Cetylpyridinium chloride (CPC), a quaternary ammonium compound, which is present in mouthwash, is effective against bacteria, fungi, and enveloped viruses. This study was conducted to explore the antiviral effect of CPC on SARS-CoV-2. There are few reports on the effect of CPC against wild-type SARS-CoV-2 at low concentrations such as 0.001%-0.005% (10-50 µg/mL). Interestingly, we found that low concentrations of CPC suppressed the infectivity of human isolated SARS-CoV-2 strains (Wuhan, Alpha, Beta, and Gamma) even in saliva. Furthermore, we demonstrated that CPC shows anti-SARS-CoV-2 effects without disrupting the virus envelope, using sucrose density analysis and electron microscopic examination. In conclusion, this study provided experimental evidence that CPC may inhibit SARS-CoV-2 infection even at lower concentrations.
氯化十六烷基吡啶（CPC）是一种季铵化合物，存在于漱口水中，对细菌、真菌和包膜病毒有效。本研究旨在探索 CPC 对 SARS-CoV-2 的抗病毒作用。目前，关于 CPC 在低浓度（如 0.001%-0.005%，即 10-50μg/mL）下对野生型 SARS-CoV-2 的作用的报道较少。有趣的是，我们发现低浓度的 CPC 抑制了人分离的 SARS-CoV-2 株（武汉株、Alpha、Beta 和 Gamma）的感染力，即使在唾液中也是如此。此外，我们还通过蔗糖密度分析和电子显微镜检查证明，CPC 具有抗 SARS-CoV-2 作用，而不会破坏病毒包膜。总之，本研究提供了实验证据，表明 CPC 即使在较低浓度下也可能抑制 SARS-CoV-2 的感染。
