Background:

Merafloxacin (CI-934), a fluoroquinolone antibacterial agent, is a selective programmed -1 ribosomal frameshifting (-1 PRF) inhibitor of beta coronaviruses. Merafloxacin exhibits in vitro activity against gram-positive and gram-negative bacteria[1][2].

Merafloxacin (5-80 μM) dose-dependently inhibits programmed -1 ribosomal frameshifting (-1 PRF) of SARS-CoV-2, SARS-CoV, hCoVO-C43, and hCoV-HKU1, with IC50s of 19.6 μM, 19.5 μM, 29.7 μM, and 38.6 μM, respectively[1].
