作为研究计划的一部分,制备了咪唑并[1,5-g] [1,4]二氮杂derivatives衍生物7a和7b,它们是没有芳香环的TIBO类似物,目的是寻找对HIV-2具有抗病毒活性和抗药性的菌株。 HIV-1。N-三苯甲基和N-甲苯磺酰基4-(2-氯乙基)-咪唑与适当的氨基醇的缩合得到化合物10a-c和16a-e。这些中间体中的羟基通过转化为相应的氯衍生物或通过甲苯磺酰基的N→O转移而被激活,从而使[1,4]二氮杂卓环闭合。然而,仅环化至化合物13a和13b被证明是有效的。这些产物被转化为目标分子7通过它们的C-2阴离子与S 8反应。化合物7a,b和13a,b在细胞培养物中的体外评估(CEM SS / HIV-1-LAI和CEM SS / HIV 1 nevirapine抗性细胞)显示只有13b表现出最小的活性。

kyl]imidazole isosteres (where X = NH, S, CH2S, O) of previously described [[(5-nitropyrid-2-yl)X]ethyl]imidazoles (where X = NH, S) have been synthesized and evaluated for H3-receptor histamine antagonism in vitro (Ki for [3H]histamine release from rat cerebral cortex synaptosomes) and in vivo (ED50 per os in mice on brain tele-methylhistamine levels). Encouraging results led to the synthesis and

Para‐substituted aromatic ethers with benzophenone or related structural elements and a 3‐(1H‐imidazol‐4‐yl)propyloxy moiety were prepared by Mitsunobu‐type ether synthesis or SNAr reaction. Most of the title compounds possess high antagonist potency in histamine H3‐receptor assays in vitro as well as in vivo in mouse CNS following oral administration. After defining 4‐(3‐(1H‐imidazol‐4‐yl)propyloxy)phenyl

The emergence of multidrug resistant (MDR) Gram-negative bacterial pathogens has raised global concern. Nontraditional therapeutic strategies, including antivirulence approaches, are gaining traction as a means of applying less selective pressure for resistance in vivo. Here, we show that rigidifying the structure of the siderophore preacinetobactin from MDR Acinetobacter baumannii via oxidation of
