Bioactive Sulfonamides Derived from Amino Acids: Their Synthesis and Pharmacological Activities.

Mini Rev Med Chem

January 2025

Department of Physiology and Pharmacology Vittorio Erspamer, Sapienza University of Rome, 00161, Rome, Italy.

Currently, the synthesis of bioactive sulfonamides using amino acid as a starting reagent has become an area of research interest in organic chemistry. Over the years, an amine-sulfonyl chloride reaction has been adopted as a common step in traditional sulfonamide synthetic methods. However, recent developments have shown amino acids to be better precursors than amines in the synthesis of sulfonamides.

Background Severe acute pancreatitis (SAP) manifests as a critical state marked by acute abdominal symptoms, often associated with intestinal barrier dysfunction, exacerbating SAP retroactively. Ganoderic acid A (GAA) demonstrates anti-inflammatory properties in various inflammatory disorders. Nonetheless, its potential therapeutic impact on SAP and the underlying mechanisms remain unexplored.

Gold nanorods coated with self-assembled silk fibroin for improving their biocompatibility and facilitating targeted photothermal-photodynamic cancer therapy.

Nanoscale

January 2025

Zhejiang Provincial Key Laboratory of Utilization and Innovation of Silkworm and Bee Resources, Institute of Applied Bioresource Research, College of Animal Science, Zhejiang University, Yuhangtang Road 866, Hangzhou, 310058 Zhejiang, P. R. China.

Gold nanorods (AuNRs) have shown great potential as photothermal agents for cancer therapy. However, the biosafety of AuNRs ordinarily synthesized using a cationic ligand assistance procedure has always been a subject of controversy, which limits their application in tumor therapy. In this study, we propose a novel strategy to enhance the biocompatibility of AuNRs by constructing a biological coating derived from silk fibroin (SF) on their surface.

Introduction: The objective of this study was to improve the economic value of the processed by-products of farmed miiuy croaker () by evaluating the nutrient composition and osteogenic activity of its bones. We prepared bone peptides (MMBP) and analyzed their osteogenic potential.

Methods: We assessed the osteogenic activity of MMBP by molecular docking, MC3T3-E1 cell proliferation assay and zebrafish growth model, and evaluated its effect on osteoporosis (OP) using a retinoic acid-induced osteoporosis rat model.

Virtual screening and evaluation of bioactive peptides from as potential HMGCR inhibitors for hyperlipidemia treatment.

Front Nutr

December 2024

Key Laboratory of Cultivation and High-Value Utilization of Marine Organisms in Fujian Province, Fisheries Research Institute of Fujian, Xiamen, China.

Introduction: Hyperlipidemia remains a major disease threatening global public health. The morbidity and mortality associated with cardiovascular diseases have been increasing. The inhibition of 3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR), a key enzyme in the cholesterol synthesis pathway, can effectively reduce cholesterol levels.
