D-(-)-Salicin
(Synonyms: 水杨苷; D-(?)-Salicin; Salicoside) 目录号 : GN10430A non-selective COX inhibitor
Cas No.:138-52-3
Sample solution is provided at 25 µL, 10mM.
Salicin is a natural COX inhibitor.
Significant down regulation of PGE2, the enzymatic product of COX2, to 76% in lysate and 70% in supernatant is observed with Salicin 10 μM treatment in COLO cells when compare to the COLO control. This is accompanied with a minimal COX1 inhibition to 91% of the CCD control on the genetic level. Treatment with Salicin 1 μM decreases colon cancer cell proliferation rates from 144% to 113% at 24 hours and 187% to 130% at 48 hours, with 10 μM decreasing proliferation rates to108% at 24 hours and 119% at 48 hours[1]. The concentrations of TNF-α, IL-1β and IL-6 of LPS-induced cells pretreated with 0.07, 0.14 and 0.28 μM Salicin are significant reduced compare with LPS group[2].
Salicin (D(-)-Salicin) (35, 70, 140 μM) markedly inhibits the LPS-induced pathological changes. MPO activity in LPS-induced lung tissue is significantly increased compare with control group. However, Salicin (35, 70, 140 μM) markedly inhibits this change. Pretreatment with Salicin inhibits LPS-induced activation of JNK, ERK, p38/MAPK and p65 in a dose-dependent manner[2].

Cell experiment: |
RAW264.7 mouse macrophage cell line is used in this study. RAW264.7 cells are mechanically scraped and plated at a density of 4×105 cells/mL onto 96-well plates in a 37°C, 5% CO2 incubator for 1 h. Then the cells are treated with 50 μL Salicin (D(-)-Salicin) of different concentrations (0 to 0.28 μM) for 1 h, followed by stimulation with 50 μL Lipopolysaccharide (LPS) (4 μg/mL). After 18 h, 10 μL CCK-8 is added to each well and continued to incubate for 4 h. Then, the optical density is measured at 450 nm on a microplate reader[2]. |
Animal experiment: |
Mice are randomly divided into five groups, each containing three mice: Control, Lipopolysaccharide (LPS) only, LPS+Salicin (D(-)-Salicin) group is injected intraperitoneally with Salicin 35 μM, LPS+Salicin group is injected intraperitoneally with Salicin 70 μM, LPS+Salicin group is injected intraperitoneally with Salicin 140 μM. After 1 h, 10 μg LPS dissolved in 50 μL PBS is instilled intranasally to induce lung injury. Control mice are given 50 μL PBS without LPS. After 12 h LPS treatment, bronchoalveolar lavage fluid (BALF) is collected 3 times through a tracheal cannula with autoclaved PBS. Then, the tissue sample is centrifuged at 3000 rpm, for 10 min at 4°C[2]. |
