White Solid

The Uses of NECA

A potent adenosine receptor agonist. Inhibits platelet aggregation and is centrally active in vivo

The Uses of NECA

Potent adenosine receptor agonist with some affinity at A1 and A2 receptors

The Uses of NECA

5′-(N-Ethylcarboxamido)adenosine has been used:

• for the purification of human adenosine A_2Areceptor (A_2AR) in decylmaltoside (DM)
• to determine nonspecific binding of adenosine receptors
• to investigate adenosine 2B receptor (RA2B) mechanism of action by competition assay

What are the applications of Application

5′-N-Ethylcarboxamidoadenosine is a potent Adenosine A Receptor agonist

Definition

ChEBI: A derivative of adenosine in which the 5'-hydroxymethyl group is replaced by an N-ethylcarboxamido group.

General Description

A cell-permeable adenosine analog that acts a potent non-selective agonist of adenosine receptors (K_i = 14 nM, 20 nM, 2.4 μM and 6.2 nM for A₁, A_2A, A_2B, A₃, respectively). Increases intracellular cAMP production (EC₅₀ = 3.1 μM in A_2B expressing CHO cells). Shown to increase glucagon release in a dose-dependent manner and inhibit insulin release at low concentrations. Although at higher concentration some insulin release is observed. Also, displays a wide range adenosine-dependent effects, such as blocking platelet aggregation and inhibiting DNA synthesis. When administered at reperfusion, it is shown reduce infarction and block the formation of the mitochondrial permeability transition pore by activating p70S6 kinase.

Biological Activity

Potent adenosine receptor agonist (K i values are 14, 20 and 6.2 nM for human A 1 , A 2A and A 3 receptors respectively; EC 50 = 2.4 μ M for human A 2B ). Inhibits platelet aggregation and is centrally active in vivo .
