The present invention provides an agent for preventing and alleviating wrinkles which has excellent effects of preventing and alleviating wrinkles formed by decreased barrier function of the skin owing to aging or photo aging, that is graphic wrinkles or linear wrinkles.
The agent for preventing and alleviating wrinkles consisting of one or more compounds selected from the group consisting of gamma-aminobutyric acid derivatives represented by the following formula (1) or N,N,N-trimethyl gamma-aminobutyric acid represented by the following formula (3) and salts thereof:
wherein R1 and R2 independently represent any of a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, a benzyloxycarbonyl group, a cyclohexyl group, a cyclohexanemethyl group, a cyclohexanecarbonyl group, a guanidino group formed with nitrogen atom in the formula (1), an ureido group formed with nitrogen atom in the formula (1), and a group represented by following formula (2). Additionally, R1 and R2 may jointly form a piperidine ring, morpholine ring, or pyrrolidine ring. Both of R1 and R2 are not simultaneously a hydrogen atom.
本发明提供了一种用于预防和减轻皱纹的药剂,该药剂对预防和减轻由于老化或光老化导致皮肤屏障功能降低而形成的皱纹(即图形皱纹或线性皱纹)具有极佳的效果。
这种预防和缓解皱纹的制剂由一种或多种化合物组成,这些化合物选自由下式(1)代表的γ-氨基丁酸衍生物或下式(3)代表的N,N,N-三甲基γ-氨基丁酸及其盐组成的组:
其中,R1 和 R2 独立地代表氢原子、具有 1 至 3 个碳原子的烷基、苄氧羰基、环己基、环己基甲基、环己基羰基、与式(1)中氮原子形成的胍基、与式(1)中氮原子形成的脲基以及下式(2)所代表的基团中的任意一种。此外,R1 和 R2 可共同形成哌啶环、吗啉环或吡咯烷环。R1 和 R2 不能同时为氢原子。
