Abstract: | The number of drugs used for the treatment of Alzheimer‟s disease is quite limited.
These drugs (e.g., cholinesterase inhibitors and N-methyl-D-aspartate receptor
antagonist) provide symptomatic treatment rather than a total cure. Therefore, there
has been great scientific interest worldwide for the design and development of novel
drug candidates for the treatment of this neurodegenerative disease.
Previous studies indicated that the urolithin (hydroxy substituted benzo[c]chromen -
6-one) scaffold can be employed to design molecules promising to act as multi target
ligands against Alzheimer‟s disease. Within the scope of this research study, we have
aimed to synthesis 3-subsitiuted benzo[c]chromen-6-one, and 3-subsistuted 7,8,9,10-
tetrahydrobenzo[c]chromen-6-one derivatives connected to an amide function with a
spacer. The enzyme inhibitor activities (i.e., acetylcholinesterase,
butyrylcholinesterase, and monoamine oxidase B) concomitant to antioxidant and
amyloid beta aggregation inhibitor characteristics of the title molecules have been
planned to be screened.
The results pointed out several drug candidate molecules possessing multi target
ligand feature in terms of inhibiting the aforementioned enzymes with anti-oxidant
properties in ORAC assay conditions. Moreover, the computer aided docking studies
revealed out the predicted binding modes of the most active compounds displaying
the possible interactions with the receptors.
Keywords: Urolithin derivatives, Cholinesterase inhibitors, Monoamine oxidase B,
Antioxidant. ÖZ:Alzheimer hastalığının tedavisi için kullanılan ilaç sayısı oldukça sınırlıdır. Bu ilaçlar
(kolinesteraz inhibitörleri ve N-metil-D-aspartat reseptörü antagonistleri) tam bir
tedavi yerine semptomatik tedavi sağlar. Bu nedenle, bu nörodejeneratif hastalığın
tedavisinde kullanılabilecek orijinal ilaç adayı bileĢiklerin keĢfi için tüm dünyada
büyük bir bilimsel merak söz konusudur.
Önceki çalıĢmalarda ürolitin olarak tanımlanan hidroksi sübstitüe benzo[c] kromen 6-on türevi bileĢiklerin Alzheimer Hastalığına karĢı çoklu hedefe etki edebilecek
bileĢiklerin tasarımında kullanılabileceği gösterilmiĢtir. Bu araĢtırma çalıĢması
kapsamında, amid grubununa bir ara grup ile bağlanmıĢ 3-sübstitüe benzo [c]
kromen-6-on ve 3-sübstitüe 7,8,9,10- tetrahidrobenzo [c] kromen-6-on türevi
bileĢikleri sentez etmeyi amaçladık. Bu bileĢiklerin enzim inhibitör aktiviteleri
(asetilkolinesteraz, butirilkolinesteraz ve monoamin oksidaz B), antioksidan ve
amiloid beta agregasyon inhibitörü özelliklerini de incelemeyi planladık.
Sonuçlar, birkaç ilaç adayı molekülün çoklu hedefe yönelik ligand özelliği ile
yukarıdakı enzimleri inhibe ettiğini ve ORAC test koĢullarında antioksidan özelliğe
sahip olduğunu gösterdi. Ayrıca bilgisayar destekli dokloma çalıĢmalarında en aktif
bileĢiklerin reseptörlerle olası etkileĢimleri gösterilmiĢ ve öngörülen bağlanma
durumları ortaya konmuĢtur.
