日前,美国化学会药物化学杂志《Jouranl of Medicinal Chemistry》在线发表了中国科学院上海药物研究所杨玉社课题组和嘉兴学院汪海东教授研究组合作的一篇研究论文,论文报道了研究组发现抗多药耐药革兰氏阴性菌候选药物。谭亮和陶匀亮为论文第一作者,杨玉社研究员和嘉兴学院汪海东教授为论文共同通讯作者。

细菌耐药性特别是革兰氏阴性菌的耐药性已成为危害人类健康的重大威胁,目前临床上极度缺乏安全有效的治疗多药耐药革兰氏阴性菌感染的药物,全球范围内处于临床研究的候选药物更是寥寥无几。2017年,世卫组织根据对新型抗生素的迫切需求程度将其分为极为重要、十分重要和中等重要三个类别。列为极为重要的包括耐碳青霉烯类药物的鲍曼不动杆菌(CRA)、绿脓杆菌和产超广谱β-内酰胺酶(ESBLS)肠杆菌科(CRE)三种细菌,均为多药耐药性革兰氏阴性菌。因此研发广谱、强效抗多药耐药革兰氏阴性菌药物是临床上十分迫切的巨大需求。

研发高效抗多药耐药性革兰氏阴性菌药物是世界难题,因为阴性菌耐药机制远比阳性菌复杂多变。革兰氏阴性菌细胞外膜通透性的降低是其产生多药耐药和泛耐药的重要原因,而利用细菌铁载体摄取铁的原理将抗生素与铁载体巧妙地有机结合,是克服革兰氏阴性菌外膜通透障碍的一种有效策略。杨玉社课题组以临床I期的BAL30072为先导化合物,通过结构优化策略,设计合成了一系列铁载体-单环β内酰胺共轭化合物,通过深入的构效关系和构代关系研究,发现了候选化合物12c(如图,YT-14)。YT-14体外对多药耐药性鲍曼不动杆菌(OXA23)、肺炎克雷伯菌(KPC-2)、绿脓杆菌(IMP4)、产超广谱β-内酰胺酶(ESBLS)大肠杆菌均具有很强抑制活性。在多药耐药性肺炎克雷伯菌(KPC-2)感染小鼠模型中,YT-14对小鼠的体内保护作用明显强于BAL30072和美罗培南。总之,YT-14具有强效、广谱抗多药耐药性革兰氏阴性菌活性,代谢性质优良,是一个极具希望的抗革兰氏阴性菌候选化合物,值得进一步研究开发。

Science:想快速形成抗药性?细菌说“容我睡一觉”

近年来,“超级细菌”的事件多有报道。抗生素的未合理使用导致细菌抗药性问题越渐严峻,已经成为全球范围内急需解决的医疗难题。某种程度上讲,抗菌素耐药是一种不可避免的自然过程。但是长期过度使用抗生素、缺乏高质量药物等因素大大加快了这一进程。除了研发更有效的抗菌药物,科学家们还在试图弄清楚细菌抗药性形成的机制。2月9日,《Science》期刊发表文章揭示了细菌抗药性形成的关键机制。当接触多次、高致死量抗生

“超级细菌”抗药性秘密被科学家破解!攻克或指日可待

据外媒报道,“超级细菌”百毒不攻的时代可能行将结束,人类或许已经点住它的命门:它的抗药性的秘密被破解,这就为研发“超级病菌克星”打开了大门。

STM:细胞快照可加速抗生素测试

研究人员研发了一种基于成像的测试来快速、准确地确定细菌对抗生素的敏感性。这种方法可将测试时间从大约16小时减少至4小时,它能有效地帮助医生更加快速地治疗病人,并遏制因为抗生素过度使用和滥用而导致的抗药性——这种情况已经升级并成为一种全球性的健康问题。 当细菌能在有抗生素的情况下繁殖时,它们会被认作对药物有抵抗力,但要检测出这一菌群的生长需要花16-20个小时。为了加快这一过程,Jungi

Science:疟疾药物青蒿素抗药性的分子机制

资料来源: Rick Fairhurst在本期《科学》(Science)杂志中,有两个研究小组报告了新出现的疟疾药物青蒿素抗药性背后的分子机制。由Judith Straimer领导的一个小组证实,疟原虫K13基因中的“推进器突变”造成了该抗药性。由Sachel Mok和同事所撰写的第二份报告对抗药疟疾中的基因表达进行了检查并得出结论:这些突变可帮助疟原虫修复蛋白并延缓其发育。以青蒿素为基础的治疗在

果蝇可能成为抗药性基因散布的帮凶?

滥用抗生素(antibiotics)会加速细菌抗药性的产生,《The Lancet》日前刊登英国卡迪夫大学(Cardiff University)在中国当地进行的最新研究,作者发现在部分地区的养鸡场及医院,抗药性细菌出现频率可能比以往以为的还要高。除此之外,本篇研究亦第一次指出,带有抗药性基因的细菌也可能透过蝇虫(flies)进行传播。黏菌素(Colistin)又称可利斯汀,属于后线抗生素,研究中

美研发新型抗生素teixobactin

研究人员从生活在灰尘中的细菌身上提取出无副作用的抗生素药物,其工作方式使细菌难以产生抗药性。 近日,刊登在国际著名杂志Nature上的一篇研究报告中,来自美国东北大学的研究人员利用一系列技术,成功分离出了一种名为teixobactin的新型抗菌化合物。研究者表示,该化合物杀死小鼠机体中某些细菌的速度与现存抗生素的速度相当,而且无毒副作用,安全有效。最关键的是其并不会诱发细
