ABSTRACT
Mycobacterium tuberculosis
is a global pathogen of huge importance which can adapt to several host niche environments in which carbon source availability is likely to vary. We developed and ran a phenotypic screen using butyrate as the sole carbon source to be more reflective of the host lung environment. We screened a library of ∼87,000 small compounds and identified compounds which demonstrated good antitubercular activity against
M. tuberculosis
grown with butyrate but not with glucose as the carbon source. Among the hits, we identified an oxadiazole series (six compounds) which had specific activity against
M. tuberculosis
but which lacked cytotoxicity against mammalian cells.
摘要
结核分枝杆菌
是一种全球性的重要病原体,它能适应多种宿主生态位环境,而在这些环境中,碳源的可用性可能会有所不同。为了更好地反映宿主肺部环境,我们开发并运行了一个以丁酸盐为唯一碳源的表型筛选。我们筛选了一个包含 ∼87,000 个小化合物的化合物库,并确定了对结核杆菌具有良好抗结核活性的化合物。
结核杆菌
的抗结核活性。在这些新发现的化合物中,我们发现了一个恶二唑系列(6 个化合物),它们对结核杆菌具有特异性活性。
结核杆菌
但对哺乳动物细胞缺乏细胞毒性。
