  Dihydrothiophene-condensed chromones from a marine-derived fungus Penicillium oxalicum and their structure–bioactivity relationship

  摘要：

  Four dihydrothiophene-condensed chromones including two new compounds oxalicumones D-E (1-2) and known oxalicumones A-B (3-4), along with five other known chromones were isolated from a culture broth of the marine gorgonian-associated fungus Penicillium oxalicum SCSGAF 0023. The structures of 1-2 were elucidated by spectroscopic analysis. Eleven derivatives 3a-3i and 4a-4b were obtained from the acylation of 3 and 4, respectively. Compounds 1-4, 3a-3e, 3g-3h, and 4b showed significant cytotoxicity against several carcinoma cell lines with IC50 <= 10 mu M. And their structure-bioactivity relationship was discussed.

  Two new dihydrothiophene-condensed chromones and a new natural chromone, namely oxalicumones A-C (1-3), respectively, were isolated from a culture broth of a marine-derived fungus, Penicillium oxalicum. The structures of 1-3 and acetylated derivatives of 1 (4-7) were elucidated on the basis of spectroscopic methods and chemical reactions. The absolute configuration of 1 and 2 were established by using the modified Mosher ester method and circular dichroism data of an in situ formed [Rh-2(OCOCF3)(4)] and [Mo-2(OAc)(4)] complex. (R)-MTPA ester of 1 showed cytotoxicity against A375, SW-620, and HeLa carcinoma cell lines with IC50 values of 8.9, 7.8, and 18.4 mu M, respectively. Compound 1 displayed cytotoxicity against A375 and SW-620 cell lines with IC50 values of 11.7 and 22.6 mu M, respectively. The structure-biological activity relationship of 1 was discussed.
