Article Abstract

Ultraviolet-visible (UV-vis) spectroscopy represents one of the most popular analytical techniques in chemical research labs. A variety of vendors provide instruments that are suited for the analysis of liquid samples at moderate concentrations. However, to accommodate more specialized experiments, expensive accessories are required and often do not fit the specific needs of experimental scientists. In this work, we present a generalized adapter that can be 3D printed and used with existing spectrometers to enable a wide array of experiments to be performed. In the case of liquid samples, we provide a method for dramatically reducing the price of a quartz cuvette with minimal impact on performance. Through simple modification of the design, cuvettes with various path lengths can be prepared. Additionally, we illustrate the ability to turn any sample container into a working cuvette to simplify experimental protocols, prevent contamination risks, and further reduce costs. This strategy also enables gaseous and solid samples to be evaluated easily and reproducibly. Furthermore, we demonstrate how this concept can be extended to interface additional instrumentation with a commercial UV-vis spectrometer. All of the digital designs are provided under a creative commons license to enable other researchers to modify and adapt the designs for their unique experimental requirements.

In this work, magnetic molecularly imprinted polymer (MMIP) capable of selectively recognizing and adsorbing cordycepin was prepared. The MMIP was prepared using cordycepin as the template molecule, methacrylic acid and acrylamide as the functional monomer and ethylene glycol dimethacrylate as the crosslinker. The MMIP was analyzed using various techniques including transmission electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, vibrating sample magnetometer and x-ray diffraction.

An analytical method for identifying the chemical constituents in the Chinese herbal combination Jiuwei decoction was established using capillary electrophoresis coupled with quadrupole time-of-flight mass spectrometry. Nine herbs were extracted with a 60:40 (v/v) ethanol/water solution to prepare the Jiuwei decoction. Electrophoretic separation was carried out using a 50 µm i.

This study introduces a green approach to sample preparation by applying natural deep eutectic solvents (NADES) to determine phthalates in carbonated soft drinks using high-performance liquid chromatography with diode array detector (HPLC-DAD). The method employs hollow fiber-microporous membrane liquid-liquid microextraction combined with a 96-well plate system, utilizing fatty-acid-based DES in the pores of the membranes. This methodology substantially reduces the use of organic solvents, and its efficiency is comparable to or better than conventional methods.

Pharmacokinetic Interaction between Imatinib and Tacrolimus in Rats.

Curr Drug Metab

December 2024

Department of Pharmacy, the Fourth Hospital of Hebei Medical University, Hebei Key Laboratory of Clinical Pharmacy, Shijiazhuang, China.

Objective: Tacrolimus, a calcineurin inhibitor (CNI), is the first-line treatment for chronic myeloid leukemia (CML) and advanced gastrointestinal stromal tumors (GIST). Imatinib and tacrolimus are both substrates of the hepatic enzymes CYP3A4/5 and efflux transporter P-gp, so drug-drug interactions may occur during their co-administration treatment. Therefore, this study aimed to evaluate the pharmacokinetic interaction between imatinib and tacrolimus in rats.
