A team of scientists, co-led by researchers from the School of Life Sciences, University of Warwick, has investigated a compound called BnOCPA (benzyloxy-cyclopentyladenosine), found to be a potent and. (BnOCPA), is a potent and powerful analgesic but does not cause sedation, bradycardia, hypotension or respiratory depression. Most state programs available in January; software release dates vary by state. BnOCPA now allows us to propose a rational approach to designing G protein selective. unusual weak feeling. Scientists have investigated a compound called BnOCPA (benzyloxy-cyclopentyladenosine), found to be a potent and selective analgesic which is non-addictive in test model systems.

The discovery and clinical implementation of modulators of adenosine, P2Y and P2X receptors have progressed dramatically in ∼50 years since Burnstock's definition of purinergic signaling. However, when we investigated BnOCPA at native A 1Rs in rat hippocampal slices, against which BnOCPA is also a potent agonist, with ~8000- and >150-fold greater. 70 × 10−9). View publication. BnOCPA is unique in that it only activates one type of G protein, leading to very selective effects and thus reducing potential side effects.
