  Pyrrolidine-3-carboxylic Acids as Endothelin Antagonists. 4. Side Chain Conformational Restriction Leads to ET_B Selectivity

  摘要：

  When the dialkylacetamide side chain of the ETA-selective antagonist ABT-627 is replaced with a 2,6-dialkylacetanilide, the resultant analogues show a complete reversal of receptor selectivity, preferring ETB over ETA. By optimizing the aniline substitution pattern, as well as the alkoxy group on the 2-aryl substituent, it is possible to prepare antagonists with subnanomolar affinity for ETB and with selectivities in excess of 4000-fold. A number of these compounds also show promising pharmacokinetic profiles; a useful balance of properties is found in A-192621 (38). Pharmacology studies with A-192621 serve to reveal the role of the ETB receptor in modulating blood pressure; the observed hypertensive response to persistent ETB blockade is consistent with previous postulates and indicates that ETB-selective antagonists may not be suitable as agents for long-term systemic therapy.
