    Slipping Into the Brain

    We’ve got a lot of longstanding technical difficulties in the drug development business – things that we’d really like to be able to do, but can’t quite manage to find any general solutions to. Measuring drug concentrations inside cells (or parts of cells), that’s one. Predicting human toxicology for a new compound is… Read More

    Famotidine, Histamine, and the Coronavirus

    Here’s a new preprint on a drug-repurposing effort that many people have been wondering about: famotidine, the histamine antagonist that is sold under the brand name of Pepcid. There have been some retrospective data that have suggested that famotidine use can have a beneficial effect on the course of the disease, and a controlled trial… Read More

    Monoclonal Antibodies for the Coronavirus (Updated May 5th)

    Antibodies as a therapy Let’s have a look at what is (in my opinion) probably our best shot at a reasonably short-term targeted therapy against the COVID-19 epidemic: the possibility of using monoclonal antibodies. These can be developed more quickly than vaccines, and a lot more quickly than a new targeted small-molecule antiviral. Like ever… Read More

    Omeprazole As An Additive For Coronavirus Therapy

    One of the notable things about the current pandemic is the way that all our modern biology and analytical techniques are on display. Molecular biology, structural biology, bioinformatics, technologies like cryo-EM structure determination, fast sequencing, protein interaction screening and more – this is a real-time look at how basic biomedic… Read More

    Vitamin C and Immuno-oncology

    Linus Pauling was a fearsomely great scientist who is remembered by the general public for his advocacy of megadoses of Vitamin C, a favorite topic of his later in life. Infectious disease, cancer: Pauling advised gram amounts of ascorbic acid and had a lot of theorizing to offer about why that was beneficial. So while… Read More

    Idiosyncratic Tox

    It’s our high failure rate in clinical trials that makes the drug industry what it is. And two of the biggest factors in that failure rate are picking the wrong targets/mechanisms, and unexpected toxicity. The first is clearly a failure of our understanding of human biology, and the only remedy I can see for that… Read More

    Congo Red

    Many roots of organic chemistry, and of medicinal chemistry in particular, often originate in what might seem like an unlikely place: the dyestuff industry of the late 19th century. I had already known this to some degree, but writing the historical vignettes in The Chemistry Book really brought it home to me. And if you… Read More

    Membrane Surprises

    Drug discovery folks spend a good amount of time and effort dealing with cell membranes. Our drug candidates stick to them, get imbedded in them, might have to slip through them to get to their target proteins, or may target proteins that are localized in them, can get actively transported through them or actively pumped… Read More

    Drug Dosing

    First in humans! That’s a big step for a drug project – you’ve identified a clinical candidate with enough potency, selectivity, etc. to be a plausible drug, you’ve made it past toxicity testing (always a black-box cross-your-fingers exercise), and you’ve figured out a way to dose the stuff in human subjects. But how d… Read More

    Inside the Lipid Droplets

    Figuring out an unusual natural product’s activity can be a difficult but rewarding exercise. Deep evolutionary time has provided us with a bizarre range of chemical structures that are presumably not being synthesized by organisms for the sheer fun of it – these things are acting as signaling molecules, antifeedants, poisons for the co… Read More
