Design, parallel synthesis and SAR of novel urotensin II receptor agonists
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 5 mg of starting mater
