    Treatment With MDMA

    A theme that I return to every so often on the blog is the degree to which we don’t understand the molecular mechanisms of psychiatric syndromes. I’ve found that many people outside of the biomedical world are surprised by this – depression, for example, is something that’s distinctive enough, widespread enough, and certainl… Read More

    Oligonucleotides And Their Discontents

    I remember being at a chemistry meeting in New Jersey back in around 1990 or 1991, where a speaker mentioned in passing that most of the people in the room would probably soon be offered a chance to move to California and work for some small company trying to develop antisense drugs. There was a… Read More

    How Antidepressants Work, At Last?

    Over the years I’ve very much enjoyed being startled by the scientific literature, and there haven’t been many times when I’ve been more surprised than I was this morning. I’ve been making references on this blog for years about how we don’t even know how antidepressants work, but if this new paper is correct, then… Read More

    More Things to Do With mRNA

    After yesterday’s post on mRNA vaccines and RNA mechanisms, I wanted to highlight a completely non-coronavirus application that has recently appeared in the literature. It’s from BioNTech, the German company who’s been working with Pfizer on one of the two mRNA coronavirus vaccines, of course, but they have other therapeutic inter… Read More

    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

    Opioid Signaling: Think Again

    Opioids are some of the most effective and most problematic drugs in the entire pharmacopeia. For severe, intractable pain we really have nothing to match them, despite decades of searching for alternatives. The history of research for new pain medications itself calls for pain medication, because it is a tapestry of expensive late-stage clinical f… Read More

    Another AI-Generated Drug?

    I see that there’s press coverage today of “the first AI-generated drug” to go into human trials. Some will recall this similar claims have been made before, so what exactly are we looking at? The compound is DSP-1181, from a collaboration between Sumitomo and the startup Exscientia (out of Dundee). It’s a long-acting 5-HT1a… Read More

    Another Shot at Major Depression Fails

    This is a big day for clinical trial data, and unfortunately it didn’t get off to a very good start. Everyone is waiting for more data on Biogen’s Alzheimers program later today, but another anticipated trial has already read out. Sage Therapeutics made quite a few headlines in 2017 and 2018 when their trials of… Read More

    Human Brains and Mouse Brains: So Similar, So Different

    Well, it’s inadvertently been sort of a Neuroscience Week here. This latest paper is a very interesting addition to the field indeed, just out from a very large team centered at the Allen Institute, where some rather large-scale work in the field has been done in the past. This one continues their tradition: it’s a… Read More

    Unfolding the Unfolded Protein Response.

    When you look closely at cellular biochemistry, what you see are a lot of amazing processes that are surrounded by amazing amounts of redundancy, backups, patches, and accumulated tweaks and fixes. That’s evolution for you; these things have been piling up for a billion years or two, and we’re all the descendants of the critters… Read More
