Product Introduction

Bioactivity

名称5'-N-Ethylcarboxamidoadenosine
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.
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].
体外活性在体外培养的产Epo肝细胞癌(Hep3B)细胞系中,使用5'-N-Ethylcarboxamidoadenosine(≥10(-6)M)处理20小时于低氧条件下(1% O2),与低氧对照组相比,培养基中的Epo水平显著增加。在低氧环境中,以10(-7)M至5 x 10(-5)M浓度范围的5'-N-Ethylcarboxamidoadenosine处理肝细胞癌细胞1小时,其cAMP水平也显著高于低氧对照组。对肝细胞癌细胞膜制备进行的[3H]5'-N-Ethylcarboxamidoadenosine结合的Scatchard分析显示,低亲和力结合位点的解离常数(Kd)为0.44 μM,结合能力为863fM/mg蛋白。这表明,5'-N-Ethylcarboxamidoadenosine在低氧条件下促进Epo产生的增加,至少部分可以归因于刺激与腺苷酸环化酶激活相耦合的腺苷A2受体。
体内活性5'-N-Ethylcarboxamidoadenosine,一种腺苷类似物,对红细胞生成素(Epo)的生产有影响。5'-N-Ethylcarboxamidoadenosine(分别为0.05和0.1 mumol/kg i.v.)在缺氧后的多血红蛋白小鼠体内,通过四小时的低氧暴露,显著提高了血清Epo水平(分别为368.8 +/- 56.1和384.6 +/- 45.9 mU/ml),与低氧对照组(133.2 +/- 18.2 mU/ml)相比有显著差异。低氧状态下的肾脏Epo水平为46.4 +/- 13.4 mU/kg肾脏,明显高于常氧肾脏Ep水平(< 1.24 mU/kg肾脏)。茶碱(20 mg/kg i.p.),一种腺苷受体拮抗剂,显著抑制了5'-N-Ethylcarboxamidoadenosine对血清Epo水平的刺激效果[1]。
