Identification of novel formyl peptide receptor-like 1 agonists that induce macrophage tumor necrosis factor alpha production.

ABSTRACT: Development of immunomodulatory agents that enhance innate immune responses represents a promising strategy for combating infectious diseases. In the present studies, we screened a series of 71 arylcarboxylic acid hydrazide derivatives for their ability to induce macrophage tumor necrosis factor alpha (TNF-alpha) production and identified six such compounds, including one compound previously shown to be a formyl peptide receptor (FPR/FPRL1) agonist. The two most potent compounds [compound 1, nicotinic acid [5-(3-bromophenyl)-2-furyl]methylene-hydrazide; compound 2, 4-fluoro-benzoic acid [5-(3-trifluoromethyl-phenyl)-2-furyl]-methylene-hydrazide] were selected for further analysis. These compounds induced de novo production of TNF-alpha in a dose- and time-dependent manner in human and muri
