P2X Receptor Activator

HEI3090 is a P2X7R activator. HEI3090 stimulates dendritic cells expressing P2X7R to produce IL-18, which subsequently promotes Natural Killer cells and CD4 T cells within tumors to produce IFN-γ, leading to a sustained antitumor response. HEI3090 can be used to enhance the efficacy of αPD-1 therapy in non-small cell lung cancer (NSCLC).

2-Methylthio-ATP tetrasodium is a non-specific P2-receptor agonist. 2-Methylthio-ATP tetrasodium causes noncompetitive inhibition of ADP-induced human platelet aggregation.

MRS2339 is a ribose-modified nucleotide and a nucleotidase-resistant P2 receptor agonist. MRS2339 activates P2X4R. MRS2339 induces ionic currents via P2X receptors, reduces cardiomyocyte cross-sectional area and heart weight/body weight ratio, lacks vasodilatory activity, and extends the lifespan of mice with cardiomyopathy. MRS2339 can be used in research related to heart failure and cardiomyopathy.

Diadenosine pentaphosphate (Ap5A; P1,P5-Di(adenosine-5'-)pentaphosphate) is an endogenous generated diadenosine polyphosphate, possessing the dual identities of intracellular alarm signal and extracellular signaling molecule. Diadenosine pentaphosphate regulates calcium signaling in the nervous, cardiac and peripheral sensory systems by activating P2X1/P2X3/P2Y receptor and RyR2 channels (EC₅₀ = 140 μM). Diadenosine pentaphosphate can be used in studies related to intracellular calcium release channels, cardiovascular diseases and nociception (pain).
