Oreganic acid: a potent novel inhibitor of ras farnesyl-protein transferase from an endophytic fungus
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
The present invention is aimed at a process for obtaining oreganic acid and derivatives thereof, to the intermediate compounds of this synthesis and to the use of
