Mekanisme Katekin Sebagai Obat Antidislipidemia (Uji In Silico)
Abstract
Indonesia has a large biodiversity that can be used as a medicinal plant, one of that is Gambir. The high content of catechin in gambir has the potential to be an antidyslipidemic drug. The mechanism of catechin as antidyslipidemic drug can be traced using a molecular docking study which is one of the studies of the in silico study model used to filter compounds based on their mechanism of action against target proteins. In this study, the molecular docking of catechin was done using Molecular on Environment Software (MOE) to identify the affinity and interaction with HMG-CoA reductase and LDL enzymes that contribute to fat/cholesterol metabolism. The results of molecular docking showed that catechin interaction against HMG-CoA reductase and LDL receptor enzymes had Gibbs value of -6,5758 kcal/mol and -16,1709 kcal/mol, respectively. Potential catechin action mechanisms as antidyslipidemic use two pathways, inhibition of HMG-CoA reductase enzyme and increased LDL receptor.
Abstrak
Indonesia memiliki kekayaan hayati yang besar dan dapat dimanfaatkan sebagai tanaman obat, salah satunya gambir. Kandungan senyawa katekin yang tinggi dalam gambir berpotensi sebagai antidislipidemia. Mekanisme katekin sebagai antidislipidemia dapat ditelusuri menggunakan studi docking molekuler yang merupakan salah satu studi model studi in silico yang digunakan untuk menapis senyawa berdasarkan mekanisme kerjanya terhadap protein target. Pada penelitian ini senyawa katekin dilakukan docking secara molekuler dengan menggunakan Software Moleculer on Environtment (MOE) dengan tujuan untuk mengetahui daya afinitas dan interaksinya terhadap enzim HMG-CoA reduktase dan reseptor LDL yang berperan terhadap metabolisme kolesterol. Hasil docking molekuler menunjukkan bahwa interaksi katekin terhadap enzim HMG-CoA reduktase dan reseptor LDL memiliki nilai Gibbs masing-masing sebesar -6,5758 kacl/mol dan -16,1709 kcal/mol. Potensi mekanisme aksi katekin sebagai antidislipidemia menggunakan dua jalur yaitu penghambatan enzim HMG-CoA reduktase dan peningkatan reseptor LDL.
