ACE2 as a Target for Hydroxychloroquine/Chloroquine in COVID-19 Treatment
Five potential binding sites between HCQ/CQ and ACE2 were identified using computerized molecular docking assays. Reported values are calculated Glide Standard Precision (SP) Glide Extra Precision (XP) measurements which quantify protein/ligand interactions. These findings support the observation that HCQ is a more effective anti-SARS-CoV-2 drug than CQ in vitro because of HCQ's stronger interaction with the ACE2 allosteric site, which is involved with regulation of the receptor.
