The pyridine hydrazone JIB-04, a specific inhibitor of Fe- and α-ketoglutarate-dependent, O2-activating histone lysine demethylases, is found to block the binding of O2in KDM4A through an O2-consumption assay, X-ray crystal structure data, and molecular modeling.

Statistical Survey

The Cambridge Structural Database (CSD) now contains data for more than a quarter of a million small-molecule crystal structures. The information content of the CSD, together with methods for data acquisition, processing and validation, are summarized, with particular emphasis on the chemical information added by CSD editors. Nearly 80% of new structural data arrives electronically, mostly in CIF format, and the CCDC acts as the official crystal structure data depository for 51 major journals. The CCDC now maintains both a CIF archive (more than 73000 CIFs dating from 1996), as well as the distributed binary CSD archive; the availability of data in both archives is discussed. A statistical survey of the CSD is also presented and projections concerning future accession rates indicate that the CSD will contain at least 500000 crystal structures by the year 2010.

X-Ray Crystal Structure Analysis of Substituted 5-(2,3-Dihydro-7-benzofuryl)- 2-methylpyrazolo[4,3-d]pyrimidin-7-one (iso-Biagra) [1]

X-ray crystal structure data for the substituted 5-(2,3-dihydro-7-benzofuryl)-2-methylpyrazolo[ 4,3-d]pyrimidin-7-one (3) reveal that the two bicyclic heteroaryl systems show no coplanarity along their joint C (5) - C (11) axis with an interplanar angle of 9.6°. Nonetheless, the spatial interatomic distance for O(17)-N(6), determined as 2.73 A, allows the formation of a relatively weak intramolecular hydrogen bond between the pyrimidinone N(6)-H and the O(17) lone pair of the dihydrobenzofuryl moiety.

The 125Te Mössbauer spectra of a number of Te(II) and Te(IV) complexes with sulfur-containing ligands have been measured. The Te(II) compounds exhibit large quadrupole splittings of 12.4 to 15.2 mm s−1 and isomer shifts (125I/Cu) of + 0.33 to + 0.91 mm s−1. These data are interpreted as evidence for the incorporation of some 5s character in the bonding scheme for several of the compounds, consistent with the interpretation of X-ray crystal structure data. For the Te(IV) compounds 6, 7, and 8 coordinate molecules have been studied containing tellurium in distorted octahedral, pentagonal bipyramidal, and dodecahedral coordination.
