Vertex and c-Met

Posted by kinasepro on June 12, 2007

A reader asks what’s up with these, which got me wondering the same. An interesting new c-Met application from Vertex (WO/2007/064797) likely stems from a screening hit off of a related GSK3 series: WO/2004/058769.


There are a number of examples trying to get away from the phenol, things like prodrugging, and as many isosteres as you shake a stick at. A few interesting modifications appear to produce < 100 nM Ki compounds.

As for how they bind? Well… your guess is as good as mine, but here’s mine: (oops – it’s since come out that the phenol in this motif hits the hinge. so this was a cute idea but wrong)


Just what’s up with the phenol? I have some ideas, but its kind of tricky to guess given the mobility of the a-loop.

    Is there a problem with a free phenol?

    Only if protein binding, glucuronidation, and poor permeability bother you…

    Yeah, this is completely based on sugen patent

    PCT Int. Appl. (2005), 47 pp. CODEN: PIXXD2 WO 2005010005 A1 20050203

    which was based on tetracyclic compounds from sugen patent

    PCT Int. Appl. (2005), 73 pp. CODEN: PIXXD2 WO 2005004808 A2 20050120 CAN 142:155983 AN 2005:55025

    which was based on earlier isatine hydrazone sugen patent

    PCT Int. Appl. (2005), 189 pp. CODEN: PIXXD2 WO 2005005378 A2 20050120

    which was based on high-throughput hit from screening Kalamazoo compound collection

    I should add that your binding mode is wrong, the explanation of how it binds is in the comment on today’s J&J post.
