Abstract

ABSTRACT. Triterpenoids are a large group of secondary metabolites commonly found in plants, exhibiting high diversity in both structural features and biological activities. Meliaceae family is knows as a rich source of the triterpenoid compounds. As the most extensive genus within the Meliaceae family, Aglaia is known to contain many bioactive triterpenoid compounds, including cytotoxic triterpenoids. Among the various types of triterpenoids, dammarane is frequently found in Aglaia and has demonstrated potential cytotoxic activity. This purpose of the research was to isolate and structure determination of four dammarane triterpenoids from the methanol extract of Aglaia eximia stem bark. All four compounds were successfully isolated and identified as, dammar-24-en-3a,20-diol (1), 20S,24S-epoxy-dammar-3a,25-diol (2), (E)-dammar-23-en-3a,20,25-triol (3), and (E)-25-hydroperoxydammar-23-en-3a,20-diol (4), respectively. The compounds were analyzed using a combination of spectroscopic techniques, including HRMS (high-resolution mass spectroscopy), FTIR (fourier transform infrared spectroscopy), and NMR (nuclear magnetic resonance, one and two dimensional). Cytotoxicity assays using the MTT method were applied to compounds 1-4. All isolated compounds (1-4) generated moderate cytotoxic activity against P388 murine leukemia cells with IC50 9.09, 11.03, 5.89, and 5.74 μg/mL, respectively. Preliminary structure-activity relationship (SAR) analysis suggested that the presence of hydroxyl and hydroperoxyl groups at C-25 increases cytotoxicity, whereas the cyclization in the side chain to form an epoxide ring decreases cytotoxicity.

Abstract

Xylapeptide A, derived from the fungus Xylaria sp. x Sophora tonkinensis, exhibits potent and selective antimicrobial properties. Our research group has successfully synthesized xylapeptide A. In our recent work, two xylapeptide A analogues (An1 and An2) were synthesized using a combination of solid- and solution-phase synthesis methods. The linear precursors of An1 and An2 were synthesized on 2-CTC resin with the Fmoc strategy. The coupling reagents HBTU/HOBt and HATU/HOAt were employed. Subsequently, the linear precursor was cleaved from the resin using either 20% TFA or a TFE mixture, and then cyclized in solution phase with HBTU. The synthesized products were purified using semi-preparative RP-HPLC, giving the percent yields 16% for An1 and 12% for An2. Both compounds were then characterized by HR-ToF-MS, 1H- and 13C-NMR. The synthesized xylapeptide A and its analogues were evaluated against Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, and Candida albicans. The result showed that An2, possessing arginine residue, exhibited higher activity compared to xylapeptide A and An1. This research suggests that xylapeptide A analogues hold great promise as novel antimicrobial agents.

Abstract

Phenolic compounds are a major type of secondary metabolite found in plants. These compounds are synthesized through shikimic and phenylpropanoid pathways, resulting in the formation of numerous unique structures and bioactivities. In addition, a significant amount has been reported in nutmeg, an endemic plant of Indonesia, which has been widely used in traditional medicine. A previous study also revealed that ethyl acetate extract of the plant has notable cytotoxic effects against melanoma B16-F10. Therefore, the purpose of this study is to isolate and evaluate phenolic compounds in nutmeg for their potential to inhibit B16-F10 melanoma cancer cell growth. The seeds extract of nutmeg was separated by various chromatographic techniques to yield a total of five compounds, which were identified through spectroscopic analysis (HR-TOF-ESI-MS, IR, and NMR) as well as comparison with literature. The compounds 1-5 were identified as (+)-veraguensin (1), 3',4',5'-trimethoxycinnamyl alcohol (2), (+)-galbegin (3), (-)-polysphorin (4), and 7-methoxycoumarin (5). Cytotoxic effects were then assayed against B16-F10 melanoma cell lines using the Resazurin method. Furthermore, compound 1 displayed the highest cytotoxic activity, with an IC50 value of 112.71 µM.
