title: Pyrazino[1,2-a]indole-1,4-diones, simple analogues of gliotoxin, as selective inhibitors of geranylgeranyltransferase I.
abstract: Some pyrazino[1,2-a]indole-1,4-diones, structurally simplified analogues of the natural mycotoxin gliotoxin, have been synthesised and investigated as inhibitors of prenyltransferases; one compound, 3-acetylthio-9-methoxy-2-methyl-2,3-dihydropyrazino[1,2-a]indole-1,4-dione 10 shows slightly greater selectivity (8-fold) for geranylgeranyltransferase type I (GGTase I) than gliotoxin itself.
