摘要: 合成了3-甲基-7--9--10-烃氧基(或芳氧基)-2,3-二氢-7H-吡啶[1,2,3-de]苯并恶嗪-6-羧酸及其类似物, 体外抗菌筛选证明10-烃氧基化合物(尤其是氟乙氧基化合物3d)的抗菌作用明显优于10-羟基化合物3a。体外抗肿瘤试验证明有的化合物对LAXP388细胞株培养具有中等或较低的细胞毒。

Abstract: Some 3-methyl-7-oxo-9-fluoro-10-alkyloxy (or aryloxy)-2, 3-dihydro-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxylic acids and analogues were synthesized. The in vitro antibacterial tests showed that the effect of the 10-alkyloxy compounds (especially the fluoroethyloxycompound 3d) was much better than that of the 10-hydroxy compound 3a. The antitumor test showedthat some target compounds possessed moderate or low cytotoxicity against LAX and P388 in theculture.
