Description

苯并吡喃酮-胺甲基-噁唑烷酮类化合物及其制法和用途
技术领域
本发明涉及胺甲基连接的苯并吡喃酮-噁唑烷酮型化合物的制法以及它们在制备抗菌药物中的应用。
技术背景
耐药细菌的迅速蔓延,使细菌性感染疾病的治疗越来越难。临床研究表明细菌抗药性对几乎所有抗菌药物都构成了威胁,20世纪80年代后期至90年代,革兰氏阴性杆菌如肺炎克雷伯菌和大肠埃希菌产生的超广谱β-内酰胺酶(ESBLs)和诱导性β-内酰胺酶(AmpC酶)可水解包括氧亚氨基类(头抱他啶、头抱曲松、头抱噻肟、氨曲南等)在内的大多数β-内酰胺类抗菌药。多数产ESBLs的菌株为多重耐药株,对氟喹诺酮类药物也具有耐药性。据相关报道氟喹诺酮类药物对肠球菌属、克雷伯氏菌属、大肠埃氏菌、肺炎链球菌等均出现了不同程度的耐药性,同时不同品种间有很高程度的交叉耐药性。
靶点突变是细菌对某种药物产生耐药性的主要途径,单靶点突变的几率是10-7-10-9之间,这一发现表明,若某一药物能作用于多个靶点,那么细菌需用同时在这几个靶点发生突变,才有可能通过靶点突变的途径对这一药物产生耐药性,然而几个靶点同时突变的几率几乎为零,因此多靶点药物是对抗耐药菌有力的武器。基于这一思路,本发明利用骨架迁越原理与计算机辅助药物设计的方法,设计并合成出了能同时作用于S30核糖体亚基和外排泵的胺甲基连接的苯并吡喃酮-噁唑烷酮型化合物,它们既能阻断细菌蛋白质的合成,又能抑制细胞的外排作用,进而提高其在细胞内的浓度,从而提高了对耐药菌的抗菌效果,目前尚无以S30核糖体亚基和外排泵为靶点的多靶点抗菌化合物出现。实验表明,这些结构新颖的抗菌化合物不仅抗耐药菌效果突出而且安全性好。

外排率越低,化合物对外排泵的抑制越好,结果见表2。

结果表明,化合物2、5、14、28、46、48、63、86对所测试的菌均具有显著的抑制作用。2、5、14、22、28、46、48、57、63、68、77、86、94对表皮葡萄球菌表现出优良的抗菌活性,2、5、8、14、28、32、36、41、46、48、55、59、63、72、86、91对肺炎克雷伯菌表现优良的抗菌活性,它们的抗菌活性超过了青霉素G和卡拉霉素;2、5、14、28、36、46、48、61、63、66、74、86、96对新型隐球菌表现优良的抗菌活性,抗真菌活性超过了阳性对照酮康唑。化合物2、5、14、28、36、46、48、63、74、86不仅有较好的抗菌活性而且对核糖体介导的蛋白质合成和外排泵均起到了有效的抑制作用,证明是多靶点抗菌化合物。
本发明的上述实施例表明:在合成的胺甲基连接的苯并吡喃酮-噁唑烷酮型化合物中,一部分的抗菌活性高于阳性对照物青霉素G、卡拉霉素或酮康唑。对大鼠的急毒实验表明,化合物2、14、46、63的剂量达到5g/kg(此剂量为药典规定的无毒剂量)时,没有发现大鼠有中毒迹象,因此在正常剂量下,它们作为药物应用是安全的。
