More on the NIH's Molecular Libraries Program
I last wrote about the Molecular Libraries program here, as it was threatened with funding cuts. Now there's a good roundup of opinion on it here, at the SLAS. The author has looked over the thoughts of the readership here, and also heard from several other relevant figures. Chris Lipinski echoes what several commenters here had to say:
Lipinski notes that when the screening library collection began the NIH had little medicinal chemistry experience. "I was a member of an early teleconference to discuss what types of compounds should be acquired by the NIH for high-throughput screening (HTS) to discover chemical biology tools and probes. Our teleconference group was about evenly split between industry people and academics. The academics talked about innovation, thinking out of the box, maximum chemical diversity and not being limited by preconceived rules and filters. The industry people talked about pragmatism, the lessons learned and about worthless compounds that could appear active in HTS screens. The NIH was faced with two irreconcilable viewpoints. They had to pick one and they chose the academic viewpoint."
He says that they later moved away from this, with more success, but implies that quite a bit of time was lost before this happened. Now, we waste plenty of time and money in the drug industry, so I have no standing to get upset with the NIH about blind alleys, in principle. But having them waste time and money specifically on something that the drug industry could have warned them off of is another thing.
In the end, opinions divide (pretty much as you'd guess) on the worth of the whole initiative. As that link shows, its director believes it to have been a great success, while others give it more mixed reviews. Its worth has surely grown with time, though, as some earlier mistakes were corrected, and that's what seems to be worrying people: that the plug is getting pulled just when things were becoming more useful. It seems certain that several of the screening centers will not survive in the current funding environment. And what happens to their compounds then?
