Abstract

We herein describe the synthesis of novel dipyrrolo- and furopyrrolopyrazinones related to highly cytotoxic tripentones and to their oximes. The synthetic pathway involved in particular a Curtius rearrangement and a subsequent cyclisation into the title pyrazinones. The biological evaluation towards various cyclin-dependent kinases (CDKs1-5, GSK-3) highlighted a weak inhibitory activity for the oximes whose SAR was studied by a molecular modeling study.
