  Design, synthesis and biological evaluation of pyridine-phenylpiperazines: A novel series of potent and selective α1a-adrenergic receptor antagonist

  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 the R-hydroxy enantiomers. As compared to the des-hydroxy analogues, the S-hydroxy enantiomers displayed comparable potency and better selectivity at alpha(1a)-AR. The S-hydroxy enantiomer 17 (K-i = 0.79 nM; alpha(1b)/alpha(1a) = 800; alpha(1d)/alpha(1a) = 104) was slightly less potent but much more selective at alpha(1a)-AR than tamsulosin (K-i = 0.13 nM, alpha(1b)/alpha(1a) = 15, alpha(1d)/alpha(1a) = 1.4). Compound 17 displayed higher selectivity in inhibiting rat prostate contraction over rat aorta contraction and also exhibited a higher degree of uroselectivity than tamsulosin in the anesthetized dog model.

  Nicotinamide ethers: novel inhibitors of calcium-independent phosphodiesterase and [3H]rolipram binding

  摘要：

  The synthesis and biological properties of a series of nicotinamide ethers are described. These compounds, structurally novel calcium-independent phosphodiesterase inhibitors, also inhibit the binding of [H-3]rolipram to rat brain membranes and reverse reserpine-induced hypothermia in the mouse. Several compounds exhibited potent in vivo activity comparable to the standard agent, rolipram.
