OR13F1 Activators

Isoproterenol, rolipram, and zaprinast have a role in the regulation of cyclic nucleotide levels within the cell. Isoproterenol, as a beta-adrenergic receptor agonist, can promote the production of cAMP, subsequently influencing GPCR signaling pathways. Rolipram and zaprinast, by inhibiting PDE4 and PDE5 respectively, prevent the breakdown of cAMP and cGMP, leading to sustained signaling that can intersect with the pathways OR13F1 might utilize. Other molecules such as histamine, carbachol, and nicotine exert their effects via receptor-mediated actions. Histamine, by activating its own set of GPCRs, can alter the intracellular signaling milieu, potentially impacting OR13F1 activity. Carbachol and nicotine, acting through cholinergic and nicotinic receptors respectively, can cause changes in cAMP levels and downstream signaling that could influence OR13F1.

Moreover, compounds like capsaicin, adenosine, and norepinephrine modulate the activity of other GPCRs or ion channels, creating a cascade of intracellular events. Capsaicin's activation of TRPV1 could lead to intracellular pathways that modulate GPCR signaling. Adenosine and norepinephrine, through their respective receptors, can influence cAMP levels, thus potentially modulating the activity of OR13F1. Glutamate, Adenosine 5'-Triphosphate, disodium salt, and ionomycin impact intracellular calcium levels, a key component in GPCR signaling. Glutamate's action on metabotropic receptors and ATP's effect on purinergic receptors can lead to increased calcium levels. Ionomycin directly increases intracellular calcium by acting as an ionophore. These changes in calcium dynamics can affect GPCR activity, including the signaling pathways associated with OR13F1.
