  一些新合成的x吨酮的抗幽门螺杆菌活性。

  摘要：

  合成了一系列20种黄嘌呤衍生物，并评估了其抗幽门螺杆菌（H. pylori）的活性。使用Kirby-Bauer方法（琼脂圆盘扩散法）进行了定性和定量体外测试。筛选针对幽门螺杆菌的克拉霉素和/或甲硝唑抗性菌株的测试化合物。作为参考，检查了革兰氏阳性菌（金黄色葡萄球菌）和革兰氏阴性菌（大肠杆菌）。根据微生物学测定，氧杂蒽酮可被认为是潜在的抗H抗体。幽门螺杆菌制剂。它们对所检验的菌株显示出显着的活性，对甲硝唑的抗细菌性比克拉霉素高。对于以下化合物，观察到的最低MIC值高达20 mg l-1：3、4、8、9、12 19（针对甲硝唑抗性菌株）和化合物10（针对克拉霉素抗性菌株）。这些用于筛选an吨酮衍生物的初步结果，是对大量化合物的构效关系进行研究的一部分。随后将进行微生物学测定，以确定氧杂蒽酮对幽门螺杆菌的作用机理。《抗生素杂志》在线提前出版，2016年3月30日；doi：10.1038 / ja

  A series of xanthone derivatives were synthesized and examined for electrocardiographic, antiarrhythmic, hypotensive and anticonvulsant activities as well as for α1- and β1-adrenergic binding affinities. Among the investigated compounds, some of them exhibited significant antiarrhythmic and/or hypotensive activity. The data obtained via receptor binding assay are in agreement with pharmacological results

  A series of 6 derivatives of xanthone were synthesized and evaluated for cardiovascular activity. The following pharmacological experiments were conducted: the binding affinity for adrenoceptors, the influence on the normal electrocardiogram, the effect on the arterial blood pressure, the effect on blood pressor response and prophylactic antiarrhythmic activity in adrenaline induced model of arrhythmia (rats, iv). Two compounds revealed nanomolar affinity for alpha(1)-adrenoceptor which was correlated with the strongest cardiovascular (antiarrhythmic and hypotensive) activity in animals' models. They were enantiomers of previously described (R, S)-4-(2-hydroxy-3-(4-(2-methoxyphenyl)piperazin-1-yl)propoxy)- 9H-xanthen-9-one hydrochloride and revealed similar antiarrhythmic potential in adrenaline induced model of arrhythmia in rats after intravenous injection (ED50 = 0.53 mg/kg and 0.81 mg/kg, respectively). These values were lower than values obtained for reference drug urapidil. These compounds were more active in this experiment than urapidil (ED50 = 1.26 mg/kg). The compound 5 administered iv at doses of 0.62-2.5 mg/kg at the peak of arrhythmia prevented and/or reduced the number of premature ventricular beats in a statistically significant manner. The ED50 value was 1.20 mg/kg. The S-enantiomer (6) given at the same doses did not show therapeutic antiarrhythmic activity in this model.These compounds significantly decreased the systolic and diastolic blood pressure throughout the whole observation period in anesthetized, normotensive rats. The studied enantiomers showed higher toxicity than urapidil, but imperceptibly higher that another cardiovascular drugs, that is, carvedilol or propranolol. They were also evaluated for mutagenic potential in the Ames (Salmonella) test. It was found that at the concentrations tested the compounds were non mutagenic when compared to solvent control.Results were quite promising and suggested that in the group of xanthone derivatives new potential antiarrhythmics and hypotensives might be found.
