New from our group: proline-rich peptides that target mitochondria & stay there! Tuning hydrophobicity and rigidity provided design rules for CPPs that enter cells and redistribute for long-term mitochondrial residency. Now out in ACS Chemical Biology: pubs.acs.org/doi/10.1021/...

We have multiple PhD and Postdoc positions open in my new group at Masaryk University. Are you an excellent and motivated candidate interested in organic and peptide synthesis and chemical biology? Get in touch! Start in January 2026. www.fialalab.com Appreciate sharing!

Excited to share our latest: we engineered the reactivity of a bacterial E1-like enzyme for ATP-driven modification of C termini. Our tool mimics the logic of peptide bond formation in biology for precision modification of proteins in vitro. 🧪https://rdcu.be/ewN7C

Selectively assembling collagen heterotrimers is a challenge. But not for us! Aminopropline-aspartate salt bridges drive the assembly of a hyperstable, a minimal-length, and a special blunt-ended collagen heterotrimer.

🚨 New preprint from our group! We report a photocatalytic, regiodivergent method to functionalize saturated N-heterocycles at the α- or β-position. The metal-free reaction runs in water with a flavin catalyst and gives rapid access to sought-after piperidines. Check it out here: 🔗 tin.al/DqxU

🚨 Happy to share a new preprint – our group’s first! 🔗 chemrxiv.org/engage/chemr... We report a novel synthetic method to access cyclic ethers from diketones, powered by simple borane catalysts. Thanks to the whole team for their excellent work!

According to tech firms, generative AI is going to cure cancer extremely soon. While that's false, the technology is transforming biomedical research. I talked to scientists and executives at universities, pharma companies, and research institutes to learn how: www.theatlantic.com/technology/a...

AI Executives Promise Cancer Cures. Here’s the Reality

The technology is genuinely useful for scientific discovery, but its applications are less dramatic than you might think.

Chiral spirocyclic oxetanes & azetidines synthesized by organocatalytic additions to strained nitroolefins—a practical route to medicinally relevant molecules. 🔗 pubs.acs.org/doi/full/10....

Enantioselective Conjugate Addition of Aldehydes to Oxetane- and Azetidine-Containing Nitroolefins: An Entry to Spirocyclic Pyrrolidines

Enantioselective amine-catalyzed conjugate additions of aldehydes to oxetane- and azetidine-containing nitroolefins afford γ-nitroaldehydes as key building blocks en route to spirocyclic oxetane/azetidine-pyrrolidines. The study provided insights into the stability and reactivity of these β,β-disubstituted nitroolefins and enabled the enantioselective synthesis of chiral oxetanes and azetidines in moderate-to-high yields and enantioselectivities. This approach expands synthetic access to medicinally relevant scaffolds and broadens the scope of enantioselective organocatalytic transformations.

Last year, we found that equipping a fibrosis-targeting collagen model peptide with a Texas Red fluorophore strongly affected the peptide’s folding behavior - so we looked more closely at the influence of fluorophores on triple helix formation and stability. Now out in ACIE: tinyurl.com/4sbhdv95

Fluorophores Nucleate and Stabilize Collagen Triple Helices – En Route to Better Diagnostic Tools for Fibrosis and Tissue Repair

Fluorescently labeled collagen model peptides (CMPs) are emerging as valuable diagnostic tools for fibrosis and tissue repair. We show that fluorophores markedly impact the folding behavior of CMPs a...
