BMY 7378 (free base) is a selective antagonist of α1D-adrenoceptor (α1D-AR). BMY 7378 (free base) binds to membranes expressing the cloned rat α1D-AR with a >100-fold higher affinity (Ki=2 nM) than binding to either the cloned rat α1A-AR (Ki=800 nM) or the hamster α1B-AR (Ki=600 nM). BMY 7378 (free base) is a 5-HT1A receptor partial agonist[1][2].

ChEBI:8-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-8-azaspiro[4.5]decane-7,9-dione is a member of piperazines.
