Semisynthesis of miltirone, 1,2-dehydromiltirone, saligerone from carnosic acid and cytotoxities of their derivatives
摘要:
Miltirone, 1,2-dehydromiltirone, saligerone have been synthesized form carnosic acid. Among them, one step transformation of carnosic acid into miltirone was realized when decarboxylation/aromatization was promoted by Lewis acid. Moreover, 4 derivatives exhibited potent cytotoxic activities against three human cancer lines in vitro. (C) 2018 Published by Elsevier Ltd.

A composition comprising tanshinone compounds selected from the group consisting of miltirone, 1,2-didehydromiltirone, tanshinone IIA, tanshinone I and dihydrotanshinone I isolated from
Salviae miltiorrhizae
Bunge showing potent inhibiting effect on the aggregation and toxicity of beta-amyloid and recovering activity of memory learning disorder confirmed by Y maze study and Passive Avoidance study. Therefore it can be used as the therapeutics or health food for treating and preventing cognitive function disorder with safe.
Use of Conjugated Dienones in Cyclialkylations: Total Syntheses of Arucadiol, 1,2-Didehydromiltirone, (±)-Hinokione, (±)-Nimbidiol, Sageone, and Miltirone
Functionalized hydrophenanthrenes can be prepared using a cyclialkylation-based strategy. These annulations are highly dependent on the directing effects of the arene substitutents and on conformational considerations. The utility of this methodology was featured in the syntheses of six diterpenoids.
