  摘要：

  通过电化学方法合成了六种天然尤格洛布林。关键步骤是在聚四氟乙烯纤维涂层电极表面，现场生成的喹诺甲烷与萜类化合物进行环加成反应，以2,3-二氯-5,6-二氰基对苯二酚（DDQH2）作为氧化还原介质，得到天然产物。在该反应体系中，通过对甲酚衍生物的选择性氧化，高效地完成了不稳定喹诺甲烷的仿生生成和环加成反应。

  biological processes governed by these modifications. Phloroglucinol meroterpenoids constitute one of the most expansive classes of natural products, displaying a plethora of biological activities. However, their mechanism of action and cellular targets have, until now, remained elusive. In this study, we detail the concise biomimetic synthesis, computational mechanistic insights, physicochemical attributes

  天然产物常年成为药物先导物和化学探针的多产来源，推动了许多治疗方法的发展。尽管它们稀缺，但通过与赖氨酸残基的共价相互作用调节蛋白质功能的天然产物具有巨大的潜力，可以解锁新的治疗干预措施，并促进我们对受这些修饰控制的生物过程的理解。间苯三酚硫萜类化合物是最广泛的天然产物类别之一，显示出大量的生物活性。然而，直到现在，它们的作用机制和细胞靶标仍然难以捉摸。在这项研究中，我们详细介绍了几种间苯三酚甲萜类化合物的简明仿生合成、计算机制、物理化学属性、动力学参数、分子作用机制和功能性细胞靶标。我们利用天然产物的合成可点击类似物，通过凝胶内荧光扫描和细胞成像来探测它们不同的蛋白质组范围反应性和亚细胞定位。通过实施样品多路复用和重新设计的赖氨酸靶向探针，我们简化了基于定量活性的蛋白质分析，从而能够直接绘制人类细胞中蛋白质赖氨酸的整体反应性和配体性。利用这个框架，我们在乳腺癌细胞中可处理的蛋白质位点确定了

  In the present communication, naturally occurring phloroglucinol-monoterpene adducts, euglobals G1-G4 (3b/a and 4a/b) and 16 new analogues (13a/b-18a/b and 19-22) were synthesized by biomimetic approach. These synthetic compounds differ from natural euglobals in the nature of monoterpene and acyl functionality. All of these compounds were evaluated for their antibacterial, antifungal, antileishmanial and antimalarial activities. Analogue 17b possessed good antibacterial activity against methicillin-resistant Staphylococcus aureus, while analogues 19-22 possessed potent antifungal activity against Candida glabrata with IC(50)s ranging from 1.5 to 2.5 mu g/mL. Euglobals along with all synthesized analogues exhibited antileishmanial activity. Amongst these, euglobal G2 (3a), G3 (4a) and analogues 13a and 14a showed potent antileishmanial activity with IC50s ranging from 2.8 to 3.9 mu g/mL. Analogue 16a possessed antimalarial activity against chloroquine sensitive D6 clone of Plasmodium falciparum. None of the compounds showed toxicity against mammalian kidney fibroblasts (vero cells) upto the concentration of 4.76 mu g/ml. (c) 2005 Elsevier Ltd. All rights reserved.
