Zusammenfassung:This invention relates to benzodiazepine derivatives, compositions comprising therapeutically effective amounts of those derivatives and methods of using those derivatives or compositions in treating cognitive impairment associated with CNS disorders. It also relates to the use of an α5-containing GABAA receptor agonist (e.g., an α5-containing GABAA receptor positive allosteric modulator) in treating cognitive impairment associated with CNS disorders in a subject in need or at risk thereof, including age-related cognitive impairment, Mild Cognitive Impairment (MCI), amnestic MCI, Age-Associated Memory Impairment, Age Related Cognitive Decline, dementia, Alzheimer's Disease(AD), prodromal AD, PTSD, schizophrenia, bipolar disorder, ALS, cancer-therapy-related cognitive impairment, mental retardation, Parkinson's disease, autism spectrum disorders, fragile X disorder, Rett syndrome, compulsive behavior, and substance addiction. It also relates to the use of an α5-containing GABAA receptor agonist (e.g., an α5-containing GABAA receptor positive allosteric modulator) in treating brain cancers (including brain tumors, e.g., medulloblastomas), and cognitive impairment associated therewith. Esta invención se refiere a derivados de benzodiazepina, a composiciones que comprenden cantidades terapéuticamente eficaces de esos derivados y a métodos para usar esos derivados o composiciones en el tratamiento del deterioro cognitivo asociado con trastornos del SNC. También se relaciona con el uso de un agonista del receptor GABAA que contiene a5 (por ejemplo, un modulador alostérico positivo del receptor GABAA que contiene a5) en el tratamiento del deterioro cognitivo asociado con trastornos del SNC en un sujeto que lo necesite o esté en riesgo, incluyendo deterioro cognitivo relacionado con la edad, deterioro cognitivo leve (DCL), DCL amnésico, deterioro de la memoria asociado a la edad, declive cognitivo relacionado con la edad, demencia, enfermedad de Alzheimer (EA), EA prodrómica, TEPT, esquizofrenia, trastorno bipolar, ELA, deterioro cognitivo relacionado con la terapia del cáncer, retraso mental, enfermedad de Parkinson, trastornos del espectro autista, trastorno X frágil, síndrome de Rett, comportamiento compulsivo y adicción a sustancias. También se refiere al uso de un agonista del receptor GABAA que contiene a5 (por ejemplo, un modulador alostérico positivo del receptor GABAA que contiene a5) en el tratamiento de cánceres cerebrales (incluidos tumores cerebra
