  6-Methoxy-7-benzofuranoxy and 6-Methoxy-7-indolyloxy Analogues of 2-[2-(2,6-Dimethoxyphenoxy)ethyl]aminomethyl-1,4-benzodioxane (WB4101):1 Discovery of a Potent and Selective α_1D-Adrenoceptor Antagonist

  摘要：

  Previous results have shown that replacement of one of the two o-methoxy groups at the phenoxy residue of the potent, but not subtype-selective, alpha(1)-AR antagonist (S)-WB4101 [(S)-1] by phenyl, or by ortho,meta-fused cyclo-hexane, or especially by ortho,meta-fused benzene preferentially elicits alpha(1D)-AR antagonist affinity. Such observations inspired the design of four new analogues of 1 bearing, in lieu of the 2,6-dimethoxyphenoxy residue, a 6-methoxy-substituted 7-benzofuranoxy or 7-indolyloxy group or, alternatively, their corresponding 2,3-dihydro form. Of these new compounds, which maintain, rigidified, the characteristic ortho hetero-disubstituted phenoxy substructure of 1, the S enantiomer of the dihydrobenzofuranoxy derivative exhibited the highest alpha(1D)-AR antagonist affinity (pA(2) 9.58) with significant alpha(1D)/alpha(1A) and alpha(1D)/alpha(1B) selectivity. In addition, compared both to alpha(1D)-AR antagonists structurally related to 1 and to the well-known alpha(1D)-AR antagonist BMY7378, this derivative had modest 5-HT1A affinity and neutral alpha(1)-AR antagonist behavior.
