  • Click Chemotherapy

    So here’s an ambitious idea that’s about to get a hearing in human clinical trials. A startup called Shasqi is using click chemistry as a drug delivery method, and they have a new manuscript on the idea here at ChemRxiv. The idea is this: you produce a modified version of a hyaluronate biopolymer, decorated with… Read More
  • More Antibody Data

    Unfortunately, we’re getting a dose these days of “That’s why you run clinical trials”. Word came Monday evening (Peter Loftus in the WSJ, and a Lilly statement) that the ACTIV-3 trial being run by the NIH has shown lack of efficacy for the combination of the Eli Lilly/AbCellera anti-coronavirus antibody (bamlanivimab, LY-Co… Read More

    Are Medicinal Chemists Taking It Too Easy?

    I was speaking to a university audience the other day (over Zoom, of course) and as I often do I mentioned the studies that have looked at what kinds of reactions medicinal chemists actually use. The cliché is that we spend most of our time doing things like metal-catalyzed couplings and amide formation, and well… Read More

    The Vaccine Tightrope

    We’re getting closer to having to deal with a number of tricky issues around the first Emergency Use Authorizations (EUAs) for coronavirus vaccines. These have never quite come up in this way before, because (for one thing) EUAs for vaccines are relatively rare events, and (for another) we’ve never had so many simultaneous vaccine trial… Read More

    The Machines Rise a Bit More

    Here’s a new paper in Nature on computer-generated synthesis of natural products. More formally, you’d call it retrosynthesis, since the thought process in organic chemistry tends to work backwards when you have a particular target that you’re trying to make: “OK, this part could could be made from something like this. . .an… Read More

    The SOLIDARITY Data

    OK, we have some more to think about this morning. The large SOLIDARITY trial from the WHO has reported more interim data on its investigation into repurposed drugs for the coronavirus pandemic. And some of this we already knew, but some of it’s a real surprise. One drug reported on is hydroxychloroquine. This showed no… Read More

    Immunity and Re-Infection

    For months now, people have been watching closely to see if it’s possible to get re-infected with the coronavirus. It’s taken a while for the signal-to-noise to get better, but by now there’s no doubt that the answer is yes, it’s possible. We’ve just had the first of these in the US, a man in… Read More

    Another Vaccine Trial Halt

    The first advice is “Don’t panic”. You will have heard that last night J&J announced that their coronavirus vaccine dosing has been paused while they investigate an adverse event in the trial. And while you never like to hear that, considering the size of their effort, this sort of thing is likely to happen even… Read More

    Hard Data on Remdesivir, and on Hydroxychloroquine

    Let’s catch up with some things that (by this point) feel a bit like old news. But it’s important to do it, because (A) the big reason they feel that way is because of the bizarre world we’ve been living in the last few months, and (B) the pace of medical discovery is not set… Read More

    A Nobel for CRISPR

    The 2020 Chemistry Nobel has gone to Jennifer Doudna and Emmanuelle Charpentier for the discovery of CRISPR. An award in this area has been expected for some time – it’s obviously worthy – so the main thing people have been waiting for is to see when it would happen and who would be on it. Read More
