    Vibrational Modes, For Real

    I suppose I deserve this one. Some years ago on the blog, I wrote about my days in grad school having to learn about symmetries and vibrational spectroscopy. Sparingly has that knowledge come in handy since then, but the course is still a vivid memory for me, since that’s the clearest example I had yet… Read More

    An Expensive Choice for Duke

    You may have seen the headlines about a large settlement ($112.5 million) that Duke University is paying the government. This goes back to Erin Potts-Kant, a clinical research coordinator at Duke Health, as well as (former) professor William Foster and (former) chief of the Pulmonary Division Monica Kraft. The details are many, and some of them… Read More

    Sneaking Proteins Into Cells

    Now here’s a weird and rather startling paper. One of the things that people in this line of work spend a lot of time on is getting things into living cells. Small molecules often slide in, one way or another (although, to be honest, our detailed understanding of how they do that could use some… Read More

    What Those Degraders Are Actually Doing

    Since targeted protein degradation is such a hot topic these days, this paper (which adds to the results obtained by this one) should get some interest. It’s a report of a detailed look at the kinetic behavior of several bifunctional degraders – and there’s a lot of kinetic behavior to look at. That’s because you’re l… Read More

    Virtual Screening – As Big As It Currently Gets

    This new paper on “ultra-large” virtual screening is well worth a look in detail. We find a great many lead compounds in this business by random screening of compound libraries, and virtual screening is (as the name implies) the technique of doing this computationally instead of with hundreds (thousands) of sample plates and tireless ro… Read More

    The Clinic Giveth And Most Definitely Taketh Away

    There have been some pretty dramatic clinical trial results coming out recently, and unfortunately drama is a variable that can take either a positive or a negative sign in front of it. On the plus side, MacroGenix, a company that not many people had been paying attention to, announced results of a head-to-head trial of… Read More

    A Toxicological Flag

        Here’s a caution from a new paper out of Manchester. The group had been synthesizing inhibitors of PARG (poly-ADP ribose glycohydrolase), an enzyme involved in DNA repair. The general chemotype is shown at right, but there are a number of variations. That fluorine is a new addition, though. The corresponding cyclopropylmethyl se… Read More

    Come One, Come All to These Kinases

    Why do some proteins in a family prove very hard to target, while others bind a whole list of inhibitors? This paper takes a look at a particularly dramatic example in the kinase field. That’s a good place for studying such things, since there are a lot of kinases out there, and a lot of… Read More

    We Have Given People Amyloid Disease

    Unfortunately, it’s time to talk transmissible protein pathology again. That’s the unnerving idea that misfolded proteins can, under some conditions, act as infectious agents (prions are the most famous examples and the most widely-used name for these). I wrote in 2015 about a particularly alarming possibility. It’s known that up… Read More
  • Architecture and Productivity: Four Theses

    I certainly enjoyed this review of a new book, Laboratory Lifestyles, in Nature. This is a look at research buildings and the behavior of scientists in them, and will for many reopen a lot of arguments. Open offices? Open-plan lab space? Where do the break areas go, and the conference rooms? What do they look… Read More
