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

This study deals with endophytic microbes, known as a potential source of secondary metabolites. The microbes (F) were isolated from Cinchona pubescens Vahl and fermented in Phoma media, observing the pH, biomass growth and secondary metabolites of alkaloids for 14 days. The result obtained showed that the pH was between 4 and 5, the biomass growth relative stable after 8 days and the production of alkaloids reached its maximum also after 8 days (32.81 mg/l).

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

Synthesis of 1,5-bis(3’-etoxy-4’-hydroxyphenyI)-1,4-pentadiene-3-on (EHP) by aldol condensation method from ethyl Vanilin and acetone, using hydrochloride acid as a catalyst, has been conducted. Identification of the EHP compound was done through interpretation of UV-Vis, FT-IR, GC-MS and NMR data, The antioxidant activity of EHP (IC50 8.66 µg/mL) is higher than curcumin (IC50 11.44 µg/mL) as demonstrated by the DPPH method.

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

Teh hijau dikenal banyak memiliki manfaat dan umum digunakan masyarakat sebagai antiobesitas, tetapi senyawa aktif yang berpotensi sebagai antiobesitas. Tujuan penelitian untuk mencari bahwa senyawa kimia yang terdapat dalam tanaman teh hijau mempunyai aktivitas sebagai antiobesitas pada reseptor PPAR-γ. Metode penelitian dilakukan dengan cara analisis in silico melalui molecular docking terhadap senyawa yang terdapat dalam tanaman teh hijau untuk mencari senyawa aktif dan memodelkan interaksi senyawa aktif pada reseptor yang berperan sebagai antiobesitas. Software yang digunakan adalah PLANTS, YASARA, ChemSketch, dan Pymol. Mula-mula dilakukan validasi internal pada reseptor PPAR-γ dengan kode 2ATH. Proses docking dilakukan terhadap native ligand, senyawa pembanding dan masing-masing senyawa uji dengan reseptor PPAR-γ yang sama, dan senyawa pembanding yang digunakan sebagai kontrol positif ialah Pioglitazone. Hasil penelitian menunjukan sisi aktif terdapat 3 senyawa aktif dengan sisi aktif ikatan ligan pada reseptor PPAR-γ yaitu ARG288, LYS367, PHE363, HIS323, HIS449, ILE326, MET364, LEU340, CYS285, SER342. Terdapat 3 senyawa aktif yaitu epigalokatekin-3-galat, epikatekin-3-galat dan teaflavin sebagai antiobesitas dengan mekanisme kerja mengaktivasi PPAR-γ.
