Abstract

Dysoxylum alliaceum belongs to the Dysoxylum genus (Meliaceae) and there are few reports concerning the phytochemical components of this plant. To examine the chemical constituents of Dysoxylum alliaceum stem bark, a phytochemical study has been conducted and identified five known steroids, 3β,16β-dihydroxy-24(S)-methyl cholestenol (1), ergosta-5,22-dien-3β-ol (2), ergosta-7,24(28)-dien-3β-ol (3), 22(E)-ergosta-6,22-dien-3β,5α,8α-triol (4), and 20α-dihydroprogesterone (5) from its ethanolic extract. Spectroscopic data such as FT-IR, HR-ESI-MS, 1D, and 2D NMR as well as comparison with previously published spectral data were used to identify the chemical structures of compounds 1–5. Furthermore, these steroids 1-5 were assessed in vitro regarding their cytotoxic effect against A549 lung cancer cell lines and revealed weak to inactive with IC50 values ranging from 68.52 to >150 µM.

Abstract

Damping off disease caused by Sclerotium rolfsii is one of the important diseases of soybean plants. Biocontrol is considered as more environmentally friendly control method. Yeast is one of the biocontrol agents that can be used to control plant pathogens. This study was objected to test the potential of three species of yeast in inhibiting the growth of S. rolfsii. The experiment was arranged in the completely randomized design. The treatments were dual culture of the pathogen vs the yeasts on PDA and double dishes of S. rolfsii against three yeast isolates i.e. Rhodotorula minuta Dmg 16 BEP, Candida tropicalis Lm 13 BE, Aureobasidium pullulans Dmg 11 DEP, and a control. The results of the dual culture antagonism test showed that the three tested yeasts could inhibit the colony diameter of S. rolfsii by 23.30% – 40.00%, and the sclerotia formation by 46,33% – 98,05%. The results of the double dishes antagonism test showed that the three tested yeast isolates could inhibit the colony diameter of S. rolfsii by 19.60% – 28.20% and could inhibit 100% of sclerotia formation. The treatment of A. pullulans Dmg 11 DEP produced the highest inhibition in both the dual culture and double dishes antagonism tests.

Abstract

Three sesquiterpenoids, guaianediol (1), alismol (2), and spathulenol (3), were isolated from the n-hexane and ethyl acetate extracts of the stem bark of Dysoxylum amooroides. The three compounds were found in D. amooroides species for the first time. The structures of the isolated compounds were identified and established based on an extensive spectroscopic analysis involving HR-TOF-ESI-MS, IR, and NMR data, as well as a comparison with the previously reported works of literature. Compounds 1-3 were further assessed for cytotoxic effects against MCF-7 breast cancer cells. Guaianediol (1) showed inactive activity with IC50 > 100 µM, alismol (2) showed weak activity with IC50 value of 82.1 µM and spathulenol (3) showed considerable activity with an IC50 value of 15.2 µM. A brief structure-activity relationship and comparison with the previous works were also discussed to understand better the role of guaiane- and aromadendrane-type sesquiterpenoids in the biological activity perspective.

Abstract

Gynura procumbens is a diuretic plant that has been used traditionally to cure kidney stones. In order to determine the calcium levels in the rats' kidneys, the anti-nephrolithiasis activity of male white rats was tested in this study.This research method was carried out experimentally in a laboratory which included sampling, plant identification, making simplicia, making ethanol extract of sambung nyawa leaves, characteristics of simplicia, phytochemical screening, administering animal test preparations, then the data was analyzed using the Anova test. Oral administration of succulent leaf extract is done at three different doses: 50, 100, and 200 mg/kg bw. A positive control is provided with Batugin elixir, which is 0.54 mL/125 g BW and induced at a volume of 7.5 mL/125 g BW/day using ethylene glycol 0.75% and ammonium chloride 2%. The study's findings demonstrated that, with a kidney stone inhibitor percentage of 31.71%, the ethanol extract of Sambung Nyawa leaves at a dose of 200 mg/kg BW was more successful in preventing the formation of kidney stones than doses of 50 mg/kg BW and 100 mg/kg BW. This proves that the ethanol extract from Sambung Nyawa leaves can be an alternative way to prevent kidney stones. The conclusion is that the ethanol extract of Gynura procumbens L. leaves has antinephrolithiasis activity in male white rats, especially at a dose of 200 mg/kg BW. It also reduced calcium oxalate levels in mice induced by ethylene glycol and ammonium chloride.

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

A total of three tirucallane-type triterpenoids were successfully isolated from the n-hexane extract of the stem bark of Dysoxylum gaudichaudianum: 4,4,14-trimethyl-3-oxo-24-nor-5α,13α,14β,17α,20S-chol-7-en-23-oic (1), toonapubesin B (2), and 3β,22S-dihydroxy-tirucalla-7,24-dien-23-one (3). These compounds were isolated from D. gaudichaudianum for the first time. Structural characterization of the isolated compounds was accomplished through a series of spectroscopic analyses, including HR-TOF-MS, IR, and NMR. Based on previous reports, compound 1 was isolated from a member of the Meliaceae family for the first time. The cytotoxic properties of the isolated tirucallane-type triterpenoids were evaluated against cervical HeLa cancer cells. Among them, compounds 1 and 3 were inactive, with IC50 values > 100 µM, while compound 2 exhibited the highest cytotoxicity, with an IC50 value of 29.23 µM, with moderate activity. A structure–activity relationship also indicated the variation in cytotoxicity attributed to substituent effects within the molecular structures. The modification of the side chain in tirucallane-type triterpenoids was shown to be essential for their cytotoxic activity against human cervical cancer lines.

Abstract

ABSTRACT. The exploration of naturally occurring secondary metabolites from plants, which serve as direct sources or precursors for new drug development, motivates us to conduct a comprehensive investigation into their presence. Indonesia stands out as a global biodiversity hotspot, boasting a significant number of endemic species that offer a rich reservoir of untapped resources for pharmaceutical, agricultural, and environmental uses. The Dysoxylum genus, belonging to the Meliaceae family, is recognized as a vital source of secondary metabolites and is well-known for its traditional medicinal applications. Consequently, we focus on analyzing the chemical constituents found in the stem bark of one Indonesian Dysoxylum species, specifically D. parasiticum (Osbeck) Kosterm., and assess their biological activity as anticytotoxic agents. Our research identified three known compounds: a tirucallane-type triterpenoid, cneorin-NP36 (1), a seco-limonoid from the preurianin group, amotsangin A (2), and an ergostane-type steroid, 22(E)-ergosta-6,22-dien-3β,5α,8α-triol (3). The biological evaluation against the human breast cancer cell line MCF-7 revealed that compound 2 exhibited a notable inhibitory effect, with an IC50 value of 34.5 μM. The existence of a highly oxidized structure in compound 2, due to its ester substituents, highlights its effectiveness in inhibiting cancer cell proliferation, outperforming the reference drug cisplatin, which has an IC50 of 53.0 μM. These findings indicate that amotsangin A (2) is a promising anticancer agent, particularly in the treatment of breast cancer. Further studies, including in silico analysis and structural modification, are needed to enhance its cytotoxic activity and selectivity.

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.
