(-)-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.
(-)-脱氧假蟾蜍胺醇1对金黄色葡萄球菌的抗菌效力比外消旋体高43倍,这表明(-)-对映体是该测定中的生物活性异构体。1的衍生物对生长抑制百分比的比较表明,N8的异戊烯基化和用氨基甲酸甲酯取代N1-甲基对抗菌效力不利。(-)-1是开发新型六氢吡咯并[2,3-b]吲哚类抗菌剂的有前景的先导结构。
