  Synthesis and evaluation of a potent, well-balanced EP 2 /EP 3 dual agonist

  摘要：

  A highly potent and well-balanced dual agonist for the EP2 and EP3 receptors is described. Optimization of the lead compound was accomplished in consideration of the relative agonist activity against each EP subtype receptor and the pharmacokinetic profile. As the result, 2-[(2-{(1R,2R)-2-[(1E,4S)-5-cyclopentyl-4-hydroxy-4-methyl-1-penten-1-yl]-5-oxocyclopentyl}eth-yl)thio]-1,3-thiazole-4-carboxylic acid (10) showed excellent potency (human EC50 EP2 = 1.1 nM, EP3 = 1.0 nM) with acceptable selectivity over the EP1 and EP4 subtypes (> 2000-fold). Further fine-tuning of compound 10 led to identification of ONO-8055 as a clinical candidate. ONO-8055 was effective at an extremely low dose (0.01 mg/kg, po, bid) in rats, and dose-dependently improved voiding dysfunction in a monkey model of underactive bladder (UAB). ONO-8055 is expected to be a novel and highly promising drug for UAB. (C) 2017 Elsevier Ltd. All rights reserved.

  A new strategy for the synthesis of 2,6-dideoxyamino sugars from non-sugar starting materials has been developed. The key reaction in this strategy is the acid-catalyzed intramolecular cyclization, by which a nitrogen functional group is introduced with simultaneous control of vicinal chiral centers. The synthesis of two kinds of 2,6-dideoxyamino sugars, D-vicenisamine and L-kedarosamine, by this strategy is described.
