|Biological Activity or Inhibitors:||1. An isoflavone glycitin is isolated from the licorice, which has good inhibitory effect on α-glucosidase with IC50of 0.5646 mg·mL- 1, better than the position control acarbose.
2. Glycitin, daidzin, and genistin may modulate differentiation of MSC to cause a lineage shift toward the osteoblast and away from the adipocytes, and could inhibit adipocytic transdifferentiation of osteoblasts, they could also be helpful in preventing the development of osteonecrosis.
3. Glycitein has a protective effect on skin aging by inhibiting of MMP-1 and increasing of collagen through ERK/JNK/P38 down-regulation, which may be mediated by the inhibition of ERK, JNK, and p38 mitogen-activated protein kinases, suggests that glycitin is a potential agent for the treatment of skin ageing.

|Anti-obese and anti-diabetic effects of a mixture of daidzin and glycitin on C57BL/6J mice fed with a high-fat diet.[Pubmed: 25209298]|
|Results showed that mice in HFISO had a significantly lower body weight and adipose tissue compared to HF group. Blood glucose, serum HbA1c, and serum insulin also showed lower levels in HFISO group. In addition, higher hepatic GSH level and lower serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) level were found in HFISO group mice. This suggests that the regulation of oxidative stress by daidzin and Glycitin was closely related to the suppression of adipose tissue and the progression of diabetes.|

|Soy isoflavones and other isoflavonoids activate the human bitter taste receptors hTAS2R14 and hTAS2R39.[Pubmed: 21942422]|
|The aim of this study was to identify the bitter receptor(s) that recognize the bitter taste of the soy isoflavone genistein. Screening of all 25 human bitter receptors revealed genistein as agonist of hTAS2R14 and hTAS2R39. Genistein displayed threshold values of 4 and 8 μM on hTAS2R14 and hTAS2R39 and EC(50) values of 29 and 49 μM, respectively. In addition, the behavior of structurally similar isoflavonoids was investigated. Although the two receptors are not closely related, the results for hTAS2R14 and hTAS2R39 were similar toward most isoflavonoid aglycones. By trend, threshold values were slightly lower on hTAS2R14. Glucosylation of isoflavones seemed to inhibit activation of hTAS2R14, whereas four of five glucosylated isoflavones were agonists of hTAS2R39, namely, Glycitin, genistin, acetylgenistin, and malonylgenistin.|

|Characterization of a β-glucosidase from Sulfolobus solfataricus for isoflavone glycosides.[Pubmed: 21898127]|
|The specific activity of a recombinant β-glucosidase from Sulfolobus solfataricus for isoflavones was: daidzin > Glycitin > genistin > malonyl genistin > malonyl daidzin > malonyl Glycitin. The hydrolytic activity of this enzyme for daidzin was highest at pH 5.5 and 90°C with a half-life of 18 h, a K (m) of 0.5 mM, and a k (cat) of 2532 s(-1). The enzyme converted 1 mM daidzin to 1 mM daidzein after 1 h with a molar yield of 100% and a productivity of 1 mM h(-1). Among β-glucosidases, that from S. solfataricus β had the highest thermostability, k (cat), k (cat)/K (m), conversion yield, and productivity in the hydrolysis of daidzin.|

|Effects of genistein, daidzein and glycitein on the osteogenic and adipogenic differentiation of bone marrow stromal cells and on the adipogenic trans-differentiation of osteoblasts[Reference: WebLink]|
|It suggests that genistein, daidzein and glycitein regulate a dual differentiational process of MSCs into the osteogenic and adipogenic lineages, and trans-differentiational process of primary osteoblasts into the adipocyte lineages, causing a lineage shift toward osteoblast. Protective effects of them on bone may be mediated by a reversal of adipogenesis which may promote the proliferation, differentiation and mineralization of osteoblasts, and make adipocytes secrete less cytokines which may promote osteoclast formation and activation. In addition, the results also indicated that genistein, daidzein and glycitein may be helpful in preventing the development of steroid induced osteonecrosis.|

|The Protective Effect of Glycitin on UV-induced Skin Photoaging in Human Primary Dermal Fibroblast[Reference: WebLink]|
|Especially we focused on the expression of Matrix metalloproteinase-1 (MMP-1), which degrades procollagen type-I in dermis, by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, Western blot, and reverse transcription polymerase chain reaction in cell lysates or media. Our results showed that Glycitin increased the viability of human dermal fibroblast and alleviated MMP-1 expression caused by UV irradiation. In addition, synthesis of type-I collagen was increased and UV-induced phosphorylation of ERK/JNK/p38 was decreased in dose-dependent manners. Taken together, we demonstrated that treatment with glycitein have a protective effect on skin aging by inhibiting of MMP-1 and increasing of collagen through ERK/JNK/P38 down-regulation, which may be mediated by the inhibition of ERK, JNK, and p38 mitogen-activated protein kinases. We suggest that Glycitin is a potential agent for the treatment of skin ageing.|
