通过美国国立卫生研究院的两个项目,对大型商业可用文库进行高通量表型筛选,已经产生了数千种潜在的有趣的靶向药物,可以作为抗结核药物进一步开发。不幸的是,这些筛选不能提供靶点信息,需要进一步跟踪靶点识别,以实现最佳合理设计和开发高度活跃和选择性的临床候选药物。从这些HTS筛选中对喹啉和喹唑啉的化学信息学分析表明,这两类化合物中的某些化合物可能靶向分枝杆菌微管蛋白同源物FtsZ。在这篇简短的通讯中,证实了一种喹啉铅对Mtb靶靶FtsZ的活性,以及对Mtb H37Rv良好的体外全细胞抗菌活性。这种高度可处理的药效团的假设靶标的确定将有助于对FtsZ和细胞分裂感兴趣的药物化学家制定合理的设计方案,以优化这种活性,从而获得一种新的候选药物。
High throughput phenotypic screening of large commercially available libraries through two NIH programs has produced thousands of potentially interesting hits for further development as antitubercular agents. Unfortunately, these screens do not supply target information, and further follow up target identification is required to allow optimal rational design and development of highly active and selective clinical candidates. Cheminformatic analysis of the quinoline and quinazoline hits from these HTS screens suggested a hypothesis that certain compounds in these two classes may target the mycobacterial tubulin homolog, FtsZ. In this brief communication, activity of a lead quinoline against the target FtsZ from M. tuberculosis (Mtb) is confirmed as well as good in vitro whole cell antibacterial activity against Mtb H37Rv. The identification of a putative target of this highly tractable pharmacophore should help medicinal chemists interested in targeting FtsZ and cell division develop a rational design program to optimize this activity towards a novel drug candidate.
