Abstract

In this study, titled compound 5 has been successfully synthesized with 93% yield. The pyrazoline compound was obtained from the cyclocondensation reaction of 4-hydrazinylbenzenesulfonamide 3 with chalcone (E)-3-(2,3-dimethoxyphenyl)-1-(4-methoxyphenyl)prop-2-en-1-one 4 under basic conditions. The molecular structure was confirmed through analysis of FTIR, NMR and HRMS spectroscopic data. Furthermore, its tyrosinase enzyme inhibitory activity was determined through in vitro assay against tyrosinase of Agaricus bisporus. However, the pyrazoline compound 5 showed lower inhibitory activity than the positive control, kojic acid, whereas the IC50 value of the compound 5 is higher than that of kojic acid. The compound 5 IC50 value was 262.15 µM, while kojic acid IC50 value was 88.52 µM.

Abstract

A study on the uptake of Pb in the organ system of carp was carried out in the laboratoryscale. The research aims to identify the uptake rate of Pb in the gill, intestine and muscle ofthe fish. A completely randomized design was done in the experiment laboratory with threetreatments and three replications. The total of 120 fish were exposed to three concentrationsof Pb (1, 3 and 5 ppm of PbNO3) in nine aquarium for 168 hours. Pb concentration in the organsystem of fish were analyzed at 24, 96 and 168 hours, respectively. The concentration of Pbin the intestine were 0.29, 0.44 and 0.47 ppm, for 24, 96 and 168 hour exposure, respectively.Meanwhile, Pb content in the gill were 0.21, 0.39 and 0.45 ppm, respectively. It revealed thatPb concentration in all organs of fish increased significantly (P<0.05) following increased ofexposure time.

Abstract

Chalcone is a flavonoid derivative that has a variety of interesting biological activities. One of the compounds suspected of being an antibacterial agent is chalcone. The properties of chalcone compounds depend on the substituents that depend on the two aromatic rings, such as Cl, Br, OH groups and so on. The purpose of this study was to synthesize chalcone analogue compounds and determine the potential of these analog compounds as antibiotics. In this research, a chalcone analogue compound has been successfully synthesized, namely 3ꞌ-Bromo-4-methoxy-chalcone through the stirring method using KOH catalyst, ethanol solvent. The results of the synthesis carried out by recrystallization and the yield obtained were 64 %. Identification of compounds that have been carried out by TLC test, melting point, and HPLC analysis. The structure of the compound was characterized by UV-Vis spectroscopy, FTIR and 1H NMR, indicating that the analogue chalcone compound has a structure as expected. Testing the activity of chalcone analogue compounds was carried out on Staphylococcus aureus and Escherichia coli at a concentration of 1%, 5%, 10% and 20% test solutions. The test results showed that the antibacterial activity of the compound 3ꞌ-Bromo-4-methoxy-chalcone was categorized as weak.

Abstract

Three types of cyclopentanone derivatives have been synthesized from aromatic aldehyde and ketone derivatives under a base condition through aldol condensation. These cyclopentanone products were 2,5-dibenzylidene-cyclopentanone (a), 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (b), and 2,5-bis-(4-hydroxy-benzylidene)-cyclopentanone (c) which has a yield of 63-99%. The chemical structure of these compounds were determined using UV, IR and NMR spectroscopy. In order to clarify the role of hydroxyl and amine moieties, toxic, antioxidant and anti-inflammatory activities were carried out. The toxic test indicated that the compounds showed strong toxicity. In addition, the presence of hydroxyl and amine groups on both rings of curcumin increased the antioxidant and anti-inflammatory activities.

Abstract

Pyrazoline is well-known as heterocycles compound that can exhibit many biological effects. In this work, we synthesized a series of sulfonamide-substituted 1,3,5-triphenyl pyrazoline compounds as a promising tyrosinase inhibitor agent. These compounds prepared by multicomponent reaction of corresponding aldehyde, ketone, and hydrazine using seal-vessel reactor. Pyrazolines compound were tested for their tyrosinase inhibitor activity through in vitro assay. The test result found that compound 4c, 4d, and 4e possessed better tyrosinase inhibitory activity compared to the reference drug, kojic acid. Compound 4c exhibited the strongest tyrosinase inhibitory effect with an IC50 value of 30.14 µM. The results suggested that hydroxyl and methoxy substituent at para position are preferable. Furthermore, molecular docking studies result match the pattern of in vitro assay where the compound will provide a stronger binding interaction and lower binding free energies.

Abstract

Kalkon (1,3-diaril-2-propen-1-on) merupakan golongan flavonoid yang memiliki banyak aktivitas salah satunya sebagai antidiabetes. Pada penelitian ini dilakukan sintesis tiga senyawa analog kalkon yaitu 2’-hidroksi-2-metoksi-kalkon (Kalkon1), 2’-hidroksi-3-metoksi-kalkon (Kalkon2) dan 2’-hidroksi-4-metoksi-kalkon (Kalkon3) dan serta dilakukan pengujian karakterisasi nya. Sintesis analog kalkon  dilakukan dengan metode irradiasi microwave menggunakan  katalis KOH, pelarut etanol dan PEG 400. Struktur setiap produk dikarakterisasi melalui spektroskopi UV-Vis, FTIR dan 1H NMR, menunjukkan bahwa ketiga senyawa analog kalkon hasil sintesis memiliki struktur sesuai dengan yang diharapkan, dengan hasil rendemen yaitu 91,53% (Kalkon1), 79,01% (Kalkon 2) dan 77,48% Kalkon 3. Berdasarkan studi in silico dari parameter nilai energi bebas ikatan didapatkan bahwa senyawa Kalkon 3 memiliki nilai energi bebas ikatan terkecil yaitu sebesar -8,8 kcal/mol dibandingkan senyawa Kalkon1 dan Kalkon2 yaitu sebesar -7,5 kcal/mol, -6,8 kcal/mol. Untuk  parameter  kecocokan asam amino dengan kontrol positif (akarbose), hanya senyawa Kalkon1 yang memiliki kecocokan dengan kontrol positif (akarbose) sedangkan untuk parameter ikatan hidrogen didapatkan bahwa semua senyawa uji tidak menunjukkan adanya interaksi berupa ikatan hidrogen antara ligand dan reseptor. Hasil ini menunjukkan senyawa Kalkon1, Kalkon 2 dan Kalkon 3 diperkirakan tidak aktif sebagai inhibitor enzim α-glukosidase.
