Racemomycin B is a beta-lysine rich streptothricin antibiotic.
Uses
Racemomycin B (229-B; Streptothricin D), the main component from Streptomyces lavendulae OP-2, is a streptothricin antibiotic containing three β-lysine groups. RM-B exhibits antimicrobial activity against plant pathogenic microorganisms and effectively inhibits the growth of Brassica rapa L. roots at 50 ppm. RM-B showed a minimum inhibitory concentration (MIC) of 0.4 μg/ml against Pseudomonas syringae pv. tabaci IFO-3508 and a MIC range of 0.1-2.0 μg/ml against six strains of Fusarium oxysporum, showing stronger antimicrobial activity than RM-A and RM-C. The biological activity of racemomycin compounds increases with the increase in the number of β-lysine groups.
