    How to Know When a New Target is Really a New Target

    This is an excellent article, and the title is self-recommending: “Common Pitfalls in Preclinical Cancer Target Validation”. The abstract speaketh the truth: An alarming number of papers from laboratories nominating new cancer drug targets contain findings that cannot be reproduced by others or are simply not robust enough to justify dr… Read More

    Thinking About Genetics and Disease

    Robert Plenge has an excellent post here, drawing on this recent paper from authors at Stanford. It’s on the idea of polygenic traits and disease, a very worthwhile subject considering what’s going on in the drug industry these days. I say that because I’ve been making the joke, for some time now, that if you were… Read More

    A New Diabetes Approach? Small-Molecule Screening Wins Again

    The molecular biology/chemical biology tools we have now are quite something, and have opened up whole areas of research that previously wouldn’t have been feasible. But as a chemist, I’m glad to say that there’s often still nothing like a small molecule. That’s one of the things I take away from this recent paper in… Read More

    Software Eats the World, But Biology Eats It

    I can strongly recommend this Bruce Booth post at LifeSciVC on computational models in drug discovery. He’s referencing Marc Andreessen’s famous “Why Software Is Eating the World” essay when he titles his “Four Decades of Hacking Biotech and Yet Biology Still Consumes Everything”. To tell you about where Bruce i… Read More

    Silently Affecting the Immune System?

    Here’s a new paper in Nature Chemical Biology that might be lifting the lid on a poorly-understood set of side effects. A multi-institution team (centered in Vienna) has taken peripheral blood mononuclear cells (PBMCs, basically the leukocytes and monocytes) from a single patient and looked for immunomodulatory effects of known drugs. (The si… Read More

    Free Compounds, Chosen By Software

    Here’s how the press release starts, and I’ll say this for it, it does get the reader’s attention: “Atomwise Inc. seeks proposals from innovative university scientists to receive 72 potential medicines, generated specifically for their research by artificial intelligence.” As you’d imagine, this is the sort of th… Read More

    Protein Degradation Time

    I’ve written a couple of times about the technique for selectively targeting and destroying proteins by forcing them to be ubiquitinated and hauled off to the proteosome. Both the Bradner lab (at Harvard/Dana-Farber) and the Crews lab at Yale found ways to do this a couple of years ago through broadly similar methods. You create… Read More

    Aggregator Aggravation, In a New Way

    Experienced drug discovery folks, particularly those that work early on in the process, will tell you that aggregation is one of the most common sources of false positive “hits”. This happens when the molecule in question bunches up with others of its kind and makes a larger species, particles of something that has different properties… Read More

    The ACS Journals Tighten Up Screening Standards

    Here’s an article (free access) in ACS Central Science on assay interference compounds, a contentious topic that has been aired here (and in many other places). This one, though, is authored by the editors-in-chief of all the relevant ACS journals and is appearing in all of them as well. People will argue about some of… Read More

    Fragment Screening in Cells – It’s Great

    I’ve very much been enjoying this paper, on fragment-based chemogenomics in whole cells. That’s the sort of blurb, I admit, that’s probably going to make you immediately want to read the rest of the paper, or immediately go do something else (all the way up to “podiatrist appointment”). And I understand those impulses. Read More
