The Influence of a Xanthine-Catechin Chemical Matrix on in vitro Macrophage-Activation Triggered by Antipsychotic Ziprasidone

Ziprasidone (ZIP) is an effective antipsychotic with low side effects than other second-generation antipsychotics. Despite this, there are reports of adverse events and previous studies associating the use of ZIP the inflammatory response. It is possible to infer that bioactive molecules present in some foods could attenuate peripheral inflammatory and oxidative stress potentially triggered ZIP. This is the case of guaraná xanthine-catechin chemical matrix (XC-Mix) that presents caffeine, theobromine, and catechin. The in vitro protocols using murine RAW 264.7 cell macrophages were ZIP-exposure in culture medium supplemented with chemical isolated and admixture of Caf, The, and Cat. Main results showed that supplementation with isolated and XC-mix had a lowering effect on 72 h macrophages proliferation. XC-mix with 1:1:1 proportion at 25 μg/mL of each caffeine, theobromine, and catechin, molecules present lowering effect on nitric oxide levels, oxidative stress markers (DNA oxidation quantified by 8-hydroxy-2′ –deoxyguanosine), lipoperoxidation, and protein carbonylation. XC-mix also decreased protein levels and downregulated genes of proinflammatory cytokines (IL-1β, IL-6, TNF-α). At contrary, XC-Mix increased levels and upregulated gene of anti-inflammatory IL-10 cytokine. The results suggest that XC-matrix could present some beneficial action on peripheral proinflammatory effects ZIP-triggered. Complementary in vivo studies could be useful to confirm these in vitro findings described here.
