Abstract
本发明提供如(I)式所示噁唑烷酮类化合物及其药学上可接受的盐,式中R=可被取代的芳基磺酰基,可被取代的芳香性杂环磺酰基,可被取代的烷基甲酰基,可被取代的芳基甲酰基,可被取代的芳香性杂环甲酰基。本发明还提供了上述所示化合物的合成方法,及其在作为治疗感染性疾病,尤其是作为治疗多药耐药菌引起的感染性疾病的药物上的应用。
Description
技术领域
本发明涉及药物化学,及化学药物治疗领域。具体涉及噁唑烷酮类化合物的合成,及其在作为治疗感染性疾病的药物上的应用,特别是在作为治疗由多药耐药菌引起的感染性疾病的药物上的应用。
技术背景
抗生素是目前人类治疗细菌感染性疾病的首选药物,然而随着抗生素的广泛使用和存在的不合理滥用问题,越来越多的细菌对抗生素出现耐药性,甚至多药耐药性。比较常见的有耐甲氧西林的金黄色葡萄球菌(MRSA)和表皮葡萄球菌(MRSE)、耐药的肺炎链球菌等,尤其耐万古霉素肠球菌和金黄色葡萄球菌的出现,给细菌感染性疾病的治疗带来了严重问题。
2000年4月,第一个噁唑烷酮类抗感染性药物——利奈唑胺成功上市,它代表了一类新型的全合成的抗细菌感染药物。由于其作用机制不同于目前所有的抗生素和化学合成的抗菌药物,因此减少了交叉耐药的可能性,在治疗一些耐药菌感染性疾病方面疗效显著。目前对噁唑烷酮类抗菌药物的研究主要是提高此类化合物的抗菌活性和拓展其抗菌谱。
本发明的一个目的是提供一类具有抗菌活性特别是对多药耐药菌有效的新型噁唑烷酮类化合物及其药学上可接受的盐。
本发明的另一个目是提供此类化合物及其药学上可接受的盐的合成方法。
本发明的再一个目的是提供此类化合物及其药学上可接受的盐在作为治疗感染性疾病,特别是多药耐药菌引起的感染性疾病的药物上的应用。
发明概述
本发明提供如(I)式所示噁唑烷酮类化合物及其药学上可接受的盐:
式中R=可被取代的芳基磺酰基,可被取代的芳香性杂环磺酰基,可被取代的烷基甲酰基,可被取代的芳基甲酰基,可被取代的芳香性杂环甲酰基。
本发明还提供了上述(I)式所示噁唑烷酮类化合物及其药学可接受盐的合成方法。该合成方法包括以下步骤:
芳香基甲酰胺基乙酸或芳香基磺酰胺基乙酸或烷基甲酰胺基乙酸与二环己基碳化二亚胺(DCC)和S-N-[3-[3-氟-4-(1-哌嗪基)苯基]-2-氧代-5-噁唑烷基]甲基乙酰胺在非质子溶剂中于0-100℃反应1-48h,得到上述所示化合物。
