inhibition observed at 10 to 30 micro M. Growth was rescued by increasing the SPase levels. The cell-based assay was used to test cellular inhibition of SPase by compounds that inhibit the enzyme in vitro. MD1, MD2, and MD3 are SPase inhibitors with antimicrobial activity against Staphylococcusaureus, although they do not inhibit growth of E. coli. MD1 presented the best spectrum of antimicrobial activity
