Abstract

Diabetes Mellitus (DM) is a degenerative disease that can cause various complications such as cardiovascular, stroke, and hypertension. Antidiabetic drugs that are commonly circulated in the market, have side effects that can harm other organs such as liver, kidneys and other organs. Bay leaves have properties as inhibitors of the α-glucosidase enzyme in vitro and in vivo. The aims of this study was determine the activity of ethanolic extract of bay leaves by ultrasonic extraction method in inhibiting the α-glucosidase enzyme in vitro and in silico. Bay leaves were extracted using 70% and 96% ethanol by ultrasonic method for 15 minutes, and filtered and concentrated using a rotary vacuum evaporator 4 times. The extract obtained was tested for phytochemical content and the activity of α-glucosidase inhibitory assay. The extract with the best IC50 value was then separated using column chromatography (SiO2, dichloromethane, methanol) and produced 7 fractions and tested for α-glucosidase enzyme inhibition. The best fraction (fraction 6) was analyzed by Liquid Chromatography Mas Spectra (LCMS-MS). The results showed that bay leaf extract containing alkaloids, flavonoids, tannins, steroids, phenols, and fraction-6 had the best IC50 of 30.82 ppm. The results of LCMS-MS analysis of chemical compounds as inhibitors of the α-glucosidase enzyme were delphinidin (m/z 303) and had a rerank score of -75.59. In the in silico test using PLANTS docking software.

Abstract

Cyclooxygenase-2 (COX-2) inhibitors are high demand drugs in the market. However, available COX-2 inhibitors nowadays have many side effects. Therefore, there is still a need to develop more potent selective COX-2 inhibitors and one of the method that has been prove the effectivity and eficiency for new drugs research is in silico. Structure-based virtual screening (SBVS) protocols were developed to find COX-2 inhibitors using the Protein-Ligand ANT System (PLANTS) docking software, SPORES, BKChem and Open Babel. The directory of useful decoys (DUD) dataset for COX-2 was used to validate the protocols retrospectively; the DUD consist of 426 known COX-2 inhibitors and 13289 decoys. Based on criteria value of EF20% and EFmax used in the article from Huang et al (2006) and Yuniarti et al (2011), two validated protocol, AYO_COX2_v.1.1 and AYO_COX2_v.1.2 , showed good results

Abstract

The 1,5-bis(3’-ethoxy-4’-hydroxyphenyl)-1,4-pentadiene -3-one (EHP) is a curcumin analogue. The structure has also been identified before. EHP is obtained, which has been pharmacologically proven to have higher antioxidant activity than curcumin. The objectives of this research were to determine the acute toxicity (LD50) of EHP compound by Weil C.S. method using male mice as experimental animals and to determine its antiinflammatory activity. The LD50 value of the synthesized EHP compound is 6,8675 g/kg body weight (bw) with the criteria of mild toxic, so it is assumed to be safe as drug substance candidate. The anti-inflammatory activity of the compound was determined by obeserved legs swelling index of the mouse. Anti-inflammatory activity of EHP with doses of 137.35 mg, 274.70 mg and 549.40 mg were equal to aspirin with the dose of 90 mg/200 g bw

Abstract

Brown seaweed has been known as a fucoidan source that has various biological activities. Fucoidan could be obtained by various extraction methods. This study aims to extract, characterize and to evaluate the antioxidant activity of crude fucoidan extracted from Sargassum cinereum. Extraction was carried out by refluxing at 100oC for 4 and 5 hours and then precipitated with ethanol. The crude fucoidan was brown powder. The yield with 4 hours extraction time was 2.78% which did not differ significantly from the 5 hours extraction time. Phytochemical screening of crude extract showed that beside fucoidan there were flavonoids, saponins, steroids, triterpenoids, and tannins. The extraction with duration of 4 hours and 5 hours had sulfate content of 16.31% and 11.22%, total carbohydrate content were 22.94% and 22.85%, and in the FTIR spectrum showed OH absorption bands of carbohydrates, fucose, sulfates and uronic acid. Testing of antioxidant activity using the DPPH (1,1-diphenyl-2-picrylhyrazyl) free radical inhibition method produced IC50 values ​​of 721.9 µg/ml and 749.9 µg/ml respectively and it was concluded that crude fucoidan of Sargassum cinereum had weak antioxidant activity.

Abstract

Some studies state that curcumin analog compounds can improve the bioavailability and biological activity of curcumin. One of the methods to predict the bioactivity of curcumin was computational using molecular docking method. This study has done bioactivity tests of curcumin analog compounds as antiviral using the molecular docking method with the software used are PLANTS, YASARA, MarvinSketch, and Pymol for visualization. This study used analog curcumin compounds derived from previous research. This study used five different viral reseptor types. The maraviroc, docosanol, ribavirin, and zanamivir were used as compound control in this research. The validated target protein consists of 5 (five) receptors with PDB codes 1V2I, 4WEG, 2HWI, 2QAD, and 3ALP. Based on this research, compounds that are predicted active as antiviral on each receptors that are: 2,5-bis(3,5-ditertbutyl-4-hydroxy benzyl)cyclopentanone (1V2I), 1,7- diphenyl-1,6-heptadiene-3,5-dione (4WEG), 1,7-bis(3,4-dibenzyloxiphenyl)-1,6-heptadiene-3,5-dione (2HWI), and 2,5-bis(3,5-ditertbutyl-4-hydroxybenzyl)cyclopentanone (3ALP).

Abstract

Annonaceae adalah familia dengan 800 spesies yang tersebar di seluruh dunia. Beberapa penelitian menunjukkan bahwa annonaceae memiliki aktivitas biologis sebagai antikanker dan telah digunakan sebagai obat herbal secara empiris. Pada penelitian ini dilakukan penapisan virtual beberapa struktur senyawa dari tanaman familia Annonaceae. Tujuan penelitian ini adalah untuk menganalisis dan memperoleh kandidat senyawa yang aktif sebagai ligan pada reseptor estrogen alfa yang dapat memicu timbulnya kanker payudara, selanjutnya akan dilakukan elusidasi moda ikatan senyawa representatif aktif dan inaktif untuk melihat interaksi asam-asam amino pada binding site senyawa tersebut. Penelitian ini menggunakan protokol tervalidasi hasil penelitian Anita dkk., 2012 dengan berbagai aplikasi komputasi seperti SPORES, PLANTS, BKchem, OpenBabel dan PyMol. Hasil penapisan virtual menunjukkan bahwa dari 39 kandidat senyawa ada 18 senyawa dari tanaman familia Annonaceae yang memiliki nilai ChemPLP lebih kecil daripada ligan pembanding, artinya ada 18 senyawa yang memiliki afinitas yang lebih baik terhadap reseptor sehingga dapat mencegah timbulnya kanker payudara.
