摘要

The Alzheimer's disease(AD)is a neurodegenerative illness,which affects millions of people worldwide.AD is characterized by progressive dementia of memory,intellectual,speech and brain disturbances.In our previous work we proposed a new approach to the creation of inhibitors of y-secretase by synthesizing new derivatives of the 7,8-dimefhoxy-l-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine containing dipeptides /N-[N-(3,4-dichlorophenyl)-D,L-Ala]-L-Phe-OH,N-[N-(3,4-dichlorophenyl)-D,L-Ala]-L-Val-OH,N-[N-(3,4-dichlorophenyl)-D,L-Ala]-L-Leu-OH,N-[N-(3,4-dichlorophenyl)-D,L-Ala]-Gly-OH/.By the synthesis of these compounds we intend to combine two important pharmacological effects for the treatment of the disease:inhibition of the y-secretase by the peptide fragment and increasing of the level of neuromediators dopamine,noradrenaline and serotonine in brain by inhibition of their uptake in neurons by the benzazepine heterocycle.We proved the later effect in our earlier publication [2].In the present work,we synthesized optically active derivative of the benzazepine containing N-[N-(3,4-dichlorophenyl)-D,L-Ala]-L-Phe-OH.We intended to research the action of the stereo chemical factor on the inhibition of the y-secretase of these two isomers.
