Very pleased to share the 'last' first-author paper from my postdoc with Prof. Christian Heinis at EPFL.
Now out in its final form in @angewandtechemie.bsky.social as a 'Very Important Paper' 🔥 (1/🧵) #chemsky

Bulk Measurement of Membrane Permeability for Random Cyclic Peptides in Living Cells to Guide Drug Development

Some cyclic peptides can cross membranes, which is highly attractive for drug development, but it remains difficult to accurately predict membrane permeability or to test it experimentally for large ...

My colleagues at Novo Nordisk have developed long-acting variants of PYY which, when combined with semaglutide, show promise in improving obesity and blood glucose regulation in preclinical models without muscle loss. Read more here: www.science.org/doi/10.1126/...

Variant screening of PYY3–36 leads to potent long-acting PYY analogs with superior Y2 receptor selectivity

A Y2 receptor–selective and long-acting PYY derivative improves weight loss and glucose metabolism in rodents in combination with a GLP-1 agonist.

Exciting paper by colleagues at Novo Nordisk: a scalable method for C-terminal α-amidation of peptides & proteins. The protocol is highly relevant for the production of amidated peptide drugs such as amylins! #PeptideScience

Photochemically-enabled, post-translational production of C-terminal amides - Nature Communications

C-terminal α-amidated peptides are attractive therapeutic targets, but preparative methods to access amidated pharmaceuticals are limited both on lab and manufacturing-scale. Here, the authors report ...

Another great paper from #NovoNordisk on how housing mice near vs below thermoneutrality affects drug-induced weight loss because thermal stress greatly increases energy expenditure. Key to better evaluating data in the quickly growing field of obesity research! www.sciencedirect.com/science/arti...

Housing mice near vs. below thermoneutrality affects drug-induced weight loss but does not improve prediction of efficacy in humans

Evaluation of weight loss drugs is usually performed in diet-induced obese mice housed at ∼22°C. This is a cold stress that increases energy expenditu…

To tackle the challenge of proper glycaemic control for people on insulin therapy, my colleagues at Novo Nordisk have engineered a glucose-responsive insulin, which shows reduced activity at low glucose levels, thereby mitigating the risk of hypoglycemia. www.nature.com/articles/s41...

NNC2215 is an insulin conjugate that can reversibly adjust its bioactivity in response to a diabetes-relevant glucose range in vivo.
