introduction: the role of adenosine a1 receptors of the entorhinal cortex on amygdaloid kindled seizures was investigated. material and methods: animals were kindled by daily electrical stimulation of amygdala. in the full kindled animals, n6-cyclohexyladenosine (cha; 0.1, 1 and 10 mm), an adenosine a1 receptor agonist, and 8-cyclopenthyle 1,3-dimethylexanthine (cpt), an adenosine a1 receptor a...

the effects of adenosine,5-n-ethylcarbox-amidoadenosine (neca), 2-chloroadenosine (2-ca), n6-phenyiisopropyladenos'tne (l-pia and d-pia) and n6 -cyclohexyladenos'tne (cha) were examined on the mouse isolated vas deferens. all the compounds in a concentration-dependent manner inhibited electrically induced contrac¬tions. ic of adenosine and its analogues were 13.68 ± 5.97 for ado, 0.736 ± 0.087 ...

The effects of intraperitoneal injection of N6-cyclohexyladenosine (CHA, a selective adenosine A1 receptor agonist) and 8-cyclopenthyle-I-3-dimethylexanthine (CPT, a selective adenosine A1 receptor antagonist) on entorhinal cortex-kindled seizures were investigated. Fully entorhinal cortex-kindled rats received normal saline (control), CHA (0.06, 0.12 and 0.25 mg/kg) or CPT (0.06 and 0.12 mg/kg...

In this study the role of adenosine A1 receptors of the CA1 region of hippocampus on piriform cortex–kindled seizures was investigated in rats. Obtained results showed that in kindled animals, bilateral microinjection of N6–cyclohexyladenosine (CHA), an adenosine A1 receptor agonist, at doses of 10 and 100 mM into the hippocampal CA1 region decreased the afterdischarge duration (ADD), stage 5 s...

Background: In this study, the effects of three structural analogues of adenosine upon proliferation of human tumor cells were investigated. Previous research showed a cytotoxic effect of adenosine via A3 receptor and A1 receptor and sometimes this effect was receptor independent. The researches showed a differential cytotoxic effect of adenosine and its A3 agonists on cancerous cells, while ot...
