    摘要: Method for preparing a 3-deoxy-5-hydroxyanthocyanidin salt having a 4' and/or 7 OH substituent from a corresponding acylated flavanone, by (1) reducing the acylated flavanone in a solvent medium by reaction with an alkali borohydride to form a corresponding flavan not having an OH substituent at the 4 position, and (2) oxidizing the flavan or an acylated or hydrolyzed derivative of the flavan in an organic solvent medium by reaction with a halogenated benzoquinone in the presence of a strong acid and water. Suitable acylated flavanones include acetylated natural flavanones, especially acetylated naringenin and hesperetin.

    摘要: A cannabis-based flavonoid pharmaceutical composition including any one or more selected from among the group of Cannflavin A, Cannflavin B, Cannflavin C, Chrysoeriol, Cosmosiin, Flavocannabiside and their derivatives selected from among the group of Geraldol, Rhamnetin, Isorhamnetin, Rhamnazin, or their synthases, for the prevention and treatment of certain cancers that can be treated by therapeutically targeting oncogenic factors including kinases, sirtuins, bromodomains, matrix metalloproteinases and histone acetylases. Some of the cancers that can be treated by use of cannabis flavonoids based on the inhibition of these therapeutic targets include but are not limited to brain, breast, colon, renal liver, lung, pancreatic, pigmented villonodular synovitis, prostate, leukemia, melanomam, tenosynovial giant cell tumor, as well as any other cancers that overexpress the oncogenic factors inhibited, by the cannabis flavonoids or their derivatives herein identified.
