  Synthesis and Antibacterial Activity of Novel Pyridobenzoxazine Analogues.

  摘要：

  研究人员合成了一系列新型 LVFX (7) 类似物，这些类似物在吡啶并噁嗪的 C-10 位上含有 4，4-二烷基-3-氨基吡咯烷，并评估了它们在动物体内的抗菌活性、药代动力学和急性毒性。非烷基化吡咯烷衍生物 26a 对包括铜绿假单胞菌在内的革兰氏阳性菌和革兰氏阴性菌的活性高于 LVFX（7），但 26a 对小鼠具有较高的急性毒性，对大鼠的药代动力学也不理想。与 26a 相比，4,4-二烷基化衍生物 26c、e、g 对革兰氏阳性菌具有更强的活性，同时还改善了药代动力学，降低了急性毒性。通过在吡咯烷环上进行烷基化来增加亲脂性，对上述特性产生了良好的影响。

  Methods and compositions comprising chemical compounds that modulate the silencing of a polynucleotide of interest in a cell are provided. Such chemical compounds when used in combination with an appropriate silencing element can be used to modulate (increase or decrease) the level of the polynucleotide targeted by the silencing element. Methods of using such compositions both in therapies involving RNAi-mediated suppression of gene expression, as well as, in vitro methods that allow for the targeted modulation of expression of a polynucleotide of interest are provided. Pharmaceutical or cosmetic formulations comprising such compounds and silencing elements also are disclosed. Methods for screening a compound of interest for the ability to modulate the activity of a heterologous silencing element also are provided.

  A series of novel LVFX (7) analogues bearing 4, 4-dialkyl-3-aminopyrrolidines at the C-10 position of pyridobenzoxazine was synthesized and their antibacterial activities, pharmacokinetics and acute toxicities in animals were evaluated. Non-alkylated pyrrolidine derivative 26a showed greater activity than LVFX (7) against gram-positive and gram-negative bacteria including Pseudomonas aeruginosa, but 26a possessed high acute toxicity in mice and unfavorable pharmacokinetics in rats. When compared with 26a, 4, 4-dialkylated derivatives 26c, e, g showed more potent activity against gram-positive bacteria along with an improvement of pharmacokinetics and reduction of acute toxicity. Increases in lipophilicity by alkylation on the pyrrolidine ring resulted in a good influence on the above profiles.
