synthesized the linear analogues [D-Ala3]Dyn A(1-11)-NH2 (2) and [Ala3]Dyn A(1-11)-NH2 (3) and reported their biological activities. Analogues 2 and 3 displayed affinities for the central kappa opioid receptor (IC50 = 0.76 and 1.1 nM, respectively) similar to that of Dyn A(1-11)-NH2 (1) (IC50 = 0.58 nM) and greatly enhanced selectivities for kappa vs mu and kappa vs delta receptors (IC50 ratios of 350 and
