Development of a new class of benzoylpyrrole-based PPARα/γ activators
摘要:
Starting with a subtle blood glucose-lowering effect of a TGF-beta inhibitor, we designed and synthesized a series of benzoylpyrrole-based carboxylic acids as PPARs activators. Among these compounds, 10sNa exhibited favorable blood glucose-lowering effect without body weight gain. We assume that the beneficial effect of 10sNa is attributed to not only its compound PPAR alpha agonistic activity but also its PPAR gamma partial agonistic activity. (C) 2010 Elsevier Ltd.

A ruthenium‐catalyzed carbonylative CH bond arylation process for the three‐component synthesis of complex aryl–(hetero)arylketones in an aqueous solution has been developed. By exploiting the ortho‐activating effect of nitrogen‐containing directing groups, a regioselective, successive twofold C(sp2)C(sp2) bond formation has been achieved. This straightforward catalytic process provides access to
Pyrrole and its derivatives react smoothly with acid chlorides and sulfonyl chlorides in the presence of zinc metal in toluene at ambient temperature to afford the corresponding 2-acetyl and 2-sulfonyl pyrrole derivatives in high yields with high regioselectivity.
