the most efficacious derivative (IC50 = 2.56 ± 0.07 μM for NCI-H1299 and IC50 = 13.69 ± 0.70 μM for A549, respectively) that inhibited the proliferation of NCI-H1299 cells. Of these, Compound 4b (1 – cyclopropyl – 6 – fluoro – 8 – methoxy – 4 – oxo – 7 – ((4aS,7aS) – 1 – (2 – oxo – 2 – (p – tolylamino) ethyl) hexahydro – 1H – pyrrolo [3,4-b] pyridine – 6(2H)-yl) – 1,4 – dihydroquinoline – 3-carboxylic
通过对N-5-Aza环进行功能修饰,合成了八种新颖的莫西沙星(MXF)衍生物4a-h。通过MTT比色测定评估它们对人非小肺癌细胞NCI-H1299和A549的生长抑制活性。基于所述半抑制浓度(IC 50)值,我们确定化合物4b中是最有效的衍生物(IC 50 = 2.56±0.07μM为NCI-H1299和IC 50 即抑制= 13.69±0.70分别μM为A549,) NCI-H1299细胞的增殖。其中,化合物4b(1 –环丙基– 6 –氟– 8 –甲氧基– 4 –氧代– 7 –(((4aS,7aS)– 1 –(2 –氧代– 2 –(p –甲苯基)乙基))六氢– 1H –吡咯[3, 4-b]吡啶– 6(2H)-基)– 1,4 –二氢喹啉– 3-羧酸)对NCI-H1299细胞的生长表现出良好的效能,对HUVEC细胞具有选择性(IC 50 > 500μM)。通过AO / EB荧光染色证实了
