US20060241149

To Kinasepro, the real personality behind Sorafenib, is the part about how they optimized against RAF only to find out later that it was the VEGFR2 and PDGFR-b activity that was driving the efficacy. Hmm, somehow they don’t quite put it that way in the Nature Reviews DD article… Bayer has a couple PDB’s deposited for Sorafenib / BAY439006 / Nexavar (RAF; 1UWH, 1UWJ), but if you want a Urea bound to VEGF all you’ve got is 1YWN. Does this mean GSK > SKB? I tend to think US20060241149 will put an answer to that.

Yah yah 1YWN was a GSK Japan offering, while the current application is a King of Prussia SKB claim but what’s this new application all about? Mmmmm, I think you’re going to have to do better then a little TIE2 activity to make me a believer.

So I here you thinking, ‘aww, c’mon the Piperazines are cool!’ Bleh, been there done that – and the fused 5? Yah, yah I guess but hasn’t somebody already been there? I hope this is one of those applications dropped just to prevent someone else from going there… Oh, but if you’ve been wondering why you keep seeing these pyridines bearing a 2-methyl carboxamide it’s because if the pyridyl binds the hinge, you get a modest bump in activity, and:


O=C(NC3=CC=C(CN4CCN(C)CC4)C(C(F)(F)F)=C3)N(CC5)C(C5=C2)=CC=C2OC1=CC=NC(C(NC)=O)=C1 O=C(NC3=CC=C(Cl)C(C(F)(F)F)=C3)NC(C=C2)=CC=C2OC1=CC=NC(C(NC)=O)=C1

and DE102005020105. Guten Tag Schering AG,

Further along the road with the thiazolidinones, eh?  I like the title: New thiazolidinone without basic nitrogen, their production and use as drugs

Kinasepro is always happy to see more Plk1 inhibitors, but hey I’ll admit that I haven’t a clue whats going on with these – and now consider an earlier post on your analogous series, ummm, wrong. The only PDBs that give KP a hint as to what could be going on here are from some compounds bound to PI3K: 2A4Z, and 2A5U. O=C(N(CC)/C(S2)=C(C(NCC(F)(F)F)=O)\C#N)/C2=C/C1=C(C)N=CN1 O=C(N(CC)/C(S2)=C(C(NCC#C)=O)\C#N)/C2=C/C1=CC=C(N3CCCC3)C=C1
