Article Title: Mechanisms of antiviral action and toxicities of ipecac alkaloids: Emetine and dehydroemetine exhibit anti-coronaviral activities at non-cardiotoxic concentrations

Figure Lengend Snippet: Antiviral activity and selectivity of ipecac alkaloids toward HCoV-OC43 virus in Vero E6 cells. A – Emetine, or an analog, was introduced after absorption of HCoV-OC43 (MOI 20). Viral RNA in the medium 72 h following infection was isolated and viral growth was evaluated by RT-qPCR for the N-gene. B - Non-infected Vero E6 cells were exposed to ipecac alkaloids for 72 h followed by MTS assay to evaluate growth inhibition and toxicity in response to drugs. Experimental details are described in Materials and Methods. Filled circles – emetine; empty circles – DHE4; filled squares – DHE2; empty squares – isoemetine; filled diamonds – DHE1; empty diamonds – DHE3.
Article Snippet: Viral genome copy number was determined by reverse transcription coupled with quantitative PCR (RT-qPCR) using Quantitative Genomic RNA from Betacoronavirus 1 Strain OC43 (ATCC; VR-1558DQ) as a standard.
