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.

Antifungal, cytotoxic and SAR studies of a series of N-alkyl, N-aryl and N-alkylphenyl-1,4-pyrrolediones and related compounds
The synthesis, in vitro evaluation and SAR studies of 67 maleimides and derivatives acting as antifungal agents are reported. A detailed SAR study supported by theoretical calculations led us to determine that: an intact maleimido ring appears to be necessary for a strong antifungal activity, dissimilarly affected by the substituents in positions 2 and 3. The best activities were shown by 2,3-nonsubstituted

efficient [2+2] cycloaddition between maleimides and unsaturated moieties, utilizing a visible-light triplet sensitization mode, has been developed for the direct synthesis of multifunctional 3-azabicyclo[3.2.0]heptane derivatives. This reaction relies on selective activation of the maleimide functionality upon energy transfer from a new photosensitizer that outperforms diverse well-established photosensitizers

applying photocatalytic systems to activate substrates becomes increasingly popular. Although photosensitizers serve as the core of the photocatalytic reaction, the design of a photosensitizer has not been taken for granted. By modifying ligands of organometallic complexes to optimize properties of photosensitizers, we successfully achieved a series of iridium complexes with long excited triplet-state lifetime
