Zhao L, Zhang Y, Yin Q, Chen G, Li W, Li N. Research progress on the toxicity of toxic Traditional Herbals from Thymelaeaceae. JOURNAL OF ETHNOPHARMACOLOGY 2024; 322:117594. [PMID: 38110134 DOI: 10.1016/j.jep.2023.117594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/23/2023] [Accepted: 12/12/2023] [Indexed: 12/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants from the Thymelaeaceae family are widely distributed in tropical and temperate regions, with approximately 113 species used as Traditional Herbals. There are numerous applications for them, such as treating leukemia, AIDS, and liver cancer. It should be noted that around 20% of these plants have shown harmful side effects when used in clinical applications, including solid irritations to the skin and mucous membranes, carcinogenic effects, organ damage, vomiting, and diarrhea. AIM OF THE STUDY This paper aims to review the toxic side effects, toxic compounds, toxic mechanisms, and detoxification methods of Traditional Herbals in Thymelaeaceae, guiding their safe clinical uses. MATERIALS AND METHODS This review employed the keywords "Thymelaeaceae," 48 different "genus," 966 "species," and the combination of "toxicity" to identify the medicinal value and toxicity of plants from Thymelaeaceae in scientific databases (Pubmed, SciFinder Scholar, Elsevier, Web of Science, and CNKI). Information relevant to the toxicity of Traditional Herbals from Thymelaeaceae up to June 2023 has been summarized. The plant names have been checked with "World Flora Online" (www.worldfloraonline.org). RESULTS 28 toxic Traditional Herbals from 13 genera within the Thymelaeaceae family were categorized. Toxicities were summarized at the cellular, animal, and clinical levels. The toxic substances are primarily concentrated in the Daphne L. and Wikstroemia Endl. genera, with terpenes being the main toxic components. The toxicity mechanism is primarily associated with the mitochondrial pathways. Detoxification and enhanced efficacy can be achieved through processing methods such as vinegar-processing and sweat-soaking. CONCLUSIONS Medicinal plants in the Thymelaeaceae exhibit significant pharmacological activities, such as anti-HIV and anti-tumor effects, indicating a broad potential for application. However, their clinical uses are hindered by their inherent toxicity. Researching the toxic components and mechanisms of these Traditional Herbals and exploring more effective detoxification methods can contribute to unveiling the latent value of these medicinal plants from Thymelaeaceae.

Abstract
To explore the toxicity mechanisms of neochamaejasmin B (NCB) extracted from Stellera chamaejasme L., we first evaluated its cytotoxicity in neuronal cells of Helicoverpa zea (AW1 cells). NCB inhibited cell growth and was cytotoxic to AW1 cells in a dose-dependent manner. Further, transmission electron microscopy (TEM) was used to analyze the microstructure, and typical apoptotic characteristics were observed in AW1 cells treated with NCB. Moreover, the NCB-induced apoptosis was dose dependent. Subsequently, we explored the mechanism of apoptosis. A decline in the mitochondrial membrane potential (MMP) was found. Also, the levels of Bax were increased with increases in drug concentration, but there was no statistical difference in Bcl-2 levels at different NCB doses. Caspase-3 and caspase-10 activity was increased. These findings confirmed that NCB induced apoptosis in AW1 cells through a caspase-10-dependent mechanism. The results provide the basic information needed for understanding the toxicity and mechanisms of action of NCB, which could potentially be used to develop NCB as a new insecticide.

Abstract
Stellera chamaejasme L. is a Chinese traditional herb. It has a long history and many medicinal usages. Biflavones, one of the main active ingredients in S. chamaejasme's roots, possess excellent insecticidal activities both in vivo and in vitro. However, the mechanism of these compounds and its potential molecular targets on insect cell were still not clear. Here the whole cell patch clamp technique was used to investigate whether biflavones affects voltage-gated potassium channels (Kv) on insect neuronal cells (AW1 and WG2). The results confirmed that both the three biflavones: neochamaejasmin A (NCA), neochamaejasmin B (NCB) and isochamaejasmin A (ICM) can significantly inhibit the A-type potassium current (IA) than delayed rectifier potassium current (IK) expressed on insect cells. Moreover, ICM stood out as the strongest inhibition activity on IA with IC50 value of 106.75 μM. Multiple results suggest that the inhibition of potassium current was related to the gating modification of biflavones. ICM produced concentration dependent hyperpolarizing shifts in the voltage dependence of channel steady-state activation and inactivation. Maximal shifts of the ICM-induced V0.5, were -15.1 mV for activation and -6.93 mV for inactivation. ICM also prolonged recovery from inactivation of current. Moreover, the biflavones could inhibited AW1 cell survival in both dose- and time-dependent manners with well correlation of K+ inhibitory activity. Our study showed that biflavones from S. chamaejasme exhibiting significant blocked effects on Kv of AW1 cells and inhibited cell proliferation. These findings may not only show the toxic mechanisms of biflavones on insect cells, but also suggest that Kv channel play an important role in biflavones' mode of action and may be the new targets for designing novel insecticides.

Abstract
Thirty semicarbazone and thiosemicarbazone derivatives (2a-w and 4a-g) from chalcones containing furan and thiophene ring were designed and synthesized. They were characterized by IR, 1H NMR, 13C NMR and HRMS. The crystal structure of compound 2r was characterized by single crystal X-ray diffraction. It crystallizes in the monoclinic system with space group P21/c. The insecticidal activity of the synthesized compounds was screened against Leucania separata and Pieris rapae using beta-cypermethrin as the comparative standard. The results displayed that most of them had remarkable insecticidal activity. Among them, compounds 2e-g showed better activity than beta-cypermethrin against L. separata and P. rapae. Compound 2p also possessed a better activity than beta-cypermethrin against P. rapae. The insecticidal activities of these compounds have been reported for the first time.

Abstract
BACKGROUND Botanical pesticides increasingly play important roles in the control of agricultural pests. In this study, the aphidicidal effect of moso bamboo (Phyllostachys pubescens) extract against mustard aphid was confirmed, the main active compounds identified, and aphidicidal mechanism of the most active compound established. RESULTS When the treatment concentration was 10.0 g L-1 , the corrected mortality of bamboo leaf extract (BE) was 53.22 ± 5.20% and the petroleum ether component of bamboo leaf extract (PE) reached 82.76 ± 4.50%, which also showed a synergistic effect with imidacloprid. Four flavonoids were identified as the main active components in the BE via activity tracking and phytochemical method. Isoorientin had an LC50 of 313.22 mg L-1 , and affected the activities of acetylcholinesterase and peroxidase significantly, revealing the possible aphidicidal mechanism. When the treatment of 11.1% PE·imidacloprid was 200 mL, the control effect was 99.07%, which was better than that observed with 10% of imidacloprid or 0.5% of matrine. CONCLUSIONS These data provide a better understanding of the aphidicidal activity and aphidicidal mechanism of moso bamboo leaf extract and the most active compound, isoorientin. This will help in developing a more effective botanical aphicide. © 2019 Society of Chemical Industry.

Abstract
To explore the toxicity mechanisms of neochamaejasmin A (NCA), extracted from Stellera chamaejasme L., we first evaluated its cytotoxicity on the Spodoptera frugiperda (Sf9) cell line. The results confirmed that NCA inhibited Sf9 cell survival in both a dose- and time-dependent manner. Then, intracellular biochemical assays showed that NCA induced apoptosis in Sf9 cells. Evidence of apoptosis was confirmed by morphological changes and the activation of caspases-3/9. We also observed that NCA induced apoptosis via mitochondrial-dependent intrinsic apoptotic pathway by upregulating cytochrome c and proapoptotic protein (Bax) and downregulating the mitochondrial membrane potential (MMP) and antiapoptotic protein (Bcl-2). Moreover, we found a dose-dependent increase in reactive oxygen species (ROS), accumulation of lipid peroxidation product and an inactivation of the antioxidant enzymes in treated cells. Additionally, the cleavage of PARP and G2/M arrest were also detected in Sf9 cells exposed to NCA. These findings provide critical information that NCA effectively induced apoptosis in Sf9 cells through mitochondrial pathways.

Abstract
A series of novel 1,5-Diphenyl-2-penten-1-one analogues (7a-h, 8a-h) with piperazine moiety have been designed and synthesized on the basis of natural product 1,5-Diphenyl-2-penten-1-one (I). All the synthesized compounds were evaluated in vitro for anti-plant pathogenic fungi activities and insecticidal activities. The results indicated that most of these analogues exhibited moderate antifungal activities and moderate to good insecticidal activities. Amongst them, the most potent 7c, 7e and 7h keep a mortality of 100% against larva of mosquito at the concentration of 1mg/L. Initial structure-activity relationship (SAR) analysis showed that, a methyl group can influence the biological activities of these compounds significantly, the compounds with N'-unsubstituted piperazine showed much better antifungal activities and larvicidal activity against mosquito than the compounds with N'-methylated piperazine. In addition, the larvicidal activity against mosquito had sharply decline when the substituent on benzene ring was changed from 4-position to 2 or 3-position.

Abstract
BACKGROUND Bursaphelenchus xylophilus, the causal agent of pine wilt disease, severely damages pine forests, and Bursaphelenchus mucronatus, a species related to B. xylophilus, is weakly pathogenic. Because the use of synthetic pesticides to control pine wilt disease has raised concerns for human and environmental health, a search for useful botanically based compounds is needed. RESULTS The ethyl acetate layer from an ethanol extract of Stellera chamaejasme L. roots showed significant nematicidal activity against B. xylophilus and B. mucronatus, with LC50 values of 169.7 and 37.7 µg mL(-1), respectively, at 72 h. Further purification of the active layer yielded eight effective nematicidal compounds, which were identified by mass and nuclear magnetic resonance spectral data. Among the eight bioactive compounds, chamaejasmenin C induced the highest mortality against B. xylophilus, with an LC50 value of 2.7 µM at 72 h, and chamaechromone exhibited strong nematicidal activity against B. mucronatus, with an LC50 value of 0.003 µM at 72 h. CONCLUSION The nematicidal metabolites from S. chamaejasme roots could be used as lead compounds for developing botanically based nematicides for the management of pine wilt disease.

Abstract
Five novel tigliane-type diterpenes, stelleracins A-E (3-7), a novel flavanone dimer, chamaeflavone A (8), and six known compounds were isolated from the roots of Stellera chamaejasme. Their structures were elucidated by extensive spectroscopic analyses. The isolated compounds were evaluated for anti-HIV activity in MT4 cells. New compounds 3-5 showed potent anti-HIV activity (EC90 0.00056-0.0068 μM) and relatively low or no cytotoxicity (IC50 4.4-17.2 μM). These new compounds represent promising new leads for development into anti-AIDS clinical trial candidates.

Abstract
Three natural products, 1,5-diphenylpentan-1-one, 1,5-diphenylpent-2-en-1-one, and 3-hydroxy-1,5-diphenylpentan-1-one, with good insecticidal activities were extracted from Stellera chamaejasme L. Based on their shared diaryl ketone moiety as 'pharmacophores', a series of diaryl ketones were synthesized and tested for insecticidal activity, acetylcholinesterase inhibitory activity, and antifungal activity. All synthesized compounds showed poor insecticidal and acetylcholinesterase inhibitory activities. Compound III with a furyl ring showed strong activities against plant pathogenic fungi. The IC(50) of compound (E)-1-(2,4-dichlorophenyl)-3-(furan-2-yl)- -prop-2-en-1-one (III(2) ) was 1.20 mg/L against Rhizoctonia solani, suggesting its strong potential as a novel antifungal drug.

Abstract
The acetone, chloroform, ethyl acetate, hexane and methanol extracts of peel and leaf extracts of Citrus sinensis, Ocimum canum, Ocimum sanctum and Rhinacanthus nasutus were tested against fourth instar larvae of malaria vector, Anopheles subpictus Grassi, Japanese encephalitis vector, Culex tritaeniorhynchus Giles (Diptera: Culicidae) and feeding deterrence to nymphs of cotton pest, Aphis gossypii Glover (Homoptera: Aphididae). The larval and nymph mortality were observed after 24 h of exposure. All extracts showed moderate larvicidal and nymphicidal effects; however, the highest mortality was found in peel chloroform extract of C. sinensis, leaf ethyl acetate extracts of O. canum and O. sanctum and leaf chloroform extract of R. nasutus against the larvae of A. subpictus (LC(50) = 58.25, 88.15, 21.67 and 40.46 ppm; LC(90) = 298.31, 528.70, 98.34 and 267.20 ppm), peel methanol extract of C. sinensis, leaf methanol extract of O. canum, ethyl acetate extracts of O. sanctum and R. nasutus against the larvae of C. tritaeniorhynchus (LC(50) = 38.15, 72.40, 109.12 and 39.32 ppm; LC(90) = 184.67, 268.93, 646.62 and 176.39 ppm), peel hexane extract of C. sinensis, leaf methanol extracts of O. canum and R. nasutus and leaf ethyl acetate extract of O. sanctum against the nymph of A. gossypii (LC(50) = 162.89, 80.99, 73.27 and 130.19 ppm; LC(90) = 595.40, 293.33, 338.74 and 450.90 ppm), respectively. These results suggest that the peel methanol extracts of C. sinensis and O. canum, ethyl acetate leaf extract of O. sanctum and leaf chloroform and ethyl acetate extract of R. nasutus have the potential to be used as an ideal eco-friendly approach for the control of the A. subpictus, C. tritaeniorhynchus and A. gossypii.

Abstract
Starting from the chemical structure of the botanical aphicides 1,5-diphenyl-1-pentanone and 1,5-diphenyl-2-penten-1-one, extracted from Stellera chamaejasme L., the authors designed and synthesized a series of novel compounds following the concept of bioisosterism. Their structures were established on the basis of (1)H NMR and GC-MS spectra, and the insecticidal activities of the compounds were evaluated against Aphis gossypii Glover. The results demonstrated that the substitution of a heterocycle for the phenyl ring was favourable. Thus, further modification of compound 2n, containing a furan ring, which showed excellent activity (LC(50) = 0.85 g L(-1)), is of some promise.
