    Stephacidin B
    • Detailed Description

      CAS Number: 360765-75-9

      Molecular Formula: C52H54N6O8

      Molecular Weight: 212.3

      Tariff Code: 3822.00.5090

    • Applications

      Cancer Applications:

      Stephacidin B was reported as a potent antitumor agent by Bristol Myers Squibb (2002) against testosterone-independent PC3 and testosterone-sensitive LNCaP prostate cell lines with IC50 of 0.47 and 0.06 µM respectively.  Stephacidin is active against sensitive and resistant ovarian, colon and breast cancer cell lines.

      The stephacidin family of of natural anticancer agents are active against the human colon HCT 116 cell line.  The signature bicyclo [2.2.2] diazaoctane ring system common to these alkaloids has inspired many synthetic approaches.

    Stephacidin B, the dimer of avrainillamide, is green pigment isolated from Aspergillus ochraceus and other Aspergillus sp.  Stephacidin B is more potent and selective than its monomeric analog, stephacidin A. Stephacidin B is rapidly converted to avrainillamide in cell culture.  This natural alkaloid is used in cancer research.  

    Stephacidin B is soluble in methanol or DMSO.
