Abstract

The ethyl acetate fraction separated from the stembark of Sonneratia caseolaris retrieved three phenolic compounds, including quercetin-3-O-glucoside (1), quercetin (2), and 1-O-(2,4-dihydroxybenzoyl)-β-D-glucopyranose (3). For the first time, compounds 1 and 3 were discovered from Sonneratia genus. Data from various spectroscopic techniques, including mass spectroscopy and one- and two-dimensional NMR, were used to identify their chemical structures. Antibacterial activity has also been assessed for all compounds against Staphylococcus aureus ATCC 25175 and Streptococcus mutans ATCC 6538. Compounds 1–3 displayed varying levels of antibacterial activity against S. aureus and S. mutans. However, all compounds exhibited lower efficacy compared to the control, with their minimum inhibitory concentration (MIC) values ranging from 71.25 to greater than 100 µg/mL. This study provides a foundation for optimizing S. caseolaris phenolic compounds as antibacterial agents and highlights the need for comparative studies within the Sonneratia genus to identify potent bioactive candidates through structural modification or synergistic approaches.

Abstract

The Garcinia genus comes from the Clusiaceae family which grows a lot in the tropical forests of Indonesia. This genus is reported to contain many secondary metabolites, one of which is triterpenoid which is useful as a cytotoxic, anti-oxidant, anti-inflammatory, anti-HIV, and antibacterial. One species of Garcinia whose triterpenoid content is still not widely known is G. cymosa. This study aims to obtain triterpenoid compounds in G. cymosa stem bark that are active against MCF-7 breast cancer cells. G. cymosa stem bark powder (0.9 kg) was macerated in stages with n-hexane and ethyl acetate as solvents. The ethyl acetate extract showed positive results for containing triterpenoid compounds after being tested with the Liebermann-Burchard reagent, so the ethyl acetate extract (25 g) was purified and purified by various chromatographic methods. The chemical structure of pure isolate (10 mg) was determined using various spectroscopic techniques IR, MS, 1H-NMR, 13C-NMR, 1H-1HCOSY, HMQC, and HMBC and compared with the literature so that it was designated as triterpenoid acid 3β-hydroxy-5- gluten-28-oat and required its cytotoxic activity using the Presto Blue method against MCF-7 breast cancer cells with an IC50 value of 94.78 µg/mL. This IC50 value belongs to the active category so this compound has potential as an anticancer drug.

Abstract

Diabetes Melitus adalah penyakit kronis yang ditandai dengan kadar gula darah tinggi akibat gangguan sekresi dan fungsi insulin. Jika tidak terkontrol, penyakit ini dapat menyebabkan komplikasi serius. Diabetes Melitus Tipe 2 merupakan jenis yang paling umum, terutama disebabkan oleh pola hidup tidak sehat dan kurangnya aktivitas fisik. Secara global, jumlah penderita terus meningkat, termasuk di Indonesia yang menempati peringkat ke-5 dunia dengan 19,5 juta kasus pada 2021. Di Kalimantan Selatan, prevalensinya cukup tinggi, termasuk di Kabupaten Balangan, yang mengalami peningkatan signifikan dalam beberapa tahun terakhir. Mengetahui pengalaman keluarga dalam merawat pasien dengan Diabetes Melitus Tipe 2 di Puskesmas Awayan Kabupaten Balangan. Penelitian ini menggunakan pendekatan kualitatif dengan metode fenomenologi deskriptif. Pengambilan data dilakukan melalui wawancara menggunakan pedoman wawancara yang berkaitan langsung dengan pengalaman keluarga dalam merawat pasien Diabetes Melitus Tipe 2 di Puskesmas Awayan Kabupaten Balangan. Hasil penelitian menunjukkan bahwa dukungan keluarga berperan penting dalam meningkatkan kepatuhan pasien Diabetes Melitus tipe 2 terhadap pengobatan. Dukungan ini mencakup aspek informasional, penilaian, instrumental, dan emosional, yang secara bersama-sama berkontribusi terhadap kualitas hidup pasien. Selain itu, keluarga berperan sebagai pendamping dalam perawatan, membantu pasien memahami anjuran medis, serta memberikan motivasi untuk menjalani gaya hidup sehat. Peran perawat juga krusial dalam memberikan edukasi dan memastikan keluarga memiliki pemahaman yang cukup untuk mendukung perawatan pasien di rumah. Oleh karena itu, komunikasi yang efektif antara perawat dan keluarga diperlukan agar dukungan yang diberikan lebih optimal.

Abstract

Introduction: Streptococcus mutans has been known to play a major role in dental caries development. This tooth decay is the most common oral disease affecting people in the world. Hence, discovering the new herbal antibacterial agent seems to become more promising yet challenging. One of natural antibacterial source is the peel of Citrus aurantifolia, as it may contain antibacterial active compounds against pathogenic oral microbes. This study was aimed to isolate antibacterial compound from essential oil of Citrus aurantifolia and to analyse its antibacterial activity against oral Streptococcus mutans ATCC 25175. Methods: Type of research was laboratory experimental. The essential oil was isolated from peel of Citrus aurantifolia by hydro-distillation technique and further isolation of antibacterial compounds was conducted by combination column chromatography using organic solvent, and the structure was determined by UV-Vis, infrared (IR), 1D NMR of 1H-, 13C-NMR and DEPT 135° in CDCl3 spectrometers methods. The antibacterial activity was tested against Streptococcus mutans ATCC 25175 using the Kirby-Bauer method. Results: 0.75% yield was obtained from the essential oil of peel Citrus aurantifolia and after purification, an antibacterial compound was identified as β-pinene with the molecular formula C10H16. Furthermore, the β-pinene from peel of Citrus aurantifolia exerted inhibition growth against Streptococcus mutans at concentration of 2000, 1000, and 500 ppm by showing respectively, inhibition values of 13.0, 11.9, and 11.6 mm on paper disk. Conclusion: In the present study, the essential oil of Citrus aurantifolia peel is proven to contain prospective antibacterial compound (β-pinene) that potentially can be used as natural antibacterial alternative choice to manage oral disease associated with Streptococcus mutans infection.

Abstract

Disobinol is a limonoid compound from the seeds of the Chisocheton macrophyllus plant that has been reported to have anticancer activity against cervical cancer cell lines. Cervical cancer is a type of cancer caused by infection with Human papillomavirus (HPV) types 16 and 18, leading to the transformation of normal cervical epithelial cells into cancerous cells. Previous studies show that Disobinol has a cytotoxic effect on HeLa cells with the IC50 value 52,92 μg/mL (24 hours’ incubation). This study aims to determine the level of apoptosis in HeLa cells treated with Disobinol and observe the DNA fragmentation in HeLa cells undergoing apoptosis. The HeLa cells were treated with Disobinol at concentrations of 26,5 μg/mL (1/2 IC50), 52,3 μg/mL (IC50), and 104,6 μg/mL (2x IC50) and incubated for 24 hours. The level of apoptosis was analyzed by using flow cytometry, and the DNA fragmentation pattern was analyzed by agarose gel electrophoresis. The results showed that Disobinol induces early apoptosis in HeLa cells, although the difference in the percentage of cell death is not very significant, which were 37.05%, 37.7%, and 41.60%, respectively. The DNA fragmentation pattern in HeLa cells treated with various concentrations of Disobinol was also observed on agarose gel. Therefore, Disobinol has the potential to be used as a chemotherapeutic drug or as a lead compound for the treatment of cervical cancer.
