We have discovered two substituted 4-aminopiperidine compounds having high in vitro affinity and selectivity for the human dopamine D1 receptor. Both compounds, 3-ethoxy-N-methyl-N-[1-(phenylmethyl)-4-piperidinyl]-2-pyridinylamine (U-99363E), and its 3-isopropoxy analog (U-101958), were found through a routine receptor binding screen. The determined affinities
Substituted aminopiperidines as selective and potent D4-dopamine receptor antagonists.

This study was conducted to determine the expression of dopamine D(2)-like receptors in opossum kidney (OK) cells and to examine the potential role of these receptors in mitogenesis. First, the presence of D(2)-like receptor binding sites in OK cell membranes
