Patent number: 8461128Abstract: Many pathogens, including Mycobacterium tuberculosis and Yersinia pestis, rely on an iron acquisition system based on siderophores, secreted iron-chelating compounds with extremely high Fe(III) affinity. The compounds of the invention are inhibitors of domain salicylation enzymes, which catalyze the salicylation of an aroyl carrier protein (ArCP) domain to form a salicyl-ArCP domain thioester intermediate via a two-step reaction. The compounds include the intermediate mimic 5?-O—[N-(salicyl)sulfamoyl]-adenosine (salicyl-AMS) and analogs thereof. These compounds are inhibitors of the salicylate activity of MbtA, YbtE, PchD, and other domain salicylation enzymes involved in the biosynthesis of siderophores. Therefore, these compounds may be used in the treatment of infection caused by microorganisms which rely on siderphore-based iron acquisition systems.Type: GrantFiled: April 14, 2006Date of Patent: June 11, 2013Assignees: Sloan-Kettering Institute for Cancer Research, Cornell Research Foundation, Inc.Inventors: Derek Shieh Tan, Luis E.
