Abstract

Ethanol extract of Piper crocatum leaves has inhibitory activity of α-glucosidase enzyme. Ethyl acetate fraction from Piper crocatum leaves has the highest antioxidant activity. Previous research has provided information that the ethyl acetate fraction of Piper crocatum leaves has an inhibition of α-glucosidase containing 6XO32ZSP1D, Ethyl L-serinate hydrochloride compound, Schisandrin B compound, Columbin compound, 4- (4-methoxy-phenylamino) -2 compound, 3-dihydro-1H-4a, 9-diazacyclopenta (b) fluorine-10-carbonitrile, compound 6-Amino-4- [3- (benzyloxy) phenyl] -3-tert-butyl-2,4-dihydropyrano [2, 3-c] pyrazole-5-carbonitrile, compound 4 - {{4.6-Bis [(3R, 5S) -3,5-diamino-1-piperydinyl] -1,3,5-triazine-2-yl} amino) benzenesulfonamide and compound 1.1 '- (1,4-butanediyl) bis {2,6-dimethyl-4 - [(3-methyl-1,3-benzothiazol-2 (3H) ylidene) methyl] pyridinium. This study aims to study the interaction between bioactive compounds contained in ethyl acetate fraction of Piper crocatum leaves with α-glucosidase enzyme in In Silico using AutoDock Vina, Columbin shows the lowest binding energy with binding sites with amino acids Ser240, Asp242, His280, Arg315, Glu411, Phe159, Arg442, Tyr158 and Phe303. Columbin has the stability and inhibits the α-glucosidase enzyme from S. cerevisiae better than the seven other compounds, because it has OH and CH3 groups which play a role in the interaction with around the active side of the α-glucosidase enzyme.Keywords: Columbin, In Silico, α-Glucosidase

Abstract

Melasma is a skin disorder characterized by hyperpigmentation of the skin in areas exposed to sunlight and is included in the dominant skin disorder category in several countries. Meanwhile, data from the Food and Drug Administration shows that cosmetic products have progressed from 0.01% to 57.4% in terms of registered products over the last six years. Currently, melasma treatment and cosmetic applications as a whitening agent were carried out by regulating tyrosinase activity through the use of compounds such as kojic acid which poses a health risk. Therefore, it was necessary to have other alternatives that can regulate tyrosinase activity without harming health. This study aimed to determine inhibitory effects of wungu leaf (Graptophyllum pictum (L) Griff) bioactive component as an agent to inhibit tyrosinase activity through a molecular docking approach. A total of 28 wungu leaves bioactive components as a result of the analysis of Gas Chromatography-Mass Spectrometry (GC-MS) and Gas Chromatography-Flame Ionization Detector (GC-FID) were tested for their inhibitory effects on tyrosinase activity. Linolenic acid and phytol were ligands that have the best inhibition on tyrosinase enzyme activity with affinity energies of -5.8 kcal/mol and -5.4 kcal/mol, respectively, and inhibition constants of 55.718 M and 109.489 M.

Abstract

Degenerative diseases occurred due to several risk factors that are directly related to inflammationwhich affected several diseases such as coronary heart disease (CHD) and diabetes. One of theinflammatory causative agents is leukotrienes produced by the lipoxygenase enzyme (LOX) so thatit takes anti-inflammatory drugs made from herbal plants. Red betel leaf (Piper crocatum) potentiallyinhibited the lipoxygenase enzyme because it contains potential phytochemical compounds suchas alkaloids, flavonoids, eugenol, saponins, and tannins. This research aimed to test the inhibitionof active compounds from extract and fractions of red betel leaves that have the best inhibition forlipoxygenase enzymes causing malondialdehyde formed through molecular docking simulations. Thisresearch used lipoxygenase enzyme as receptor (PRB code: 4NRE), C8E as natural ligand and activecompound from extract and fractions of red betel leaves as a ligand. The highest inhibition regarded toNandrolone phenylpropionate and Sofalcone ligand with -10.4 kcal/mol and -9.1 kcal/mol of affinityenergy. Amino acid residues that played a role in ligand and receptor interaction were HIS373 andHIS378. The receptor structure with the best ligands was declared stable based on molecular dynamicssimulations.

Abstract

Melasma adalah kelainan pigmentasi yang diakibatkan sintesis melanin berlebih berupa bercak cokelat disekitar wajah atau leher. Melasma dapat mengenai semua kelompok ras, terutama daerah dengan radiasi ultraviolet tinggi seperti suku Hispanik/Latin dan Asia. Zat yang sering digunakan untuk mencegah hiperpigmentasi adalah asam kojat, asam azelat dan merkuri, akan tetapi zat tersebut bersifat karsinogen jika digunakan terus menerus. Sirih merah (Piper crocatum) memiliki senyawa aktif yang berperan sebagai antioksidan seperti flavonoid dan fenol. Penelitian ini bertujuan untuk mengetahui potensi senyawa aktif daun sirih merah terhadap penghambatan tirosinase. Penelitian ini dilakukan dengan metode in silico dan in vitro. Reseptor yang digunakan adalah tirosinase dengan kode PDB 5M8O, tropolon sebagai native ligand, dan asam kojat sebagai ligan pembanding. Sebanyak 34 senyawa aktif daun sirih merah hasil analisis LC-MS dan GC-MS.digunakan sebagai ligan uji. Penambatan molekuler dilakukan dengan menggunakan AutoDock Vina dan AutoDock Tools, serta divisualisasikan menggunakan Ligplot+ dan PyMOL. Penghambatan tirosinase secara in vitro menggunakan kit tyrosinase activity assay ab252899 dan asam kojat sebagai kontrol positif. Senyawa katekin memiliki energi bebas pengikatan (ΔG) terkecil, yaitu −6.7 kkal/mol, dan kinetika inhibisi sebesar 12.12 µM. Hasil pengujian in vitro, fraksi air memiliki aktivitas inhibisi tirosinase terbesar yaitu 84.84% dan asam kojat memiliki aktivitas sebesar 82.47%.
