[EN] N-HETEROCYCLYL SUBSTITUTED 2-CYANO-3-(NAPHTHALEN-2-YL)ACRYLAMIDE DERIVATIVES AS FLUOROPHORS FOR DETECTION OF AMYLOID AND AMYLOID-LIKE PROTEINS FOR DIAGNOSIS OF NEURODEGENERATIVE DISORDERS [FR] DÉRIVÉS DE 2-CYANO-3-(NAPHTHALÈN-2-YL)ACRYLAMIDE SUBSTITUÉS EN N-HÉTÉROCYCLYLE EN TANT QUE FLUOROPHORES POUR LA DÉTECTION DE PROTÉINES AMYLOÏDES OU DE TYPE AMYLOÏDE POUR LE DIAGNOSTIC DE TROUBLES NEURODÉGÉNÉRATIFS
摘要:
Provided herein is the design and synthesis of novel molecular rotor fluorophores of formula I useful for detection of amyloid or amyloid like proteins. The fluorophores are designed to exhibit enhanced fluorescence emission upon associating with amyloid or amyloid like proteins as compared to unbound compound. Also disclosed herein are the compounds for use in methods for diagnosis and treatment of diseases associated with an amyloid or amyloid like proteins, such as e.g. Alzheimer's disease or traumatic brain injury (TBI), Parkinson's disease, vascular dementia, amyotrophic lateral sclerosis, Down syndrome, traumatic brain injury, chronic traumatic encephalopathy, schizophrenia or depression. Exemplary compounds are e.g. N-heterocyclyl substituted 2-cyano-3- (naphthalen-2-yl)acrylamide derivatives, such as e.g. (E)-2-cyano- N-(2-(2-hydroxy)ethoxy)ethyl)-3-(6-(pyrrolidin-1-yl)naphthalen-2-yl) acrylamide (example 1): Experimental data on in-vitro binding studies with amyloid beta is provided.
