On December 9, 2021, Perfettini, Jean-Luc; Lecuyer, Deborah; Tannous, Desiree; Allouch, Awatef; Delelis, Olivier; Subra, Frederic published a patent.Quality Control of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide The title of the patent was Modulators of purinergic receptors and related immune checkpoint for treating acute respiratory distress syndrome. And the patent contained the following:
The inventors herein show that purinergic receptors regulate the conversion of macrophage pro-inflammatory reprogramming into anti-inflammatory phenotype in patients suffering from COVID-19 disease. Moreover, they show that P2Y receptor agonists repress NLRP3 inflammasome-dependent IL-1b secretion, but also impair the replication and the cytopathogenic effects of SARS-CoV-2. These results therefore suggest that some purinergic receptors agonists can treat acute lung injury and respiratory disease that are associated with SARS-CoV-2 infection. In addition, their results show that antagonists of the purinergic receptors P2X impair the replication of said virus. The present invention therefore proposes to use purinergic receptors modulators and NLR3-P2Y2R immune checkpoint modulators to treat patients suffering from a virus-induced acute respiratory distress syndrome. The experimental process involved the reaction of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide(cas: 1428327-31-4).Quality Control of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide
