Phenoxyethylamine derivatives, for preparing the same and composition
A series of indoline and indole derivatives were designed, synthesized, and evaluated as selective α1A-adrenergic receptor (α1A-AR) antagonists for the treatment of benign prostatic hyperplasia (BPH). In this study, two highly selective and potent α1A-AR antagonists, compounds (R)-14r (IC50 = 2.7 nM, α1B/α1A = 640.1, α1D/α1A = 408.2) and (R)-23l (IC50 = 1.9 nM, α1B/α1A = 1506, α1D/α1A = 249.6), which

To find a novel α-blocker with high α-blocking selectivity against dopamine D2-receptor affinity, we performed structural modification of the alkylene chains and the substituents on two benzene rings of 2-alkoxy-5-[(phenoxyalkylamino)alkyl]benzenesulfonamide derivatives. The modification of the alkylene chain between the amino moiety in the center of the molecule and the benzene ring (ring A) was found to be the most significant. 5-[2-[[2-(5-Fluoro-2-methoxyphenoxy)ethyl]amino]propyl]-2-methoxybenzenesulfonamide (II-4), which possesses 1-methylethyl as the alkylene chain, exhibited high α-blocking selectivity as well as potent α-blocking activity.
