Abstract: The present application relates to indole compounds of general formula I, to processes for their preparation, to compositions comprising them and to their use in activation of a serotonin receptors in a cell, as well as to treating diseases, disorders or conditions by activation of a serotonin receptors in a cell. The diseases, disorders or conditions include, for example, psychosis, mental illnesses and CNS disorders, Formula I (I) wherein Q is selected from (Q1), (Q2), (Q2?), (Q3), (Q4) and (Q5).

Abstract: The present application relates to indole derivatives of general Formula I, to processes for their preparation, to compositions comprising them and to their use in activation of a serotonin receptors in a cell, as well as to treating diseases, disorders or conditions by activation of a serotonin receptors in a cell. The diseases, disorders or conditions include, for example, psychosis, mental illnesses and CNS disorders. Formula I wherein Q is selected from (Q1), (Q2), (Q2?), (Q3), (Q4) and (Q5). The treatment methods of the application have a reduced risk for or association with serotonin syndrome.

Abstract: The present application relates to 3-cyclic amine-indole derivatives of general Formula (I), to processes for their preparation, to compositions comprising them and to their use in activation of a serotonin receptor in a cell, and treating diseases, disorders or conditions treatable by activation of a serotonin receptor in a cell. The diseases, disorders or conditions include, for example, psychosis and mental illness.

Abstract: Compounds of Formula I are useful for the treatment of anxiety disorders such as generalized anxiety disorder (GAD), panic attack, post traumatic stress disorder (PTSD), obsessive compulsive disorder (OCD) and social phobias. wherein: A is chosen from: aryl or heteroaryl, A being optionally substituted with up to 5 independently-selected groups R8; R1 is chosen from: alkyl or haloalkyl; R2 is chosen from: H, C(O)R6, C(O)OR6, SO2R6 or C(O)NR6R7; R3, R4 and R5 are independently chosen from: H or alkyl; R6 and R7 are independently chosen from: H or alkyl; and R8 is chosen from: OH, CN, halo, alkyl, alkoxy, haloalkyl, haloalkoxy, C(O)R6, C(O)OR6, SO2R6 or C(O)NR6R7.
