Synthesis and in vitro antibacterial activity of gemifloxacin derivatives containing a substituted benzyloxime moiety
摘要:
A series of novel gemifloxacin (GMFX) derivatives containing a substituted benzyloxime moiety with remarkable improvement in lipophilicity were synthesized. The target compounds evaluated for their in vitro antibacterial activity against representative strains. Our results reveal that most of the target compounds have considerable potency against all of the tested Gram-positive strains including MRSA and MRSE (MIC: <0.008-8 mu g/mL), although they are generally less active than the references against the Gram-negative strains. In particular, compound 111 (MIC: <0.008-4 mu g/mL) was found to be 8-2048 and 2-128 times more potent than levofloxacin (LVFX) and GMFX against the Gram-positive strains, respectively. Moreover, against MRSA clinical isolates, 111 (MIC90: 1 mu g/mL) is 8-fold more active than GMFX, and 2-fold more active than GMFX and moxifloxacin against MRSE clinical isolates (MIC90: 4 mu g/mL).

Guanidine Derivatives: How Simple Structural Modification of Histamine H<sub>3</sub>R Antagonists Has Led to the Discovery of Potent Muscarinic M<sub>2</sub>R/M<sub>4</sub>R Antagonists
muscarinic receptor antagonists identified during a search for more active histamine H3 receptor (H3R) ligands. The idea was to replace the flexible seven methylene linker with a semirigid 1,4-cyclohexylene or p-phenylene substituted group of the previously described histamine H3R antagonists ADS1017 and ADS1020. These simple structural modifications of the histamine H3R antagonist led to the emergence
本文介绍了在寻找更活跃的组胺 H 3受体 (H 3 R) 配体期间发现的新型强效毒蕈碱受体拮抗剂。该想法是用先前描述的组胺 H 3 R 拮抗剂ADS1017和ADS1020的半刚性 1,4-亚环己基或对亚苯基取代基团替换柔性七亚甲基接头。组胺 H 3 的这些简单结构修饰R 拮抗剂导致出现额外的药理作用,其中一些出人意料地显示出对毒蕈碱受体的强拮抗剂效力。本文报告了胍衍生物的合成路线和药理学表征,这是一种新型化学型毒蕈碱受体拮抗剂,可在纳摩尔浓度范围内与人类毒蕈碱 M 2和 M 4受体(分别为 hM 2 R 和 hM 4 R)结合。新合成的ADS10227(1-4-4-[4-(苯氧基甲基)环己基]甲基}哌嗪-1-基}but-1-yl}-1-(苄基)胍)在 hM 2处的亲和力R 和 hM 4 R 分别为 2.8 nM 和 5.1 nM。

described indole-containing compounds with the potential to inhibitHIV-1fusion by targeting the hydrophobic pocket of transmembrane glycoprotein gp41. Here we report optimization and structure–activity relationship studies on the basic scaffold, defining the role of shape, contact surface area, and molecular properties. Thirty new compounds were evaluated in binding, cell–cell fusion, and viral replication
