Synthesis and evaluation of benzophenone-based photoaffinity labeling analogs of prenyl pyrophosphates containing stable amide linkages
摘要:
The syntheses of two photoactive prenyl pyrophosphate analogs (1a and 1b) that incorporate stable amide-linked benzophenones are described. Compound 1a contains a single isoprene (C-5) unit between the pyrophosphate and benzophenone functionalities while 1b contains a geranyl (C-10) moiety. Compounds 1a and 1b are competitive inhibitors of yeast farnesyl protein transferase with respect to farnesyl pyrophosphate and have K-I values of 6000 nM and 700 nM. Upon irradiation, [P-32]-1b preferentially labels the beta-subunits of yeast farnesyl protein transferase and human geranylgeranyl protein transferase. (C) 1997 Elsevier Science Ltd.
