Peptides

Peptides are amino acid polymers. They are generally much smaller than proteins and don’t have sufficient activity on their own – they generally represent a small portion of a full protein. They may also be signalling molecules that act through interaction with specific receptors, as in peptide hormones and cytokines.

    T cell cross-reactivity enables the immune system to recognize a large array of peptides. A new study shows that T cells can achieve cross-recognition by using the remarkable plasticity of peptides, through flipping the peptide out of the binding cleft.

    Encoded chemical libraries can be used to screen a vast array of compounds against a protein target to identify potent binders. A collection of articles in this issue discuss different methods to increase the chemical space sampled by encoded macrocycle libraries and the advantages that such libraries offer for discovering new drug leads.

    Certain drug targets have been deemed undruggable because of the difficulty in finding pharmacologically useful inhibitors. Now, two teams have developed exciting technologies for the creation of diverse collections of macrocyclic molecules and have demonstrated their usefulness for discovering macrocyclic inhibitors.
