title: Synthesis of new 2-substituted-[1,3,4]-oxadiazino-[6,5-b]-indoles with H1-antihistaminic, antimuscarinic and antimicrobial activity [corrected].
abstract: New 2-substituted-[1,3,4]-oxadiazino-[5,6-b]-indoles have been prepared and tested for their antibacterial, antifungal, H1-antihistaminic and antimuscarinic activities. Among them, compounds 5b, 5d, 5k exhibited higher H1-antihistaminic activity than pheniramine maleate. Compounds 5c, 5d showed higher antibacterial activity than ampicillin against Staphylococcus aureus and E. coli, respectively.
