Kinase Chemistry – Just a year and a half behind the times.


Posted by kinasepro on October 14, 2006

Hi Cyclacel,

Yah we’re reaching back to last year, because it looks like you’ve patented an Xray (WO2005047526) but your webby still says all you’ve got is a model. The title of the app is: “Use of crystal structure of Plk1 kinase in screening for inhibitors…” So what gives? The app just has the coords of a model, but one would presume that was derived from a bona-fide xray. The models below shows the important Cys residue and calls it “C67”. Kinasepro likes how you dress up the application giving data on wartmannin (180 nM), staurosporine (800nM), purvalanol (5uM), LY2940002(9uM), and quercitin (65uM) Thanks for describing the docking of some various compounds. I notice you’ve done this kind of thing before with the CDK program. Good show. More interesting then your picture the ‘homology model’ is LANL’s stock model to the right. (could you xerox these things a few more times before sending them to the lawyer? Sheesh)

Even more better is the figure of adenosine, and thioadenosine, thanks for that.

I especially like your body of matter application (WO2005042525) and thoroughly guffawed at the title page xray complete with coordinates. That’s an xray of the compound, btw, not the complex… There really is no better way of saying:“THIS ISN’T HOW IT BINDS!” Thanks again for the heads up anyways, but lots of people including you have already shown that aminopyrimidines bind more like I’ve shown in D of the above figure. 1FPU is a good exception, but I don’t see that going on here. Of course as with some of the last posts, these are really just KP’s own educated guesses.


I’ll say this much anyhow: You’re thiazolones have KP wondering more and more about what’s going on with Schering’s stuff though.

    Interesting post. I came across this blog by accident, but it was a good accident. I have now bookmarked your blog for future use. Best wishes. Rachael Ray.
