    Natural Product Artifacts

    Like many organic chemists, I find natural products very interesting, since their structures are often things that I would never imagine making (and in some cases have trouble imagining how to make at all!) But there’s a feature of the literature in that area that not everyone appreciates: the fact that a reasonable number of… Read More

    Modifying Natural Products

    Here’s a thorough review of a topic that combines complex drug development issues with complex chemistry: trying to optimize the structures of natural products so that they can be more effective drugs. There are detailed looks at examples like the tetracyclines, the polyene macrolides, pactamycin, geldanamycin, and the thiostrepton-like pepti… Read More

    New Chemistry, Making New Things

    In a perverse way, I’m enjoying how modern organic synthesis is upsetting the classic undergraduate sort of test-question syntheses. You know – Grignards, ester condensations, oxidation and reduction of carbonyls, Wittigs, Sandmeyer reactions, Friedel-Crafts, good ol’ hammer-and-tongs bond formation. I had sophomore organic back i… Read More

    Proteasome Inhibitors, Refined

    The proteasome is quite the structure. It is the shredding unit of the cell, where no-longer-needed proteins go to be ripped down to their components for recycling, and it’s become a more and more important part of drug discovery over the years. For one thing, all this fashionable targeted protein degradation work is about sending… Read More

    Bacteria and Depression: Something to Test

    Microbiome, microbiome – you haven’t been able to turn around in this business the last few years without hitting some sort of story about the microbiome. It’s easy to roll your eyes and decide that it’s all hype, but that’s the thing: it really is important. It can’t be dismissed just because we don’t unde… Read More

    Artemisia Comes Through Again

    Here’s an unusual twist for you. Many readers will be familiar – to their regret, most likely – with the story of T*ring Pharmaceuticals (name redacted slightly in order to not defame a great scientist whose name was tacked on to this outfit for no reason other than advertising). Their first idea was to go… Read More

    A Slow, Slow Retraction

    Some readers may recall this post from 2015, which details problems with a natural product isolation paper in PLOS ONE. The compound, named Xinghaiamine A by the authors, was. . .well, let’s say extremely unlikely, and I think anyone who looks at the structure in that earlier post will agree. And that spans several levels… Read More

    Stop Ignoring the Sugars!

    This paper (from two groups at Yale’s chemistry department) addresses several important things that fall into the “important irritants” category in synthesis and molecular biology – or maybe that should be “irritatingly important”. We spend a lot of time thinking about proteins in terms of their primary sequence… Read More

    The Thoughts of George Whitesides, Part I

    A number of readers have mentioned this new paper by George Whitesides on organic synthesis. I can state as a fact that the first time I heard a joking reference to his attitude towards traditional synthetic organic chemistry was in the summer of 1983, so it’s not like he’s been keeping his thoughts bottled up.

    Scooped, I Suppose the Word Is

    Via Retraction Watch, here’s a situation that I don’t recall seeing before: a group at Foshan University in China published a paper in the journal Natural Product Research on the crystal structure of aspergicine. Here’s the original abstract in PubMed – their work prompted them to revise their previously published structure… Read More
