| Abstract: | Jenis demensia yang sering dialami oleh orang lanjut usia (lansia), salah
satunya yaitu penyakit Alzheimer. Penderita penyakit Alzheimer ditandai dengan
penurunan fungsi kognitif, memori, dan perubahan perilaku secara permanen.
Komponen aktif yang terkandung dalam daun sirih merah memiliki keterkaitan
dalam menghambat enzim butirilkolinesterase (BChE). BChE adalah salah satu
enzim yang berperan penting dalam penanganan penyakit Alzheimer yang
dikaitkan dengan patologis Alzheimer, yaitu hipotesis kolinergik. Penelitian ini
bertujuan menguji daya inhibisi senyawa aktif yang terkandung dalam daun sirih
merah terhadap aktivitas enzim BChE melalui pendekatan simulasi penambatan
molekuler. Metode yang digunakan pada penelitian melalui penggabungan metode
penapisan virtual dan penambatan molekuler sebagai tahapan awal pengembangan
daun sirih merah melalui penghambatan enzim BChE. Hasil yang telah diperoleh
pada penelitian ini, yaitu daya inhibisi terbaik dimiliki oleh 1,2,3,4,5,6,7-
heptazacycloicosane sebesar 0,4888 µM dan diperoleh energi bebas pengikatan
sebesar -8,6 kkal mol-1
. Residu yang terlibat pada pengikatan substrat oleh ligan uji
dengan enzim BChE, yaitu Tyr-332 dan Trp-82. Alzheimer’s disease is a type of dementia experienced by a significant portion of the world’s population. Alzheimer’s is characterized by a permanent decline in cognitive function, memory, and behavioral changes. The active components contained in red betel leaf are linked to inhibiting the butyrylcholinesterase (BChE) enzyme. According to the cholinergic hypothesis, BChE is an enzyme that may play an important role in the etiology and treatment of Alzheimer’s disease. The aim of the study was to test the inhibitory power of the active compound contained in red betel leaf against BChE through a molecular docking simulation approach. The method used in this research was a combination of virtual screening and molecular docking. The result obtained with the best inhibition were 1,2,3,4,5,6,7-heptazacycloicosane of 0,4888 µM and a binding free energy of -8,6 kkal mol-1. The amino acids involved in binding the substrate by the test ligand to BChE were Tyr-332 and Trp-82. |
