title: Antimicrobial activity of diterpene resin acid derivatives.
abstract: C-13 deisopropylated and/or C-7 oxidized resin acid derivatives were tested against various microorganisms to determine structural features responsible for biological activity and to determine the influence of the C-13 isopropyl group on antimicrobial activity. Test results show that methyl cis and trans 7-oxo-13-deisopropyldehydroabietate and a mixture of both isomers exhibited activity against fungi and bacteria.
