摘要:
Inhibitors of farnesyl-protein transferase (FPTase) have the potential of being anticancer agents for tumors in which ras is found mutated and contributes to cell transformation. From the screening of the extracts tricarboxylated alkylsulfate, oreganic acid (1), as a potent (IC50 = 14 nM) and specific inhibitor of FPTase. Its desulfated analog (4) was less active (IC50 = 3.3 mu M). The trimethylester (2) and its desulfated analog (3) were inactive. Copyright (C) 1996 Elsevier Science Ltd
