此方案可獲得 ≥ 2.5 mg/mL (13.29 mM,飽和度未知) 的澄清溶液,此方案不適用于實(shí)驗(yàn)周期在半個(gè)月以上的實(shí)驗(yàn)。
以 1 mL 工作液為例,取 100 μL 25.0 mg/mL 的澄清 DMSO 儲(chǔ)備液加到 900 μL玉米油中,混合均勻。
<1mg/ml表示微溶或不溶。
普西唐提供的所有化合物濃度為內(nèi)部測(cè)試所得,實(shí)際溶液度可能與公布值有所偏差,屬于正常的批間細(xì)微差異現(xiàn)象。
請(qǐng)根據(jù)產(chǎn)品在不同溶劑中的溶解度選擇合適的溶劑配制儲(chǔ)備液;?旦配成溶液,請(qǐng)分裝保存,避免反復(fù)凍融造成的產(chǎn)品失效。
靶點(diǎn):
COX-2;Human Endogenous Metabolite
體外研究:
Gallic acid is an antioxidant which can inhibit both?COX-2. After 18?h treatment with Gallic acid, the number of viable neutrophils is dramatically decreased from 40.3% to 27.7%, highly comparable with 26.4% for untreated neutrophils. Gallic acid fails to attenuate isoproterenol-induced myocytolysis.
體內(nèi)研究:
The food intake (2.6±0.08 g/day, p=0.69) and the body weight (2.5±0.69 g, p=0.76) of the Gallic acid group do not differ significantly from those of the control group (food intake; 2.41±0.14 g/day and the body weight; 2.83±0.84 g/day). The blood glucose tolerance in the Gallic acid group is significantly improved after 2 weeks of treatment. The blood glucose tolerance of the Gallic acid group after a treatment period of 2 weeks is also significantly better than that of the control group at 90 and 120 min ( p<0.05). The serum triglyceride concentration in the Gallic acid group (0.67±0.03 mM, p<0.05) is significantly reduced relative to that of the control group (1.08±0.20 mM). The total?cholesterol?concentration is similar in the control (3.19±0.27 mM) and Gallic acid (3.01±0.18 mM) groups.
