Selective medium-chain free fatty acid receptor GPR84 agonist (EC50 = 139 nM). Exhibits no response at GPR40, GPR41, GPR119 or GPR120 at 100 μM. Activates calcium mobilization, inhibits cAMP accumulation, and induces ERK1/2 phosphorylation, receptor desensitization and internalization in vitro.

JAMI1001A is a positive allosteric modulator of the AMPA receptor, effectively modulating the deactivation and desensitization of both flip and flop receptor isoforms.
RO5126946 is a Novel α7 nicotinic acetylcholine receptor-positive allosteric modulator. RO5126946 allosterically modulates α7nAChR activity. RO5126946 increased acetylcholine-evoked peak current and delayed current decay but did not affect the recovery of α7nAChRs from desensitization. In addition, RO5126946's effects were absent when nicotine-evoked currents were completely blocked by coapplication of the α7nAChR-selective antagonist methyl-lycaconitine.
Rediocide A, an insecticide, can inhibit calcium mobilization in Drosophila G-protein- coupled receptors (GPCR)s other than methuselah, it can induce GPCR desensitization and internalization, and such effects are mediated by the activation of conventional
