[摘要]：Introduction: Norcantharidin (7-oxabicyclo [2.2.1] heptane-2,3-dicarboxylic anhydride) is the demethylated form of cantharidin. Norcantharidin not only has strong anticancer activity, but also eliminates most side-effects in the urinary system, does not cause myelosuppression and increases the number of white blood cells. With structural modification, norcantharidin analogues show potential anticancer activities.Areas covered: A comprehensive patent review of norcantharidin analogues from 2006 to 2010 is presented. Protein phosphatase 1, 2A, 2B and 5 inhibitors are described. The review summarizes the new compounds and lays the foundation for seeking more effective anticancer compounds.Expert opinion: Although norcantharidin has improved activity and toxicity, the effects routinely do not satisfy the current clinical need. Exploring better analogues is vital for changing the current situation, but norcantharidin is a good lead compound. |
