The first totalsyntheses of racemic glyceollin I and its enantiomers are described. A Wittig approach was utilized as an entry to the appropriately substituted isoflav-3-ene so that an osmium tetroxide mediated asymmetric dihydroxylation could be deployed for stereospecific introduction of the 6a-hydroxy group. While using triphenylphosphine hydrobromide, a novel method was found for gently removing

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.

New pharmaceutical compounds of general formula (I): F-(X)q where q is an integer from 1 to 5, preferably 1; -F is chosen among drugs described in the text, -X is chosen among 4 groups -M, -T, -V and -Y as described in the text.
The compounds of general formula (I) are nitrate prodrugs which can release nitric oxide in vivo in a controlled and selective way and without hypotensive side effects and for this reason they are useful for the preparation of medicines for prevention and treatment of inflammatory, ischemic, degenerative and proliferative diseases of musculoskeletal, tegumental, respiratory, gastrointestinal, genito-urinary and central nervous systems.

2-Hydroxyisoflavanone dehydratase substantially having the amino acid sequence represented by SEQ ID NO: 1 is isolated from licorice. Further, a polynucleotide encoding 2-hydroxyisoflavanone dehydratase of the SEQ ID NO: 2 is obtained. Furthermore, the amino acid sequence of 2-hydroxyisoflavanone dehydratase is identified from soybean and a polynucleotide encoding 2-hydroxyisoflavanone dehydratase is obtained.
2-羟基异黄酮酮脱水酶,其氨基酸序列主要由SEQ ID NO: 1表示,从甘草中分离出来。此外,获得了编码SEQ ID NO: 2的2-羟基异黄酮酮脱水酶的多核苷酸。此外,从大豆中鉴定出2-羟基异黄酮酮脱水酶的氨基酸序列,并获得了编码2-羟基异黄酮酮脱水酶的多核苷酸。
