Cancer Science, EarlyView.Schematic pathway diagram illustrating the effects of JI‐CJ002 and dabrafenib on melanoma progression. The combination of JI‐CJ002 and dabrafenib is associated with reduced B7‐H3 expression and modulation of signaling pathways implicated in melanoma progression, including JAK2/STAT3, PI3K/AKT/mTOR, and Rb/E2F1.

Human Tyrosinase Inhibitor in Rum Distillate Wastewater
Journal of Oleo Science, 2008 An inhibitor of human tyrosinase activity in rum distillate wastewater was isolated and identified as (S)-(+)-imperanene (1). (S)-(+)-Imperanene significantly inhibited tyrosinase isolated from HMV-II cells (IC(50) 1.85 mM). Inhibition kinetics studies revealed that imperanene is a competitive inhibitor of tyrosinase when L-3,4-dihydroxyphenylalanine ...

The research on tyrosinase inhibition and biological activity of cinnamaldehyde and its derivatives [PDF]
, 2016 酪氨酸酶（EC1.14.18.1）是一种含铜的氧化还原酶，广泛分布于微生物，动物，植物和人体中，是生物体生命活动的关键酶。若人体中酪氨酸酶异常表达能引起雀斑和黑色素沉积等皮肤病，且其在昆虫的蜕皮及果蔬褐变中起了关键的作用，因此酪氨酸酶抑制剂的研究引起了广泛的关注。肉桂醛主要存在于天然樟科植物桂皮中，在农业、医药上具有重要的作用。 本文首先以蘑菇酪氨酸酶为对象，研究了肉桂醛及其α位C上取代的三种衍生物：α-溴代肉桂醛、α-氯代肉桂醛和α-甲基肉桂醛对酶的抑制作用，结果表明四者抑制50%单酚酶活性的浓度 ...

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin
International Journal of Cosmetic Science, EarlyView.Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but
