摘要:
To deter-mine if the indolic nitrogen atom is required for the binding of N-1-benzyltryptamines at h5-HT6 serotonin receptors, several isotryptamines and indene analogs were examined. The affinity of 3-benzyl-N-1-(N,N-dimethylaminoethyl)indole (5, K-i = 32 nM) and 1-benzyl-3-(N,N-dimethylaminoethyl)indene (11, K-i = 3 nM) indicates that the indolic nitrogen atom is not essential for binding.
