title: Antibacterial activity of (-)-deoxypseudophrynaminol versus its racemate and derivatives.
abstract: (-)-Deoxypseudophrynaminol 1 possesses 43-fold greater antibacterial potency than the racemate toward Staphylococcus aureus, indicating that the (-)-enantiomer is the biologically active isomer in this assay. Comparison of the percent growth inhibition by derivatives of 1 indicates that prenylation of N8 and replacement of N1-methyl by methyl carbamate are detrimental to antibacterial potency. (-)-1 is a promising lead structure for the development of the novel hexahydropyrrolo[2,3-b]indole class of antibacterial agents.
