Discovery of new SCH 39166 analogs as potent and selective dopamine D1 receptor antagonists
摘要:
A series of novel dopamine D-1 antagonists derived from functionalization of the D-ring of SCH 39166 were prepared. A number of these compounds displayed subnanomolar D-1 activity and more than 1000-fold selectivity over D-2. We found C-3 derivatization afforded compounds with superior overall pro. le in comparison to the C-2 and C-4 derivatization. A number of highly potent D-1 antagonists were discovered which have excellent selectivity over other dopamine receptors and improved PK pro. le compared to SCH 39166. (C) 2009 Elsevier Ltd.
