Microenvironment-responsive, multimodulated herbal polysaccharide hydrogel for diabetic foot ulcer healing.

Diabetic ulcers (DUs) usually suffer from severe infections, persistent inflammation, and excessive oxidative stress during the healing process, which led to the microenvironmental alternation and severely impede DU healing, resulting in a delayed wound healing. Therefore, it is particularly important to develop a medical dressing that can address these problems simultaneously. To this end, self-healing composite hydrogels were prepared in this study utilizing Bletilla striata polysaccharide (BSP) and Berberine (BER) with borax via borate ester bond.

Natural Product-Inspired Discovery of Naphthoquinone-Furo-Piperidine Derivatives as Novel STAT3 Inhibitors for the Treatment of Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, and STAT3 has emerged as an effective drug target for TNBC treatment. Herein, we employed a scaffold-hopping strategy of natural products to develop a series of naphthoquinone-furopiperidine derivatives as novel STAT3 inhibitors. The assay showed that compound possessed higher antiproliferative activity than Cryptotanshinone and Napabucasin against TNBC cell lines, along with lower toxicity and potent antitumor activity in a TNBC xenograft model.

Total flavonoids from the aerial parts of Tetrastigma hemsleyanum prevent LPS-induced ALI by modulating the TLR4/NF-κB pathway in mice.

Background: The traditional Chinese medicine Tetrastigma Hemsleyanum (TH) is employed in treating respiratory diseases; however, the aerial parts by which its total flavonoids alleviate acute lung injury (ALI) are still unknown. This study investigated the protective effect and mechanism of Tetrastigma Hemsleyanum flavonoids (THF) in lipopolysaccharide (LPS)-induced ALI in mice.

Methods: Firstly, the total flavonoids from the above-ground part of TH were extracted.

Molecular mechanisms of cisplatin resistance in ovarian cancer.

Ovarian cancer is one of the most common malignant tumors of the female reproductive system. The majority of patients with advanced ovarian cancer are mainly treated with cisplatin-based chemotherapy. As the most widely used first-line anti-neoplastic drug, cisplatin produces therapeutic effects through multiple mechanisms.

A novel sesquiterpene lactone fraction from Eupatorium chinense L. suppresses hepatocellular carcinoma growth by triggering ferritinophagy and mitochondrial damage.

Background: Hepatocellular carcinoma (HCC) is an aggressive tumor with limited treatment options, and it is the third leading cause of cancer-related deaths. Hence, novel therapeutic strategies are required to treat HCC. Eupatorium chinense L.

Cardioprotective effect of crude polysaccharide fermented by Trametes Sanguinea Lyoyd on doxorubicin-induced myocardial injury mice.

Doxorubicin (DOX) is a broad-spectrum anti-tumor drug, but its clinical application is greatly limited because of the cardiotoxicity. Thus, exploration of effective therapies against DOX-induced cardiotoxicity is necessary. The aim of this study is to investigate the effects and possible mechanisms of Trametes Sanguinea Lyoyd fermented crude polysaccharide (TSLFACP) against DOX-induced cardiotoxicity.
