产品描述	5'-N-Ethylcarboxamidoadenosine (NECA) is an agonist of Adenosine receptor, increases cerebral extravasation of fluorescein and low molecular weight dextran independent of blood-brain barrier modulation.
体外活性	In vitro cultures of an Epo producing hepatocellular carcinoma (Hep3B) cell line with NECA (> or = 10(-6) M) for 20 hours under hypoxic conditions (1% O2) produced significant increases in medium levels of Epo when compared with hypoxia controls. Hepatocellular carcinoma cells treated with NECA at a concentration range of 10(-7) M to 5 x 10(-5) M for one hour in a hypoxic atmosphere also had significantly higher cAMP levels than that of hypoxia controls. Scatchard analyses of [3H]NECA binding to membrane preparations of hepatocellular carcinoma cells showed low affinity binding sites with a dissociation-constant (Kd) of 0.44 microM and a binding capacity of 863 fmol/mg protein. Suggest that the increase in Epo production in response to NECA under hypoxic conditions can be attributed, at least in part, to stimulation of adenosine A2 receptors which is coupled to adenylyl cyclase activation[1].
体内活性	NECA, an adenosine analogue, on erythropoietin (Epo) production. NECA (0.05 and 0.1 mumol/kg i.v.) produced significant increases in serum Epo levels (368.8 +/- 56.1 and 384.6 +/- 45.9 mU/ml, respectively) in exhypoxic polycythemic mice after a four hour exposure to hypoxia when compared with hypoxia controls (133.2 +/- 18.2 mU/ml). The hypoxic kidney Epo levels were 46.4 +/- 13.4 mU/kg kidney which were significantly higher than normoxic kidney Ep levels (< 1.24 mU/kg kidney). Theophylline (20 mg/kg i.p.), an adenosine receptor antagonist, significantly inhibited the stimulatory effects of NECA on serum Epo levels[1].
细胞实验	A human hepatocellular carcinoma cell line (Hep3B) was employed to determine the in vitro effects of NECA on Epo production and cAMP accumulation. Hep3B cells were carried in a monolayer cell culture and maintained in 75 cm^2 Corning culture flasks containing Eagle's minimal essential medium (MEM) supplemented with 10% fetal bovine serum (PBS), 0.1 m nonessential amino acids, 1 m sodium pyruvate, 100 U/ml penicillin G, and 100 μg/ml streptomycin in a humidified atmosphere of 5% C02/95% air at 37℃. The culture medium was replaced every two days. Cells were detached with trypsin and aliquots of 2.5 x 10^5 viable cells (determined by trypan blue dye exclusion) were transferred to 24 multi-well plates. Each experiment was carried out with low density cells before they reached confluency. The cells were incubated with NECA in concentrations of 1O^9 M to 5 x l0^-5 M in the presence of 1 U/ml adenosine deaminase (ADA) under hypoxic conditions (1% 02, 5% C02, and 94% N2) for 20 hours following 24 hour preincubation in a normoxic atmosphere. At the end of the incubation period, the supernatant was harvested and frozen at -70℃ prior to Epo RIA. The multiple-range test of Duncan was used for the comparison of the several in vitro treatment groups compared with controls[1].

体内实验配液计算器

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。
