Abstract
Four new mexicanolide-type limonoids, swietemicrolides A-D (1-4), together with three known compounds (5-7) were isolated from an ethyl acetate extract of the bark of Swietenia microphylla. 1 and 2 had 1,8-hemiacetal systems whilst 3 and 4 shared hexacyclic skeletons consisting of three fused five-membered rings. The structures of the isolated compounds were determined using spectroscopic methods. The five limonoids (1-5) were tested in vitro for their cytotoxic effects against two human cancer cell lines (KB carcinoma and A549 lung cancer cells) and α-glucosidase inhibitory activity. None of them showed significant cytotoxic activity, however, swietemicrolide C (3) exhibited strong effect towards α-glucosidase. Moreover, a possible biosynthetic pathway for compounds 1-4 was proposed to support a comprehensive understanding of the configurations of the new limonoids.

Abstract
A total of five new mexicanolides (1-5), namely alliaxylines A-E, together with two known limonoids 6 and 7, were isolated and identified from Dysoxylum alliaceum (Blume) Blume ex. A.Juss. (Meliaceae). The structures of these compounds were elucidated based on extensive spectroscopic analyses, including HR-ESI-MS, UV, IR, 1D, and 2D NMR, as well as theoretical stimulation of NMR shifts with the DP4 + algorithm. Consequently, this study aimed to examine cytotoxic activities of these compounds against MCF-7 and A549 cell lines. The results implied that compound 2 was the most potent against the two tested cells, with IC50 values of 34.95 ± 0.21 and 44.39 ± 1.03 µM.

Abstract
Nine new limonoids (1-9) were isolated from the stem bark of Guarea guidonia (1-4) and Cedrela odorata (5-9). Their structures were elucidated using 1D and 2D NMR and MS data and chemical methods as three A2,B,D-seco-type limonoids (1-3), a mexicanolide (4), three nomilin-type (5-7) limonoids, and two limonol derivatives (8 and 9). A DFT/NMR procedure was used to define the relative configurations of 1 and 3. A surface plasmon resonance approach was used to screen the Hsp90 binding capability of the limonoids, and the A2,B,D-seco-type limonoid 8-hydro-(8S*,9S*)-dihydroxy-14,15-en-chisomicine A, named chisomicine D (1), demonstrated the highest affinity. By means of mass spectrometry data, biochemical and cellular assays, and molecular docking, 1 was found as a type of client-selective Hsp90 inhibitor binding to the C-terminus domain of the chaperone.

Abstract
BACKGROUND Natural resources provide more efficient and safer alternatives in managing diabetes compare to the synthetic oral anti diabetes (OAD). The plants not only have hypoglycemic effect, but also prevent its complications; in which no synthetic drugs provide of both properties. Among antidiabetes plants, mahogany seed (Swietenia macrophylla) has been used as traditional medicine in Indonesia and India, though most popular utilized as timber wood. METHODS The present study was performed of chemotaxonomic approach to review its phytochemical and anti-diabetic properties of Swietenia mahagoni (L.) Jacq seed/bark/leaves. The qualitative systematic review (SR) was carried out by analysing indexed journals and peer reviewed of Swietenia and Swietenia spp from Scopus, PubMed, Medline, Google Scholar, and Research Gate. Data selection criteria are accordance to botany, phytochemistry, in vitro, in vivo, and clinical test of related subject. The keywords used for the search in the databases were Swietenia, Swietenia mahagony, diabetes, and diabetes plants. RESULTS Swietenia mahagoni (L.) Jacq. extracts have shown in vitro, in vivo and limited clinically test of its anti-diabetic properties. Ethanolic/methanolic/aqueous/petroleum/n-hexane extracts of mahagonis's seed/bark or leaves have anti-diabetic activities comparable to the synthetic drug and observed no to relatively mild toxic effect. The hypoglycemic mechanism suggested via reducing blood glucose level, restoring liver and β-cells islet function (might) blocking epinephrine function, inhibiting of α-amylase and β-glucosidase, antioxidant and antihiperlipidemia. Phytochemical compounds of S. mahagoni consist of the phenolics (flavonoids (swietemacrophyllanin, catechins and epichatechins) and tannins), triterpenoids and tetranortriterpenoids (limonoids: mahonin, secomahoganin, swietmanins, swiemahogins, swietenine and swietenolide), saponins and alkaloids which are known as anti-diabetic bioactive principles. CONCLUSION S. mahagoni was potentially used and developed as an antidiabetes source. To use it as an antidiabetic further, more extensive clinical trials and biomarkers of active compounds determination are needed.

Abstract
Twenty-nine new limonoids—named xylomolins A1–A7, B1–B2, C1–C2, D–F, G1–G5, H–I, J1–J2, K1–K2, L1–L2, and M–N, were isolated from the seeds of the mangrove plant, Xylocarpus moluccensis. Compounds 1–13 are mexicanolides with one double bond or two conjugated double bonds, while 14 belongs to a small group of mexicanolides with an oxygen bridge between C1 and C8. Compounds 15–19 are khayanolides containing a Δ8,14 double bond, whereas 20 and 21 are rare khayanolides containing a Δ14,15 double bond and Δ8,9, Δ14,15 conjugated double bonds, respectively. Compounds 22 and 23 are unusual limonoids possessing a (Z)-bicyclo[5.2.1]dec-3-en-8-one motif, while 24 and 25 are 30-ketophragmalins with Δ8,9, Δ14,15 conjugated double bonds. Compounds 26 and 27 are phragmalin 8,9,30-ortho esters, whereas 28 and 29 are azadirone and andirobin derivatives, respectively. The structures of these compounds, including absolute configurations of 15–19, 21–23, and 26, were established by HRESIMS, extensive 1D and 2D NMR investigations, and the comparison of experimental electronic circular dichroism (ECD) spectra. The absolute configuration of 1 was unequivocally established by single-crystal X-ray diffraction analysis, obtained with Cu Kα radiation. The diverse cyclization patterns of 1–29 reveal the strong flexibility of skeletal plasticity in the limonoid biosynthesis of X. moluccensis. Compound 23 exhibited weak antitumor activity against human triple-negative breast MD-MBA-231 cancer cells with an IC50 value of 37.7 μM. Anti-HIV activities of 1, 3, 8, 10, 11, 14, 20, 23–25, and 27 were tested in vitro. However, no compounds showed potent inhibitory activity.

Abstract
We report the first total synthesis of the limonoid andirolide N using a 12-step sequence from commercially available materials. The final step of this route demonstrates the chemical feasibility of our biosynthetic proposal that andirolide N arises from 8α-hydroxycarapin. The strategic use of a degraded limonoid as a platform for the synthesis of more structurally complex congeners may be a general approach to obtain limonoids with diverse functional properties.

Abstract
The usage of Swietenia mahagoni, a popular medicinal plant in India and some African countries, dates back to ancient times for its curative properties in diseases like malaria, diabetes, and diarrhea. It is also used as an anti-pyretic, bitter tonic and astringent. Its pharmacological activities are being widely explored. Although many important groups of phytochemicals have been identified and isolated from various parts of the plant, most of these researches have been focused on seeds. Toxicological studies have established the safety of many of these plant extracts, and found insignificant side effects. Here we present a comprehensive review of all the pharmacological effects and constituent phytochemicals of the plant.

Abstract
Limonoids are heavily oxygenated, modified triterpenes dominant in Meliaceae and Rutaceae plant families. The term 'limonoid' is derived from limonin, which was first identified as the bitter constituent of Citrus seeds in 1841. This group of secondary metabolites exhibits a wide range of biological properties, including anticancer, antibacterial, antifungal, antimalarial, and antiviral activities. Significant progress on the role of limonoids as promising candidates for cancer chemoprevention and/or therapy has been achieved in particular in recent years. The aim of this review article is to discuss the recent developments on limonoids chemical aspects and biological activities with the relationship between structure and activity, supporting the new possibilities for the medicinal and/or nutraceutical use of these compounds.

Abstract
This review describes the major discoveries of structurally diverse and/or biologically significant compounds from plant resources in China, mainly from the traditional Chinese medicines (TCMs) since the establishment of our research group in 1999. In the past decade, a large array of biologically significant and novel structures has been identified from plant resources (or TCM) in our laboratory. The structural modification of several biologically important compounds led to more than 400 derivatives, some of which exhibited significantly improved activities and provided opportunities to elucidate the structure-activity relationship of the related compound class. These findings are important for drug discovery and help us understand the biological basis for the traditional applications of these plants in TCM.

Abstract
Eight limonoids, named moluccensins R-Y (1, 2, 5-10), and six known compounds, including 6-hydroxymexicanolide (3), were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis, collected in the estuaries of Andhra Pradesh. The absolute configuration of moluccensin V (7) was confirmed by means of single-crystal X-ray diffraction analysis. The (1)H and (13)C NMR data for 6-hydroxymexicanolide (3) was assigned for the first time, and the 6R absolute configuration established by single-crystal X-ray diffraction analysis. Moluccensin R (1), 6R-hydroxymexicanolide (3), and 2-hydroxyfissinolide (4) exhibited marked antifeedant activity against the third-instar larvae of Brontispa longissima at a concentration of 1 mg/mL. The most potent compound tested was 2-hydroxyfissinolide (4), with an AFC(50) (concentration for 50% antifeedant activity) value of 94 μg/mL at 24 h.
