Curcumin for COVID-19
15th treatment shown to reduce risk in February 2021
 
*, now with p = 0.0000000096 from 27 studies.
No treatment is 100% effective. Protocols combine treatments. * >10% efficacy, ≥3 studies.
4,500+ studies for 81 treatments. c19early.org
In Silico study showing that curcumin strongly inhibits the interaction between the SARS-CoV-2 spike protein receptor binding domain (RBD) and the human ACE2 receptor for the delta and omicron variants. Molecular docking and dynamics simulations revealed curcumin's higher binding efficiency compared to other lead compounds, which may be due to spike protein mutations altering the RBD structure and ACE2 interactions.
45 preclinical studies support the efficacy of curcumin for COVID-19:
In Silico studies predict inhibition of SARS-CoV-2 with curcumin or metabolites via binding to the spikeA,5,10,12,18,21 (and specifically the receptor binding domainB,8,11,14), MproC,5,7,9-11,13,14,16,19,21,22,24,35, RNA-dependent RNA polymeraseD,11,20, ACE2E,12,13,15, nucleocapsidF,6,23, nsp10G,23, and helicaseH,25 proteins. In Vitro studies demonstrate inhibition of the spikeA,30 (and specifically the receptor binding domainB,38), MproC,17,30,35,37, ACE2E,38, and TMPRSS2I,38 proteins. In Vitro studies demonstrate efficacy in Calu-3J,36, A549K,30, 293TL,1, HEK293-hACE2M,17,28, 293T/hACE2/TMPRSS2N,29, Vero E6O,7,11,21,28,30-32,34,36, and SH-SY5YP,27 cells. Curcumin is predicted to inhibit the interaction between the SARS-CoV-2 spike protein receptor binding domain and the human ACE2 receptor for the delta and omicron variants8, decreases pro-inflammatory cytokines induced by SARS-CoV-2 in peripheral blood mononuclear cells34, and alleviates SARS-CoV-2 spike protein-induced mitochondrial membrane damage and oxidative stress1.

In Silico studies are an important part of preclinical research, however results may be very different in vivo.
