Abstract

Menaquinone is an obligatory component of the electron-transfer pathway in microorganisms. Its biosynthetic pathway was established by pioneering studies with Escherichia coli and it was revealed to be derived from chorismate by Men enzymes. However, we identified an alternative pathway, the futalosine pathway, operating in some microorganisms including Helicobacter pylori and Campylobacter jejuni, which cause gastric carcinoma and diarrhea, respectively. Because some useful intestinal bacteria, such as lactobacilli, use the canonical pathway, the futalosine pathway is an attractive target for development of chemotherapeutics for the abovementioned pathogens. In this mini-review, we summarize compounds that inhibit Mqn enzymes involved in the futalosine pathway discovered to date.
