Abstract

Chisocheton is a large source of limonoids with various pharmacological effects, such as antiviral, antibacterial, antimalarial, antifungal, and cytotoxic activities. This study aimed to isolate, elucidate, and evaluate the cytotoxicity of limonoids from C. pentandrus stembarks. Isolation was carried out using various separation methods including extraction and column chromatography. Spectral data were analyzed by FT-IR, UV, DEPT 135°, 1H, 13C-NMR, and HRTOF-MS and compared with those previously reported to determine the chemical structure.The obtained limonoids were lasiocarpine (1), lasiocarpine B (2), pentandricine (3), and 16β-hydroxydysobinin (4); all of which were successfully isolated from C. pentandrus for the first time. The cytotoxic activity of these limonoids were also evaluated against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells using PrestoBlue method. Lasiocarpine A revealed the strongest cytotoxicity with an IC50 of 42.62 µM in moderate level.

Abstract

Naphthalene derivative compounds named Eleutherol (1) and Eleutherol C (2) have been isolated from Bawang Tiwai Bulb Eleutherine bulbosa. We tested its cytotoxic activity against T47D breast cancer cells in vitro after isolating compounds 1 and 2 from the EtOH extract using conventional chromatography methods. Their chemical structures were elucidated based on spectroscopic analysis, including IR, HR-TOFMS, 1D, and 2D NMR, and by comparison to those related spectra previously reported. Compounds 1 and 2 were tested for their cytotoxic effects against T47D breast cancer cells and showed moderate cytotoxicity against T47D breast cancer cells with IC50 values of 117.15 and 80.21 µM, respectively, compared with cisplatin 24.07 µM.

Abstract

This study evaluates the viability of a problem-based learning (PBL) e-module on elements, compounds, and mixtures through validation by experts and feedback from both teachers and students. This study adopted a research and development (RD) methodology guided by the ADDIE framework. The participants consisted of teachers and students from SMPN 10 Pontianak. The data were gathered using an indirect communication method, specifically through feasibility assessment sheets and questionnaires filled out by both teachers and students. The results indicated that the e-module was considered highly suitable for use. The validity coefficient were 1.00 from graphic design experts (categorized as very good), 0.83 from linguists (very good), and 1.00 from subject matter experts (very good). The average coefficient from experts validation was 0.94, which fall into the very good category. In addition, teacher and student responses also indicated very good results: for the media aspect, each response rates were 92% and 85%; for the content aspect, 85% and 83%; and for usefulness, 86% and 85%. These results suggest that the PBL-based teaching e-module is suitable and ready to be used in learning activities

Abstract

The chalcone compound is a precursor of flavonoid and pyrazoline compounds. Chalcone has two aromatic rings (A and B) and one ?,?-unsaturated carbon atom. Chalcone compounds can be synthesized via the Claisen Schmidt condensation reaction. Chalcone synthesis uses the basic ingredients of alpha tetralone and benzaldehyde analogues. In this research, chalcone synthesis took place for 48 hours at room temperature. Synthetic materials using ethanol solvent and sodium hydroxide catalyst, as well as basic ingredients alpha tetralone, 3,4-dimethoxybenzaldehyde and 4-methoxybenzaldehyde. Characterization of synthesized compounds using spectroscopic methods, including 1H-NMR, 13C-NMR, Fourier Transform Infrared (FTIR) and mass spectroscopy. Characterization results using spectroscopic methods showed that the two chalcone analogue compounds were successfully synthesized with yields above 70%. Both chalcone compounds showed low activity against MCF-7 cancer cells. Molecular docking simulations showed that both chalcone analogues produced energy levels and intramolecular interactions that were no better than 4-hydroxytamoxifen. Keywords:          chalcone analogues, alpha tetralone, cytotoxic   Abstrak Senyawa kalkon merupakan salah satu prekursor dari senyawa flavonoid dan pirazolina.
