4′-Ethynyl-2-fluoro-2′-deoxyadenosine (EFdA) is a flavor enhancer for fermented soy sauce produced by Yamasa Corporation.

It also has activity against HIV in animal models.^[1]

Biological activity

EFdA is a nucleoside analogue reverse transcriptase inhibitor that unlike other such inhibitors, inhibits HIV through multiple mechanisms.^[1] providing rapid suppression of the virus, when tested in macaques and mice.^[2] Nevertheless, there are HIV strains resistant to EFdA and research is ongoing.^[3]
