Attachment of a 5-nitrofuroyl moiety to spirocyclic piperidines produces non-toxic nitrofurans that are efficacious in vitro against multidrug-resistant Mycobacterium tuberculosis
belonging to the nitrofuran class of antimicrobials has been developed via conjugation of the nitrofuran moiety to a series of spirocyclic piperidines through an amide linkage. It proved to have comparable activityagainst drug-sensitive (H37Rv) strain as well as multidrug-resistant, patient-derived strains of Mycobacteriumtuberculosis. The compound is druglike, showed no appreciable cytotoxicity toward
