Twenty two analogues of SB-203207 have been prepared by total synthesis, and evaluated as inhibitors of a range of tRNA synthetases. Changes to the bicyclic core, removing either the terminal amino substituent or the sulfonyl group from the side chain, and altering either the carbon skeleton or stereochemistry of the isoleucine residue, decreases the potency of inhibition of isoleucyl tRNA synthetase. Substituting the isoleucine residue with other amino acids produces inhibitors of the corresponding synthetases. In particular, a methionine derivative is 50-100 times more potent against methionyl tRNA synthetase than against any of the corresponding isoleucyl, leucyl, valyl, alanyl and prolyl synthetases.

Utility of N-acyl mesoionic triazolopyridines as acylating reagents was investigated concerning with peptide synthesis. Several dipeptides and N-alkoxycarbonyl amino acids were prepared by use of these reagents.
