Abstract

Thumbnail image of graphical abstract

The inside cover picture shows the X-ray-determined binding of an α-ethoxy-phenyl-propionic acid-derived dual PPARα/γ agonist in complex with PPARα (yellow) and PPARγ (blue). The high α-selectivity of this phenylthiazole (IC50 γ/α = 37; EC50 γ/α = 7) can be rationalized mainly by a single residue difference, Cys 275 (α) vs. Gly 284 (γ), leading to three additional interactions with the terminal p-Cl-Ph group. In addition, its binding site is highlighted in a surface representation of the PPARα protein. For more details, see the Communication by U. Grether et al. on p. 951 ff.
