Title: Design, parallel synthesis and SAR of novel urotensin II receptor agonists.
Authors: Lehmann F, Lake L, Currier EA, Olsson R, Hacksell U, Luthman K.
Abstract: A 30-membered library of amides based on the potent urotensin II (UII) receptor agonist FL104, has been synthesized from ten different carboxylic acids and three amines. A synthetic protocol producing the amides in 47-98% yield has been developed in which the purification involved only extractions and in a few cases filtration through an ion-exchange resin. It was found that 5mg of starting material was enough to obtain reproducible results and excellent purities. Thus, the procedure is estimated to be transferable to fully automated systems. The synthesized compounds were evaluated for their UII receptor agonistic activities using a cell-based assay (R-SAT). The most active compounds were the 4-trifluoromethylcinnamic amides of 1-(4-chlorophenyl)-3-dimethylamino-propylamine and 1-(2-naphthyl)-3-dimethylamino-propylamine, both showed EC(50) values of 130 nM.
