caffeic

This paper speculated that caffeic acid binds to ACE2 and inhibits viral attachment and infection via this route.

Regarding caffeic acid, it’s possible that it may have different effects based on concentration and other conditions.

Coffee is an anti-thiamine factor (because of compounds like caffeic acid, which also exist in Dcaf).

It utilizes the bioluminescence pathway from a fungus that uses caffeic acid to generate light.

Aspartame is interesting in that unlike caffeic acid, it's a newly-introduced substance that saw rapid, widespread adoption in the mass market.

As are caffeic acid (found in coffee, wine, mint), aloe vera and pickled vegetables.

If I start to come down with it, I think I'm going to do a 500 mg caffeic acid dose.

Some other papers state less caffeic acid and less quinic acid.

Looking at the list of group 2B carcinogen, I see things like caffeic acid (common in food like, uh, coffee, but other things as well).

I read a paper that suggested caffeic acid was the anti-viral component of elderberry extract that was actually inhibiting HCoV-NL63 viral attachment and infection of human lung cells in vitro (Virus Research, 273 (2019)197767).

The common caffeinated dietary, e.g., coffee or tea, contains several other biocompounds (such as chlorogenic acid, caffeic acid, trigonelline, kahweol, and cafestol83) which may provide other neuroprotective effects.

Decaf works too: Three instant coffee extracts (light roast, dark roast, decaffeinated dark roast) and six coffee components [caffeine (1), chlorogenic acid (2), quinic acid (3), caffeic acid (4), quercetin (5), and phenylindane (6)] were investigated for their ability to inhibit the fibrillization of Aβ and tau proteins using thioflavin T (ThT) and thioflavin S (ThS) fluorescence assays, respectively.

Caffeic acid may be a carcinogen but I do not think any decent studies have found a connection between drinking coffee and cancer, and in fact some have found the opposite.
