Glutamol adenylate 10 was a competitive inhibitor (K(i) = 3 μM) of glutamyl-tRNA synthetase from Escherichia coli. The N6-benzoyl adenine derivative 9 was also an inhibitor (K(i) ~ 60 μM). Replacement of adenine by other bases (purine, cytosine, dihydrocytosine, uridine) resulted in a more than 1000-fold loss in activity, indicating the important contribution of the adenine ring to the enzyme binding.
