TCS 1205 is an organic chemical compound.

It is a benzodiazepine site agonist selective for certain sub-units.

TCS 1205 acts at the benzodiazepine binding site, it is selective for the α1 and α2 subunits of the GABAA receptor.

[1] In vivo, it has anxiolytic effects but no sedative effects.

[2][3] Despite acting at the benzodiazepine receptor, it does not contain the benzodiazepine structure, it could therefore be classed as a nonbenzodiazepine.
