Derek Lowe's commentary on drug discovery and the pharma industry. An editorially independent blog from the publishers of Science Translational Medicine. All content is Derek’s own, and he does not in any way speak for his employer.
Roald Hoffmann and Jean-Paul Malrieu have a three-part essay out in Angewandte Chemie on artificial intelligence and machine learning in chemistry research, and I have to say, I’m enjoying it more than I thought I would. I cast no aspersion against the authors (!) – it’s just that long thinkpieces from eminent scientists, especial… Read More
To what extent can scientific discovery be automated? Where are the areas where automation can make the biggest contribution to human efforts? These questions and a number of others are addressed in a very interesting two-part review article on “Automated Discovery in the Chemical Sciences”. The authors, from MIT, are well-equipped (in… Read More
This new paper shows one reason why it’s so tricky to calculate compound binding in an active site (which is what we’d want to do in order to do effective in silico virtual screening). The authors (a multicenter team from York, Demuris, Vernalis, and St. Jude) are looking at a virulence protein from H. influenzae… Read More
There were some headlines the other day about the “first AI-discovered drug”, so that should send us to the work in question to see what’s going on. The company in question is called Deep Genomics, and here’s what its founder has to say: “Making drugs has traditionally been a gambling game. Big Pharma is throwing… Read More
One of the reasons that people in or near this business can write such gaudy press releases is that it has so many moving parts. That lets everyone claim that the part that they’re addressing is Crucial. Think of a car: the wheels are indeed key to mobility, but so is the engine. As is… Read More
OK, today’s blog post is going to be even weirder than usual – we’re going to wander off into quantum mechanics. And into a particular borderland of it where have been a lot of interesting hypotheses and speculations, but plenty of hand-waving hoo-hah, so it’s important to realize the risks up front. But here we go. Read More
Here is an interesting paper in Nature Biotechnology on computational drug design, and if you read it without reading any of the accompanying articles about it, you will have a perfectly good time. There are things that you will be impressed by, and there are things that you will argue with, but that’s how most papers… Read More
Here’s another step along the way to automated synthesis, in a new paper from MIT. The eventual hope is to unite the software and the hardware in this area, both of which are developing these days, and come up with a system that can produce new compounds with a minimum of human intervention. Let’s stipulate… Read More
Here’s a ring system that you’ve never used before – the cyclopropyl system in purple at the end of the row in the diagram at right. It’s described in this paper from GSK-Stevenage as a new morpholine isostere. A 4-morpholino-pyrimidine hinge binder core is preferred in many PI3K and PIKK inhibitors, but the team was… Read More
Since I was just blogging the other day about a machine-learning paper that worked its way through decades of abstracts for materials science papers, this news is timely. Carl Malamud and a team at Jawaharlal Nehru University in New Delhi have assembled a rather huge repository of journal articles (they’re aiming for about 73 million of… Read More
