  摘要：

  摘要 合成了恶唑烷酮异羟肟酸衍生物，并在三个体外基于细胞的测试系统中评估了对白三烯（LT）生物合成的抑制活性，并直接抑制了重组人5-脂氧合酶（5-LO）。合成的19种化合物中有13种被认为具有活性（（在两个或多个测试系统中，50％抑制浓度（IC 50）≤10 µM））。异羟肟酸部分上烷基链长度的增加增强了活性，并且含有吗啉基的衍生物比N-乙酰基-哌嗪基衍生物更具活性。IC 50基于细胞的测定系统中的值与通过直接抑制5-LO活性获得的值相当，这证实了这些化合物是5-LO的直接抑制剂。尤其是，化合物PH-249和PH-251具有出色的效力（IC 50 <1 µM），与原型5-LO抑制剂齐留通的效价相当。发音的体内活性证实在小鼠酵母聚糖诱导的腹膜炎。因此，这些新颖的恶唑烷酮异羟肟酸衍生物是有效的5-LO抑制剂，具有潜在的抗过敏和消炎作用。

  Synthesis and biological evaluation of novel 5-(hydroxamic acid)methyl oxazolidinone derivatives

  摘要：

  Research activities on the oxazolidinone antibacterial class of compounds continue to focus on developing newer derivatives with improved potency, broad-spectrum activity and safety profiles superior to linezolid. Among the safety concerns with the oxazolidinone antibacterial agents is inhibition of monoamine oxidases (MAO) resulting from their structural similarity with toloxatone, a known MAO inhibitor. Diverse substitution patterns at the C-5 position of the oxazolidinone ring have been shown to significantly affect both antibacterial activity and MAO inhibition to varying degrees. Also, the antibacterial activity of compounds containing iron-chelating functionalities, such as the hydroxamic acids, 8-hydroxyquinolines and catechols have been correlated to their ability to alter iron intake and/or metabolism. Hence a series of novel 5-(hydroxamic acid)methyl oxazolidinone derivatives were synthesized and evaluated for their antibacterial and MAO-A and -B inhibitory activities. The compounds were devoid of significant antibacterial activity but most demonstrated moderate MAO-A and -B inhibitory activities. Computer modeling studies revealed that the lack of potent antibacterial activity was due to significant steric interaction between the hydroxamic acid N-OH oxygen atom and one of the G2540 5'-phosphate oxygen atoms at the bacterial ribosomal binding site. Therefore, the replacement of the 5-acetamidomethyl group of linezolid with the 5-(N-hydroxyacetamido)methyl group present in the hydroxamic acid oxazolidinone derivatives was concluded to be detrimental to antibacterial activity. Furthermore, the 5-(hydroxamic acid)methyl oxazolidinone derivatives were also less active as MAO-A and -B inhibitors compared with linezolid and the selective inhibitors clorgyline and pargyline. In general, the 5-(hydroxamic acid)methyl oxazolidinone derivatives demonstrated moderate but selective MAO-B inhibitory activity. (C) 2015 Elsevier Masson SAS. All rights reserved.

  A series of 5-substituted oxazolidinones with varying substitution at the 5-position of the oxazolidinone ring were synthesized and their in vitro antibacterial activity was evaluated. The compounds demonstrated potent to weak antibacterial activity. A novel compound (PH-027) demonstrated potent antibacterial activity, which is comparable to or better than those of linezolid and vancomycin against
