OK, here's how I understand the way that medicinal chemistry now works at Pfizer (PFE). This system has been coming on for quite a while now, and I don't know if it's been fully rolled out in every therapeutic area yet, but this seems to be The Future According to Groton:

Most compounds, and most actual chemistry bench work, is apparently going to be done at WuXi (WX) [or perhaps other contract houses?] Back here in the US, there will be a small group of experienced medicinal chemists at the bench, who will presumably be doing the stuff that can't be easily shipped out (time-critical, difficult chemistry, perhaps even IP-critical stuff, one wonders?) But these people are not, as far as I can tell, supposed to have ideas of their own.

No, ideas are for the Drug Designers, which is where the rest of Pfizer's remaining medicinal chemistry head count is to be found. These are the people who keep trac of the SAR, decide what needs to be made next, and tell the folks in China to make it. It's presumably their call, what to send away and what to do in-house, but one gets the sense that they're strongly encouraged to ship as much stuff out as possible. Cheaper that way, right? And it's not like there's a whole lot of stateside capacity, anyway, at this point.

What if someone working in the lab has (against all odds) his/her own thoughts about where the chemistry should go next? I presume that they're going to have to go and consult a Drug Designer, thereby to get the official laying-on of hands. That process will probably work smoothly in some cases, but not so smoothly in others, depending on the personalities involved.

So we have one group of chemists who are supposed to be all hands and no head, and one group that's supposed to be all head and no hands. And although that seems to me to be carrying specialization one crucial step too far, well, it apparently doesn't seem that way to Pfizer's management, and they're putting a lot of money down on their convictions.

And what about the whole WuXi/China angle? The bench chemists there are certainly used to keeping their heads down and taking orders, for better or worse, so that won't be any different. But running entire projects outsourced can be a tricky business. You can end up in a situation where you feel as if you're in a car that only allows you to move the steering wheel every twenty minutes or so. Ah, a package has arrived, a big bunch of analogs that aren't so relevant any more, but what the heck. And that last order has to be modified, and fast, because we just got the assay numbers back, and the PK of the para substituted series now looks like it's not reproducing. And we're not sure if that nitrogen at the other end really needs to be modified any more at this point, but that's the chemistry that works, and we need to keep people busy over there, so another series of reductive aminations it is. . .

That's how I'm picturing it, anyway. It doesn't seem like a particularly attractive (or particularly efficient) picture to me, but it will at least appear to spend less money. What comes out the other end, though, we won't know for a few years. And who knows, someone may have changed his or her mind by then, anyway.
