The SwissTargetPrediction was employed to predict the potential drug targets of the active component of Si-Miao-Yong-An decoction (SMYAD). The therapeutic targets for HF were searched in the Genecard database, and Cytoscape3.9.1 software was used to construct the "drug-component-target-disease network" diagram. In addition, the String platform was used to construct Protein-Protein Interaction (PPI) network, and the DAVID database was used for GO and KEGG analysis. AutoDockTools-1.5.6 software was used for molecular docking verification. Network pharmacology studies have shown that AKT 1, ALB, and CASP 3 are the key targets of action of SMYAD against heart failure. The active compounds are quercetin and kaempferol.

The flavonoid compound chinonin is one of the main active components of Rhizoma anemarrhena with multiple activities, including anti-inflammatory and antioxidant properties, protection of mitochondrial function and regulation of immunity. In this paper, we reviewed recent research progress on the protective effect of chinonin on brain injury in neurological diseases. “Chinonin” OR “Mangiferin” AND “Nervous system diseases” OR “Neuroprotection” was used as the terms for search in PumMed. After discarding duplicated and irrelevant articles, a total of 23 articles relevant to chinonin published between 2012 and 2023 were identified in our study.

Dendroochreatene (1), a new phenanthrene derivative with a spirolactone ring, was isolated from the whole Dendrobium ochreatum plant together with 11 known compounds (2–12). The structure of the new compound was elucidated spectroscopically and phenolic compounds were firstly reported from D. ochreatum. Moscatilin (4), major compound isolated from D. ochreatum, was found to be cytotoxic toward H460 lung-cancer cells, with an IC50 value of 147.3 ± 0.9 µM, while loddigesiinol C (7), C-α-methoxy derivative was inactive.

Breast cancer is the most common malignant tumor and a major cause of mortality among women worldwide. Atramacronoid A (AM-A) is a unique natural sesquiterpene lactone isolated from the rhizome of Atractylodes macrocephala Koidz (known as Baizhu in Chinese). Our study demonstrated that AM-A triggers a specific form of cell death resembling PANoptosis-like cell death. Further analysis indicated that AM-A-induced PANoptosis-like cell death is associated with the CASP-3/PARP-GSDMD-MLKL pathways, which are mediated by mitochondrial dysfunction. These results suggest the potential of AM-A as a lead compound and offer insights for the development of therapeutic agents for breast cancer from natural products.
乳腺癌是最常见的恶性肿瘤，也是全球妇女死亡的主要原因。Atramacronoid A (AM-A) 是一种独特的天然倍半萜内酯，从白术根茎中分离出来。我们的研究表明，AM-A 能引发一种特殊形式的细胞死亡，类似于 PANoptosis 样细胞死亡。进一步的分析表明，AM-A诱导的PAN凋亡样细胞死亡与线粒体功能障碍介导的CASP-3/PARP-GSDMD-MLKL通路有关。这些结果表明，AM-A 有可能成为一种先导化合物，并为从天然产品中开发乳腺癌治疗药物提供了启示。

Their structures were determined using spectroscopic analysis. All compounds were evaluated for their DPPH radical scavenging activity.

This study examined the impact of Semen raphani on the absorption of ginsenosides from Panax ginseng C.A. Meyer (ginseng) using a Caco-2 cell model and Ultra-High-Performance Liquid Chromatography-Electrospray Ionization-Tandem Mass Spectrometry (UPLC-ESI-MS). Six primary ginsenosides (Rg1, Re, Rb1, Rb2, Rc, Rd) were quantified. Results showed that Semen Raphani increased the efflux rate of ginsenosides, particularly at higher concentrations, suggesting it inhibits their absorption. The research elucidates the intestinal absorption process of ginsenosides and the antagonistic mechanism of Semen Raphani against ginseng.

Lupalbigenin (1) is an antibacterial isoflavone isolated from Maclura cochinchinensis (Lour.) Corner (Moraceae). In this study, we achieved the first gram-scale synthesis of lupalbigenin (1) from commercially available genistein (2), with a yield of 47.7%. The key step was a Claisen rearrangement that simultaneously installed two prenyl groups at the C-6 and C-11 positions of lupalbigenin (1). Antimicrobial activity assays revealed that lupalbigenin (1) exhibited rapid bactericidal activity, inhibited α-hemolysin and biofilm formation, and disrupted bacterial cell membranes. These findings suggest that lupalbigenin (1) is a promising candidate for the development of novel antibiotics to combat bacterial infections.

ABATRACTTwo new compounds, namely, isorhamnenin-3-O-neohesperidin-6''-linoleic acid ester (1) and isorhamnenin-3-O-neohesperidin-6''-palmitate (2), along with 17 known compounds, were isolated from Pollen Typhae Carbonisatus (PTC). Their structures were elucidated on the basis of one-dimensional (1D)-, two-dimensional (2D)-nuclear magnetic resonance (NMR), and high-resolution electrospray ionization mass spectrometry (HRESIMS) spectroscopic data analyses. The two new compounds (1 and 2) exhibited a protective effect in a dose-dependent manner and promoted tube generation in the oxygen-glucose deprivation/reoxygenation (OGD/R)-induced human brain microvascular endothelial cells (HBMECs).

Visceral leishmaniasis still remains a leading cause of parasitic deaths, with modern pentavalent antimonials showing limited efficacy and health risks. The methanolic bark extract of the Northeastern Indian plant, Garcinia cowa, demonstrated potent leishmanicidal effects against the parasite Leishmania donovani, demonstrating IC50 values of 20-36 µg/ml, with selective toxicity for parasites over healthy cells. It induced parasite death through elevated oxidative and nitrosative stress elements, reduced arginase activity, nuclear fragmentation, cell cycle arrest, and apoptosis. A GC-MS study and molecular docking identified stigmasterol as a primary component, an antileishmanial compound that inhibits Leishmania donovani parasite efficiently.
