  • Total synthesis of silychristin, an antihepatotoxic flavonolignan
    作者:Hitoshi Tanaka、Masaru Hiroo、Kazuhiko Ichino、Kazuo Ito
    DOI:10.1039/c39880000749
    日期:——
    The first total synthesis of silychristin is reported; the key intermediate [the dihydrobenzofuran (9)] was easily prepared in three steps from the readily available chalcone epoxide (6).

  • Compositions containing silymarin and sulfoalkyl ether cyclodextrin and methods of using the same
    申请人:UNIVERSITY OF KANSAS
    公开号:US10702568B2
    公开(公告)日:2020-07-07
    Cosmetic and dietary supplement compositions containing silymarin and sulfoalkyl ether cyclodextrin, particularly sulfobutyl ether cyclodextrin, are described. The compositions and methods are useful in reducing appearance of facial redness in rosacea-prone skin, rejuvenating skin, preventing skin aging, inhibiting oxidative stress in epidermal and dermal cells, increasing collagen production, reducing the likelihood of skin cancer, treating or reducing liver damage from a toxin, or treating a liver disease.

  • Total synthesis of silychristin, an antihepatotoxic flavonolignan.
    作者:Hitoshi TANAKA、Masaru HIROO、Kazuhiko ICHINO、Kazuo ITO
    DOI:10.1248/cpb.37.1441
    日期:——
    The total synthesis of silychristin, an antihepatotoxic flavonolignan, is described. The key intermediate, the transdihydrobenzofuran (15) was synthesized as follows. Treatment of the chalcone epoxide (9) with boron trifluoride etherate and subsequent reduction with sodium borohydride gave exclusively the erythro-1, 2-diaryl-1, 3-propanediol (10). Hydrogenolysis of 10 with hydrogen over a palladium catalyst followed by cyclization of the debenzylation product (13) with boron trifluoride etherate in acetic acid afforded 15 as a single product.
