产品描述 Doxycycline hyclate (WC2031) belongs to the tetracycline class of antibiotics and is a broad-spectrum metalloproteinase (MMP) inhibitor with oral activity. Doxycycline hyclate has antibacterial activity and antitumor activity.
体外活性 方法:22 种肿瘤细胞用 Doxycycline hyclate 处理 48 h,使用 MTT 方法检测细胞活力。
结果:肺癌细胞对 Doxycycline 比其他大多数细胞系更敏感。NCI-H446 和 A549 细胞对 Doxycycline 敏感,IC50分别为 1.70 μM 和 1.06 μM。[1]
方法:人胰腺癌细胞 PANC-1 用 Doxycycline hyclate (10-40 μg/mL) 处理 8-24 h,使用 Flow Cytometry 方法检测细胞周期情况。
结果:Doxycycline 使细胞停滞在细胞周期的 G1-S 期。[2]
体内活性 方法:为检测体内抗肿瘤活性,将 Doxycycline hyclate (50 mg/kg) 腹腔注射给携带人乳腺癌肿瘤 4T1 的 BALB/c 小鼠,每天一次,持续十五天。
结果:Doxycycline 延迟肿瘤生长并降低肿瘤相关巨噬细胞和血管的数量。[3]
方法:为检测体内抗菌活性,将 Doxycycline hyclate (40 mg/kg) 腹腔注射给暴露于 B. pseudomallei 1026b 的 BALB/c 小鼠,每天两次,持续两周。
结果:用 Doxycycline 治疗的小鼠 100% 存活,并且从大多数存活小鼠的肺或脾脏中没有扩增出 B. pseudomallei 的 DNA。[4]
激酶实验 Gelatin (0.1% (w/v) is added to standard LaemmLi acrylamide polymerization mixture. Tissue extract is mixed 1:2 with sample buffer [250 mM Tris-Cl pH 6.8, 10% (w/v) SDS, 20% (v/v) glycerol, 0.005% (w/v) bromphenol blue]. Serum is diluted 1:10 with electrophoresis buffer (2.5 mM Tris, 20 mM glycine, 0.005% SDS) and mixed 1:2 with sample buffer. Twenty μLs are loaded after 10-min incubation at room temperature without boiling. After electrophoresis at 90 V, the gels are soaked in 2.5% (w/v) Triton X-100, incubated 2 to 3 days at 37°C in gelatin digestion buffer [50 mM Tris-Cl, pH 8.0, 8 mM CaCl2, 10 mM ZnSO2, 0.02% (w/v) NaN3], stained in 0.05% Coomassie blue R-250 in acetic acid/methanol/water (1:4.5:4.5 by volume), destained in 10% acetic acid and 5% methanol, and scanned for lysis band intensity. The lysis band intensity is proportional to gelatinase activity and is quantified densitometrically by using One-Dimensional Scan software. The result, a number between 0.07 and 3.75, is normalized to the protein content by dividing the densitometry result with the relative optical density from the BCA protein assay kit result. The result is used for the analysis as the arbitrary unit. For the total MMP activity results of lysis bands of pro-MMP-9, active MMP-9, pro-MMP-2, and active MMP-2 are added. A protein size marker is used to determine the correct size.
细胞实验 Doxycycline is diluted in culture medium at a concentration of 10 μg/mL. All in vitro treatments are performed in SMC cultures at 90% confluence, when ECM synthesis in SMC starts to be evident. Doxycycline (20 nM) is diluted in culture medium at a concentration of 10 μg/mL (20 nM), at which no toxicity or variation in primary cultured SMC proliferation has been reported, as well as in other cell lines and the incubation time is 48 h. SMC-C and SMC-Ch are seeded at equal cell density in 6-well plates and, when confluence reaches 90%, 1 mL culture medium is added to each well containing 3.7×104?Bq L-[5-3H]-proline (9.62×1011 Bq/mmol). After 48?h incubation, cells are lysed with 0.5 mL 0.5 mol/L NaOH for 1 h. The resulting solution is neutralized with an equal amount of 0.5 mol/L HCl, and 50 μL are used to measure total proteins with the Bradford method. One volume of 10% TCA is added to the remaining 250 μL and centrifuged at 13,000 g for 15?min at 4°C. The resulting precipitate is dissolved in 100 μL 0.2 mol/L NaOH, and then neutralized with 1 mol/L HCl. The solution is incubated with collagenase buffer (Tris-HCl, pH 7.6 20 mM, and CaCl2 250 mM final concentration) and 10 units of collagenase at 37°C overnight. Then, 150 μL 10% TCA are added and centrifuged at 13000 g for 15?min at 4°C. The resulting supernatant is added to 4 mL of scintillation fluid and the radioactivity is measured in a liquid scintillation counter LS 600 TA.

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。

体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
