Metal-Ligand Nano-Cages
This self-assembling structure has an interior cavity about 32 Å in diameter. It consists of 24 palladium ions, each of which is coordinated by 4 nitrogens, which are part of 48 dipyridylthiophene molecules. Such synthetic nano-spheres can be functionalized to create synthetic receptors and nanoreactors. Potential applications in sensing, catalysis, and drug delivery are being explored.

In the 1970s, an exciting discovery of a family of medicines was made by the Japanese scientist Satoshi Ōmura. One of these molecules, ivermectin, is shown in this artwork bound in the ligand binding pocket of the Farnesoid X receptor, a protein which helps regulate cholesterol in humans. This structure showed that ivermectin induced transcriptional activity of FXR and could be used to regulate metabolism.
Structure of Anticancer Ruthenium Half-Sandwich Complex Bound to Glycogen Synthase Kinase 3ß
G Atilla-Gocumen, L Di Costanzo, E Meggers. J Biol Inorg Chem. 2010 doi: 10.1007/s00775-010-0699-x
A crystal structure of an organometallic half-sandwich ruthenium complex bound to glycogen synthase kinase 3ß (GSK-3ß) reveals that the inhibitor binds to the ATP binding site via an induced fit mechanism utilizing several hydrogen bonds and hydrophobic interactions. Importantly, the metal is not involved in any direct interaction with the protein kinase but fulfills a purely structural role.
