OR10H4 Inhibitors

OR10H4 inhibitors are a class of compounds that, through various mechanisms, can reduce the activity of the OR10H4 receptor, a G-protein-coupled receptor involved in olfactory signaling. Compounds like capsaicin and chlorpromazine act by altering the receptor environment or signal transduction, which can diminish the ability of OR10H4 to respond to its ligands. Capsaicin achieves this through activation of the TRPV1 receptor that can cause an increase in intracellular calcium levels, promoting phosphorylation and internalization of GPCRs like OR10H4, while chlorpromazine disrupts membrane phospholipid dynamics, potentially affecting OR10H4 localization and function. Other inhibitors such as pertussis toxin and GDP-β-S target G-proteins that are critical for OR10H4 signaling. Pertussis toxin specifically inhibits Gi/o type G-proteins through ADP-ribosylation, which impairs the ability of OR10H4 to inhibit adenylate cyclase, while GDP-β-S acts as a G-protein inhibitor by preventing GTP binding, essential for G-protein activation.

Capsaicin binds to and activates the TRPV1 receptor, which can lead to an influx of calcium ions. This increased intracellular calcium can desensitize GPCRs like OR10H4 by promoting their phosphorylation and internalization, thereby inhibiting their signaling.

Chlorpromazine interferes with dopaminergic signaling and alters membrane phospholipid metabolism. By disrupting membrane dynamics, it can inhibit GPCR function including OR10H4 by affecting its proper localization and signaling efficacy.

Haloperidol

As a dopamine receptor antagonist, haloperidol can also impact GPCR signaling. It may indirectly inhibit OR10H4 activity by altering G-protein coupling and downstream signaling cascades that OR10H4 relies on.

Pertussis Toxin (islet-activating protein)

(1)

Pertussis toxin permanently disables Gi/o proteins by ADP-ribosylation. Since OR10H4 signaling relies on Gi/o proteins to mediate inhibition of adenylate cyclase, pertussis toxin can indirectly inhibit OR10H4 signaling.

Propranolol

100 mg
$180.00
(0)

Propranolol, a beta-adrenergic receptor antagonist, can impact cAMP levels in cells. By doing so, it may indirectly inhibit OR10H4 by altering the balance of intracellular signaling pathways that control OR10H4 activity.

Wortmannin is a PI3K inhibitor that can reduce levels of PIP3, indirectly leading to a decrease in OR10H4 activity, as PIP3 is involved in the signaling pathways that regulate GPCR function.
