    • Provided are anti-wrinkle agents having a novel scaffold that is suitable as components for external skin preparations such as cosmetics. The anti-wrinkle agents comprise compounds represented by general formula (1), stereoisomers thereof, or pharmacologically acceptable salts thereof. Said anti-wrinkle agents have excellent efficacy in improving wrinkles and sagging that are caused by skin aging with increased age or occur as a result of photoaging due to ultraviolet rays exposure. [In the formula, R1 represents a hydrogen atom or a 1 to 8 carbon straight or branched alkyl group. R2 represents —SH, —SO3H, —S—S—X1, —S—X2, —SO—X3, —SO2—X4, —SO2—NY1—X5 or —SO2—NY2—Y3. X1-X5 independently are hydrogen atoms or 1 to 8 carbon aliphatic hydrocarbon groups or 5 to 12 carbon aromatic moiety wherein carbon atoms may be substituted with heteroatoms. Y1 to Y3 independently represent hydrogen atoms or 1 to 8 carbon linear or branched alkyl groups. R3 represents a hydrogen atom or acyl group having a 1 to 8 carbon straight or branched alkyl chain. R4 represents a 5 to 12 carbon aromatic group or polycyclic condensed aromatic group that may have unsubstituted or substituted groups. m represents an integer 0-3 and n represents an integer 1 or 2].
    • 提供了具有适合作为外用皮肤制剂如化妆品的组分的新型支架的抗皱剂。 抗皱剂包括由通式(1)表示的化合物,其立体异构体或其药理学上可接受的盐。 所述抗皱剂在改善由老化引起的皱纹和下垂的作用方面具有优异的效果,或者由于紫外线暴露引起的光老化而发生。 [式中,R 1表示氢原子或1〜8碳直链或支链烷基。 R2表示-SH,-SO3H,-S-S-X1,-S-X2,-SO-X3,-SO2-X4,-SO2-NY1-X5或-SO2-NY2-Y3。 X 1 -X 5独立地是氢原子或1至8个碳脂族烃基或5至12个碳芳族部分,其中碳原子可以被杂原子取代。 Y 1〜Y 3独立地表示氢原子或1〜8个碳直链或支链烷基。 R3表示氢原子或具有1-8个碳直链或支链烷基链的酰基。 R 4表示可以具有未取代或取代基的5〜12个碳芳香族基团或多环稠合芳香族基团。 m表示0-3的整数,n表示1或2的整数]。
