摘要:
Three sets of novel 4-deoxy-L-arabinose analogs were synthesized and evaluated as potential inhibitors of the bacterial resistance mechanism in which lipid A, on the outer membrane, is modified with 4-amino-4-deoxy-L-arabinose (L-Ara4N). One compound diminished the transfer of L-Ara4N onto lipid A. These results suggest that small molecules might be designed that would effect the same reversal of bacterial resistance observed in genetic knockouts. (c) 2007 Elsevier Ltd. All rights reserved.
