The asymmetric unit of the title compound, C(15)H(15)ClN(4)O(6)S, contains two independent mol-ecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 75.21 (3) and 86.00 (3)°. Intra-molecular N-H⋯N and C-H⋯O hydrogen bonds result in the formation of two five- and two six-membered rings. The six-membered rings have flattened-boat conformations, while the five-membered rings adopt envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.

Freezing extends the shelf life of foods but often leads to structural damage due to ice crystal formation, negatively impacting quality attributes. Oscillating magnetic field (OMF)-assisted supercooling has emerged as a potential technique to overcome these limitations by inhibiting ice nucleation and maintaining foods in a supercooled state. Despite its potential, the effectiveness and underlying mechanisms of OMF-assisted supercooling remain subjects of debate.

After more than 15 years of decline, the Malaria epidemy has increased again since 2017, reinforcing the need to identify drug candidates active on new targets involved in at least two biological stages of the Plasmodium life cycle. The SUB1 protease, which is essential for parasite egress in both hepatic and blood stages, would meet these criteria. We previously reported the structure-activity relationship analysis of α-ketoamide-containing inhibitors encompassing positions P4-P2'.

Succinate dehydrogenase (SDH) has been identified as one of the ideal targets for the development of novel nematicides. However, the resistance of nematodes to fluopyram, one of the commercialized SDH inhibitors, is becoming a growing concern. Since expanding the structural diversity around an active scaffold is a useful strategy for drug development, herein a series of fluopyram analogues with a broad, biologically relevant indole moiety were synthesized and evaluated for nematicidal activity against C.

The Orange Carotenoid Protein (OCP) is a unique water-soluble photoactive protein that plays a critical role in regulating the balance between light harvesting and photoprotective responses in cyanobacteria. The challenge in understanding OCP´s photoactivation mechanism stems from the heterogeneity of the initial configurations of its embedded ketocarotenoid, which in the dark-adapted state can form up to two hydrogen bonds to critical amino acids in the protein's C-terminal domain, and the extremely low quantum yield of primary photoproduct formation. While a series of experiments involving point mutations within these contacts helped us to identify these challenges, they did not resolve them.

Piperazine-based compounds have garnered significant attention due to their notable biological and pharmacological activities, making them essential in fine chemical and pharmaceutical applications. In this study, we managed to synthesize a novel hybrid bis-cyanoacrylamide bearing the piperazine core via phenoxymethyl linker and incorporating sulphamethoxazole moiety. The novel compound was fully characterized using different spectral data including 1H-NMR, C-NMR, and FTIR spectroscopy.
