Nigella sativa L. as a Potential Phytotherapy for COVID-19: A Mini-Review of In-silico Studies
Słowa kluczowe
Abstrakcyjny
Background: Coronaviruses are responsible for several human diseases such as the pandemic infectious disease 2019 (COVID-19) which is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Nigella sativa (NS) is a natural food supplement with a known safety profile that may provide a wealth of known antiviral compounds.
Objective: To explore the studies supporting the NS potential for hitting SARS-CoV-2 targets.
Methods: A literature search for scientific published or preprint in-silico studies between 1990 and 2020 in electronic databases (PubMed, Science Direct, Scopus, and Google Scholar) was performed for the terms Nigella sativa, black seed, coronavirus, SARS-CoV-2 and COVID-19.
Results: At least eight in-silico studies have shown that some compounds of NS, including Nigelledine, α-Hederin, Hederagenin, Thymohydroquinone, and Thymoquinone, had high to moderate affinity with SARS-CoV-2 enzymes and proteins. These compounds may potentially inhibit SARS-CoV-2 replication and attachment to host cell receptors.
Conclusions: These preliminary data propose NS as a potential phytotherapy candidate for COVID-19. Further preclinical experimental evidence is required followed by a phase 1 clinical trial.
Keywords: COVID-19; Coronavirus; In-silico; Nigella sativa; SARS-CoV-2.
