Pasien Infeksi ulkus kaki diabetik memerlukan penggunaan antibiotik, antibiotik yang sering digunakan mempunyai sensitifitas rendah dan beberapa pasien pada penggunaannya dalam keadaan resistensi, evaluasi efektifitas antibiotik perlu dilakukan untuk mengatasi masalah penggunaan antibiotik saat ini. Penelitian ini dilakukan dengan studi longitudinal dan teknik pengambilan sampel secara prospektif. Paramater yang diamati adalah keadaan leukosit, tanda infeksi dan demam seteleh pemberian antibiotik. Data yang terkumpul kemudian dianalisis secara deskriptif untuk menentukan efektifitas antibiotik berdasarkan literatur yang mendukung. Hasil perolehan sampel pada penelitian ini adalah sebanyak 19 sampel pasien infeksi ulkus kaki diabetik yang memenuhi kriteria dari 28 orang populasi terdiri dari 63,16% pasien laki-laki dan 36,84% pasien perempuan, 68,42 % usia 45-60 tahun dan lama diabetes terbanyak adalah > 10 tahun. Hasil evaluasi efektifitas antibiotik yaitu ditemukan 8 orang pasien yang menggunakan antibiotik secara dugaan (empiris) dan 11 orang pasien menggunakan antibiotik berdasarkan sensitifitas (definitif). Antibiotik efektif pada 15 orang subjek penelitian yaitu dapat memberikan respon pada leukosit, tanda infeksi dan parameter demam seteleh pemberian antibiotik 2-3 hari dan hasil terapi maksimal pada hari ke 7 sampai 21.
Chalcone analogs have been reported to have a variety of exciting biological activities, such as anticancer, anti-inflammatory, antioxidant, photoprotective, antibacterial, and antidiabetic activities. Therefore, analogs of these compounds have been widely synthesized as intermediate compounds or target molecules in the discovery of bioactive compounds to be applied in the pharmaceutical field. The purpose of this study is to synthesize chalcone analog compounds (E)-1-(4-hydroxyphenyl)-3-(4-methoxyphenyl) prop-2-en-1-on with the microwave irradiation method and explore some of the biological activities of these compounds, including testing the antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, in vitro sunscreen activity by microplate method, and antibacterial activity by disk diffusion method. DPPH test results indicate that the compound has weak antioxidant activity, with an IC50 value of 300.43 µg/mL. However, the compound showed excellent potential as a UV B and UV A filter at a concentration of 150 µg/mL with a value of %Te of 0.73±0.10% (sunblock), %Tp of 0.07±0.00% (sunblock), SPF value of 21.10±1.46 (ultra-protection) and potentially better than benzophenone-3 as a standard sunscreen. Then, disk diffusion testing showed that the compound had weak antibacterial activity against Staphylococcus aureus and did not show antibacterial activity against Escherichia coli bacteria at test concentrations of 30, 60, and 120 µg/disk.
Chalcone analogues have attracted the attention of researchers due to their various biological activities. In this study, a chalcone analogue, (E)-1-(3-hydroxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-on has been synthesized under microwave irradiation and its sunscreen activity has been evaluated by in vitro assay using 96-well microplate reader. Based on the in vitro assay, at concentration of 100-500 µg/ml, the compound showed potential sunscreen activity with %Te value of 5.49 – 0.04 % (extra protection – sunblock), %Tp value of 0.51-0.05 % (sunblock) and SPF value of 18.20 – 32.91 (ultra protection). The assay result showed that the (E)-1-(3-hydroxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-on has a potency to be developed as active ingredient in sunscreen product.
A new hybrid compound of chalcone-salicylate (title compound) has been successfully synthesized using a linker mode approach under reflux condition. The structure of the title compound has been established by spectroscopic analysis including UV-Vis, FT-IR, HRMS, 1D, and 2D NMR. Then, computational approach was also applied in this study through molecular docking and MD simulation to explore its potency against breast cancer. The results of the molecular docking study showed that the title compound exhibited more negative value of binding free energy (−8.15 kcal/mol) than tamoxifen (−7.00 kcal/mol). In addition, no striking change in the positioning of the interacting residues was recorded before and after the MD simulations. Based on the studies, it can be predicted that the title compound has a cytotoxic activity potency against breast cancer through ERα inhibition and it presumably can be developed as anticancer agent candidate.
Acne is a skin problem that often occurs, one of the causes is the bacterium Staphylococcus epidermidis. Black cumin seed oil (Nigella sativa L.) can be used as an antibacterial because it contains thymoquinone and α-pinene. This study aims to obtain black cumin seed oil emulgel preparations that has antibacterial activity against Staphylococcus epidermidis. The preparations were formulated with concentrations of 3% (FI), 5% (FII), and 7% (FIII). Evaluation of the preparation was carried out for eight weeks including organoleptic tests, spreadability, emulsion type, pH, viscosity, homogeneity. Antibacterial activity tests was carried out using the well-diffusion method. The results of the evaluation of all three formulas obtained showed a semi-solid consistency, light brown in color, characteristically smelled of black cumin seed oil, stable, M/A emulsion type, homogeneous, non-irritating, pH FI = 4.51-4.95, FII = 4.72-4.99, FIII = 4.57-4.87, dispersion FI = 3.2-3.8 cm, FII = 3.3-3.9 cm, FIII = 3.4-3.9 cm, viscosity FI = 10.7-26.1 Ns/m2, FII = 11.2-32.0 Ns/m2, FIII = 11.5-34.1 Ns/m2. The antibacterial activity test showed the inhibitory power of FI 11,66±0,09 mm, FII 14.48±0.03 mm, FIII 17.35±0,.8 mm, lower than the positive control (clindamycin). All three black cumin seed oil emulgel preparations obtained met the physical requirements and had bacterial inhibition (p
