Apparently, polyoxometalates have been found to be "very powerful inhibitors of a specific protein kinase, CK2, an enzyme that is overactive in a number of cancers." I say apparently, since it was reported in the journal "Chemistry and Biology," a journal to which I do not have access. I only know of the study because of
this press release. Polyoxometalates are large anionic clusters generally consisting of transition metals and oxygen. A good description can be found
here. This study is of particular interest to me since I have worked with polyoxometalates of V, Mo, and W in the past. I admit to having lost touch with them over the years, mostly because my work at that time involved aqueous polymetalates (I love aqueous chemistry!) and subsequent research on polymetalates had begun turning to derivatives which were only soluble in organic solvents. So it was with some delight that I discovered that aqueous polyoxometalates had reappeared in the literature. Unfortunately, the press release gives very few details about the particular polyoxometalates involved or what kind of chemistry is occurring. In fact, I am only assuming that these are aqueous species since they are being used in biological systems. In any case, since aqueous chemists seem to be vastly outnumbered by non-aqueous chemists (I was definitely in the minority in the U of Illinois Inorganic Chemistry department), I am always happy to see a paper on aqueous chemistry that is at least somewhat mainstream.
Are there any aqueous inorganic chemists out there reading this blog?

My family and I will be leaving tomorrow to visit my parents in Springfield, Missouri for 5 days. I've talked about
Springfield before, so it's always a fun trip, but I won't be updating the blog until next week. In the meantime, here is the previously promised picture of my garden (or at least a small part of it).

Using water as a solvent always makes me feel...dirty. *shudder*
If you can email me the DOI for that paper, I'll see if my university has access. ;)
Wow, your garden is gorgeous!
I'm not technically a chemist, I'm a Chem E. I work in water/wastewater treatment. So lots of aqueous chemistry, but it's mostly of the boring oxidize-and-precipitate variety (Fe, Al with coprecipitates of As, Cd, Zn, etc). Not nearly as chemistry-y as you.
Well as a former U of I organic chemist I agree working in water is weird, but as an inorganic coordination chemist working on in vivo imaging agents its become routine. A huge variety of coordination compounds are used in imaging and radiotherapy all of which are prepared and function in water.
polymetalates in aqueous media have several aplications in electrocatalysis.
