Synthesis and Structure-Activity Relationships of Pyridoxal-6-arylazo-5'-phosphate and Phosphonate Derivatives as P2 Receptor Antagonists. [PDF]
, 1998 Novel analogs of the P2 receptor antagonist pyridoxal-5'-phosphate-6-phenylazo-2',4'-disulfonate (PPADS) were synthesized. Modifications were made through functional group substitution on the sulfophenyl ring and at the phosphate moiety through the ...

Respiratory Research, 2005 Background Uridine 5'-triphosphate (UTP) and uridine 5'-diphosphate (UDP) act via P2Y receptors to evoke contraction of rat pulmonary arteries, whilst adenosine 5'-triphosphate (ATP) acts via P2X and P2Y receptors.

Resetting intrinsic purinergic modulation of neural activity: an associative mechanism? [PDF]
, 2002 The purines, ATP and adenosine, control the rundown and termination of swimming in the Xenopus embryo. This intrinsic purinergic modulation, unavoidably present during every swimming episode, could lead to stereotyped inflexible behavior and consequently

P2Y11 Purinoceptor Mediates the ATP-Enhanced Chemotactic Response of Rat Neutrophils
Journal of Pharmacological Sciences, 2012 ATP and hydrolysis products of ATP like adenosine regulate the chemotaxis of neutrophils by activating purinoceptors and adenosine receptors. The present study was designed to examine exogenous ATP, activation of purinoceptors, and activation of A3 ...

Frontiers in Physiology, 2021 Urothelial cells have been implicated in bladder mechanosensory transduction, and thus, initiation of the micturition reflex. Cell deformation caused by tension forces at an air-liquid interface (ALI) can induce an increase in intracellular Ca2 ...

P2Y Receptor-Mediated Ca2+ Signaling Increases Human Vascular Endothelial Cell Permeability
Journal of Pharmacological Sciences, 2004 We investigated the effects of P2-receptor agonists on cell size, intracellular calcium levels ([Ca2+]i), and permeation of FITC-labeled dextran (FD-4) as well as the relationship between these effects in human umbilical vein endothelial cells (HUVEC ...

Constant rank bimatrix games are PPAD-hard [PDF]
Proceedings of the forty-sixth annual ACM symposium on Theory of computing, 2014 The rank of a bimatrix game (A,B) is defined as rank(A+B). Computing a Nash equilibrium (NE) of a rank-$0$, i.e., zero-sum game is equivalent to linear programming (von Neumann'28, Dantzig'51). In 2005, Kannan and Theobald gave an FPTAS for constant rank games, and asked if there exists a polynomial time algorithm to compute an exact NE.

Frontiers in Cellular Neuroscience, 2018 Previous studies suggested that the thrombospondin-1/transforming growth factor-β1 (TSP-1/TGF-β1) pathway might be critical in synaptogenesis during development and that the purinergic P2 receptor family could regulate synaptogenesis by modulating TSP-1 ...

Detrusor overactivity induced by intravesical application of adenosine 5 '-triphosphate under different delivery conditions in rats [PDF]
, 2005 Objectives. We investigate the effects of intravesical application of adenosine 5'-triphosphate (ATP) on bladder activity to elucidate the role of urothelial barrier function and ecto-ATPase activity in the ATP-mediated mechanism inducing detrusor ...
