摘要:
The synthesis of several bioisosteric analogs based on the 3-OH-N'-phenylpiperazine dopamine D-2 agonist template (i.e., 4) is described. The indolone (5) and 2-CF3-benzimidazole (13) were observed to have: excellent affinity for the D-2 receptor. Several Dq selective compounds were also identified. Molecular modeling studies and a putative bioactive conformation are discussed. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
