The piperazine family can, perhaps, be a fertile soil to explore.

Patent US6172229

Only if you are interested in neuroleptics...    Or am I missing something?

Considering the dopamine/noradrealine releasing effect of 1-benzylpiperazine and the wierd serotonergic effect of 1-(3-trifluorophenyl)piperazine, I´m pretty sure there might be a few hidden treasures within the piperazine family.
Also, in the patent above, on page 2, there is also mentioned something about a japanese patent regarding m-trifluoromethylphenyl benzyl piperazines having analgetic and tranqualizing properties. Might come handy when the voices in the head becomes too loud and annoying.  

Hey Barium, would you be interested in having that text typed/posted?  don't want to do it if nobody's interested.
