Photocatalytic and metal-free protocols to access various aromatic and heteroaromatic nitro compounds through ipso-nitration of readily available boronic acid derivatives were developed using non-metal-based, bench-stable, and recyclable nitrating reagents. These methods are operationally simple, mild, regioselective, and possess excellent functional group compatibility, delivering desired products in up to 99% yield.

Paradoxically, some TRPV1 agonists are, at the organismal level, both nonpungent and clinically useful as topical analgesics. Here, we describe the scaled-up synthesis and characterization in mouse models of a novel, nonpungent vanilloid. Potent analgesic activity was observed in models of neuropathic pain, and the compound blocked capsaicin induced allodynia, showing dermal accumulation with little transdermal absorption. Finally, it displayed much weaker systemic toxicity compared to capsaicin and was negative in assays of genotoxicity.

Thymidylate kinase (TMK) is an essential enzyme for DNA synthesis in bacteria, phosphorylating deoxythymidine monophosphate (dTMP) to deoxythymidine diphosphate (dTDP), and thus is a potential new antibacterial drug target. Previously, we have described the first potent and selective inhibitors of Gram-positive TMK, leading to in vivo validation of the target. Here, a structure-guided design approach based on the initial series led to the discovery of novel sulfonylpiperidine inhibitors of TMK. Formation of hydrogen bonds with Arg48 in Staphylococcus aureus TMK was key to obtaining excellent enzyme affinity, as verified by protein crystallography. Replacement of a methylene linker in the series by a sulfonamide was accomplished with retention of binding conformation. Further optimization of log D yielded phenol derivative 11, a potent inhibitor of TMK showing excellent MICs against a broad spectrum of Gram-positive bacteria and >105 selectivity versus the human TMK homologue.
