酸甘油酯(2-AG)在许多生理过程中起着重要作用,其作用通过甘油单酯脂肪酶(MGL)催化的酶促水解迅速终止。调节其内源水平可以提供治疗机会;然而,到目前为止,几乎没有描述选择性的MGL抑制剂。在这里,我们描述了N-取代的马来酰亚胺的合成及其对重组人脂肪酸酰胺水解酶(FAAH)和纯化人MGL的药理评价。先前已经描述了一些N-芳基马来酰亚胺(萨里奥(SM);萨洛(OM);Nevalainen,T .;Poso,A。莱蒂宁(JT);贾文恩(T.

A Mn(I)-catalyzed site-selective nondirected C3-maleimidation of quinoxaline is established. Herein, the electrophilic C3-metalation precedes over the o-directed strategy to access diversely substituted quinoxaline-appended succinimides. The products undergo PIFA-promoted C(sp2)–C(sp3) spirocyclization via π-electrons drifting from aryls and Selectfluor-mediated dehydrogenation of succinimide at room

visible light-driven di-functionalization of maleimide with disulfide and in situ-generated singletoxygen offers selective 1,2-thiohydroxylation under additive-free conditions. Here the disulfide plays the dual role of photosensitizer and the coupling reagent. Notably, the hydroxyl functionality originates from the in situ generated singletoxygen followed by HAT from H2O (moisture).
可见光驱动的马来酰亚胺与二硫化物和原位产生的单线态氧的双官能化可在无添加剂的条件下提供选择性的 1,2-硫代羟基化。此处二硫化物起到光敏剂和偶联剂的双重作用。值得注意的是,羟基官能团源自原位生成的单线态氧,随后是来自 H 2 O(水分)的 HAT。
A reagent-less sensitizer-free photo-induced access of oxygenated centers via hindered tertiary hydroxylation (Csp3-H) and intramolecular spiro-etherification (Csp3-H/Csp2-H) of photo-responsive C3-maleimidated quinoxaline has been demonstrated. This is an illustrative example of a tautomeric reacting substrate-induced singlet oxygen up-taken divergent photo-oxygenation, guided by the use of a suitable
