Syntheses, in vitro antibacterial and antifungal activities of a series of N-alkyl, 1,4-dithiines

Article abstract of DOI:10.1016/j.farmac.2005.06.015

A series of dithiines were synthesized by cyclization of 4-(alkylamino)-4-oxobutanoic acids under the action of SOCl₂. Their in vitro antibacterial and antifungal activities have been evaluated against reference strains and versus reference compounds. The so-called 'isoimides' 2a, 2b were totally inactive whereas some imides had low MICs for few bacteria and for few fungal microorganisms.
