| Uses | Apigenin 7-Glucoside is a by-product during the synthesis of Isorhoifolin (I819700), a naturally occurring flavonoid that was shown to exhibit potential antidiabetic, antihyperlipidemic and antioxidant effects. |
| Application | Apigenin 7-glucoside is a flavonoid with anti-inflammatory and anxiolytic activities. It inhibits LPS-induced nitric oxide production in RAW 264.7 cells when used at concentrations ranging from 0.16 to 10 μM. In vivo, apigenin 7-glucoside (10 mg/kg) reduces pulmonary edema and lung inflammation in a mouse model of LPS-induced acute lung injury. It also increases the number of entries and the time spent in the open arms of the elevated plus maze in rats, indicating anxiolytic activity. |
| Definition | ChEBI: A glycosyloxyflavone that is apigenin substituted by a beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. |
| Biological Functions | Apigenin 7-glucoside inhibited HL-60 cell growth, dose- and time-dependently, but did not cause apoptosis. The distribution of cells at different stages in the cell cycle indicated an accumulation of treated cells in the G2/M phase. Moreover, apigenin 7-glucoside induced granulocytic differentiation of HL-60 cells[1]. |
| Synthesis | 119249-30-8 578-74-5 Compound 1 (CAS: 119249-30-8, 150 mg, 0.25 mmol) was dissolved in a mixture of methanol (20 mL) and 30% ammonia (5 mL) under stirring conditions. The reaction mixture was stirred continuously for 12 hours at room temperature. Upon completion of the reaction, the solvent was removed by distillation under reduced pressure. The resulting residue was purified by silica gel column chromatography using ethyl acetate/methanol (3:1, v/v) as eluent to afford the target product 5-hydroxy-2-(4-hydroxyphenyl)-7-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-4H-benzopyran-4-one , a yellow solid (78 mg, 72% yield). The melting point of the product was 234-236°C (literature value: 238-239°C). The infrared spectrum (KBr pressed sheet, cm^-1 ) showed characteristic absorption peaks: 3440, 2918, 1615, 1563, 1452, 1346, 1273, 1245, 1146, 1103, 1072, 1024, 895. the NMR hydrogen spectrum (400 MHz, DMSO-d6) δ: 12.97 (s, 1H, OH-5), 10.48 (s, 1H, OH-5), 10.47 (s, 1H). 10.48 (s, 1H, OH-4'), 7.96 (d, J = 8.8 Hz, 2H, H-2', H-6'), 6.94 (d, J = 8.8 Hz, 2H, H-3', H-5'), 6.87 (s, 1H, H-3), 6.83 (d, J = 1.6 Hz, 1H, H-8), 6.45 (d, J = 1.6 Hz, 1H, H-6), 6.45 (d, J = 1.6 Hz, 1H, H-8), 6.45 (d, J = 1.6 Hz, 1.6 Hz, 1.6 Hz), 6.85 (d, J = 1.6 Hz, 1.6 Hz, 1.6 Hz, 1.6 Hz, 1.6 Hz). 1H, H-6), 5.42 (d, J = 8.0 Hz, 1H, H-1), 5.15 (s, 1H, OH-2), 5.08 (s, 1H, OH-3), 5.06 (s, 1H, OH-4), 4.63 (s, 1H, OH-6), 3.72-3.70 (m, 1H, H-2), 3.49-3.18 (m, 5H H-3,4,5,6).
