Summary: 5-Hydroxymethyl-2-furaldehyde (5-HMF) is an aldehyde compound generated from the dehydration of glucose and fructose. It is found in drugs, foods, cosmetics, and traditional Chinese medicine preparations with high sugar content. A comprehensive study was conducted to identify and characterize the degradation products (DPs) of 5-HMF under different degradation conditions. Five DPs were identified, including two novel DPs. Major DPs were isolated and characterized, and the degradation pathways and mechanisms were explained. In silico toxicity and metabolism evaluations suggested potential hepatotoxicity, mutagenicity, chromosome damage, and skin sensitization for both 5-HMF and its DPs. This research has implications for quality control and storage conditions of 5-HMF.

Summary: The degradation profile of ponatinib was established using various stress conditions and in-silico degradation pattern was outlined using Zeneth software. Five degradation impurities were formed and an HPLC method was developed to separate them. The structures of the impurities were proposed by high resolution mass spectrometry and their toxicity and mutagenicity profiles were predicted in-silico. This study provides meaningful insights into the chemical stability of ponatinib, which is valuable in its drug development lifecycle.

Summary: This article studied the degradation of Roxadustat and identified nine degradation products through forced degradation studies. Among them, DP-4 was the major degradation impurity, generated under alkaline hydrolysis, neutral hydrolysis, and photolysis conditions. Toxicity studies revealed that DP-4 showed carcinogenicity, and molecular docking confirmed the potential interaction of DPs with proteins responsible for toxicity.

Summary: Bortezomib (BTZ) is a potent reversible inhibitor of proteasome used in the treatment of multiple myeloma. Studies on its degradation under various conditions identified 16 degradation products, with some showing toxicity in vitro cell toxicity tests. Further in silico studies suggested potential hepatotoxicity and genotoxicity of BTZ and its degradation products.

Summary: Dabrafenib (Tafinlar) is used for the treatment of BRAF V600 mutation positive unresectable or metastatic melanoma. Forced degradation study of dabrafenib was conducted to identify and characterize its major degradation products under various stress conditions. Dabrafenib showed sensitivity to oxidative degradation and photolytic degradation, but remained stable in acidic, alkaline, neutral, and thermal degradation environments. The study identified five major degradation products under oxidative stress and three major degradation products under photolytic degradation, further characterized by HRMS/MS/TOF technique. The degradation pathway of dabrafenib was established with fragmentation pathways of degradation products explained.

Summary: Dexamethasone (DEX), a steroid hormone with potential endocrine disrupting properties, needs efficient elimination during water treatment for human and aquatic health protection. Different oxidative processes showed varied efficiency in DEX removal, with mainly observed chemical transformations including alcohol oxidation, ozonolysis, and decarboxylation. Evaluation of DEX and its derivatives' toxicities revealed that certain degradation products may be toxic to humans due to stable interaction with the glucocorticoid receptor.

Summary: Taxifolin, isolated from the seeds of Mimusops balata, was found to be extremely unstable under alkaline hydrolysis and its thermal degradation was increased by humidity. However, it displayed stability in terms of photosensitivity. Alkaline degradation products were identified as dimers of taxifolin. These findings contribute to the development of stability-indicating methods and appropriate drug release systems to preserve its stability and enhance bioavailability.

Summary: A forced degradation study was conducted on acalabrutinib (ACB) to identify and characterize all possible major degradation products formed under different stress conditions. The degradation products were separated and isolated using HPLC and characterized using LC-ESI-HRMS/MS and NMR. Seven major degradants were formed under alkaline, acidic, basic, and hydrogen peroxide stress conditions. ACB remained stable under neutral pH, thermal, and UV radiation conditions. Interestingly, pseudo geometrical isomeric degradation products were observed.

Summary: The study investigated the degradation kinetics and mechanisms of spiramycin under thermally activated peroxydisulfate oxidation process in aqueous solution. It was found that the degradation rate of spiramycin could be expressed by a kinetic rate equation. Sulfate radical and hydroxyl radical were identified as the dominant reactive species, with the former's contribution decreasing with an increase in pH value. Additionally, the presence of humic acid and inorganic anions negatively impacted the degradation of spiramycin.

Summary: Forced degradation tests are used to evaluate the stability of APIs and their formulations by subjecting them to extreme conditions to identify degradation products. This study proposes the use of DoE approach in forced degradation of ABZ, revealing that ABZ oxidation is the main degradation route influenced by temperature. LC-IT-MSn identified three known degradation products and a new derivative of ABZ molecule, which was isolated and characterized by UPLC-QToF-MS and NMR analyses.

Summary: This study evaluated the antileishmanial activity of V. brasiliana leaves using in vitro and in silico approaches. The results showed that V. brasiliana had inhibitory activity against Leishmania and low cytotoxicity. Therefore, V. brasiliana and its metabolites may serve as potential lead compounds for leishmaniasis treatment.

Summary: The sonochemical degradation of acesulfame, a widely used artificial sweetener, was studied. It was found that complete degradation of acesulfame was achieved within 120 min under conditions suitable for high production of free radicals. The coupling of sonochemical degradation with sodium persulfate enhanced the rate of acesulfame oxidation.
