A series of eperezolidanalogs with glycinylsubstitutions were prepared and their antibacterialactivities were studied against a panel of susceptible and resistant Gram‐positive bacteria. The compounds with N‐arylacyl or N‐heteroarylacyl glycinyl structural units showed good antibacterialactivities. The compounds 11b, 11c, and 11e were twofold more active than linezolid against Staphylococcus epidermidis
制备了一系列具有甘氨酰基取代的 eperezolid 类似物,并研究了它们对一组敏感和耐药革兰氏阳性细菌的抗菌活性。具有N-芳酰基或N-杂芳酰基甘氨酰基结构单元的化合物表现出良好的抗菌活性。化合物 11b、11c 和 11e 对表皮葡萄球菌和粪肠球菌的活性是利奈唑胺的两倍。还制备了几种吡啶类似物,发现对大多数测试的革兰氏阳性细菌的抗菌活性较差,但是,其中一种化合物 12e 对粪肠球菌表现出非常高的活性。

MOR antagonist mainly acting within the peripheral nervous system. The noticeable diarrhea associated with it prompted the design and synthesis of its analogues in order to study its structure–activity relationship. Among them, compound 8 showed improved pharmacological profiles compared to the original lead, acting mainly at peripheral while increasing the intestinal motility in morphine-pelleted mice
外周选择性μ阿片受体(MOR)拮抗剂可以减轻阿片类药物引起的便秘(OIC)的症状,而不会影响阿片类药物的镇痛作用。然而,与它们相关的各种不利影响,部分是由于它们相对较低的 MOR 选择性。NAP 是一种6β- N -4'-吡啶基取代的纳曲胺衍生物,以前被鉴定为主要作用于外周神经系统的有效且高度选择性的 MOR 拮抗剂。与之相关的明显腹泻促使设计和合成其类似物以研究其结构-活性关系。其中,化合物8与原始铅相比,显示出改善的药理学特征,主要作用于外周,同时增加吗啡颗粒小鼠的肠蠕动(ED 50 = 0.03 mg/kg)。与原始铅相比,ED 50的轻微下降被未观察到的不利影响很好地补偿了。因此,该化合物似乎是开发针对 OIC 的新型治疗剂的更有希望的线索。

Selective, non-peptide antagonists of the mu opioid receptor (MOR) and methods of their use are provided. The antagonists may be used, for example, to identify MOR agonists in competitive binding assays, and to treat conditions related to addiction in which MOR is involved, e.g. heroin, prescription drug and alcohol addiction, as well as in the treatment of opioid induced constipation (OIC).
