Abstract
The insulin-like signaling (IIS) pathway is essential for insect growth and development. In this study, we showed that eurycomanone (EN) is an active compound with growth inhibitory activity against Spodoptera frugiperda larvae. Experiments in cells and RNA-seq analysis in the midgut showed that EN targeted the IIS pathway in S. frugiperda to activate the transcription factor SfFoxO (S. frugiperda forkhead boxO) to regulate mRNA levels associated with nutrient catabolism. Additionally, mass spectrometry imaging revealed that EN was distributed in the larval gut and enriched in the inner membrane of the gut. Immunofluorescence, western blotting, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) results showed that EN induced program cell death (PCD) in the larvae midgut. Thus, EN targeted the insulin receptor to inhibit the IIS signaling pathway, exerting inhibitory activity on the growth and development of S. frugiperda larvae. Our results suggest that EN has great potential as a botanical pesticide, and the IIS signaling pathway may be an effective target for botanical pesticides.

Abstract
Plant-originated triterpenes are important insecticidal molecules. Research on the insecticidal activity of molecules from Meliaceae plants has always been a hotspot due to the molecules from this family showing a variety of insecticidal activities with diverse mechanisms of action. In this paper, we discussed 116 triterpenoid molecules with insecticidal activity from 22 plant species of five genera (Cipadessa, Entandrophragma, Guarea, Khaya, and Melia) in Meliaceae. In these genera, the insecticidal activities of plants from Entandrophragma and Melia have attracted substantial research attention in recent years. Specifically, the insecticidal activities of plants from Melia have been systemically studied for several decades. In total, the 116 insecticidal chemicals consisted of 34 ring-intact limonoids, 31 ring-seco limonoids, 48 rearranged limonoids, and 3 tetracyclic triterpenes. Furthermore, the 34 ring-intact limonoids included 29 trichilin-class chemicals, 3 azadirone-class chemicals, and 1 cedrelone-class and 1 havanensin-class limonoid. The 31 ring-seco limonoids consisted of 16 C-seco group chemicals, 8 B,D-seco group chemicals, 4 A,B-seco group chemicals, and 3 D-seco group chemicals. Furthermore, among the 48 rearranged limonoids, 46 were 2,30-linkage group chemicals and 2 were 10,11-linkage group chemicals. Specifically, the 46 chemicals belonging to the 2,30-linkage group could be subdivided into 24 mexicanolide-class chemicals and 22 phragmalin-class chemicals. Additionally, the three tetracyclic triterpenes were three protolimonoids. To sum up, 80 chemicals isolated from 19 plant species exhibited antifeedant activity toward 14 insect species; 18 chemicals isolated from 17 plant species exhibited poisonous activity toward 10 insect species; 16 chemicals isolated from 11 plant species possessed growth-regulatory activity toward 8 insect species. In particular, toosendanin was the most effective antifeedant and insect growth-regulatory agent. The antifeedant activity of toosendanin was significant. Owing to its high effect, toosendanin has been commercially applied. Three other molecules, 1,3-dicinnamoyl-11-hydroxymeliacarpin, 1-cinnamoyl-3-methacryl-11-hydroxymeliacarpin, and 1-cinnamoyl-3-acetyl-11-hydroxymeliacarpin, isolated from Meliaazedarach, exhibited a highly poisonous effect on Spodoptera littoralis; thus, they deserve further attention.

Abstract
Unlike faster-acting conventional insecticides, some botanical insecticides exhibit growth inhibitory activity against some insect pests. One of the distinguishing features of growth inhibitory activity appears to be in malformed moths with vestigial wings. However, the molecular mechanism underlying vestigial wings of insect pests induced by plant natural products or their derivatives is still elusive. In this work, based upon the phenotype of the vestigial wings of Mythimna separata Walker (as a model pest) induced by a podophyllotoxin derivative 2a (as a model compound), we found that compound 2a not only resulted in 22.1% of malformed moths with vestigial wings but also significantly decreased the fecundity of vestigial-winged female moths in the P generation; the trait of vestigial wings caused by 2a in the P generation can be inherited by the F1 generation; compound 2a may target insulin receptor 1 (InR1), suppress the InR1 mRNA level, and block InR1-pY1229 and InR1-pY1233/1234 phosphorylation levels in a tissue-specific manner "head/thorax/wing tissues". Notably, compound 2a can also induce the vestigial wings of Spodoptera frugiperda (another seriously harmful migratory lepidoptera pest). It is noteworthy that this insect insulin receptor can be used as a new kind of target receptors for the design of novel green insecticides.

Abstract
Limonoids, as the vital bioactive chemical compounds in genus Melia plants, have attracted significant attention owing to their exclusive structural characteristics and remarkable biological activity. These compounds can be usually classified into two categories, including the ring-intact group and the ring-C-seco group. Benefiting from the development of separation and analysis technology, more than 200 limonoids have been isolated and identified from this genus. There is growing evidence that limonoids from genus Melia possess diverse pharmacological activities, especially anti-cancer effects, insecticidal activities, and anti-botulism effects. Toosendanin, one of the paramount limonoids, was considered as the pivotal bioactive marker in two medicinal herbs, including Melia toosendan Sieb. et Zucc and Melia azedarach L. In particular, limonoids are found to exhibit non-negligible toxic effects, a finding which needs further research. Besides this, the lack of clinical research data seriously hinders its further development and utilization, and necessary clinical trials should be taken into consideration. In this review, we systematically summarized the phytochemical compounds and their synthesis methods, pharmacological activities, and the structure–activity relationship, pharmacokinetics, and toxicology of genus Melia-derived limonoids. We believe that this up-to-date review could provide scientific evidence for the application of limonoids as agents beneficial to health in future clinical practice.

Abstract
Globally, the citrus industry produces various wastes, which contain a great deal of limonoids. In order for the sustainable development of the citrus industry, and considering the diverse bioactivities of limonoids, a series of ester derivatives were constructed by structural modification of limonin in the B ring. Furthermore, two seven-membered lactone derivatives of limonin and obacunone with a novel skeleton in the B ring were obtained by the Baeyer-Villiger oxidation rearrangement. The steric structures of six key compounds 3a, 3b, 4m, 4n, 6, and 7 were determined by X-ray crystallography. It demonstrated that the molar ratio of 3a (7α-isomer) and 3b (7β-isomer) depended on the mixed solvents in the reduction system. The anti-tobacco mosaic virus (TMV) activities under three different modes of action for most of the tested compounds were as the following sequence: inactivation effect > protection effect > curative effect. It was noteworthy that compound 4aa displayed the most potent anti-TMV/insect growth inhibitory activities, which indicated that the introduction of the phenylacryloyloxy group at the C-7β position of limonin could significantly improve its agricultural biological activities. This study will pave the way for future value-added application of citrus industrial wastes and provide strong evidence for the discovery of sustainable biopesticides based on limonoids.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 58:152867. [PMID: 30844585 DOI: 10.1016/j.phymed.2019.152867] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 01/26/2019] [Accepted: 02/17/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Toosendan Fructus is traditionally used as an insecticide or digestive tract parasiticide for treating digestive parasites in China. It is recorded to have little toxicity in Chinese Pharmacopoeia and has been found to cause severe liver injury during clinical practice. PURPOSE This study aims to identify candidate serum microRNAs (miRNAs) as potential toxicological biomarkers for reflecting the hepatotoxicity induced by toosendanin (TSN), which is the main toxic compound isolated from Toosendan Fructus METHODS: Alanine/aspartate aminotransferase (ALT/AST) activities detection and liver histological observation were performed to evaluate the liver injury induced by TSN or other hepatotoxicants in mice. miRNAs chip analysis and Real-time PCR assay were conducted to identify the altered miRNAs in serum from TSN-treated mice RESULTS: The results of serum ALT/AST and liver histological evaluation showed that TSN (10 mg/kg) induced hepatotoxicity in mice. The results of miRNAs chip showed that the expression of 81 serum miRNAs was obviously altered in mice treated with TSN for 12 h, and 22 of them have passed the further validation in serum from mice treated with TSN for both 6 h and 12 h. These 22 miRNAs were supposed to be the candidate toxicological biomarkers for TSN-induced hepatotoxicity with more sensitivity as compared to the alteration of AST or ALT activity. Moreover, the expression of miRNA-122-3p and mcmv-miRNA-m01-4-3p was not only increased in TSN-treated mice, but also increased in mice treated with other hepatotoxicants including acetaminophen (APAP), monocrotaline (MCT) and diosbuibin B (DB). Only the expression of serum miRNA-367-3p was increased in TSN-treated mice but not changed in the liver injury induced by APAP, MCT or DB CONCLUSION: miR-122-3p and mcmv-miRNA-m01-4-3p may be two commonly sensitive biomarkers for reflecting the hepatotoxicity induced by exogenous hepatotoxicants, and miR-367-3p may be a specific biomarker for reflecting the liver injury induced by TSN.

Quercetin attenuates toosendanin-induced hepatotoxicity through inducing the Nrf2/GCL/GSH antioxidant signaling pathway. Acta Pharmacol Sin 2019; 40:75-85.

Abstract
Toosendanin (TSN) is the main active compound in Toosendan Fructus and Meliae Cortex, two commonly used traditional Chinese medicines. TSN has been reported to induce hepatotoxicity, but its mechanism remains unclear. In this study, we demonstrated the critical role of nuclear factor erythroid 2-related factor 2 (Nrf2) in protecting against TSN-induced hepatotoxicity in mice and human normal liver L-02 cells. In mice, administration of TSN (10 mg/kg)-induced acute liver injury evidenced by increased serum alanine/aspartate aminotransferase (ALT/AST) and alkaline phosphatase (ALP) activities, and total bilirubin (TBiL) content as well as the histological changes. Furthermore, TSN markedly increased liver reactive oxygen species (ROS) and malondialdehyde (MDA) levels, and decreased liver glutathione (GSH) content and Nrf2 expression. In L-02 cells, TSN (2 μM) time-dependently reduced glutamate-cysteine ligase (GCL) activity and cellular expression of the catalytic/modify subunit of GCL (GCLC/GCLM). Moreover, TSN reduced cellular GSH content and the increased ROS formation, and time-dependently decreased Nrf2 expression and increased the expression of the Nrf2 inhibitor protein kelch-like ECH-associated protein-1 (Keap1). Pre-administration of quercetin (40, 80 mg/kg) effectively inhibited TSN-induced liver oxidative injury and reversed the decreased expression of Nrf2 and GCLC/GCLM in vivo and in vitro. In addition, the quercetin-provided protection against TSN-induced hepatotoxicity was diminished in Nrf2 knock-out mice. In conclusion, TSN decreases cellular GSH content by reducing Nrf2-mediated GCLC/GCLM expression via decreasing Nrf2 expression. Quercetin attenuates TSN-induced hepatotoxicity by inducing the Nrf2/GCL/GSH antioxidant signaling pathway. This study implies that inducing Nrf2 activation may be an effective strategy to prevent TSN-induced hepatotoxicity.

Abstract
The title limonoid compound, C26H28O5·0.5H2O (TS3) [systematic name: (3aS,3bS,4aS,5aS,6S,7aR,8aR,8bS,11aR)-6-(furan-3-yl)-3a,5a,8b,11a-tetra-methyl-3a,4a,5,5a,6,7,7a,8b,11,11a-deca-hydro-oxireno[2',3':4b,5]oxireno[2'',3'':2',3']cyclo-penta-[1',2':7,8]phenanthro[10,1-bc]furan-3(3aH)-one hemihydrate], crystallizes with two independent mol-ecules (1 and 2) in the asymmetric unit and one water mol-ecule. TS3 is composed of three six-membered rings (A, C and D), three five-membered rings (B, E and F) and two epoxide rings. A group of five fused rings (A-E) is bonded to a furan ring (F) with a Csp3-Csp2 bond [1.500 (3) Å in mol-ecule 1 and 1.499 (3) Å in mol-ecule 2]. The absolute structures of the mol-ecules in the crystal were determined by resonant scattering; Flack parameter = 0.05 (5). In the crystal, the individual mol-ecules stack in columns along the b-axis direction. The water mol-ecule bridges mol-ecules 1 and 2 via Owater-H⋯O and C-H⋯Owater hydrogen bonds. Together with further C-H⋯O hydrogen bonds, linking mol-ecules 1 and 2, the columns are linked to form slabs parallel to the ab plane. Within each column, mol-ecules are also linked via C-H⋯π inter-actions involving the five-membered furan (F) rings.

Abstract
Eight new aphanamixoid-type aphanamixoids (C-J, 1-8) and six new prieurianin-type limonoids, aphanamixoids K-P (9-14), along with 10 known terpenoids were isolated from Aphanamixis polystachya, and their structures were established by spectroscopic data analysis. Among the new limonoids, 13 compounds exhibited antifeedant activity against the generalist Helicoverpa armigera, a plant-feeding insect, at various concentration levels. In particular, compounds 1, 4, and 5 showed potent activities with EC50 values of 0.017, 0.008, and 0.012 μmol/cm(2), respectively. On the basis of a preliminary structure-activity relationship analysis, some potential active sites in the aphanamixoid-type limonoid molecules are proposed.
