Libosch., which belongs to the Orobanchaceae family, is a perennial herb found in China, Japan, and Korea. In traditional medicine, it is used to cool the body, improve water metabolism in the kidney, and provide protection from metabolic diseases such as type 2 diabetes mellitus (T2DM) and obesity. In this study, three new compounds were isolated from the roots of , along with eighteen known compounds. Structure elucidation was performed with spectroscopic analyses including nuclear magnetic resonance (NMR) and circular dichroism (CD) spectroscopy. As the AMP-activated protein kinase (AMPK) signaling pathway is reportedly related to metabolic diseases, AMPK activation studies were conducted using in silico simulations and in vitro assays. Among the isolated compounds, showed a potential as an AMPK activator in both in silico simulations and in vitro experiments. Our findings expand the chemical profiles of the plant and suggest that one newly found compound () activates AMPK.

Introduction: Triple-negative breast cancer (TNBC) is the most challenging subtype of breast cancer to treat. While previous studies have demonstrated that ginsenoside Rh2 induces apoptosis in TNBC cells, the specific molecular targets and underlying mechanisms remain poorly understood. This study aims to uncover the molecular mechanisms through which ginsenoside Rh2 regulates apoptosis and proliferation in TNBC, offering new insights into its therapeutic potential.

We previously reported that metformin, a widely prescribed antidiabetic drug, induces the accumulation of triglyceride (TG) together with the apoptotic death of H4IIE via AMP-activated protein kinase (AMPK) in hepatocellular carcinoma (HCC) cells. However, the effect of cytoplasmic fat accumulation on the growth of HCCs remains controversial. Herein, we investigated the effect of fatty acid synthase (FASN) inhibitors on the basal- or metformin-induced changes including the content of cytoplasmic TG and the viability of HCC cells.

Background: Oily skin not only threatens people with aesthetic and hygienic discomfort but also confronts them with annoying skin problems. To explore new skin care ingredients from herbal or plant extracts and understand their underlying mechanism for sebum control would assist in the discovery of desirable sebosuppressive agents, though it is still a deserving and challenging task.
Aim: To explore the effect of Camellia saponin (CS) on modulating the lipogenesis of human sebocytes.

Atherosclerosis, a chronic inflammatory condition characterized by plaque formation, often leads to instability, particularly under Type 2 diabetes mellitus (T2DM) conditions, which exacerbate cardiovascular risks. However, the molecular mechanisms underlying this process remain incompletely understood. In this study, we investigated the correlation between acute coronary syndrome (ACS) and serum levels of Nε-carboxyethyl-lysin (CEL), a prominent advanced glycation end product (AGE) elevated in T2DM, in a cohort of 225 patients with coronary artery disease.
