  摘要：

  This paper reports the synthesis of a series of new 5-substituted-1-(2-hydroxybenzoyl)-benzotriazoles, which have been tested for their activity as possible activators of potassium channels. In rat aortic rings, the 'opened' derivatives 1a-f, intermediates of synthesis, showed vasorelaxing properties, with appreciable values of potency. However, the most remarkable effects were recorded for the 2-hydroxybenzoylbenzotriazoles 3a-f, which showed full vasorelaxing efficacy and high potency values. The introduction of a 2-hydroxybenzyl substituent in the 1 position of the benzotriazole ring (compound 7) strongly decreased the activity, showing the importance of the electron-acceptor carbonyl function. The best compound, 3b, was further investigated, in order to evaluate the possible mechanism of action involved in the vasodilator activity. In the vascular model, different potassium channel blockers inhibited the effects of the compound, and an increase of the levels of membrane depolarisation induced a significant reduction of the recorded responses. Compound 3b was also tested in a model of isolated rat heart, retroperfused through the aorta and submitted to a global ischemia/reperfusion cycle. In such an experimental condition, 3b showed an interesting cardioprotective activity. All the above observations are in agreement with the hypothesis of a mechanism linked to the activation of potassium channels. (C) 2001 Elsevier Science S.A. All rights reserved.

  vancomycin-resistant Staphylococcus aureus (VRSA) are primary causes of skin and soft tissue infections worldwide. To address the emergency caused due to increasing multidrug-resistant (MDR) bacterial infections, a series of novel fluoro and trifluoromethyl-substituted salicylanilide derivatives were synthesized and their antimicrobial activity was investigated. MIC data reveal that the compounds inhibited S. aureus

  耐甲氧西林金黄色葡萄球菌(MRSA) 和耐万古霉素金黄色葡萄球菌(VRSA) 是全球皮肤和软组织感染的主要原因。为解决由于多重耐药 (MDR) 细菌感染引起的紧急情况，合成了一系列新型氟和三氟甲基取代的水杨酰苯胺衍生物，并对其抗菌活性进行了研究。MIC 数据显示，这些化合物特异性抑制金黄色葡萄球菌（MIC 0.25–64 µg/mL）。MIC < 1 µg/mL的化合物对 Vero 细胞的体外细胞毒性导致鉴定出四种化合物（20、22、24和25 ）)，选择性指数高于 10。这四种化合物针对 MDR S. aureus小组进行了测试。值得注意的是，5-氯-N- (4'-溴-3'-三氟甲基苯基)-2-羟基苯甲酰胺 ( 22 ) 对 9 种 MRSA 和 3 种 VRSA 菌株表现出优异的活性，MIC 为 0.031–0.062 µg/mL，显着优于对照药物甲氧西林和万古霉素。比较时间-杀灭动力
