美國威斯康星大學麥迪遜分校Tim S. Bugni和David R. Andes研究小組合作取得一項新成果。他們發現從海洋微生物提取的抗真菌藥可殺傷高威脅性耐藥真菌。相關論文於2020年11月20日發表於國際學術期刊《科學》。
利用海洋動物微生物群以及先進代謝組學和基因組學相結合的方法,研究人員發現了具有體內功效的抗真菌分子。最有成藥潛能的是turbinmicin,其對多種耐藥性真菌病原體顯示出有效的體外和小鼠模型功效,並具有廣泛的安全指數,其通過針對囊泡運輸途徑Sec14的真菌特異性作用方式發揮功能。與其他抗真菌藥不同的功效、安全性和作用方式,使的turbinmicin成為一種很有潛能的抗真菌藥,可幫助解決毀滅性的全球真菌病原體,例如耳念珠菌。
據介紹,迫切需要新的抗真菌藥物來解決真菌感染性疾病(如泛耐藥性耳念珠菌)的發生和跨地區性傳播。

Abstract: New antifungal drugs are urgently needed to address the emergence and transcontinental spread of fungal infectious diseases, such as pandrug-resistant Candida auris. Leveraging the microbiomes of marine animals and cutting-edge metabolomics and genomic tools, we identified encouraging lead antifungal molecules with in vivo efficacy. The most promising lead, turbinmicin, displays potent in vitro and mouse-model efficacy toward multiple-drug–resistant fungal pathogens, exhibits a wide safety index, and functions through a fungal-specific mode of action, targeting Sec14 of the vesicular trafficking pathway. The efficacy, safety, and mode of action distinct from other antifungal drugs make turbinmicin a highly promising antifungal drug lead to help address devastating global fungal pathogens such as C. auris.
