  Developing potent 5-LOX inhibitors especially, natural product based ones, are highly attractive. Coumaperine, a natural product found in white pepper and its derivatives were herein developed as 5-LOX inhibitors. We have synthesized twenty four derivatives, characterized and evaluated their 5-LOX inhibition potential. Coumaperine derivatives substituted with multiple hydroxy and multiple methoxy groups

  5-Lipoxygenase（5-LOX）是参与促炎性白三烯生物合成的关键酶，可导致哮喘。开发有效的5-LOX抑制剂，特别是基于天然产物的抑制剂，具有很高的吸引力。香豆碱是白胡椒及其衍生物中的天然产物，在本文中被开发为5-LOX抑制剂。我们已经合成了二十四个衍生物，表征并评估了它们对5-LOX的抑制潜力。取代有多个羟基和多个甲氧基的香豆碱衍生物表现出最佳的5-LOX抑制作用。CP-209（一种邻苯二酚型二羟基衍生物）和CP-262-F2（一种邻位三羟基衍生物）在20 µM时分别显示出对5-LOX的抑制率为82.7％和82.5％。它们的IC50值分别为2.1±0.2 µM和2.3±0.2 µM，与齐留通相当，IC50 = 1.4±0.2 µM。CP-155，亚甲基二氧基衍生物（天然产物）和CP-194（2,4,6-三甲氧基衍生物）在20 µM时分别显示出对5-LOX的抑制率为76.0％和77

  cellular factors, including the transcription Nuclear Factor kappa B (NF-κB); this factor is found to be upregulated in many inflammatory diseases, including those induced by bacterial infection. In this study, we tested 32 synthetic derivatives of coumaperine (CP), a known natural compound found in pepper (Piper nigrum), for Quorum Sensing Inhibition (QSI) and NF-κB inhibitory activities. Of the compounds

  称为群体感应（QS）的细菌通讯是减少毒力和治疗细菌感染的有希望的目标。感染会引起炎症，这一过程受许多细胞因子调节，包括转录核因子κB（NF-κB）；发现该因子在许多炎性疾病中被上调，包括细菌感染引起的那些。在这项研究中，我们测试了32种香豆素（CP）的合成衍生物，香豆素是一种在胡椒中发现的已知天然化合物（Piper nigrum），用于群体感应抑制（QSI）和NF-κB抑制活性。在测试的化合物中，发现有七个具有高QSI活性，三个抑制了细菌的生长，五个抑制了NF-κB。此外，某些CP化合物在一项以上的测试中具有活性。例如，化合物CP-286，CP-215和CP-158无细胞毒性，抑制NF-κB活化和QS，但不显示抗菌活性。CP-154抑制QS，降低NF-κB活化并抑制细菌生长。我们的结果表明，这些合成分子可能为进一步开发针对细菌感染的新型治疗剂提供基础。

  Parkinson's disease (PD) is a slowly progressive and complex neurodegenerative disorder. Up to date, there are no approved drugs that could slow or reverse the neurodegenerative process of PD. Here, we reported the synthesis of series of piperine analogues and the evaluation of their neuroprotective effects against hydrogen peroxide (H2O2) induced damage in the neuron-like PC12 cells. Among these analogues, 3b exhibited the most potent protection effect and its underlying mechanism was further investigated. Further results indicated that the ROS scavenging and cytoprotection effect of 3b might be related to the Nrf2 activation and upregulation of related phase II antioxidant enzymes, such as HO-1 and NQO1. In in vivo study, oral administration (100 mg/kg) of 3b significantly attenuated PD-associated behavioral deficits in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD and protected tyrosine hydroxylase-immunopositive dopaminergic neurons. Our results provided evidence that 3b might be a promising candidate for Parkinson's disease treatment. (C) 2020 Elsevier Masson SAS. All rights reserved.
