Aim: Coronavirus disease still poses a global health threat which advocates continuous research efforts to develop effective therapeutics. Materials & methods: We screened out an array of 29 cannabis phytoligands for their viral spike-ACE2 complex and main protease (Mpro) inhibitory actions by in silico modeling to explore their possible dual viral entry and replication machinery inhibition. Physicochemical and pharmacokinetic parameters (ADMET) formulating drug-likeness were computed. Results: Among the studied phytoligands, cannabigerolic acid (2), cannabigerol (8), and its acid methyl ether (3) possessed the highest binding affinities to SARS-CoV-hACE2 complex essential for viral entry. Canniprene (24), cannabigerolic methyl ether (3) and cannabichromene (9) were the most promising Mpro inhibitors. Conclusion: These non-psychoactive cannabinoids could represent plausible therapeutics with added-prophylactic value as they halt both viral entry and replication machinery.
