N-Boc-Phe-Leu-Phe-Leu-Phe (Boc-FLFLF) is a formyl peptide receptor 1 (FPR1) antagonist, which increases pain effects and inhibits antinociceptive activity of annexin. Boc-Phe-Leu-Phe-Leu-Phe is used extensively in FPR research.

Misonidazole as a novel GPX inhibitors to cause oxidative stress in chemotherapy-resistant tumors.

Heliosupine, heliosupine N-oxide, 3 ′-O-acetylheliosupine N-oxide,and 7-O- angeloylechinatine N-oxide show inhibition activity against the acetylcholinesterase(AChE), with IC50 0.53-0.60 mM. Heliosupine can deter feeding by the polyphagous larvae of Spodoptera exigua.
