The asymmetric unit of the title complex, [Sn(4)(C(4)H(9))(8)(C(11)H(14)NO(2))(4)O(2)], consists of two crystallographically independent half-mol-ecules. The other halves are generated by crystallographic inversion centers. In each tetra-nuclear mol-ecule, both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. Weak intra-molecular C-H⋯O hydrogen bonds stabilize the mol-ecular structures. In one mol-ecule, two of the butyl groups and the bridging benzoate anion are each disordered over two positions.

Alkyl nitrites are a class of inhalant, commonly known as 'poppers'. Although having medical uses, some other effects include a 'rush', 'high', 'euphoria', or feeling of excitement. This has led to their recreational use, in different scenarios, since the mid-1960s.

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.
