Zusammenfassung:PROBLEM TO BE SOLVED: To provide a microphthalmia-associated transcription factor inhibiting agent, a melanogenesis inhibiting agent, a cosmetic composition and an anticancer agent, which comprise an edible plant-derived component, exhibit microphthalmia-associated transcription factor inhibitory action and have more excellent melanogenesis inhibitory action than before.SOLUTION: Each agent contains an alicyclic compound represented by the formula (1A) or (1B). In the formula (1A) or (1B), Rand Rare each independently a hydrocarbon group which may have a hydrogen, a hydroxyl group or a substituent, and in addition, one of the two adjacent chemical bonds shown by dotted lines is a double bond. 【課題】食用植物由来の成分を含むとともに、小眼球症関連転写因子抑制作用を示し、従来よりもメラニン産生抑制作用に優れた小眼球症関連転写因子抑制剤、メラニン産生抑制剤、化粧品組成物及び抗ガン剤を提供する。【解決手段】各薬剤において、下記式(1A)又は(1B)で示される脂環式化合物を含有するものとする。下記式(1A)又は(1B)において、R1、R2は、それぞれ独立に、水素、ヒドロキシル基又は置換基を有していてもよい炭化水素基である。また、点線で示されている隣接する2つの化学結合のうち、一方が二重結合である。【選択図】図2
