Inhibitors of Protein:Farnesyl Transferase and Protein:Geranylgeranyl Transferase I: Synthesis of Homologous Diphosphonate Analogs of Isoprenylated Pyrophosphate
摘要:
Novel diphosphonate homologs 7a-7c, and their cyclic counterparts 8a-8c, of the previously synthesized farnesyl pyrophosphate analogs 1 and 2 were prepared and tested for their inhibition potency and specificity of the enzymes PFT and PGGT-I. Compound 2 was shown to be the most potent inhibitor of PFT (IC50 = 0.58 +/- 0.45 mu M) in this series. The novel compound 7a, the one carbon homolog of 2, proved to be the most potent inhibitor of PGGT-I (IC50 = 0.98 +/- 0.01 mu M). The cyclic analogs 8a-8c are generally less biologically active. The compounds 2 and 7a are nonspecific toward inhibition of PFT and PGGT-I: and may inhibit both farnesylation and geranylgeranylation processing of oncogenic proteins. (C) 1998 Academic Press.
