From: WO/2006/010127 and recently described as inhibiting PKC.

Go ahead, laugh it up – but hey, it could always be worse:

Selective vs. Nonselective

Posted by kinasepro on October 25, 2007

There are a handful of ways to visualize selectivity among kinase inhibitors after you’ve had them Profiled.

The gold standard has become the Ambit panel:

 

(from the Nature Biotech paper)

A simple chart will get the job done:

(INNO-406 / NS-187, from Blood 05, 3948)

or a heat map like Amphoras’:

If you prefer a reductionist approach you’ve always been able to take it down to a single number with fold shift from its nearest neighbor.

And now it looks like there may be a statistically more meaningful number with the recent J Med Chem on applying the Gini Coefficient to kinase inhibitor selectivty. In case you missed it, check out the spreadsheet in the supporting info.

Weekend Reading

Imagine that, a Chem Rev I’m actually going to read?

Cl – – – – O

Posted by kinasepro on October 18, 2007

I am somewhere between faithless and agnostic on the role of through space ‘halogon bonding’, but earlier a reader pointed us towards a review on the subject from within the recent kinase-thematic issue of Current Topics in Medicinal Chemistry.

With this as a backdrop, here’s another very interesting structure from SGC: 2VAG is Clk1 bound to a dichloroindole. If it is indeed as potent as has been suggested to me, then I might be moving towards believer status.

O=C(C(N2C)=C(/C(C#N)=C\N)C1=C2C(Cl)=C(Cl)C=C1)OCC

The animation shows their earlier 1z57 with Hymenialdisine, a somewhat more traditional kinase inhibitor.
