potential of synthetic isoflavones for application in cosmeceuticals. Twenty‐five isoflavones were synthesized and their capacities of free‐radical‐scavenging and mushroom tyrosinase inhibition, as well as their impact on cell viability of B16F10 murine melanoma cells and HaCaT human keratinocytes were evaluated. Isoflavones that showed significant mushroom tyrosinase inhibitory activities were further
在这项研究中,我们研究了合成异黄酮在药妆品中的应用潜力。合成了 25 种异黄酮,并评估了它们清除自由基和抑制蘑菇酪氨酸酶的能力,以及它们对 B16F10 鼠黑色素瘤细胞和 HaCaT 人角质形成细胞的细胞活力的影响。进一步研究了显示出显着蘑菇酪氨酸酶抑制活性的异黄酮在体外 B16F10 黑素细胞中减少细胞黑色素形成和抗酪氨酸酶活性。在测试的异黄酮中,6-羟基黄豆苷元 (2) 是 ABTS.+ 和 DPPH 的最强清除剂。SC50 值分别为 11.3±0.3 和 9.4±0.1 μM 的自由基。Texasin (20) 表现出最有效的蘑菇酪氨酸酶抑制作用 (IC50 14.9±4.5 μM),而 retusin (17) 分别显示出对 B16F10 黑素细胞中细胞黑色素形成和抗酪氨酸酶活性的最有效抑制。总之,retusin (17) 和 texasin (20) 都表现出强大的自由基清除能力
