PPAN-P2RY11 Activators

Chemical activators of PPAN-P2RY11 include a variety of agonists that engage with its P2RY11 receptor component to initiate intracellular signaling cascades. Adenosine triphosphate (ATP), the quintessential energy molecule, can directly activate PPAN-P2RY11 by binding to the P2RY11 receptor, which in turn activates the associated G-protein to kick-start downstream signaling pathways. Similarly, uridine triphosphate (UTP) and its stable analog UTPγS, by binding to the same receptor, trigger a G-protein-mediated response, indicating the receptor's responsiveness to different nucleotides. ADP, another purine nucleotide, also serves as an agonist for the P2RY11 receptor, while UDP, a pyrimidine nucleotide, engages with the same receptor, highlighting the versatility of PPAN-P2RY11 activation mechanisms. BzATP, a potent P2 receptor agonist, further underscores the protein's ability to respond to synthetic analogs of ATP, enhancing the repertoire of activating molecules.

Expanding the chemical landscape, 2-Methylthio ATP exemplifies another agonist that, despite its slight structural variation from ATP, can activate the P2RY11 receptor component of PPAN-P2RY11. Diadenosine tetraphosphate (Ap4A) showcases the protein's capacity to be modulated by dinucleotide polyphosphates, further diversifying the chemical nature of its activators. Diquafosol, though primarily associated with P2Y2 receptor activation, can also engage with P2Y11 receptors, suggesting a broader sensitivity of PPAN-P2RY11 to various purinergic molecules. Moreover, NF546 represents a selective P2Y11 agonist that specifically targets the P2RY11 receptor, reinforcing the precision with which chemical activators can modulate PPAN-P2RY11. Additionally, MRS2365, despite its selectivity for P2Y1 receptors, can interact with P2RY11 receptors, potentially influencing PPAN-P2RY11 activity. Finally, Clopidogrel, despite its primary action as an inhibitor, may exhibit off-target effects that involve PPAN-P2RY11 activation, indicating that receptor-ligand interactions can be multifaceted and not strictly limited to direct agonism.
