One fosmidomycin analog containing an aza‐linker is identified that represents the first herbicide lead structure of new mode of action that targets IspC enzyme in the 2‐C‐methyl‐d‐erythritol 4‐phosphate pathway. Abstract BACKGROUND The enzymes involved in the 2‐C‐methyl‐d‐erythritol 4‐phosphate (MEP) pathway are attractive targets of a new mode of action for developing anti‐infective drugs and herbicides, and inhibitors against 1‐deoxy‐d‐xylulose 5‐phosphate reductoisomerase (IspC), the second key enzyme in the pathway, have be...
