31179460-6	2019	Fractionation by ultra-filtration and sequential liquid-liquid extraction showed that the compounds responsible for the inhibition are water-soluble with low molecular weights (<3 kDa) and that action could be through the following five compounds: ergothioneine, adenine, guanine, hypoxanthine, and xanthine, which are present in all fractions (UF-3, AqF-3 kDa and organic fractions) showing NS3/4A inhibition.	Ergothioneine	248-261	KRAS proto-oncogene, GTPase	Homo sapiens	392-395
