Fig. 7From: Umbelliferone and eriodictyol suppress the cellular entry of SARS-CoV-2Schematics of the working model of umbelliferone and eriodictyol in inhibiting SARS-CoV-2 infection. Umbelliferone and eriodictyol attenuate the enzymatic activities of furin and TMPRSS2, which cleaves and primes SARS-CoV-2 spike protein, suppressing the cellular entry of SARS-CoV-2 variants.
