The aminoacyl-beta-ketophosphonate-adenosines (aa-KPA) are stable analogs of the aminoacyl adenylates, which are high-energy intermediates in the formation of aminoacyl-tRNA catalyzed by aminoacyl-tRNA synthetases (aaRS). We have synthesized glutamyl-beta-ketophosphonate-adenosine (Glu-KPA) and glutaminyl-beta-ketophosphonate-adenosine (Gln-KPA), and have tested them as inhibitors of their
