The present invention relates to compounds useful for detecting the activity of human aldoketoreductase 1Cs, compounds useful for competitively inhibiting human aldoketoreductase 1Cs and compounds useful for treating human aldoketoreductase 1C-related cancers, as well as pharmaceutical compositions and methods of manufacture thereof.
A process for regioselectively producing a lignan compound of general formula (I) by reacting a lactone compound of general formula (II) with a compound of the formula: R⁷Cl (R⁷ being a tri(lower alkyl)silyl group) in the presence of a base, effecting the addition reaction of an acetylene compound of general formula (III) with the resultant compound, and reducing the product. In said formulas R¹ represents alkyl, cycloalkyl, cycloalkyl-lower alkyl, aralkyl, etc.: R² and R³ each represent lower alkoxy, etc.; R⁴ represents lower alkoxy or hydrogen; and R⁵ and R⁶ each represent lower alkyl.
