  Design, Synthesis, and Structure−Activity Relationships of Phthalimide-Phenylpiperazines:  A Novel Series of Potent and Selective α_1a-Adrenergic Receptor Antagonists

  摘要：

  Beginning from the screening hit and literature alpha(1)-adrenergic compounds, a hybridized basic skeleton A was proposed as the pharmacophore for potent and selective alpha(1a)-AR antagonists. Introduction of a hydroxy group to increase the flexibility afforded B which served as the screening model and resulted in the identification of the second-generation lead 1. Using the Topliss approach, a number of potent and selective alpha(1a)-AR antagonists were discovered. In all cases, binding affinity and selectivity at the alpha(1a)-AR of S-hydroxy enantiomers were higher than those of the R-hydroxy enantiomers. As compared to the des-hydroxy analogues, the S-hydroxy enantiomers had slightly lower binding affinity at alpha(1a)-AR but gained more than 2-fold selectivity for alpha(1a)-AR over alpha(1b)-AR, and 2- to 6-fold selectivity for alpha(1a)-AR over alpha(1d)-AR. They also had less cross activities against a panel of 25-35 peripheral and CNS receptors. The S-hydroxy enantiomers 23 and 24 (K-i = 0.29 nM, 0.33 nM; alpha(1b)/alpha(1a) >5690, >6060; alpha(1d)/alpha(1a) = 186, 158, respectively) were slightly less potent but much more selective at alpha(1a)-AR than tamsulosin (K-i = 0.13 nM, alpha(1d)/alpha(1a)= 14.8, alpha(1d)/alpha(1a) = 1.4). In the functional assay, the S-hydroxy enantiomers 20, 23, and 24 were less potent than tamsulosin in inhibiting contractions of rat prostate tissue but more selective in the inhibition of tissue contractions of rat prostate versus rat aorta. Compound 24 was selected as the development candidate for the treatment of BPH.

  improve stability, we replaced the pyrrole methylene linkage to the piperazine ring with ethylene, employed ethylene and dicarbonyl as linkers between the lactam and the pyrrole ring, placed electron-withdrawing groups on the pyrrole ring, and substituted acyclic amide for lactam. In addition, we replaced the pyrrole segment with other heterocycles including thiophene, furan, isoxazole, isoxazoline, and

  我们最近报道了一系列吡咯曼尼希碱在抑制大鼠条件性回避反应（CAR）方面具有口服活性。这些化合物对D2和5-HT1A受体均具有亲和力，并且有些是非致死肽的。这样的特征表明它们可能是潜在的抗精神病药，它们缺乏引起人锥体外系副作用和迟发性运动障碍的倾向。这些化合物之一，1-[[1-甲基-5-[[4- [2-（1-甲基乙氧基）苯基] -1-哌嗪基]甲基] -1H-吡咯-2-基]甲基] -2-选择哌啶酮（RWJ 25730，1）进行进一步开发，但发现在稀酸中不稳定。为了提高稳定性，我们用乙烯取代了哌嗪环上的吡咯亚甲基键，并使用乙烯和二羰基作为内酰胺和吡咯环之间的连接基，在吡咯环上放置吸电子基团，并用无环酰胺取代内酰胺。此外，我们用其他杂环取代了吡咯片段，包括噻吩，呋喃，异恶唑，异恶唑啉和吡啶。通常，用噻吩，呋喃，异恶唑啉或吡啶取代N-甲基吡咯片段可得到在CAR中与1等价的化合物，它们在稀酸中更稳定。
