Potent GPR37L1 and GPR37 agonist (EC50 values are 5 and 7 nM, respectively). Stimulates signaling through pertussis toxin-sensitive G proteins. Stimulates ERK phosphorylation. Protects against cellular stress. Promotes myelin lipid synthesis and prolongs cell survival in both Schwann cells and oligodendrocytes; neuroprotective and glioprotective.

LY294002 is a synthetic molecule inhibitor of PI3Kα/δ/β (IC50: 0.5/0.57/0.97 μM, in cell-free assays); more stable than Wortmannin in solution, and also is a blocker of autophagosome formation.

Apiin has inhibitory activity in-vitro on iNOS expression and nitrite production when added before LPS stimulation in the medium of J774.A1 cells.
