Two new diterpenoids, konishone (1) and 3b-hydroxy-5,6-dehydrosugiol (2), along with three known diterpenoids--hinokiol (3), sugiol (4), and 12-hydroxy-6,7-secoabieta-8,11,13-triene-6,7-dial (5)--were isolated from the wood of Cunninghamia konishii. Compound 1 is a novel skeleton of the 7,20-dinorabietane-type diterpene. In addition, when RAW264.7(More)
