Abstract:
Tryptophan, commonly regarded as buried within the interior cores of proteins to maintain secondary structures, is now being recognized for its significant contributions to protein functionality. However, investigating functional tryptophan-involved interactions across the proteome and manipulating these interactions in live cells are considerable challenges. In this In Focus article, we summarize emerging advances in the field, describing innovative chemistries that leverage distinctive biochemical properties of the indole moiety for targeting and functionally manipulating tryptophan interactions.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
