value. We describe a novel class of N-linked aminopiperidinyl alkyl quinolones and naphthyridones that kills Mtb by inhibiting the DNA gyrase activity. The mechanism of inhibition of DNA gyrase was distinct from the fluoroquinolones, as shown by their ability to inhibit the growth of fluoroquinolone-resistant Mtb. Biochemical studies demonstrated this class to exert its action via single-strand cleavage

A number of non-canonical amino acids (NCAAs) with unstrained olefins are genetically encoded using mutant pyrrolysyl-tRNA synthetase–tRNAPylCUA pairs for catalyst-free labeling with tetrazine dyes.

2′-Fluorinated Northern methanocarbacyclic (2′-F-NMC) nucleosides and phosphoramidites, based on a bicyclo[3.1.0]hexane scaffold bearing all four natural nucleobases (U, C, A, and G), were synthesized to enable exploration of this novel nucleotide modification related to the clinically validated 2′-deoxy-2′-fluororibonucleotides (2′-F-RNA).

of evaluation of carbocyclic ribonucleoside-containing oligonucleotide therapeutics, we developed convenient, scalable syntheses of all four carbocyclic ribonucleotide phosphoramidites and the uridine solid-support building block. Crystallographic analysis confirmed configuration and stereochemistry of these building blocks. Duplexes with carbocyclic RNA (car-RNA) modifications in one strand were less
