When Binding Is Not Enough: Solving the Delivery Problem in Antisense PNA Research

Antisense technologies have become indispensable tools in modern molecular biology and therapeutic research. Modalities such as antisense oligonucleotides (ASOs), small interfering RNA (siRNA), and peptide nucleic acids (PNAs) allow researchers to modulate gene expression with high sequence specificity. Over the past two decades, advances in ta…

The Hidden Signals: Leptin, Ghrelin, and the Battle for Balance

This blog explores the critical roles of leptin and ghrelin — two key hormones that regulate appetite and energy balance — and how their dysfunction contributes to obesity. Leptin, produced by fat cells, signals satiety, while ghrelin, secreted by the stomach, stimulates hunger. In individuals with obesity, leptin resistance prevents the brain …

How Permeation Enhancers Enable Oral Peptide Drugs: A Molecular View from SNAC and Semaglutide

For decades, oral delivery of peptide drugs has been one of the most persistent challenges in pharmaceutical science. Peptides are intrinsically ill-suited for oral administration: they are rapidly degraded by proteases and exhibit extremely low passive permeability across epithelial membranes. While injectable formulations have enabled the clin…

Next-Generation PROTACs: Peptide Strategies for Advanced Therapeutics

Proteolysis-targeting chimeras (PROTACs) have emerged as a transformative modality in drug discovery by leveraging the ubiquitin–proteasome system to selectively degrade disease-associated proteins. While small-molecule PROTACs have demonstrated success, their reliance on well-defined ligandable pockets leaves many clinically relevant proteins …
