Abstract: This disclosure relates to new tetracyclic compounds that may be used to modulate a histamine receptor in an individual. The compounds in one embodiment are tetracyclic [4,3-b]indoles. Pharmaceutical compositions comprising the compounds are also provided, as are methods of using the compounds in a variety of therapeutic applications, including the treatment of a cognitive disorder, psychotic disorder, neurotransmitter-mediated disorder and/or a neuronal disorder.

Abstract: The present invention relates to combination therapies and methods for treating, preventing and/or delaying the onset and/or development of schizophrenia, wherein the combination therapies comprise a hydrogenated pyrido[4,3-b]indole or a pharmaceutically acceptable salt thereof, such as dimebon, and an antipsychotic.

Abstract: A means for improving cognitive functions and memory based on hydrogenated pyrido (4,3-b) indoles (variants), a pharmacological means based thereon and a method for the use thereof relate to the use of chemical compounds in the field of medicine and may be used to extend the arsenal of means which can be utilized for substantial enhancement of memory and activation of the learning process, for the treatment of impaired cognitive functions and memory in the elderly and in mild cognitive impairment, in brain trauma, in chronic cerebrovascular insufficiency, in hypoxic encephalopathies, resulting from chronic alcoholism and in delayed development in children. Said task is resolved by the use of hydrogenated pyrido ([4, 3-b]) indoles of formula (1) or formula (2) as means for improving cognitive functions and memory.
