Hello Exelixis,

Kinasepro must lament that many of your claimed compounds he’s seen before. They appear in the recent Kirin application which published a mere 7 days before yours. WO2006104161 (published 10/5/06) Ooooh, 7 Days? I haven’t figured out the priority dates but you guys probably need a beer right about now, eh? Hopefully everybody signed their notebooks…

Sure there’s probably enough room room in the c-Met sandbox for both Excelixis and Kirin to play. Both groups appear to have found interesting heterocyclic tail pieces, and the Excelixis application relies less heavily on the acyl-ureas claiming also some things like phenethyl oxalamides, and a noteworthy benzothiazole-amide (scheme on p142-144).

Mostly this is just a continuation of: WO2005030140 where they were looking at the quinazoline analogs. Bit of a snoozer if you ask me, but KP does like some of your mesylate intermediates:

Somebody should write a review on morpholine isosteres.
