The piperazine family can, perhaps, be a fertile soil to explore.
Patent US6172229 (http://l2.espacenet.com/dips/viewer?PN=US6172229&CY=gb&LG=en&DB=EPD)
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.
