Study on the Chemical Constituents, Pharmacological Activities, and Clinical Application of Taxus.
Taxus, a rare and protected genus predominantly distributed across the Northern Hemisphere's temperate regions, has garnered global attention due to its significant potential in medical research and pharmaceutical development, bolstered by advancements in cultivation techniques and medical technology. This review primarily focuses on the chemical constituents and pharmacological activities of Taxus, underscoring the progress and potential of these components in clinical applications. Recent studies have revealed that Taxus contains not only taxane active components but also flavonoids and polysaccharides with distinct activities. ⋯ Finally, this review summarizes the pharmacokinetic characteristics of crucial compounds in Taxus, including their absorption, distribution, metabolism, and excretion patterns in the human body. These pharmacokinetic profiles provide crucial guidance for evaluating the overall dosing regimen of Taxus and its components. The paper concludes with a forward-looking analysis of the potential applications of these compounds in disease treatment, envisioning their role in the future of medical and pharmaceutical advancements.

Kidney disease is a common health problem worldwide. Acute or chronic injuries may interfere with kidney functions, eventually resulting in irreversible kidney damage. A number of recent studies have shown that the plant-derived natural products have an extensive potential for renal protection. ⋯ In addition, TQ exhibited significant pharmacological effects on renal cell carcinoma, renal fibrosis, and urinary calculi. The essential mechanisms involve scavenging ROS and increasing anti-oxidant activity, decreasing inflammatory mediators, inducing apoptosis, and inhibiting migration and invasion. The purpose of this review is to conclude the pharmacological effects and the potential mechanisms of TQ in renal protection, shedding new light on the exploration of medicinal phyto-protective agents targeting kidneys.

Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer. Conventional treatment options for TNBC often have limited efficacy and significant side effects. In recent years, traditional Chinese medicine (TCM) has shown promising results in the treatment of TNBC. ⋯ The method of strengthening the body's resistance emphasizes enhancing the body's original Qi to fight against pathogenic factors; the method of dispelling phlegm seeks to eliminate phlegm stagnation and alleviate the burden on affected organs; the method of removing cancer toxins focuses on detoxification and detumescence to remove the toxic elements associated with TNBC. Although these methods treat TNBC from different etiologies, they have achieved good therapeutic effects and represent an important academic approach: That is, to cure the disease with a comprehensive view of the body and restore the balance of Yin and Yang. This knowledge lays a foundation for the future development and reasonable application of TCM in the clinic.

Ginseng-containing Shentao Ruangan granules (STR) have been a well-known Chinese medicine prescription for the treatment of hepatocellular carcinoma (HCC) in China for decades. This study aimed to establish an in silico experimental framework to decipher the underlying mechanism of STR in the treatment of HCC. Microarray analysis, network pharmacology, RNA-sequencing (RNA-seq), bioinformatics analysis, and in vivo and in vitro experiments were used as integrated approaches to uncover the effects and mechanisms of action of STR. The introduction of STR significantly suppresses the proliferation and metastasis of HepG2 and Huh7 cells. STR treatment notably suppressed the growth of transplanted Huh7 tumors. ⋯ By employing a systems biology approach, 21 common genes were identified across RNA-seq data, TCGA-HCC dataset, and network pharmacology analysis. Finally, of these genes nine were found to be associated with both OS and PFS in patients with HCC within the TCGA cohort. Validation of candidate genes by qPCR and WB identified a significant downregulation in the expression of pGSK3[Formula: see text] and RELA protein with increasing concentrations of STR. These results elucidated the mechanism by which STR inhibits tumor growth and EMT of HCC may be related to the GSK3[Formula: see text]/RELA pathway.

Myocardial ischemia/reperfusion (I/R) injury is the leading cause of death worldwide. Ginsenoside Rd (GRd) has cardioprotective properties but its efficacy and mechanism of action in myocardial I/R injury have not been clarified. This study investigated GRd as a potent therapeutic agent for myocardial I/R injury. ⋯ GRd also increased PI3K and Akt phosphorylation, suggesting activation of the PI3K/Akt pathway, whereas LY294002, a PI3K inhibitor, blocked the GRd-induced inhibition of OGD/R-induced apoptosis and inflammation in H9c2 cells. The therapeutic effect of GRd in vivo and in vitro against myocardial I/R injury was primarily dependent on PI3K/Akt pathway activation to inhibit inflammation and cardiomyocyte apoptosis. This study provides new evidence for the use of GRd as a cardiovascular drug.
