Development of a Simple and Rapid HPLC-UV Method for Simultaneous Determination of Ciprofloxacin Hydrochloride and Oxytetracycline Hydrochloride in Aqueous Matrix.

Soon Wan Chi WC, Bin Abdullah Ahmad Zuhairi AZ, Mohd Din Azam Taufik AT

Reliable and effective methods capable of simultaneously determining ciprofloxacin hydrochloride (CIP) and oxytetracycline hydrochloride (OTC) can be useful when concentrations fall within the validated working range. This study aimed to develop and validate a simple and rapid reversed-phase high-performance liquid chromatography with ultraviolet detection (RP-HPLC-UV) method for simultaneous determination of CIP and OTC in aqueous matrices. The separation was performed using an Agilent InfinityLab Poroshell 120 EC-C18 column (150 × 4.6 mm, 4 μm) with a mobile phase consisting of 0.1% formic acid and acetonitrile at a flow rate of 1.0 mL/min. The method was validated for linearity, precision, selectivity, recovery, sensitivity, robustness and system suitability. Matrix performance was assessed using fortified lake-water samples. Linearity over the concentration range of 10-25 mg/L, with R² values of 0.9947 for OTC and 0.9923 for CIP was achieved. The LOD values were 1.40 mg/L for OTC and 1.69 mg/L for CIP, while the corresponding LOQ values were 4.24 and 5.11 mg/L, respectively. Peak-area RSDs were below 1% in both intraday and interday precision studies. Recoveries in fortified lake water ranged from 91.12-109.13% for OTC and 82.88-107.72% for CIP and from 95.84-104.91% and 89.56-112.88%, respectively, in interday analysis. Robustness testing showed that satisfactory chromatographic separation was maintained under the investigated variations in flow rate, column temperature, and detection wavelength. The HPLC-UV approach was applicable for the simultaneous determination of CIP and OTC in aqueous samples containing relatively elevated concentrations of the target antibiotics. The method is not intended for direct trace-level determination in typical environmental waters without an appropriate preconcentration step. A simple RP-HPLC-UV method was developed for the simultaneous determination of CIP and OTC. The method is applicable to aqueous samples containing relatively elevated antibiotic concentrations.

Co-delivery of siPD-L1 and Tat-HSPB1 by G5PBA Enhances the Efficacy of Antitumor Therapy in Clear Cell Renal Cell Carcinoma.

Xiong Kui K, Xia Lili L, Zhang Lin L, Li Weiyuan W et al.

Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cell carcinoma and remains challenging to treat at advanced stages due to immune evasion and inefficient intracellular delivery of therapeutic agents. In this study, we synthesized a modified generation 5 (G5) poly(amidoamine) dendrimer (G5PBA) to co-deliver small-interfering RNA targeting programmed death-ligand 1 (siPD-L1) and the antitumor peptide Tat-HSPB1, forming the G5PBA/siPD-L1/Tat-HSPB1 nanocomplex. The agarose gel retardation assay demonstrated that G5PBA efficiently condensed siPD-L1. Furthermore, the peptide encapsulation efficiency and loading capacity were measured, confirming the loading of Tat-HSPB1 into G5PBA/siPD-L1. Flow cytometry showed that G5PBA enhanced the cellular uptake of siPD-L1, while confocal microscopy demonstrated that G5PBA promoted lysosomal escape in Caki-1 cells. Western blot analysis further confirmed that G5PBA effectively reduced the PD-L1 protein expression. In cellular experiments, CCK-8, EdU, and wound-healing assays demonstrated that G5PBA/siPD-L1/Tat-HSPB1 inhibited the viability and migration of ccRCC cells. G5PBA/siPD-L1/Tat-HSPB1 suppressed tumor growth, downregulated PD-L1 expression, enhanced CD4+ and CD8+ T-cell infiltration, and elevated serum levels of IL-2, IL-6, TNF-α, and IFN-γ in mice. Major organs exhibited no obvious histopathological abnormalities upon H&E staining. Serum ALT, AST, and BUN levels showed no significant changes compared with the PBS group, suggesting the preliminary safety profile of G5PBA/siPD-L1/Tat-HSPB1. Collectively, the nanocomplex achieved efficient peptide/siPD-L1 co-delivery and demonstrated significant antitumor activity. This system thus provides a promising strategy and experimental basis for local administration of ccRCC.

Doping Control Analysis of Darbepoetin Alfa Biosimilars in Human Urine, Serum, Plasma, and Dried Blood Spots.

Akiyama Kentaro K, Sakurai Hikaru H, Sato Mitsuhiko M, Momobayashi Atsushi A et al.

Following the patent expiration of the originator darbepoetin alfa, three biosimilar products have been marketed in Japan; however, their detectability by current anti-doping methods has not yet been verified. The present study assessed whether these biosimilars can be detected in human urine, serum, plasma, and dried blood spots (DBS) using the established initial testing procedure and confirmation analysis for erythropoietin-receptor agonists. The originator product and three biosimilars (5 μg, i.v.) were administered to healthy male volunteers. Samples collected up to 72 h postdose were subjected to immunopurification followed by sodium N-lauroyl sarcosinate polyacrylamide-gel electrophoresis (SAR-PAGE) as the initial testing procedure. Confirmation was performed by SAR-PAGE with double blotting for serum and plasma. DBS and urine samples were confirmed by SAR-PAGE using an alternative antibody, and urine samples were further examined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). SAR-PAGE analysis of the pharmaceutical preparations revealed product-specific electrophoretic profiles: two biosimilars migrated slightly above one originator product as diffused smears, whereas the third produced a sharp band comparable to that of another originator product. Similar profiles were observed in postdose samples from all biological matrices, and all biosimilars remained detectable in urine, serum, plasma, and DBS for at least 72 h. Although some biosimilars showed distinct SAR-PAGE banding patterns, product attribution remained limited. LC-MS/MS confirmed administered darbepoetin alfa in the 24 h urine samples but did not detect analyte in lower concentration samples, indicating that its performance was concentration-dependent. Accordingly, SAR-PAGE should incorporate reference standards beyond the originator product, particularly those with different band morphologies.

Anion-Regulated Phase Separation Constructs Mechanically Tunable Ion Gels for Strain Sensing.

Gao Jie J, Guo Song S, Ji Zhe Z, Cao Mo M et al.

Although ion gels are promising for flexible sensing, simultaneously achieving high mechanical strength, stretchability, ionic conductivity, and interfacial adhesion remains challenging. Here, we report the preparation of ion gels with tunable mechanical properties using two ionic liquids (ILs) with different compatibilities with poly(acrylic acid) (PAA) via a one-pot ultraviolet (UV)-initiated polymerization. Adjusting the mixing ratio of the two ILs can regulate the phase separation of the gel and promote the formation of a bicontinuous phase. The optimized ion gel exhibits a tensile strength of 11 MPa, high elongation at break (363%), excellent ionic conductivity (1.4 × 10- 2 mS cm- 1), and robust interfacial adhesion. Ion gel-based strain sensors exhibit sensitive, reproducible resistance responses over a wide strain range and enable repeatable monitoring of human joint motions and daily activities. This work establishes a simple anion-regulated phase separation strategy for engineering high-performance ion gels for wearable sensing.

A One-Stone-Two-Birds Strategy to Develop P-Por COF/PDES Composite Gels for Photothermal/Photodynamic Antibacterial Activity and Wearable Strain Sensing.

Ma Zheng Z, Wang Linlin L, Fan Ziyang Z, Yang Wenjie W et al.

Flexible wearable electronics face growing bacterial infection risks from prolonged skin contact, creating an urgent demand for flexible materials integrating efficient sensing and antibacterial functions. Herein, a novel phosphorus-containing porphyrin covalent organic framework (P-Por COF) was synthesized via a solvothermal Schiff-base reaction, and incorporated into a polymerizable deep eutectic solvent to fabricate P-Por COF/PDES composite gels through in-situ UV polymerization. The resulting gel exhibited enhanced photothermal performance, improved mechanical properties, and excellent near-infrared (NIR) triggered antibacterial activity. Under 730 nm NIR light irradiation, the P-Por COF/PDES composite gel could reach 76 °C with 4 min, while showing excellent stability of photothermal cycle. Based on the synergistic effect of photodynamic production of singlet oxygen and photothermal effect, the P-Por COF/PDES composite gel resulted in a high bactericidal rate of nearly 100% against both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The P-Por COF/PDES composite gel delivered a fracture strain up to 2435.82% and 2.6-fold higher toughness than pure PDES, along with stable, sensitive and self-healable strain sensing for human motion monitoring. Overall, this work provides a simple and effective strategy for developing antibacterial materials and multifunctional gels with integrated therapeutic and sensing capabilities.
