Isoflavonoid induction and nitrogen assimilation in AM colonized red clover
… soluble protein concentration; (3) contents of isoflavonoids (e.g. genistein, daidzein, biochanin A, and formononetin); and (4) contents of these four isoflavonoids over time and with a hormonal factor, jasmonic acid (JA). To accomplish these objectives, four greenhouse experiments were …

Inactivation of Helicoverpa armigera nucleopolyhedrovirus on chickpea, Cicer arietinum L.
… effect was relatively small. Bioassays with the isoflavonoids (biochanin A and formononetin), identified to be present or induced at higher levels after spraying with HearNPV, showed that although both compounds significantly reduced NPV efficacy, the effect was modest compared to that recorded …

Indirect Effects of Elevated Carbon Dioxide on Members of Three Herbivorous Feeding Guilds on Soybean, Glycine Max
… amounts of flavonols and decreased amounts of isoflavonoids in leaves grown under elevated CO2 may contribute to increased herbivore longevity and fecundity. A. glycines population growth is greater on soybeans grown under elevated levels of CO2, which may be the result of increased leaf …

Dietary Soy Protein Isoflavonoid Effects on the Reproductive Tract of the Nonhuman Primate and Neoplastic Human Prostate Gland
… polyphenolic, estrogen-like compounds termed isoflavonoids. Following the consumption of a soy-containing meal, isoflavonoids are absorbed in the gut, and can be detected in the serum in nanomolar concentrations. These polyphenolic compounds are structurally similar to the endogenous sex …

Evaluation of a modified food frequency questionnaire to measure lignans in Australian men and women
… postulated to protect against chronic diseases. Isoflavonoids and lignans are two main classes of phytoestrogen that have been investigated for their estrogenic efficacy and occurrence in the human diet. Isoflavonoids are found in soy and related products, whereas lignans are found in a wider …

Soybean (Glycine max (L.) Merr.); nodulation mutant characterization: Role of isoflavonoid, nitrate, and abscisic acid in nodulation control
Isoflavonoids (daidzein, genistein, and coumestrol) are known to be inducers of nod genes in Bradyrhizobium japonicum. This study evaluated the effect of inoculation and nitrogen on isoflavonoid concentration in soybean (Glycine max (L.) Merr.) root extracts from selected hypernodulating mutants …

Impact of host plants on the efficacy of nucleopolyhedrovirus as a biopesticide against insect pest Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)
… sissotrin. This is the first study to show that isoflavonoids reduce the efficacy of baculovirus against Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). Field trials were also conducted with different low cost additives mixed with HearNPV on chickpea crop and these increased the efficacy …

Design and synthesis of novel biologically active flavones and isoflavones
… or analogues that structurally resemble isoflavonoids. In addition, the incorporation of fused-ring systems into the isoflavonoid scaffold to synthesize analogues of a bioactive natural product was also explored. The synthesized analogues were tested against cancer cells with results …

BIOACTIVATION OF NATURAL DIETARY PRODRUGS BY SPECIFIC CYTOCHROME P450 ENZYMES
… acid (/-RA), vitamin D3, and the isoflavonoids genistein and daidzein. These compounds were found to be poor substrates for CYPl enzymes. In contrast, synthetic chaicone analogues of a natural chaicone butein, DMU2123 and DMU2127, were found to be substrates of the CYPl Al enzyme. …
