Abstract:
Considering the anti-infective potential of compounds containing the dibenzothiepine scaffold, we set out to obtain new compounds bearing this structure. The synthesized compounds were characterized by spectral studies and elemental analysis and screened for their microbiostatic/microbicidal and antibiofilm properties against reference and clinical microbial strains. The new compounds exhibited a broad spectrum of antimicrobial activity, which was more intensive for the S-oxidized compounds. Some of the compounds also inhibited the ability of the investigated strains to form biofilms on the inert substratum.
