In Silico study identifying folic acid, hispidin, and lepidine E as potential SARS-CoV-2 Mpro inhibitors.
14 preclinical studies support the efficacy of vitamin B9 for COVID-19:
Vitamin B9 has been identified by the European Food Safety Authority (EFSA) as having sufficient evidence for a causal relationship between intake and optimal immune system function12-14. Vitamin B9 inhibits SARS-CoV-2 In Silico3-11, reduces spike protein binding ability11, binds with the spike protein receptor binding domain for alpha and omicron variants2, inhibits the SARS-CoV-2 nucleocapsid protein3, inhibits 3CLpro and PLpro in enzymatic assays2, significantly reduces infection for alpha and omicron SARS-CoV-2 pseudoviruses2, and inhibits ACE2 expression and SARS-CoV-2 infection in a mouse model11.
Serseg et al., 15 Jul 2021, peer-reviewed, 3 authors.
In Silico studies are an important part of preclinical research, however results may be very different in vivo.
