Klebanoff and Walz publish another TCR structure which explains how TCR binding to p/HLA triggers intracellular signaling. CryoEM in native environment reveals a 'jack-in-the-box' mechanism - super super cool www.nature.com/articles/s41...

holy wow - what school is this

William Withering popularized the use of foxglove which ultimately led to today's FDA approved cardiac glycoside digoxin. His degrees are listed as "MD, FRS, etc. etc." 😂

Well shoot. Mice shouldnt get tattoos then.

1. This is really cool, great idea 2. Who came up with these reaction choices, my sophomore organic text? #chemchat www.organicdivision.org/2025-organic...

Actually I'd love to get a count on here of who's actually done particular reactions. I bet there are loads of odd ones chemsky has drawn on when needed

Has anyone here ever, even once, done a Wulff-Kishner reaction? #chemchat

What Do Oral Drugs Really Look Like? Dose Regimen, Pharmacokinetics, and Safety of Recently Approved Small-Molecule Oral Drugs

The @ragoninstitute.bsky.social is launching a new faculty search for a computational immunologist! Applications are open now and reviewed on a rolling basis. Please share broadly with your networks! #immunosky www.nature.com/naturecareer...

Just mapped out all 2025 FDA small-molecule approvals — and the trends are striking. Oncology dominates again, but a few companies really stood out: • Bayer: 2 approvals • Boehringer Ingelheim: 2 • Novartis: 2 • Sanofi: 2 (Poster below 👇) #FDA #DrugDiscovery #Biotech #Oncology

I started making a poster for my Med Chem undergrads because I want them to be able to immediately identify common drug classes by structure. Which others would you add to these?

Novo Nordisk’s recent clinical setback with GLP-1s in Alzheimer’s highlights a broader truth: metabolic peptides aren’t automatically neurotherapeutics. The next real opportunity lies in brain-penetrant, neuroprotective, glycosylated PACAP-derived peptides. www.mdpi.com/1422-0067/22...

quite interesting indeed. GLP-1s are everywhere and ketohexokinase inhibitors might treat alcoholism.

How old are you??? just kidding. reposting for visibility.

Fun fact: perfluorhexyloctane is approved by the FDA as an ophthalmic solution to treat symptoms of dry eye disease. Solubility = 0 Half-life = forever

2025 FDA approvals (as of Dec 1): 38 novel drugs • 28 small molecules (74%) 67% of those are chiral — highest % in FDA history (1951–2025) After years of biologics rising, 2025 is the year of the comeback for single-enantiomer drugs. #FDAApprovals #Chirality #DrugDiscovery

The 2026 Chemistry Faculty Jobs List has 330 tenure-track positions and 47 teaching-only positions: docs.google.com/spreadsheets... #facultychemjobs #chemsky #chemchat ⚗️🧪

The chemical information encoded by a molecule influences parameters like solubility, bioavailability, and even off target effects. Since the 1950s, the information density of drugs has increased. Over the next few weeks we will dive into these trends.

The chemotypes within FDA approvals so far this year are quite diverse. Most of the 2025 small molecule approvals are chiral with four covalent electrophiles.

Wow 28/38 of the drugs approved so far this year are small molecules (30 small molecule structures including combinations). Lots of covalent drugs, too. Very exciting.

whoa

A few py2Dmol updates 🧬 py2dmol.solab.org Integration with AlphaFoldDB (will auto fetch results). Drag and drop results from AF3-server or ColabFold for interactive experience! (1/4)

this speaks to my soul

week holiday sales huh?

handsome

keep an eye on your brother

Generic drug manufacturing is going to be difficult to (re)establish in the US:

handsome boy

teaching med chem today

i love this - silicon for sp3 and boron for sp2 all the way

First author Valentin Bruttel has responded over at X. Here's my quick take: a) Mutation rates are irrelevant; I show there aren't any mutations at all, so this part of Bruttel et al, which is also nonsense, is irrelevant. b–e) Four things that are irrelevant to analysis in his paper.

let's go

Interesting piece in The Lancet www.thelancet.com/action/showP...

If humans had descended from carnivores we wouldn't have ended up with the pharmacopoeia we have today.

do any of my chemist friends on here know where i can get a new or used ozonolyzer?

Anyone from the University of Montreal here? Please DM. Please RT.

weather

if anyone has previously used the MISTIC2 web server to do covariation analysis (it's been down for a long time) I wrote my own code to do the same thing. it'll be on gihub eventually but for now you can DM me if you want it. rp if you want
