Isoprenoid ketones from lipid extracts of tubercle bacilli
Abstract
The isolation of a series of isoprenoid ketones from lipid extracts of human tubercle bacilli is described. The main constituents are shown to have the structure MeC(Me):CH·CH2·[CH2·C(Me):CH·CH2]n·CH2·COMe, where n is 6 and 7, and one of the double bonds is reduced. Further studies indicate that the minor constituents have the above structure with no reduced double bond, and n= 2 to 5.
