Development of ciclesonide analogues that block SARS-CoV-2 RNA replication.
Ontology highlight
ABSTRACT: Ciclesonide is an inhaled corticosteroid used to treat asthma and is currently undergoing clinical trials for treatment of coronavirus disease 2019 (COVID-19). An active metabolite of ciclesonide, Cic2, was recently reported to repress severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genomic RNA replication. Herein, we designed and synthesized a few types of ciclesonide analogues. Cic4 (bearing an azide group) and Cic6 (bearing a chloro group) potently decreased SARS-CoV-2 viral replication and had low cytotoxicity compared with Cic2 (bearing a hydroxy group). These compounds are promising as novel therapeutic agents for COVID-19 that show significant antiviral activity.
