Abstract

Hipertensi merupakan salah satu penyakit tidak menular yang memiliki prevalensi tinggi. Hipertensi disebabkan oleh terbentuknya Angiotensin II dari proses konversi dekapeptida inaktif Angiotensin I oleh angiotensin converting enzyme (ACE) yang akan menyebabkan penyempitan pembuluh darah. Selain itu, hipertensi juga dikaitkan dengan meningkatnya pembentukan reactive oxygen species (ROS). Pengembangan senyawa obat sebagai antihipertensi diperlukan untuk meningkatkan keberhasilan terapi yang belum adekuat. Sebagai salah satu senyawa bahan alam, kuersetin dipilih karena memiliki aktivitas sebagai ACE inhibitor yang diketahui dengan melakukan uji in silico terhadap induksi ACE. Analisis data dilakukan dengan melihat energi ikatan yang dihasilkan dan ikatan yang terbentuk antara senyawa dengan residu asam amino pada protein. Hasil penelitian ini menunjukkan bahwa senyawa kuersetin berpotensi mengatasi hipertensi. Validasi metode menunjukkan konformasi 7 memiliki nilai RMSD yaitu 2,86 Ã… dan energi ikatan antara protein target (ACE) dengan native ligan-nya yaitu -4.66 kkal/mol. Sedangkan nilai energi ikatan yang diperoleh antara senyawa uji kuersetin dan protein target yaitu -6,32 kkal/mol dimana ikatan hidrogen yang terbentuk menghasilkan residu asam amino ALA356, HIS383, ALA356, TYR523, dan GLU411 berturut-turut melalui gugus O-H, HE2-O, HN-O, HH-O, dan OE1-H. Nilai energi ikatan yang didapat menunjukkan bahwa senyawa uji kuersetin memiliki aktivitas farmakologi sebagai sebagai ACE inhibitor karena energi ikatannya lebih negatif dibandingkan dengan native ligand protein target yaitu lisinopril. Hal ini menunjukkan bahwa kuersetin dapat membentuk ikatan yang lebih stabil dibandingkan dengan lisinopril. Sehingga kuersetin berpotensi dalam pengembangan terapi hipertensi yang berperan sebagai ACE inhibitor.

Abstract

Moringa plants is very abundant in Indonesia. Moringa leaves are a source of polyphenol compounds, namely flavonoids. One of the main flavonoids found in Moringa leaves is quercetin. To be able to increase the concentration of quercetin from moringa plants, extraction is necessary. This study aims to determine the most optimal extraction method in extracting quercetin from Moringa leaves. Optimization of quersein extraction methods from Moringa leaves was carried out using maceration, soxhletation, and reflux methods. The solvent used was methanol acidified with 1,2 N HCl. Determination of the concentration of quercetin in the extract used a validated TLC-densitometry method. The highest rendement obtained from the maceration extraction method was 24.08 % w/w. Extraction by reflux and sochletation methods yielded rendement of 23.44 % w/w and 10.12 % w/w respectively. Qualitative analysis of quercetin in the extract was carried out by comparing its Rf value with the standard quercetin which is 0,4. The quercetin level of the extract from maceration extraction was the highest, which was 24.45 % w/w. Extraction using the soxhletation method obtained quercetin as much as 20.95 % w/w. Keywords: quercetin, Moringa oleifera leaves, extraction method, optimization

Abstract

Hyperpigmentation is caused by enhancement of melanin production that causes skin darkening. Purple sweet potato is one of the plants that is potentially developed as skin depigmentation agent because it contains anthocyanin. The most common types of anthocyanins in purple sweet potato are cyanidin and peonidin which are in vitro proven to be used as skin lightening. The objective of this study is to determine the potential of cyanidin and peonidin as skin depigmentation agent against target protein D-Dopachrome taumerase through in silico molecular docking method. The research steps include the preparation of target protein using Chimera 1.10.1 program, optimization of cyanidine and peonidin 3D structures using Hyperchem 8 program, validation of molecular docking method, and docking of cyanidine and peonidine on target protein using Autodock 4.2 program. The bond energy between cyanidin and peonidin with the target protein D-Dopachrome taumerase are -7.75 kcal / mol and -8.38 kcal / mol. The cyanidin and peonidin bond values ??are smaller than the native ligand, suggesting that the bond between the test compound (cyanidin and peonidin) with the target protein are stronger and more stable than the native ligand, so that the affinity of the test compound was greater than the native ligand. This suggests that the cyanidin and peonidin compounds in purple sweet potato have potential as a depigmentation agent by inhibiting D-Dopachrome taumerase protein.

Abstract

Darkening of the skin results from excessive production of melanin in the skin caused by an increase in tyrosinase related protein 1 enzyme activity. Catechins are flavonoid compounds which contain antioxidants. This study aims to determine the affinity and mechanism of catechins as skin lightening agents by inhibiting tyrosinase related protein 1 target proteins in silico using molecular docking methods. The study was carried out exploratively with the stages of preparing a database of 3D structures of catechins and tyrosinase related protein 1, optimization of 3D structure of catechins, protein preparation, validation of molecular docking methods, and docking of catechins in tyrosinase related protein 1. Docking results are assessed from the bonding energy and hydrogen bonds formed between catechins and proteins. The smaller the bond energy value, the stronger the bond between the catechins and proteins. The results showed that catechins had activity as skin lightening agents because they were able to inhibit the tyrosinase related protein 1 with a bond energy value of -6,35 Kcal/mol. The energy value of the catechin bond with the tyrosinase related protein 1 is smaller than the tyrosinase related protein 1 with its native ligand. This shows that catechins have greater potential and affinity in inhibiting the tyrosinase related protein 1 enzyme with hydrogen bonds on amino acid residues, namely ARG374. Based on the results obtained, catechins have activity as skin lightening agents with the mechanism of inhibiting the tyrosinase related protein 1 enzyme so that the amount of eumelanin formed is less and the skin becomes brighter. Key words: catechins, skin lightening, tyrosinase related protein 1, in silico, molecular docking
