  Structure and antitumor activity relation of 2-arylidene-4-cyclopentene-1,3-diones and 2-arylideneindan-1,3-diones

  摘要：

  A series of 2-arylidene-4-cyclopentene-1,3-diones and 2-arylideneindan-1,3-diones, as well as mono- and bis(arylidene substituted)cycloalkanones, was synthesized and examined for antitumor activity against ascites sarcoma-180. All the 2-arylidene-4-cyclopentene-1,3-diones and one arylideneindan-1,3-dione (where the arylidene group was either a hydroxybenzylidene or substituted hydroxybenzylidene) exhibited a high degree of activity. Among both types of 1,3-diones and 3-methoxy-4-hydroxybenzylidene derivatives were found to possess the greatest potency, while all the mono- and bis(arylidene)cycloalkanones were found to be inactive.

  A series of simple desmethoxy analogues of coruscanone A was prepared via a novel version of Ti(iPrO)(4)-mediated Knoevenagel condensation of cyclopentenedione with substituted benzaldehydes and cinnamic aldehydes, and the compounds were evaluated for antifungal activity and cytotoxicity. The most potent 2-benzylidenecyclopent-4-ene-1,3-dione possessed antifungal effect comparable to coruscanone A and a somewhat broader spectrum of activity against Candida species. The compound was also superior to fluconazole against several non-albicans Candida sp. Evaluation of the ability of the compound to influence cell proliferation using two different assays showed that 2-benzylidenecyclopent-4-ene-1,3-dione has lower cytotoxicity compared to the natural product.
