The human skin, the body's largest organ, undergoes continuous renewal but is significantly impacted by aging, which impairs its function and leads to visible changes. This study aimed to identify botanical compounds that mimic the anti-aging effects of baricitinib, a known JAK1/2 inhibitor. Through in silico screening of a botanical compound library, 14 potential candidates were identified, and 7 were further analyzed for their effects on cellular aging. The compounds were tested on both normal aged fibroblasts and premature aging fibroblasts derived from patients with Hutchinson-Gilford Progeria Syndrome (HGPS). Results showed that these botanical compounds effectively inhibited the JAK/STAT pathway, reduced the levels of phosphorylated STAT1 and STAT3, and ameliorated phenotypic changes associated with cellular aging. Treatments improved cell proliferation, reduced senescence markers, and enhanced autophagy without inducing cytotoxicity. Compounds, such as Resveratrol, Bisdemethoxycurcumin, Pinosylvin, Methyl P-Hydroxycinnamate, cis-Pterostilbene, and (+)-Gallocatechin, demonstrated significant improvements in both control and HGPS fibroblasts. These findings suggest that these botanical compounds have the potential to mitigate age-related cellular alterations, offering promising strategies for anti-aging therapies, particularly for skin health. Further in vivo studies are warranted to validate these results and explore their therapeutic applications.
人体皮肤是身体最大的器官,不断进行更新,但会受到衰老的显著影响,导致其功能受损并出现可见的变化。本研究旨在鉴定模仿巴瑞替尼(一种已知的 JAK1/2 抑制剂)抗衰老作用的植物化合物。通过对植物化合物库进行计算机筛选,确定了 14 种潜在的候选化合物,进一步分析了其中 7 种化合物对细胞衰老的影响。在正常老化的成纤维细胞和源自亨廷顿舞蹈病患者的过早老化成纤维细胞(HGPS)中测试了这些化合物。结果表明,这些植物化合物可有效抑制 JAK/STAT 途径,降低磷酸化 STAT1 和 STAT3 的水平,并改善与细胞衰老相关的表型变化。治疗可改善细胞增殖,减少衰老标志物,增强自噬,而不会诱导细胞毒性。白藜芦醇、双去甲氧基姜黄素、松脂素、对羟基肉桂酸甲酯、顺式-对甲氧基二苯乙烯和(+)-没食子儿茶素等化合物可显著改善对照和 HGPS 成纤维细胞的状况。这些发现表明,这些植物化合物具有减轻与年龄相关的细胞改变的潜力,为抗衰老疗法,特别是皮肤健康提供了有前途的策略。有必要进行进一步的体内研究来验证这些结果并探索它们的治疗应用。
