Abstract

The Aglaia species, which contains triterpenoids, is the most numerous in the Meliaceae family. The A. cucullata species, of which there are only a few known examples, has received scant research attention. This investigation aims to identify triterpenoids in an n-hexane preparation of A. cucullata stem bark and evaluate their effects against the A549 lung cancer cell line. Five dammarane-type triterpenoids were isolated from the A. cucullata trunk bark, which is (1) (20S)-20-hydroxydammar-24-en-3-one, (2) cabraleone, (3) cabralealactone, (4) eichlerianic acid, and (5) (+)-fouquierol. Their chemical structures were determined using infrared, high-resolution mass spectrometry, and nuclear magnetic resonance, as well as through data comparison of the reported compounds. Compound 1 was priorly separated from the Aglaia genus, compounds 2–4 were first isolated from the A. cucullata species, and compound 5 has been reportedly isolated from the Meliaceae family and the Aglaia genus. All substances were tested for their lethal potential against the A549 lung cancer cell type. A seco structure in the A ring of dammarane-type triterpenoid might play an important part in the lethal activity of component 4, which showed the greatest activity with an IC50 value of 32.17 µM against the A549 lung cancer cell line.

Masyarakat secara tradisional memanfaatkan tanaman ini sebagai sumber pewarna dan obat tradisional. R. stylosa juga terbukti mengandung zat bioaktif dan metabolit sekunder yang memiliki nilai penting bagi manusia dan organisme lain. Tujuan dari penelitian ini adalah untuk menguji tingkat sitotoksisitas dan genotoksisitas senyawa metabolit sekunder dalam fraksi-fraksi ekstrak etanol R. stylosa terhadap akar dan kromosom tanaman bawang Allium cepa. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL), melibatkan sebelas fraksi dengan konsentrasi seragam (125 ppm), serta kontrol negatif berupa larutan akuades dan kontrol positif berupa larutan EMS, dengan dilakukan sebanyak 3 kali pengulangan. Parameter yang diobservasi meliputi indeks mitosis, pertumbuhan akar bawang, dan aberasi kromosom. Hasil pengamatan dianalisis menggunakan ANOVA Ft(α.05) dan uji lanjutan Duncan Ft (α.05). Hasil pengujian sebelas fraksi dengan konsentrasi 125 ppm menunjukkan penurunan nilai indeks mitosis yang bervariasi, serta terdeteksi adanya aberasi kromosom dengan frekuensi yang beragam. Meskipun demikian, sebelas fraksi tidak menunjukkan sifat subletal maupun letal terhadap indeks mitosis. Jenis aberasi kromosom yang teramati meliputi anaphase spindle break, ball metaphase, break, bridge, c-mitosis, delayed anaphase, diagonal anaphase, disorder of chromosome kinetic, double bridge, double lesion, fragment, giant cell showing polyploidy, laggard, micronucleus, nuclear erosion, nuclear extrusion, ring, star, stickiness, dan vagrant. Rhizopora stylosa (red mangrove) is one species of mangrove that is easily found in large quantities in Indonesia. This plant is widely used traditionally by the community as dyes and herbal medicine. R. stylosa is also known to contain valuable bioactive substances and secondary metabolites for humans and other organisms. This study aims to examine the cytotoxicity and genotoxicity of secondary metabolite compounds from fractions of R. stylosa ethanolic leaf extract on the roots and chromosomes of A. cepa onions. The study was conducted using an experimental method with a Completely Randomized Design (CRD), the treatment of eleven fractions with one 125 ppm for all fractions, and negative control of distilled water solution and positive control of EMS solution, with 3 repetitions for each treatment. The parameters observed were mitotic index, onion root growth and chromosomal aberration. The observations were analyzed with ANAVA Ft (α.05) and followed by Duncan Ft test (α.05). The results of eleven fractions with a concentration of 125 ppm showed a decrease in the value of various mitotic indices and the discovery of chromosome aberrations with varying frequencies. However, eleven fractions did not show a sub-lethal or lethal effect onf the mitotic index. Among the types of chromosomal aberrations observed were anaphase spindle break, ball metaphase, break, bridge, c-mitosis, delayed anaphase, diagonal anaphase, disorder of chromosome kinetic, double bridge, double lesion, fragment, giant cell showing polyploidy, laggard, micronucleus, nuclear erosion, nuclear extrusion, ring, star, stickiness, and vagrant.

Abstract

Chisocheton is a plant of the Meliaceae family which has been known as a source of limonoids, triterpenoids, steroids, alkaloids and phenolics. This plant is the second largest in the Meliaceae, with 53 species widely distributed in tropical and subtropical regions including Indonesia. From this genus, compounds that have interesting activities have been found, including anti-inflammatory, antimalarial, cytotoxic, antitumor and anticancer. One of the species that has the potential to find new compounds is Chisocheton lasiocarpus because there are still few phytochemical studies. This study aims to inform the structural elucidation of one of the compounds from the stem bark of C. lasiocarpus, namely morelloflavone and its cytotoxic potential against breast cancer cells using the in silico method against ER-α receptors (PDB code: 3ERD), ER-β (PDB code: 1QKM). ) and HER-2 (GDP code: 3PP0).

Sesquiterpenoids belong to a group of terpenoid compounds with interesting structures that are abundant in natural products especially in higher plants. Sesquiterpenoids have a wide variety of bioactivities with great potential cytotoxic activity. The species Dysoxylum excelsum belongs to the Meliaceae family known as higher plant, but only a few sesquiterpenoids have been reported particularly for their cytotoxic activity. Therefore, this research aims to isolate and elucidate the sesquiterpenoids structure from D. excelsum stem bark and examines their cytotoxicity against HeLa cervical cancer cells. Through various column chromatography separations, four known sesquiterpenes namely β-caryophyllene oxide (1), caryophyllenol II (2), humulene dioxide A (3), and guai-6-en-10β-ol (4) were acquired from the n-hexane extract. Compounds 1-4 were isolated for the first time from D. excelsum species. The sesquiterpenoid structures were elucidated according to Nuclear Magnetic Resonance, Infrared, and HR-TOF-MS analysis. The cytotoxicity compounds 1-4 was determined against HeLa cervical cancer cells by examination with the PrestoBlue method and compound 3 exhibited the most potent cytotoxicity with an IC50 value of 160.74 µM. Keywords: cytotoxic activity, Dysoxylum excelsum, HeLa, Meliaceae, sesquiterpenoid.

Abstract

ABSTRACT. Limonoid group belongs to triterpenoid that has undergone further oxidation accompanied by the loss of four carbon atoms to form a furan ring in the chain. This limonoid compound is often found in the Chisocheton genus. Limonoid compounds have been known as compounds with high structural variations and this makes limonoids have diverse and interesting activities, including cytotoxic and anticancer. In the course of our continuing study for limonoid constituents that have cytotoxic activity against cancer cell lines, methanol extract of stem bark from the Chisocheton pentandrus plant provides significant activity. The methanol extract was separated using various chromatographic techniques in the normal and reverse stationary phase to produce four azadirone-type limonoid compounds (1-4). The elucidation structure of 1-4 was determined using spectroscopic methods including, UV-Visible, IR, and 1D-NMR as well as optical rotation. All four known compounds were established as trichilenone acetate (1), toonaciliaton C (2), 11α-acetoxiazadiron (3), and 16β-hydroxydisobinine (4). The cytotoxicity of compounds 1-4 was assessed by examination using the resazurin method, which showed that compound 4 was the promising constituent against the MCF-7 cells with an IC50 value of 43.1 µM and was stronger than its positive control. Keywords: Azadirone-type limonoid, Chisocheton pentandrus, cytotoxic activity, Meliaceae.
