In this paper we describe the synthesis of a family of CAAL peptidomimetics as GGTase-I inhibitors. These inhibitors lack the central dipeptide AA in the key CAAL carboxy terminal sequence of geranylgeranylated proteins and are more selective for GGTase-I over FTase. In whole cells, these compounds are very potent inhibitors of the processing of the geranylgeranylated protein Rap1A without affecting the farnesylated protein H-Ras. One derivative, GGTI-298, inhibited cell division by blocking cells in the G1 phase of the cell cycle.
