AI 77B Usage And Synthesis
Description
AI 77B is a pseudopeptide microbial agent with gastroprotective action.
Uses
Amicoumacin B can be produced by actinomycete, strain 04-5195T.. Amicoumacin B increases the expression of bone morphogenetic protein 2 (BMP-2). Amicoumacin B has inhibitory effect against C. violaceum (MIC = 250 μg/mL). Amicoumacin B has quorum sensing inhibitory activity, and reduces the expression of the C. violaceum operons vioA, vioB, vioD, and vioE, but increases the expression of vioC[1][2].
