Degradation of intracellular TGF-β1 by PROTACs efficiently reverses M2 macrophage induced malignant pathological events

Chem Commun (Camb). 2020 Mar 5;56(19):2881-2884. doi: 10.1039/c9cc08391j.

Abstract

The first proteolysis targeting chimeras for the intracellular elimination of transforming growth factor-β1 (TGF-β1), which contributes to various diseases, are described. The appropriately designed DT-6 could efficiently degrade intracellular TGF-β1, and inhibit M2 macrophage induced epithelial to mesenchymal transition and invasive migration of cancer cells.
