| pubmed-article:2681537 | pubmed:abstractText | Intricatin [1] and intricatinol [2] are new homoisoflavonoids isolated from a desert plant Hoffmanosseggia intricata, which was collected in Baja California, Mexico. The structures of the compounds were elucidated using a variety of spectroscopic techniques. The structure of 1 was shown to be 7,4'-dimethoxy-8-hydroxyhomoisoflavone, and 2 was shown to be 4'-methoxy-7,8-dihydroxyhomoisoflavone. Both compounds 1 and 2 displayed activity in the inhibition of the mutagenicity of 2AN toward Salmonella typhimurium (T98). Compound 2 was much more active than 1 in the case of the inhibition of the mutagenicity of AAF toward S. typhimurium (T98) and the inhibition of EMS towards S. typhimurium (T100). Compounds 1 and 2 are the first examples of antimutagenic activity in homoisoflavones. | lld:pubmed |
