Abstract: High Resolution Image Download MS PowerPoint Slide In the search for new antitubercular compounds, we leveraged target-directed dynamic combinatorial chemistry (tdDCC) as an efficient hit-identification method. In tdDCC, the target selects its own binders from a dynamic library generated in situ, reducing the number of compounds that require synthesis and evaluation. We combined a total of 12 hydrazides and six aldehydes to generate 72 structurally diverse N -acylhydrazones. To amplify the best binders, we employed anti-infective target 4-diphosphocytidyl-2 C -methyl- d -erythritol kinase (IspE) from Mycobacterium tuberculosis ( Mtb ). We successfully validated the use of tdDCC as hit-identification method for IspE and optimized the analysis of tdDCC hit determination. From the 72 possible N -acylhydrazones, we synthesized 12 of them, revealing several new starting points for the development of IspE inhibitors as antibacterial agents.
