• Recent studies have built upon decades of evidence that adenosine, a purine nucleoside that can act as a neuromodulator, is involved in pain transmission and sensitization. (mdpi.com)
  • The adenosine A2B receptor, also known as ADORA2B, is a G-protein coupled adenosine receptor, and also denotes the human adenosine A2b receptor gene which encodes it. (wikipedia.org)
  • Research into selective A2B ligands has lagged somewhat behind the development of ligands for the other three adenosine receptor subtypes, but a number of A2B-selective compounds have now been developed, and research into their potential therapeutic applications is ongoing. (wikipedia.org)
  • BAY 60-6583 NECA (N-ethylcarboxamidoadenosine) (S)-PHPNECA - high affinity and efficacy at A2B, but poor selectivity over other adenosine receptor subtypes LUF-5835 LUF-5845 - partial agonist Compound 38: antagonist, high affinity and good subtype selectivity ISAM-R56A: non-xanthinic high affinity selective antagonist (Ki: 1.50 nM) ISAM-140: non-xanthinic selective antagonist (Ki = 3.49 nM).

  • This is further supported by the widespread use of caffeine, an adenosine receptor antagonist, in several headache treatments. (mdpi.com)
