New Oxazolidines Inhibit the Secretion of IFN-γ and IL-17 by PBMCS from Moderate to Severe Asthmatic Patients

Background: Moderate to severe asthma could be induced by diverse proinflammatory cytokines, as IL-17 and IFN-gamma, which are also related to treatment resistance and airway hyperresponsiveness. Oxazolidines emerged as a novel approach for asthma treatment, since some chemical peculiarities were suggested by previous studies. Objective: The present study aimed to evaluate the IL-17A and IFN-gamma modulatory effect of two new oxazolidine derivatives (LPSF/NB-12 and -13) on mononucleated cells of patients with moderate and severe asthma. Methods: The study first looked at potential targets for oxazolidine derivatives using SWISS-ADME. After the synthesis of the compounds, cytotoxicity and cytokine levels were analyzed. Results: We demonstrated that LPSF/NB-12 and -13 reduced IFN-gamma and IL-17 production in peripheral blood mononucleated cells from asthmatic patients in a concentrated manner. Our in silico analysis showed the neurokinin-1 receptor as a common target for both compounds, which is responsible for diverse proinflammatory effects of moderate and severe asthma. Conclusion: The work demonstrated a novel approach against asthma, which deserves further studies of its mechanisms of action.
