Structure−Activity Relationship Studies on N′-Aryl Carbohydrazide P2X7 Antagonists
摘要:
N'-Aryl acyl hydrazides were identified as P2X(7) receptor antagonists. Structure-activity relationship (SAR) studies evaluated functional activity by monitoring calcium flux inhibition in cell lines expressing recombinant human and rat P2X(7) receptors. Selected analogs were assayed in vitro for their capacity to inhibit release of cytokine IL-1 beta. Compounds with potent antagonist function were evaluated in vivo using the zymosan-induced peritonitis model. A representative compound effectively attenuated mechanical allodynia in a rat model of neuropathic pain.
