Towards more robust and efficient methods for the calculation of Protein-Ligand binding affinities
Biological processes often depend on protein-ligand binding events, so that accurate prediction of protein-ligand binding affinities is of central importance in structural based drug design. Although many techniques exist for calculating protein-ligand binding affinities, ranging from techniques …

Synthesis of fluorescent analogues of a-tocopherol as ligands for the human a-tocopherol transfer protein (a-TTP) /
… from C-2 of the chroman ring while retaining key binding features of the natural ligand. These compounds were prepared starting from (S)-Trolox® acid VIa esterification, protection, and reduction producing the silyl-protected (S)-Trolox aldehyde that was coupled using Wittig chemistry to different …

Synthesis and characterization of diphosphine ligand substituted osmium and ruthenium clusters.
… the bridge-to-chelate isomerization of the dppe ligand in H4Ru4(CO)10(dppe) have been investigated by UV-vis and NMR spectroscopies over the temperature range of 308-328 K. The isomerization of the ligand-bridged cluster 1,2-H4Ru4(CO)10(dppe) was found to be reversible by 31P NMR spectroscopy, …

Substitution chemistry of the cobalt complexes RCCo3(CO)9 (R = H, CHO) with the diphosphine ligand: 4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (bpcd). Syntheses, X-ray structures and reactivity.
… CHO (1), H (3)} and the redox-active diphosphine ligand 4,5-bis(diphenylphosphino)-4-cyclopenten-1,3- dione (bpcd) leads to the replacement of two CO groups and formation of RCCo3(CO)7(bpcd) {R = CHO (2), H (4)}. Clusters 2 and 4 are thermally unstable and readily transform into the new P-C bond …

Evidence that ARNT plays a role in the regulation of the immunoglobulin heavy chain enhancer and identification of a putative ARNT ligand
… our investigation we discovered a putative ARNT -binding ligand that increases DNA-binding activity of the ARNT homodimer. This ligand was partially characterized by UV crosslinking studies and a variety of biochemical studies using electrophoretic mobility-shift assays. Preliminary data suggests …
