    GPCRs: Peeling The Onion Some More

    I like to say that when I was first working on G-protein coupled receptors (GPCRs) as drug targets, that after I while I thought I really understood a lot of what was going on. But that was the peak. Further experience eroded that confidence, and even though I’ve learned a lot more about them over… Read More

    How Close is Cryo-EM To Riding Over the Horizon?

    OK, all this cryo-electron microscopy stuff is great, new protein structures, things that are huge, that can’t be crystallized, fine, fine: but when, the medicinal chemists in the audience ask, will we be able to use it for structure-based drug discovery? This new review tries to answer just that question. The first thing that you… Read More

    Only Bind

    Here’s a new piece by Stuart Schreiber that lays out a shift in thinking that many people in the chemical biology field have been experiencing over the last few years. Medicinal chemists are used to making functional drug candidates – and by “functional” I mean compounds that make protein targets do something. For an enzyme… Read More

    PAINs Filters In the Real World

    Here’s a look (open access) at Eli Lilly’s screening collection in terms of PAINS filters, and there are things for everyone to argue about in it. The entire concept of these filters has been occasion for argument, of course. Allow me to caricature some of the opinions that you hear in these: at one extreme, it… Read More

    Combination Screening, Scaled Up

    Here’s another one for the Brute Force File, always noting that brute repetitious force is what machines are here for. A joint MIT/Broad Institute effort reports on a platform for combinatorial drug screening in nanodroplets, in this case looking for known compounds that potentiate the effect of antibiotics on gram-negative bacteria. Testing… Read More

    Looking Way Down Into the Cells

    Pharmacokinetics – the study of how drugs are taken up, distributed, metabolized, and cleared – is obviously a key part of drug development. Every drug substance gets handled somewhat differently by the human body, and these differences can completely determine whether you’ve got an effective therapy or not. But the tools we have… Read More

    Relay Calculates Its Way Through

    Bloomberg has a feature on Relay Therapeutics, who are just a few blocks away from me (and where several former colleagues of mine work). It’s a nice writeup, and also features a (relatively rare) spotlight on David Shaw of D. E. Shaw research. He’s one of those guys that you’ve likely never heard of unless… Read More

    Silicon In Drug Molecules, Revisited

    Here’s an update to a post from last year about silicon in drug-like molecules. The Denmark group at Illinois has investigated a range of silicon-containing heterocycles, providing both synthetic routes into the (mostly unknown) structures, and looking at some basic pharmaceutically relevant properties. There’s a lot of work in this pap… Read More

    Give It to the Machines

    Here’s another paper for the automated med-chem files. A group at Merck (Boston) reports a combination of very small-scale automated synthesis with a screening assay in situ (no purification). You may be wondering how that works, or how it can possibly work, especially when you hear that the nanoscale reactions are transition-metal catalyzed. Read More

    A New Method to Weigh Biomolecules

    I’m always happy when a new analytical technique is worked out, especially one that’s applicable to biological binding assays, doesn’t require labeling of the species involved, and is orthogonal to the existing methods. We need all the reality checks we can get, and this one (reported by a large multinational team led out of Oxfor… Read More
