In this in silico study, the different pharmaceutical co-crystals based on the (hydroxy)chloroquine with the macrolide antibiotics (azithromycin, clarithromycin, or erythromycin A) was analyzed for the first time. These findings present a new molecular perspective and, therefore, suggest that the combination of (hydroxy)chloroquine/azithromycin, in the stoichiometric ratio of 1:1, as model co-crystals systems have less toxicity as well as is the most effective for inhibiting the new coronavirus SARS-CoV-2.
New in silico insights into the application of the (hydroxy)chloroquine with macrolide antibiotics co-crystals against the SARS-CoV-2 virus
