R & D @ B I

Posted by kinasepro on September 13, 2008

With BIRB-796 a distant memory, BIBW-2992 in ph3 and given the new name Tovok, BIBF-1120 headed into ph3 and given the name Vargatef,  BI-2536 in multiple Ph2s, a new Ph1 Aurora inhibitor, and another backup PLK1 inhibitor undisclosed, but likely in-clinic or clinic-bound – what could possibly be next?

I can haz pyrimidines

PDK mod prolly from Berlex

BI ‘n’ Aurora B

Posted by kinasepro on February 12, 2007

Boehringer-Ingelheim’s got a series of 5-lipophile-substituted-pyrimidines claimed as ‘Aurora B’ inhibitors.


15 inventors / 148 examples / no data

Hi BI, nice IKK inhibitors. These seem to hav evolved from alcohol hits first published in that ’03 application, which led to these aminoalcohols (WO2005056562).

Hi Boehringer Ingelhiem, KP likes the BI piperidines/ pyran / cyclohexyl wrinkle on the quinazoline EGF compound series. More derivatives in this continuation, otherwise nothing much to see here.

Move along.

Hi BI, More aminopyrimidines?

More the merrier I say. No sulfur this series, but Kinasepro likes the ground you cover with these applications: EP1598343 (published 11/25/05)

The amine in example one is nice, and thanks for the experimental. (1>reductive amination 2>Pd/C, p54.) It looks as though you like it too, because it and some isosteres are heavily represented in the later generations. EP1630163 (published 3/1/06)

Not the standard solvent exposed yada-yada, though quite a bit different from the Amgen imidazalones. Second and a half generation: WO2006021378 (published 8/19/06) Looks as though you just realized the anilines were active, and rushed to cover them in this app. Hoho, otherwise this is the same as the previous, just reverse the [L]&C=O in the previous Markush.

Third Generation: WO2006021547, and WO2006021548 (Published 3/2/06) Kinasepro’s trick elbow tells him BI is closing in on something though he thinks you should have a talk with the guy who put your patents together. Is the the jumbled up A, R2, and R3 on page 43 enough to invalidate? Neh, but KP hopes your attorney lays off the 3-Heineken lunches. Nice set of amines anyhow. 

smiles: yah, KP is trying a new thing with smiles.  to see if they’er searchable.
