First thiol smell of the new year. And it's not even a particularly noxious one! #chemsky

We're officially back for the new year. The built-up freezer ice looks so neat it's almost a shame to de-ice it all.

Check out some of the great work being done by our collaborators in the Schmeing lab in Biochemistry!
In partnership with the Canadian Light Source's beamline, they're examining the structure and workings of itaconate-degrading enzymes.

NEW PREPRINT:

An extensive structure-activity relationship investigation of pantetheinamides and their ability to inhibit Salmonella typhimurium.

We investigate the mechanisms of action of these compounds and their use with in vivo mouse models.

Update: purified it anyways. Fraction looks reasonably pure. Now let's see the activity tests. #chemsky

The Auclair Lab welcomes two new members!

Maya Gaylor, co-supervised by Prof. Lupien in Microbiology and Immunology, will be working on our antimicrobial projects.

Dr. Alana Rangaswamy is a recent graduate from the Keillor lab @uottawa.ca and will focus on enzyme and depolymerization efforts.

Admin got up yesterday at 7 in the morning to perform a transformation that probably didn't work. One (1) colony on the plates. This is the #chembiosky life.

Fun fact: we scheduled our lab cleanup day a few weeks ago, and the second we finished up, we got a notification that we were having a safety inspection the very next Monday.

Talk about good timing #chemsky

‼️NEW PAPER ALERT

In Antimicrobial Agents and Chemotherapy, we replace an enzyme-vulnerable amide bond with a thiazole to produce potent antiplasmodial and antimalarial pantothenamide mimics. A collaboration between the Auclair lab @mcgill.ca and the Saliba lab at ANU.

Another day, another paper 😌

- Our pantothenamide mimics avoid degradation by pantetheinases thanks to the bond substitution

- Sub-micromolar antiplasmodial activity in vitro

- Excellent selectivity for plasmodial enzymes vs. human enzymes

- Computational analysis included to gain insight into SARs

Key notes:

- Made possible by Annica Chu, Dr. Mina Nekouei, Dr. Blue Lan, and Dr. Alexandre Pierret of the Auclair lab, in collaboration with Xiangning Liu from the group of Prof. Kevin J. Saliba

- These molecules follow the parasite CoA pathway and become potent, low-cytotoxicity antimetabolites
