Selective inhibition of type-I geranylgeranyltransferase in vitro and in whole cells by CAAL peptidomimetics
摘要:
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 G(1) phase of the cell cycle. (C) 1998 Elsevier Science Ltd. All rights reserved.
