  • Patent number: 8563599
    Abstract: Two distinct methods are disclosed and claimed for synthesizing glyceollin I plus glyceollin II as a mixture and as their pure forms. Stereochemical isomers and various synthetic intermediates are also synthesized and claimed for their novel compositions of matter. All compounds and their mixtures are claimed for use in formulations that are useful to treat or prevent cancer, or that have utility as selective estrogen receptor modulators, such formulations including enhanced or medical foods, dietary supplements and ethical pharmaceutical agents.
