The ability to program molecules to bind to specific sequences of DNA with high fidelity and stability is an important goal of chemical biology. Such molecules can compete with transcription-factor proteins and thus modulate the transcription of genes. They are therefore promising for both elucidating the complex regulation of mammalian gene expression, and developing pharmaceuticals and medical diagnostics targeted to genetic abberations. Writing in Nature Chemistry, Brent Iverson and co-workers have now described the excellent sequence specificity and unusual binding kinetics of a stable DNA–ligand complex, which exhibits a half-life of 16 days.

[extract] This Research Front of the Australian Journal of Chemistry is aligned with the BIOPHYSCHEM2011 meeting, a joint conference of the Australian Society for Biophysics and the Physical Chemistry Division of the RACI, which was held at the University of Wollongong from 3 to 6 December 2011. Just shy of 200 delegates made the journey to the Illawarra as these two societies came together for the first time for a national meeting. The idea for this collaboration sprang from the inaugural Australian Biophysical Chemistry Workshop, coordinated by Dr Ron Clarke (U. Sydney) and Dr Tak Kee (U. Adelaide) in 2010. …

It is an essential ingredient in food production, but poor management means bad news downstream. Understanding the way phosphorus behaves in the environment calls for soil and plant biology, and some new soil chemistry.

There is significant commercial interest in oil extraction from krill because it is rich in omega-3 polyunsaturated fatty acids (n-3 PUFA) such as eicosapentaenoic (EPA, 20:5n3) and docosahexaenoic (DHA, 22:6n3) acids. The objectives were to determine oil extraction efficiency using different solvent systems and the composition of extracted oil and spent krill following extraction. Extraction efficiency was the highest (P < 0.05) for one-step extraction using freeze-dried krill with 1:12 or 1:30 krill:solvent ratio (w:v) compared to Folch, Soxhlet, and conventional two-step extraction. Extracted oils contained predominantly phospholipids (20–33%), polar non-phospholipids (64–77%), and minor triglycerides (1–3%). Triglycerides contained much less (P …

Calcium platinum(IV) oxide has been synthesized from a flux and structurally characterized by single-crystal X-ray diffraction. It is isostructural with Sr4PtO6 [Randall & Katz (1959). Acta Cryst. 12, 519-521] and Ba4PtO6 [Wilkinson & Cheetham (1989). Acta Cryst. C45, 1672-1674].

The title bismuth-iodide compound, [Bi2I6(C12H8N2)2], has been synthesized solvothermally by reacting BiI3, Mn(CH3COO)2·4H2O, and 1,10-phenanthroline in an ethanol/water solvent mixture. The compound contains two bismuth centers that are each coordinated by a phenanthroline ligand and two terminal iodide ligands, and the bismuth centers are bridged via two additional iodide ligands to form a molecular dimer. The asymmetric unit of the compound consists of one half of a single dimer molecule located on a crystallographic inversion center.

The structure of the compound Ba1 + xNixRh1 - xO3 [x = 0.1170 (5)] has been analyzed at room temperature within the (3 + 1)-dimensional superspace approach using single-crystal X-ray diffraction data. Two different models are presented, the compound is refined as modulated composite as well as modulated-layer structure. In both models discontinuous atomic domains are applied to describe the structural modulations. While the first approach stresses the pseudo-one-dimensional constitution, the latter highlights the layered character of these structures.

InFeO3 is isostructural with the recently reported InMnO3. The structure of InFeO3 contains layers of In-O octahedra and Fe-O trigonal bipyramids. The trigonal bipyramids have ideal D34 symmetry. This unusual structure is unexpected within the context of known sesquioxide structures.
