The title compound, CHClN, was synthesized by the cyclization of 1-(4,6-di-methyl-pyrimidin-2-yl)-4-phenyl-thio-semicarbazide in the presence of Ni(NO). The mol-ecular structure of the compound is essentially planar. In the crystal, mol-ecules form dimers pairs of N-H⋯N hydrogen bonds between the H atom of the exocyclic amino group and the N atom at the 4-position of the triazole ring. The resulting dimers are packed into layers which are connected by π-stacking inter-actions between the aromatic systems of the pyrimidine and benzene nuclei, and between the triazole cores.

This study presents an eco-friendly, cost-effective approach for synthesizing highly efficient nanocatalysts with the help of organic waste. Iron nanoparticles (INPs) were synthesized from aqueous extracts of potato, potato peel, and potato leaf and were evaluated for their photocatalytic efficiency for the degradation of methylene blue dye. X-ray Diffraction (XRD) confirmed FeO nanoparticles cubic crystal structure with the smallest crystallite size (9.

We describe a structural and functional study of the G protein-coupled apelin receptor, which binds two endogenous peptide ligands, apelin and Elabela/Toddler (ELA), to regulate cardiovascular development and function. Characterisation of naturally occurring apelin receptor variants from the UK Genomics England 100,000 Genomes Project, and AlphaFold2 modelling, identifies T89 as important in the ELA binding site, and R168 as forming extensive interactions with the C-termini of both peptides. Base editing to introduce an R/H168 variant into human stem cell-derived cardiomyocytes demonstrates that this residue is critical for receptor binding and function.

Alantolactone and isoalantolactone are two isomeric sesquiterpene lactones that were isolated from Innula recemosa. Here, we are used for the semisynthesis of novel isoxazolidine hybrids of alantolactone and isoalantolactone through a two-step process: nitrone synthesis followed by nitrone 1,3-dipolar cycloaddition. The formation of the cycloadduct was well characterized via modern spectroscopic techniques such as HRMS, H NMR, C NMR, DEPT-90, DEPT-135, and 2D NMR.

The P2-NaMnO cathode material has long been constrained by phase transitions induced by the Jahn-Teller (J-T) effect during charge-discharge cycles, leading to suboptimal electrochemical performance. In this study, we employed a liquid phase co-precipitation method to incorporate Ti during the precursor MnO synthesis, followed by calcination to obtain NaTiMnO materials. We investigated the effects of Ti doping on the structure, morphology, Mn concentration, and Na diffusion coefficients of NaTiMnO.

Six new sesquiterpenes, including four eremophilane derivatives fureremophilanes A-D (-) and two acorane analogues furacoranes A and B ( and ), were characterized from the culture extract of the cold-seep derived fungus CS-280 co-cultured with autoclaved QDIO-4. All the six compounds were highly oxygenated especially and with infrequent epoxyethane and tetrahydrofuran ring systems. The structures of - were established on the basis of detailed interpretation of 1D and 2D NMR and MS data.
