  Coumarin compounds as antibacterial agents

  摘要：

  The coumarin compounds are antibacterial agents. The emergence of drug-resistant bacteria calls for constant development of new antibacterial agents with the aim of generating medicaments that are potent against drug sensitive and resistant bacteria and are well tolerated. The present compounds are not only new, but have very valuable antimicrobial properties. These compounds showed a broad spectrum of activity against gram-positive and gram-negative bacteria, as well tuberculosis mycobacteria. They also showed potent activity against drug-resistant bacteria, such as MRSA and VRSA. The molecular target of these compounds was identified as DNA Gyrase B. Based on their pharmacological profiles, the present compounds may find important clinical applications for severe infectious diseases and tuberculosis.

  Synthesis and Structure-Activity Relationships of Novel Amino/Nitro Substituted 3-Arylcoumarins as Antibacterial Agents

  摘要：

  我们合成了一系列新的氨基/硝基取代的 3-芳基香豆素，并评估了它们对临床分离的金黄色葡萄球菌（革兰氏阳性）和大肠杆菌（革兰氏阴性）的抗菌活性。其中一些分子对金黄色葡萄球菌的抗菌活性与所用标准（草酸和氨苄西林）相当。初步的结构-活性关系（SAR）研究表明，对金黄色葡萄球菌的抗菌活性取决于 3-芳基香豆素取代模式的位置。为了寻找抗菌活性和选择性的结构特征，本手稿报告了 3-芳基香豆素支架上硝基、甲基、甲氧基、氨基和溴取代基的不同位置。

  The procedure consists of a sequence of some reactions including an arylation/decarboxylation cascade and proceeds well in aqueous media to afford biologically interesting flavones and 3-arylcoumarins. This method exhibited excellent selectivity and functional group tolerance under mild conditions. The reaction also showed perfect efficacy for the preparation of styryl coumarins.

  Monoamine oxidase (MAO) is an important drug target for the treatment of neurological disorders. Several 3‐arylcoumarin derivatives were previously described as interesting selective MAO‐B inhibitors. Preserving the trans‐stilbene structure, a series of 2‐arylbenzofuran and corresponding 3‐arylcoumarin derivatives were synthesized and evaluated as inhibitors of both MAO isoforms, MAO‐A and MAO‐B. In general

  单胺氧化酶（MAO）是治疗神经系统疾病的重要药物靶标。以前有几种3-芳基香豆素衍生物被描述为有趣的选择性MAO-B抑制剂。保留了反式二苯乙烯结构，合成了一系列的2-芳基苯并呋喃衍生物和相应的3-芳基香豆素衍生物，并将其评估为MAO-A和MAO-B的抑制剂。通常，发现两种类型的衍生物都是选择性的MAO-B抑制剂，IC 50值在纳摩尔至微摩尔范围内。5-硝基-2-（4-甲氧基苯基）苯并呋喃（8）是苯并呋喃系列中活性最高的化合物，具有MAO-B选择性和可逆抑制作用（IC 50 = 140 n M）。具有与化合物8相同的取代模式的3-（4'-甲氧基苯基）-6-硝基香豆素（15）被发现是香豆素系列中活性最高的MAO-B抑制剂（IC 50 = 3 n M） 。但是，3-苯基香豆素14的活性在相同范围内（IC 50 = 6 n M），可逆，并且选择性也比化合物15高出几倍。将最具活性的化合物对接到MAO

  Overproduction of uric acid in the body leads to hyperuricemia, which is also closely related to gout. Uric acid production can be lowered by xanthine oxidase (XO) inhibitors. Inhibition of XO has also been proposed as a mechanism for improving cardiovascular health. Therefore, the search for new efficient XO inhibitors is an interesting topic in drug discovery. 3-Phenylcoumarins and 2-phenylbenzofurans
