Zusammenfassung:To provide compounds useful in treating disorders and diseases associated with increased level of estradiol and/or treatable by inhibition of the 17β-HSD1 enzyme, and compounds that show little or no inhibitory effect on the 17β-HSD2 enzyme.SOLUTION: The invention provides compounds of formula (I) and pharmaceutically acceptable salts thereof. (R1 and R2 are each independently H or a halogen atom; R3 is H or a C1-3 alkyl group; R4 is a C1-3 alkyl group or the like; and R3 and R4 together with the nitrogen atom to which they are attached may form a 5- or 6-membered, optionally substituted, saturated heterocycle or the like.)SELECTED DRAWING: None 【課題】エストラジオ-ルの増加したレベルに関連する障害および疾患の治療に有用で、および/または17β-HSD1酵素の阻害により治療可能な化合物を提供する。さらに、17β-HSD2酵素に対してほとんど、または全く阻害効果を示さない化合物を提供する。【解決手段】式(I)の化合物およびその薬学的に許容される塩を提供する。TIFF2024028916000233.tif44168(R1及びR2は、各々独立にH又はハロゲン原子;R3はH又は炭素原子数1乃至3のアルキル基;R4は炭素原子数1乃至3のアルキル基等;R3及びR4は、それらが結合している窒素原子とともに5乃至6員の置換可飽和複素環等を形成してもよい。)【選択図】なし
