In vitro study | Verbascoside acts as an ATP-competitive inhibitor of PKC, with an IC 50 of 25 µM. Verbascoside shows K i s of 22 and 28 µM with respect to ATP and histone, respectively. Verbascoside has potent antitumor activity against L-1210 cells, with an IC 50 of 13 µM. Verbascoside (5, 10 µM) suppresses 2,4-dinitrochlorobenzene (DNCB)-induced T cell costimulatory factors CD86 and CD54, proinflammatory cytokines, and NFκB pathway activation in THP-1 cells. |
In vivo study | Verbascoside (1%) reduces the overall scratching behavior incidence as well as the severity of the skin lesions in 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) mice model. Verbascoside also blocks DNCB-induced expression of proinflammatory cytokine TNF-α, IL-6, and IL-4 mRNA in skin lesions. Verbascoside (50, 100 mg/kg, i.p.) does not modify chronic constriction injury (CCI)-induced cold allodynia. Verbascoside (200 mg/kg, i.p.) decreases hyper-sensitivity to cold stimulus, acetone, on day 3 in rats. Verbascoside also significantly reduces behavioral changes associated with neuropathy. Moreover, Verbascoside decreases Bax and increases Bcl-2 on day 3. |

overview | ergosterol is an oxygen glycoside in glycosides, also known as mullein and mullein. It is relatively stable under acidic conditions. The stability is poor under neutral and alkaline conditions, but the addition of appropriate amount of ascorbic acid can obviously inhibit its degradation. Mainly exist in some medicinal plants, such as Cistanche plants, Forsythia plants, Rehmannia plants and Ledang plants. Ergosterin has strong biological activity and various effects. It has the effects of anti-aging, improving immune function, enhancing memory, relieving pain, lowering blood lipids and laxative. |
preparation | extraction method of ergosterol from osmanthus fragrans, comprising the following steps: S1. Grind sweet osmanthus into powder; S2. Extraction with cable extractor; S3. The crude extract of Osmanthus fragrans obtained in step S2 is extracted and concentrated, preferably, the crude extract of Osmanthus fragrans is extracted and concentrated with petroleum ether, ethyl acetate, and water-saturated n-butanol; S5. Rotating at 40°C and then lyophilizing to obtain ergosterol. HPLC determination of concentrated sweet-scented osmanthus crude extract: preparation of sweet-scented osmanthus crude extract solution: accurately weigh 2mg of sweet-scented osmanthus crude extract, place it in a 25mL volumetric flask, add appropriate amount of methanol to dissolve and fix the volume, filter through a 0.45 μm filter membrane, and sweet-scented osmanthus crude extract solution solution. |
biological activity | Verbascoside are glycosides obtained from Lantana camara, which are ATP competitive PKC inhibitors with an IC50 value of 25 µM and have anti-tumor, anti-inflammatory, anti-neuropathic pain and other effects. |
target | PKC 25 μM (IC 50 ) |
