Abstract

Nine resorcinol derivatives were evaluated for their ability to inhibit yeast α‐glucosidase using the in vitro method. Three molecular docking programs (Autodock Vina, Autodock4 and DockThor) were employed to determine the binding energies. The results showed that two resorcinol derivatives possessing butanoyl (1) and butyl (9) groups demonstrated good inhibitory activity against α‐glucosidase, with IC50 values of 75.9 and 33.3 µM respectively, compared with other derivatives (2–8) and acarbose (IC50 = 832.8 µM). Furthermore, molecular docking indicated that compounds 1 and 9 had better binding affinities than acarbose and the native ligand. Both compounds showed similar interactions with Asp349 and Glu408, which were associated with acarbose and the native ligand. Moreover, molecular dynamics analysis indicated that compound 9 exhibited greater stability than compound 1 when complexed with α‐glucosidase. Therefore, compound 9 has the potential for further studies, both in vitro and in vivo, to evaluate its toxicity, side effects and efficacy.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh fermentasi dengan nanas dan jenis metode ekstraksi terhadap Kadar Total Fenol dalam bubuk minuman mirip kopi yang terbuat dari biji kurma (Phoenix dactylifera L.). Biji kurma terlebih dahulu difermentasi menggunakan nanas, kemudian dikeringkan dalam oven, disangrai, dan digiling menjadi bubuk. Proses ekstraksi dilakukan dengan tiga metode: dekokta, maserasi etanol, dan seduh dingin. Kadar total fenol diukur menggunakan metode Folin-Ciocalteu dan hasilnya dinyatakan dalam mg GAE/g. Hasil penelitian menunjukkan bahwa fermentasi meningkatkan kadar fenol pada semua metode ekstraksi yang diuji. Kadar fenol tertinggi diperoleh pada perlakuan fermentasi yang dikombinasikan dengan metode maserasi etanol, yaitu sebesar 124,265 mg GAE/g, sedangkan kadar terendah terdapat pada perlakuan tanpa fermentasi dengan metode seduh dingin, yaitu sebesar 36,123 mg GAE/g. Metode ekstraksi maserasi etanol terbukti paling efektif dalam mengekstrak senyawa fenol jika dibandingkan dengan dekokta dan seduh dingin. Dengan demikian, kombinasi fermentasi dan maserasi etanol merupakan perlakuan terbaik untuk meningkatkan kadar total fenol pada tepung biji kurma.
