摘要

The invention provides compounds and salts of Formula I and Formula II which possess antimicrobial activity. The invention also provides novel synthetic intermediates useful in making compounds of Formula I and Formula II. The variables n, m, p, RA, RB, A1, R2, R3, R5, R6, R7, A8 and R9 are defined herein. Certain compounds of Formula I and Formula II disclosed herein are potent and /or selective inhibitors of bacterial replication. The invention also provides antimicrobial compositions, including pharmaceutical compositions, containing one or more compounds of Formula I or Formula II an d one or more carriers, excipients, or diluents. Such compositions may contain a compound of Formula I or Formula II as the only active agent or may contain a combination of a compound of Formula I or Formula II and one or more other active agents. The invention also provides methods for treating microbial infections in eukaryotes.
