Cyclic peptides often exhibit low membrane permeability which can be significantly improved via amide-to-ester substitutions—as demonstrated by researchers from Tokyo Institute of Technology (Tokyo ...

Ring topology has captivated the imagination of chemists for many years. Of the various bioactive macrocycles known so far, cyclic peptides are of particular significance. In contrast to linear ...

Tsukuba, Japan—Cyclic molecules are used in a wide range of applications, including molecular sensing, because they can incorporate specific molecules of interest into their inner cavities.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The effectiveness of any drug molecule depends on how well it interacts with the internal environment inside our body. Its pharmacokinetic (PK) properties determine how successfully it escapes ...

A research team at CiQUS (University of Santiago de Compostela, Spain) has unveiled an innovative molecular approach that enables anticancer drugs to reach the nucleus of tumor cells, where they can ...
