Synthesis and evaluation of new designed multiple ligands directed towards both peroxisome proliferator-activated receptor-γ and angiotensin II type 1 receptor

Because of the complex biological networks, many pathologic disorders fail to be treated with a molecule directed towards a single target. Thus, combination therapies are often necessary, but they have many drawbacks. An alternative consists in building molecules intended to interact with multiple targets, called designed multiple ligands. We followed such a strategy in order to treat metabolic syndrome, by setting up molecules directed towards both type 1 angiotensin II (AT(1)) receptor and peroxisome proliferator-activated receptor-gamma (PPAR-gamma). For this purpose, many molecules were prepared by merging both pharmacophores following three different strategies. Their ability to activate PPAR-gamma and to block AT(1) receptors were evaluated in vitro. This strategy led to the preparation of many new PPAR-gamma activating and AT(1) blocking molecules. Among them, some exhibited both activities, highlighting the convenience of this approach. (C) 2018 Elsevier Masson SAS. All rights reserved.
