The current study describes the synthesis and pharmacological evaluation of (E)-N-(3,7-dimethylocta-2,6-dienyl)-1,3-dimethyl-1H-pyrazol-5-amine (LQFM002), a compound originally designed through a molecular simplification strategy from 4-nerolidylcatechol. LQFM002 was evaluated for preservation of the PLA(2) enzyme inhibitory effects of the lead compound, 4-nerolidylcatechol, using
