- 1,3-Dioxane-Linked Bacterial Topoisomerase Inhibitors with Enhanced Antibacterial Activity and Reduced hERG Inhibition
-
The development of new therapies to treat methicillin-resistant Staphylococcus aureus (MRSA) is needed to counteract the significant threat that MRSA presents to human health. Novel inhibitors of DNA gyrase and topoisomerase IV (TopoIV) constitute one highly promising approach, but continued optimization is required to realize the full potential of this class of antibiotics. Herein, we report further studies on a series of dioxane-linked derivatives, demonstrating improved antistaphylococcal activity and reduced hERG inhibition. A subseries of analogues also possesses enhanced inhibition of the secondary target, TopoIV.

- A one-pot diazotation-fluorodediazoniation reaction and fluorine gas for the production of fluoronaphthyridines
-
Several synthetic routes to 7-fluoro-2-methoxy-8-methyl-1,5-naphthyridine (1) are presented, and their suitability for scale-up is discussed. The way of introducing the fluorine atom is crucial. Early routes start from commercially available fluorinated building blocks or employ F+ reagents like SelectFluor and delivered up to 70 kg of 7-fluoro-2-methoxy-1,5-naphthyridine (18). To prepare for larger scales, the focus turned to the use of HF or elemental fluorine, both one of the cheapest sources of fluorine. The first method, a one-pot diazotation-fluorodediazoniation with 6-methoxy-1,5- naphthyridin-3-amine (9) in HF gave the fluorinated naphthyridine 18 in high yield and purity without isolation of the unstable diazonium salt, the latter being a severe drawback of the related Balz-Schiemann protocol. The second method relies on the use of fluorine gas for a surprisingly selective ortho-fluorination of 6-methoxy-1,5-naphthyridin-4-ol (10).
