A Novel Label-Free Method for Efficient Detection of Bisphosphonate Drug Dissolution Rates Using Surface-Enhanced Raman Spectroscopy.

We developed a novel method utilizing surface-enhanced Raman spectroscopy (SERS) with calcium ion-modified silver nanoparticles as the enhancing substrate. This approach enables label-free detection of the dissolution rate of bisphosphonates. This technique is fast, sensitive, and highly reproducible, significantly advancing drug quality control.

Structural characterisation and anti-colon cancer activity of an arabinogalactan RSA-1 from Raphani semen.

RSA-1 is a polysaccharide obtained from Raphani semen with a relatively clear structure and anti-colon cancer activity. In this study, high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR) spectroscopy were applied to characterise the complex chain structure of RSA-1. Subsequently, the inhibitory effect on colon cancer growth through apoptosis induction in colon cancer cells was explored.

Identification of in the Potential Treatment of Alzheimer's Disease by Integrating Virtual Screening and In Vitro Validation.

(Gouteng in Chinese, GT) is the main medicine in many traditional recipes in China. It is commonly used to alleviate central nervous system (CNS) disorders, although its mechanism in Alzheimer's disease is still unknown. This study was designed to predict and validate the underlying mechanism in AD treatment, thus illustrating the biological mechanisms of GT in treating AD.

Simultaneous Determination of Five Iridoids of in Rat Plasma Using UHPLC-ESI-MS/MS.

In this study, we developed an ultra-performance liquid chromatography-electrospray tandem quadrupole mass spectrometry (UHPLC-ESI-MS/MS) method to simultaneously determine Picroside-I, Picroside-II, Picroside-III, minecoside, and sweroside in rat plasma. The chromatographic column was an ACQUITY UHPLC BEH Amide Column (2.1 × 100 mm, 1.
