Any news on the cytokine receptor small molecule molecule agonist front? Have you spoken with IR recently about this. I have been doing a lot of reading in the cytokine agonist area and I think this is close to impossible. I'm also curious about the issue of species selectivity of the compound(s), as the agonist binding pockets should be largely similar. Unless, of course, as for certain other peptidergic G-protein coupled receptors there are distinct receptor protein residues that are only directly interacting with the small molecule and not with the natural agonist ligand. Also, Henry, do you know whether there are small molecule antagonists that block natural agonist binding? I find it curious that Robinson did not say mauch about the small molecule program at the annual meeting. On the other hand, he was quite suberb on his discussion of the various extant programs, I am happy to say.
