New generation dopaminergic agents. 2. Discovery of 3-OH-phenoxyethylamine and 3-OH-N1-phenylpiperazine dopaminergic templates
摘要:
Described in this report is a systematic study which led to the identification of two new dopamine D-2 partial agonists (5 and 17). Phenols 5 and 17 represent prototypes of two new classes of D-2 partial agonists as well as templates for the future design of novel dopaminergic agents. (C) 1998 Elsevier Science Ltd.
