The electronic effect of -butyl groups on intramolecular through-bond interactions between redox units in tetrathiafulvalene-tetraazapyrene (TAP) triads is investigated. The insertion of -butyl groups raises the TAP-localised LUMO level by 0.21 eV, in fairly good agreement with 0.17 eV determined by DFT calculations.

Butyl phenyl--phosphinate that is not available commercially was prepared from phenyl--phosphinic acid by three methods: by alkylating esterification (i), by microwave-assisted direct esterification (ii), and unexpectedly, by thermal esterification (iii). Considering the green aspects, selectivity and scalability, the thermal variation seemed to be optimal. However, there was need for prolonged heating.

Over-accumulation of reactive oxygen species (ROS) causes hepatocyte dysfunction and apoptosis that might lead to the progression of liver damage. Sirtuin-3 (SIRT3), the main NAD+-dependent deacetylase located in mitochondria, has a critical role in regulation of mitochondrial function and ROS production as well as in the mitochondrial antioxidant mechanism. This study explores the roles of astragaloside IV (AST-IV) and formononetin (FMR) in connection with SIRT3 for potential antioxidative effects.

Ionic liquids were used as low temperature solvents for the synthesis of new lanthanide and transuranic-element (TRU) borate cluster structures. Ionothermal synthesis with the ionic liquid [BMIm]Cl (1-butyl-3-methylimidazolium chloride) yielded the La, Nd, and Am containing phases LaBOCl, NdBOCl, and AmBOCl. The structures of the La, Nd, and Am borate clusters were determined by single crystal X-ray diffraction (SCXRD) and found to be cubic, in the chiral space group 23.

The endosomal escape of lipid nanoparticles (LNPs) is crucial for efficient mRNA-based therapeutics. Here, we present a cationic polymeric micelle (cPM) as a safe and potent co-delivery system with enhanced endosomal escape capabilities. We synthesized a cationic and ampholytic di-block copolymer, poly (poly (ethylene glycol) methacrylate--hexyl methacrylate)--poly(butyl methacrylate--dimethylaminoethyl methacrylate--propyl acrylate) (p(PEGMA--HMA)--p(BMA--DMAEMA--PAA)), via reversible addition-fragmentation chain transfer polymerization.

Endocrine-disrupting chemicals (EDCs), including phthalates, have been implicated in the development of non-alcoholic fatty liver disease (NAFLD) and hepatic fibrosis. This study investigates the age-dependent effects of butyl benzyl phthalate (BBP) exposure on lipid metabolism in the livers of young and aged mice. Young (2-month-old) and aged (20-month-old) male C57BL/6 mice were exposed to BBP through drinking water at a dose of 169 μg/kg/day for 6 and 4 months, respectively.
