A new series of FTase inhibitors containing a tricyclic moiety-dioxodibenzothiazepine or dibenzocycloheptane-has been designed and synthesized. Among them, dioxodibenzothiazepine 18d displayed significant inhibitory FTase activity (IC50 = 17.3 nM) and antiproliferative properties. (C) 2007 Elsevier Ltd. All rights reserved.
NOVEL DIBENZOTHIAZEPINES WITHOUT SUBSTITUTION ON THE SULFONAMIDE GROUP
ABSTRACT We have developed the synthesis of new thiazepine compounds bearing a non substitutedsulfonamide group, which is described through two different synthetic pathways, to design new anticancer structural families.
