Activation of 5-HT2A receptors using agonists at surprisingly low concentrations was shown to potently inhibit TNF-α-induced inflammation in multiple cell types. Significantly, proinflammatory markers were also inhibited by the agonist, (R)-DOI, even many hours after treatment with TNF-α. With the exception of a few natural toxins, no current drugs or small molecule therapeutics demonstrate a comparable potency for any physiological effect. TNF-α and TNF-α receptor mediated inflammatory pathways have been strongly implicated in a number of diseases, including atherosclerosis, asthma, rheumatoid arthritis, psoriasis, type II diabetes, depression, schizophrenia, and Alzheimer's disease. Importantly, because (R)-DOI can significantly inhibit the effects of TNF-α many hours after the administration of TNF-α, potential therapies could be aimed not only at preventing inflammation, but also treating inflammatory injury that has already occurred or is ongoing.
