Terpenoids from Penicillium chrysogenum MT-40, an endophytic fungus isolated from Huperzia serrata

Abstract

Two novel 3,5-dimethylorsellinic acid derived meroterpenoids, peniciterpenolides A (1) and B (2) individually containing a 2-oxaspiro[4,5]deca-6,8-diene-1,4-dione and a 6-oxabicyclic[3,2,1]oct-3-en-7-one motif, one new spongian-type diterpene, peniciterpenolide C (3), and one new...

“…The structure of the 3,5-dimethylorsellinic acid (DMOA) derived meroterpenoid peniciterpenolide A 12 , a metabolite of Penicillium chrysogenum MT-40 obtained from Huperzia serrata , was established by X-ray analysis. 11 Peniciterpenolide A 12 has a novel spiro skeleton. Fifteen new DMOA-derived meroterpenoids, including littoreanoid A 13 , have been produced by mangrove-derived Penicillium sp.…”
