    摘要:
    迫切需要具有新颖靶标和作用机理的新型抗菌剂,以解决有问题的细菌感染和增加抗生素耐药性。拓扑异构酶IA代表了一个有吸引力的且尚未开发的抗菌靶标,因此,人们越来越有兴趣开发用于抗菌治疗的选择性和有效的拓扑异构酶I抑制剂。根据我们的初步生物学筛选,发现氟喹啉吩恶嗪1是一种针对大肠杆菌的低微摩尔抑制剂。拓扑异构酶IA。在文献中,已经研究了氟喹啉吩恶嗪类似物作为抗菌剂和抗癌剂,但是,它们对拓扑异构酶I的抑制作用尚未得到充分开发,并且几乎没有可用的结构活性关系(SAR)。良好的1对拓扑异构酶I抑制活性和SAR的缺乏促使我们设计和合成了一系列氟喹吩恶嗪类似物,以系统地评估SAR,并探查了氟喹吩恶嗪核心对拓扑异构酶I酶靶识别的结构元素。在这项研究中,设计,合成和评估了一系列氟喹啉吩恶嗪类似物,作为拓扑异构酶I抑制剂和抗菌剂。基于靶标的测定表明,氟喹啉恶嗪衍生物具有9-NH2和/或6-取代的胺官能团通常表现

    公开(公告)日:1996-05-28
    A process to obtain benzoxazines useful for the synthesis of Ofloxazine, Levofloxazine and derivatives. The benzoxacines (I) where Xb is an halogen and R.sub.1 is H, alkyl or alkenyl of up to 6 atoms of C or aryl, can be obtained by means of cycling a compound of formula (II) through the reaction with triphenylphosphine and ethyl azodicarboxilate. The compounds of formula (II) can be obtained through the reaction of a compound (III) with an adequate epoxide. Through the use of the adequate chiral epoxide it is possible to obtain the enantiomerically desired intermediate and, therefore and selectively, it is possible to obtain the desired final product with the adequate enantiomeric form without the need to carry out a resolution stage. The Compounds (I) are useful and key intermediates for the synthesis of the antimicrobials Oflixazine and Levofloxazine. ##STR1##
    一种用于合成Ofloxazine、Levofloxazine和衍生物的苯并噁嗪的方法。苯并噁嗪(I)中Xb为卤素,R.sub.1为H、烷基或最多6个碳原子的烯基或芳基,可通过将式(II)的化合物与三苯基膦和乙基叠氮二羧酸乙酯反应而获得。式(II)的化合物可通过将化合物(III)与适当的环氧化物反应而获得。通过使用适当的手性环氧化物,可以获得所需的对映异构体中间体,因此可以选择性地获得所需的最终产物,而无需进行分离阶段。化合物(I)是合成抗菌药Oflixazine和Levofloxazine的有用且关键的中间体。
