FIELD: medicine; pharmaceuticals and oncology.
SUBSTANCE: invention is related to isopropyl ether 5,6-dimethoxy-γ-oxobenzo[b]thiophene-2-butanoic acid of formula I, which stimulates production of human interferon-beta and has antiproliferative activity mediated by human immune cells, induction of interferon beta gene activity, activation of the STING signalling pathway. A method for preparing compound I by reacting 5,6-dimethoxy-γ-oxobenzo[b]thiophene-2-butanoic acid with anhydrous isopropyl alcohol and thionyl chloride, allowing to obtain the target compound with a yield of 85-94%, is also disclosed.
EFFECT: chemical compound and a method of its preparation are proposed.
