The title compound, C(17)H(18)N(2)OS, adopts a trans-cis geometry of the thio-urea group which is stabilized by intra-molecular hydrogen bonds between the O atom of the carbonyl group and the H atom of the thio-amide group. A C-H⋯S intramolecular hydrogen bond is also present. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯S hydrogen bonds to form centrosymmetric dimers.

The degree of sulfonation (DS) is a key property of sulfonated polymers, as it significantly influences their swelling behaviour, conductivity and mechanical properties. Accurately determining the DS is essential for optimizing these materials for various applications. In this work, the DS of sulfonated poly (ether ether ketone) (SPEEK) was evaluated using a combination of analytical techniques, including titration, back titration, Fourier Transform Infrared (FTIR), Ultra-Violet (UV) and proton nuclear magnetic resonance (H NMR) spectroscopies, Thermogravimetric analysis (TGA), Rutherford backscattering (RBS) and particle induced X-ray emission (PIXE) analysis.

Supramolecular oleogels, in which low-molecular weight oleogelators self-assemble into various nanostructures through non-covalent interactions, have witnessed increasing research activity in various fields of science, including food, cosmetics or remediation of marine oil spills. Herein, we report a simple scalable and environmentally friendly carbohydrate-based oleogelator, namely, the sodium salt of ,'-dimethyl β- glucosyl barbiturate (GlcBMe) that self-assembles through sonication to induce the gelation of polar organic solvent and later of non-polar vegetable oils by cationic exchange with quaternary ammonium surfactants. Water-soluble GlcBMe was capable of forming self-assembled fibrillar network bridging insoluble particles in the oil by sonication in the presence of a small amount of water.

Chronic myeloid leukaemia (CML) is primarily treated using imatinib mesylate, a tyrosine kinase inhibitor (TKI) targeting the BCR::ABL1 oncoprotein. However, the development of drug resistance and adverse side effects necessitate the exploration of alternative therapeutic agents. This study presents the synthesis and characterization of a novel imatinib analogue, 3-chloro--(2-methyl-5-((4-(pyridin-2-yl)pyrimidin-2-yl)amino)phenyl)benzamide (PAPP1).

Amorphous solid dispersion (ASD) is one of the most studied strategies for improving the dissolution performance of poorly water-soluble drugs, but ASDs often have low drug loadings, thereby necessitating larger dosage sizes. This study intended to create Soluplus® (SOL)-based microparticle ASDs with high drug loading (up to 60 w/w%) and long-term stability (at least 16 months) using electrospraying to enhance the dissolution of poorly water-soluble celecoxib (CEL). X-ray diffraction (XRD) and differential scanning calorimetry (DSC) analyses showed that the electrosprayed SOL-CEL microparticles were amorphous, and Fourier transform infrared spectroscopy (FTIR) data indicated the presence of hydrogen bonding between SOL and CEL in the microparticles, which helped stabilize the ASDs.
