Biological Information

  • Product Name
    Isoescin IB
  • Note
    Research use only, not for human use.
  • Brief Description
    Isoescin IB, isolated from horse chestnut tree seeds, is an isomer of Escin IB.
  • Description
    Isoescin IB, isolated from horse chestnut tree seeds, is an isomer of Escin IB. Isoescin IB and Escin IB are the chief active ingredients in escin.
  • In Vitro
    β-Escin (mainly consisting of escin Ia and escin Ib) is the major active ingredient in horse chestnut seeds extracts. β-escin can inhibit proliferation and/or induce apoptosis in various types of cancer cells including A549 cell, HT-29 cell, HCC cell, OVCAR3 cell and H-Ras 5RP7 cell. β-escin may be useful as a chemopreventive agent, especially for tumors associated with an inflammatory response. As the minor component of escin, α-escin (mainly consisting of isoescin Ia and isoescin Ib) exhibits lower bioactivity.
