Who cares about the Roche p38 inhibitors?

Posted by kinasepro on September 5, 2008

Probably a few less people in PA then a few months ago, eh?  But this one’s been getting press recently:

PDB Update

Posted by kinasepro on October 16, 2007

2R9S is Jnk3 bound in an unusual fasion to a quinoline inhbitor:(Reminds me a little of Vertex’s 2ok1) (BMCL)

2NPQ is p38 bound to 2 molecules of octyl-glucoside:

GSK and Ranbaxy in the P38 game

Posted by kinasepro on April 5, 2007

Earlier Ranbaxy had WO/2006/082492 and now its: WO/2007/036791. Add to that GSK has 2 oral P38 inhibitors in the clinic but despite some crafty wording of a recent Ranbaxy press release, the current clinical batch wasn’t an Indian invention. It looks as though GSK has shipped finding more backups overseas.


SB681323: Phii: COPD, Neuropathic pain
GW856553: Phii RA; RA; COPD;


One of them is likely from WO/2006/134382 (compound on the left) The other? Not so obvious. There’s a number of GSK p38 applications, but my guess is it hails from the pyrimidopyridone scaffold: Something like: WO/2003/088972 (above) or WO/2006/104915
