Ribose-based nucleoside 5'-diphosphates and triphosphates and related nucleotides were compared in their potency at the P2Y receptors with the corresponding nucleoside 5'-phosphonate derivatives. Phosphonate derivatives of UTP and ATP activated the P2Y(2) receptor but were inactive or weakly active at P2Y(4) receptor. Uridine 5'-(diphospho)phosphonate was approximately as potent at the P2Y(2) receptor as at the UDP-activated P2Y(6) receptor. These results suggest that removal of the 5'-oxygen at ...[more]
