2 non-hydrolysable derivatives of adenosine triphosphate failed to alter the mean number of acetylcholine ( ach ) quanta released by the nerve impulse ( m ) or the miniature endplate potential frequency ( m.e.p.p.f ) but n6-methyladenosine and 2-chloroadenosine , two adenosine analogues with an unsubstituted ribose moiety ( r-site agonists ) , produced marked reductions in m and m.e.p.p.f .
