Pentacyclic pyridoindolobenzob,ediazepines and thiazepines for treating CNS disorders

摘要

The present invention discloses pyridoinolobenzo[b,e]diazepine and thiazepine derivatives of Formula 1,; wherein X is NR¹⁰, S, S(O), or S(O)₂. Y is a single bond or no bond. A and B are independently (CH₂)_m and (CH₂)_n respectively; and the subscripts ‘m’ and ‘n’ independently vary from 1 to 4. R¹ to R⁹ are various electron donating, electron withdrawing, hydrophilic, or lipophilic groups selected to optimize the physicochemical and biological properties of compounds of Formula I.
