    Metformin and Exercise

    I’ve written about metformin quite a few times over the years on the blog, and for several reasons. It is (for starters) obviously a frontline drug for treatment of Type 2 diabetes, a condition that has unfortunately become more and more common in the world as the world puts on more and more weight. (Side… Read More

    The Secret Life of the Insulin Receptor

    You’d think that we would understand the workings of something like the insulin receptor by now, wouldn’t you? I worked in the metabolic disease area for several years, and I can give you the canonical version of its activities as it relates to insulin levels and glucose handling out in the canonical tissues (muscle, adipose).

    Zafgen: Will There Be a Third Act?

    A few years ago on this blog, I wrote several times about a small company called Zafgen and their unusual epoxide-based chemical matter (beloranib) that was in development for the rare Prader-Willi syndrome. That’s a genetic disorder that includes, among many other problems, constant hunger (with the complications that you’d expect fro… Read More

    Exercise And Its Signaling

    It’s a truism among metabolic researchers that if you could find a drug that simulates the effects of exercise you would be very happy with the market for it. But what causes the effects of exercise? That’s one of those simple questions that members of the general public might think that they know the answer… Read More

    PI3K Inhibitors: You’re Doing It Wrong

    Now here’s an interesting connection between cancer and metabolism, with what look to be direct implications for therapy. A large research team (mostly working out of Weill Cornell) reports some new and important details about PI3K inhibitors, a class of kinase inhibitors that has seen a very large amount of development work indeed. I’v… Read More

    Type 2 Diabetes May Be a Protein Misfolding Disease

    Here’s a paper that will not calm anyone down about the possibility of prion-like diseases. Those, as many will know, are spread by misfolded proteins that, on contact, template others to follow their example. I last wrote about this field a couple of years ago, when examples appeared of transmissable amyloid pathology in humans, spread… Read More

    AMPK: Time To Think Hard

    AMP-activated protein kinase, now that’s an enzyme for you. It sits at the center of a cell’s metabolic switchboard, and if you’re talking about anything to do with the response to levels of fuel like glucose or fatty acids and determination of their downstream fates, then AMPK is almost certainly crucial. Activating the enzyme se… Read More

    Two Diabetes Drug Mysteries

    Here are some data to file under “Drugs do things that we don’t expect”. The SGLT-2 inhibitors are a class of diabetes medications that work by inhibiting the sodium/glucose transporter 2 protein in the kidneys. That keeps glucose from being reabsorbed there; instead, more of it is removed in the urine, and that lowers circulating… 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

    Zafgen’s Second Act

    F. Scott Fitzgerald was a very good writer, but one of his most famous lines is about as wrong as it can be. It’s actually a cliché to point out the complete wrongheadedness of “There are no second acts in American lives”, such are the huge number of counterexamples. And that goes for biopharma, too. I’ve written… Read More
