The 1-amino group in amikacin was acylated with a variety of 2-hydroxy aminocarboxylic acids to probe the effect of acylation on ribosomal binding and antibacterial activity. The N-hydroxy urea analogue of amikacin (8a) in which the 2-S-hydroxyl-bearing carbon was replaced by an N-OH group was equally active against S. aureus and E. coli in vitro. The analogous tobramycin variant 9 was more active than amikacin. (C) 2003 Elsevier Science Ltd. All rights reserved.
