Cannabinoids as Emergent Therapy Against COVID-19

/by

The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory distress syndrome coronavirus 2(SARS-Cov-2), was identified for the first time in late 2019 in China, resulting in a global pandemic of massiveimpact. Despite a fast development and implementation of vaccination strategies, and the scouting of severalpharmacological treatments, alternative effective treatments are still needed. In this regard, cannabinoids repre-sent a promising approach because they have been proven to exhibit several immunomodulatory, anti-inflammatory, and antiviral properties in COVID-19 disease models and related pathological conditions. Thismini-review aims at providing a practical brief overview of the potential applications of cannabinoids so far iden-tified for the treatment and prevention of COVID-19, finally considering key aspects related to their technologicaland clinical implementation.

Anti-Inflammatory and Antiviral Effects of Cannabinoids in Inhibiting and Preventing SARS-CoV-2 Infection

/by

The COVID-19 pandemic caused by the SARS-CoV-2 virus made it necessary to search for new options for both causal treatment and mitigation of its symptoms. Scientists and researchers around the world are constantly looking for the best therapeutic options. These difficult circumstances have also spurred the re-examination of the potential of natural substances contained in Cannabis sativa L. Cannabinoids, apart from CB1 and CB2 receptors, may act multifacetedly through a number of other receptors, such as the GPR55, TRPV1, PPARs, 5-HT1A, adenosine and glycine receptors.

Cannabidiol Inhibits SARS-CoV-2 Replication and Promotes the Host Innate Immune Response

/by

The rapid spread of COVID-19 underscores the need for new treatments. Here we report that cannabidiol (CBD), a compound produced by the cannabis plant, inhibits SARS-CoV-2 infection. CBD and its metabolite, 7-OH-CBD, but not congeneric cannabinoids, potently block SARS-CoV-2 replication in lung epithelial cells. CBD acts after cellular infection, inhibiting viral gene expression and reversing many effects of SARS-CoV-2 on host gene transcription. CBD induces interferon expression and up-regulates its antiviral signaling pathway.
