A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Ciclesonide (Cic) is approved as an inhalant for asthma and was clinically tested as a candidate therapy for coronavirus disease 2019 (COVID-19). Its active metabolite Cic2 was recently reported to suppress genomic RNA replication of severe acute respiratory syndrome coronavirus 2. In this study, we designed and synthesized a set of ciclesonide-acetal (Cic-acetal) derivatives. Among designated compounds, some Cic-acetal derivatives with a linear alkyl chain exhibited strong viral copy-number reduction activities compared with Cic2. These compounds might serve as lead compounds for developing novel anti-COVID-19 agents.
