Abstract
BACKGROUND The scarcity of drugs targeting AML cells poses a significant challenge in AML management. Z-Ligustilide (Z-LIG), a phthalide compound, shows promising pharmacological potential as a candidate for AML therapy. However, its precise selective mechanism remains unclear. PURPOSE In order to assess the selective inducement effects of Z-LIG on ferroptosis in AML cells and explore the possible involvement of the Nrf2/HO-1 pathway in the regulation of ferroptosis. METHODS Through in vitro cell proliferation and in vivo tumor growth tests, the evaluation of Z-LIG's anticancer activity was conducted. Ferroptosis was determined by the measurement of ROS and lipid peroxide levels using flow cytometry, as well as the observation of mitochondrial morphology. To analyze the iron-related factors, western blot analysis was employed. The up-regulation of the Nrf2/HO-1 axis was confirmed through various experimental techniques, including CRISPR/Cas9 gene knockout, fluorescent probe staining, and flow cytometry. The efficacy of Z-LIG in inducing ferroptosis was further validated in a xenograft nude mouse model. RESULTS Our study revealed that Z-LIG specifically triggered lipid peroxidation-driven cell death in AML cells. Z-LIG downregulated the total protein and nuclear entrance levels of IRP2, resulting in upregulation of FTH1 and downregulation of TFR1. Z-LIG significantly increased the susceptibility to ferroptosis by upregulating ACSL4 levels and simultaneously suppressing the activity of GPX4. Notably, the Nrf2/HO-1 pathway displayed a twofold impact in the ferroptosis induced by Z-LIG. Mild activation suppressed ferroptosis, while excessive activation promoted it, mainly driven by ROS-induced labile iron pool (LIP) accumulation in AML cells, which was not observed in normal human cells. Additionally, Nrf2 knockout and HO-1 knockdown reversed iron imbalance and mitochondrial damage induced by Z-LIG in HL-60 cells. Z-LIG effectively inhibited the growth of AML xenografts in mice, and Nrf2 knockout partially weakened its antitumor effect by inhibiting ferroptosis. CONCLUSION Our study presents biological proof indicating that the selective initiation of ferroptosis in leukemia cells is credited to the excessive activation of the Nrf2/HO-1 pathway triggered by Z-LIG.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In many famous formulas of traditional Chinese medicine (TCM), the rhizome of Ligusticum chuanxiong (L. chuanxiong) is commonly used as an ingredient for promoting blood circulation and resolving blood stasis to treat diabetic nephropathy. However, its material basis and mechanism of action are still needed to be explored. AIM OF THE STUDY The aim of this work is to elucidate the potential effective parts (phthalides) of L. chuanxiong responsible for renal protection and to explore the possible mechanism of renal protection. MATERIALS AND METHODS A method based on column chromatography of macroporous resin was established to enrich an effective part (LCE70), and the composition of LCE70 was identified by HPLC-UV and UPLC-MS/MS methods. Mice model was induced by streptozotocin (STZ) to evaluate the protective effect of LCE70 on diabetic nephropathy (DN). In vitro, the suppressive effect of LCE70 on oxidative damage, inflammation and its mechanism were tested using immunoblot analysis, ELISA, etc. Cellular thermal shift assay (CETSA) was adopted to verify the interaction between the phthalides and the key targets involved in renal injury. RESULTS LCE70 displayed therapeutic potential against metabolic disorders, renal dysfunction, and fibrosis in a DN model induced by STZ in mice. Furthermore, it markedly reduced oxidative stress of the kidney in DN mice by activating Nrf2 pathway. Z-ligustilide, the main component of LCE70, reacted with Keap1, and thus promoted Nrf2 dissociating from Keap1 to activate Nrf2 pathway. CONCLUSIONS LCE70 improved hyperglycemia-induced renal function by enhancing the Nrf2 activation, reducing collagen deposition, and alleviating inflammation and oxidative stress, which suggested its potential as a therapeutic agent for DN.

Abstract
BACKGROUND Nuclear receptors NUR77 and NOR1 were identified as critical targets in acute myeloid leukemia (AML) therapy. Previously, we showed that Z-ligustilide (Z-LIG) selectively targeted AML by restoring NUR77 and NOR1. However, its downstream mechanisms are yet to be elucidated. METHODS SRB staining assay was used to measure cell viability. Cell apoptosis, mitochondrial membrane potential and mitochondrial reactive oxygen species were analyzed using flow cytometry. The potential targets of Z-LIG in AML HL-60 cells were evaluated by RNA sequencing. Changes in RNA levels were measured using quantitative RT-qPCR and western blot analysis was used to detect the expression of proteins. RESULTS Z-LIG preferentially induced mitochondrial dysfunction in HL-60 cells compared with 293T cells. Furthermore, RNA sequencing revealed that mitochondrial transcription and translation might be potential Z-LIG targets inhibiting HL-60 cells. NUR77/NOR1 overexpression significantly reduced the mitochondrial ATP and mitochondrial membrane potential and increased mitochondrial reactive oxygen species in HL-60 cells but not in 293T cells. Moreover, Z-LIG induced mitochondrial dysfunction by restoring NUR77 and NOR1 in HL-60 cells. Compared with HL-60 cells, the apoptosis-inducing activities of NUR77/NOR1 and Z-LIG were significantly reduced in HL-60 ρ0 cells depleted in mitochondrial DNA (mt-DNA). Moreover, NUR77/NOR1 and Z-LIG downregulated mitochondrial transcription and translation related proteins in HL-60 cells. Notably, Z-LIG remarkably reduced mitochondrial ATP in primary AML cells and showed anti-AML activity in mouse models of human AML. CONCLUSIONS Collectively, our findings suggested that Z-LIG selectively induces mitochondrial dysfunction in AML HL-60 cells by restoring NUR77 and NOR1, a process associated with interference in mtDNA transcription.

Abstract
Diabetes mellitus ranks as a major risk cause for disability and death around the world due to its complications, especially diabetic cardiomyopathy (DCM). Glucolipotoxicity is one of the critical causal factors of DCM. Recent finding confirms the beneficial roles of Z-ligustilide in diabetes mellitus. Nevertheless, its efficacy in DCM remains elusive. Here, Z-ligustilide elevated high glucose/high palmitic acid (HG/P)-inhibited cell viability and attenuated HG/P-induced cell apoptosis, caspase-3 activity, pro-apoptotic Bax and anti-apoptotic Bcl-2 protein expression. Furthermore, Z-ligustilide alleviated HG/P-evoked oxidative damage by decreasing HG/P-induced elevation in ROS, lactate dehydrogenase (LDH) and malondialdehyde (MDA) leakage, but increasing antioxidant enzyme-superoxide dismutase (SOD) and glutathione (GSH) levels suppressed by HG/P. Concomitantly, Z-ligustilide attenuated HG/P-induced cardiomyocyte fibrosis by increasing MMP-14 expression and diminishing HG/P-enhanced fibrotic protein expression, including collagen I, collagen II and TGF-β. Mechanistically, Z-ligustilide offset the adverse effects of HG/P on the activation of the AMPK/GSK-3β/Nrf2 pathway. Importantly, blocking the AMPK signaling overturned the protective efficacy of Z-ligustilide against HG/P-induced cardiomyocyte oxidative damage, inflammation and fibrosis. Together, these findings highlight that Z-ligustilide may alleviate glucolipotoxicity-induced cardiomyocyte dysfunction by regulating cell oxidative injury, inflammation and fibrosis via the AMPK/GSK-3β/Nrf2 pathway. Consequently, Z-ligustilide may represent a promising therapeutic agent against DCM by restoring cardiomyocyte dysfunction.

Abstract
Depression is a significant public health issue and its neuropathogenesis is associated with the dysfunction of progesterone and allopregnanolone biosynthesis. Z-ligustilide (LIG), one of the main components of the herb Angelica sinensis (Oliv.) Diels (AS), is reported to have antidepressant activities. The present study aimed to evaluate the antidepressant-like effects of LIG via behavioral tests and to measure the levels of progesterone and allopregnanolone in the prefrontal cortex and hippocampus. The results demonstrated that LIG (20 and 40 mg/kg) exerted antidepressant-like effects, confirmed by increased mobility, locomotion, rearing frequency and preference to sucrose. Furthermore, the levels of progesterone and allopregnanolone in the prefrontal cortex and hippocampus were markedly increased following treatment with LIG (20 and 40 mg/kg), indicating that both neurosteroids could serve a significant role in the antidepressant-like effects of LIG.

The plasma concentrations of senkyunolide A, N-butylphthalide, new osthol lactone, Z-ligustilide and butenyl phthalide were determined with UPLC-MS/MS. The content determination was conducted at the chromatographic conditions as follows: Shim-pack GIST C_(18)-AQ HP column(2.1 mm×100 mm, 3 μm), mobile phase of 0.1% formic acid solution(A)-acetonitrile(B), gradient elution, flow rate of 0.3 mL·min~(-1), column temperature of 35 ℃ and injection volume of 2 μL. The mass spectra were obtained with electrospray ion source(ESI), positive ion mode and multi reaction monitoring. CPTA/β-CD inclusion compound was prepared by grinding method, DAS 2.0 software was used to model the data, and the absolute bioavailability of CPTA and relative bioavailability of inclusion compound were calculated. Finally, the methods for the determination of five components of senkyunolide A, N-butylphthalide, new osthol lactone, Z-ligustilide and butenyl phthalide in CPTA, were successfully established. The linear relationship among the five components was good within their respective ranges, r>0.99. The absolute bioavailability of the five components in rats was 22.30%, 16.32%, 21.90%, 10.16% and 12.43%, respectively. After CPTA/β-CD inclusion was prepared, the relative bioavailability of the five components was 138.69%, 198.39%, 218.01%, 224.54% and 363.55%, respectively, significantly improved. This method is rapid, accurate and sensitive, so it is suitable for the pharmacokinetic study of extracts in traditional Chinese medicine and their preparations.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is a devastating hematologic malignancy with a high mortality. The nuclear receptors Nur77 and NOR-1 are commonly downregulated in human AML blasts and have emerged as key therapeutic targets for AML. METHODS This study aimed to identify Z-ligustilide (Z-LIG), the main phthalide of Rhizoma Chuanxiong, as a potential agent that can selectively target AML. The anti-AML activity of Z-LIG was evaluated in vitro and in vivo, and the effect and underlying mechanisms of Z-LIG on the restoration of Nur77 and NOR-1 was determined. Moreover, the role of Nur77 and NOR-1 in the regulation of Z-LIG-induced apoptosis and differentiation of AML cells was explored. RESULTS Z-LIG preferentially inhibited the viability of human AML cells, as well as suppressed the proliferation and colony formation ability. Notably, a concentration-dependent dual effect of Z-LIG was observed in AML cells: inducing apoptosis at relatively high concentrations (25 μM to 100 μM) and promoting differentiation at relatively low concentrations (10 μM and 25 μM). Importantly, Z-LIG restored Nur77 and NOR-1 expression in AML cells by increasing Ace-H3 (lys9/14) enrichment in their promoters. Meanwhile, Z-LIG enhanced the recruitment of p300 and reduced the recruitment of HDAC1, HDAC4/5/7, and MTA1 in the Nur77 promoter and enhanced the recruitment of p-CREB and reduced HDAC1 and HDAC3 in the NOR-1 promoter. Furthermore, Z-LIG-induced apoptosis was shown to be correlated with the mitochondria localization of Nur77/NOR-1 and subsequent Bcl-2 conformational change, converting Bcl-2 from a cyto-protective phenotype into a cyto-destructive phenotype. Z-LIG-promoted differentiation was found to be related to Nur77/NOR-1-mediated myeloid differentiation-associated transcription factors Jun B, c-Jun, and C/EBPβ. Finally, silencing of Nur77 and NOR-1 attenuated anti-AML activity of Z-LIG in NOD/SCID mice. CONCLUSIONS Our study suggests that Z-LIG may serve as a novel bifunctional agent for AML by restoring Nur77/NOR-1-mediated apoptosis and differentiation.

Abstract
According to World Health Organisation (WHO) air pollution increases the risk of cardiovascular disorders, respiratory diseases, including COPD, lung cancer and acute respiratory infections, neuro-degenerative and other diseases. It is also known that various phytochemicals may mitigate such risks. This study tested if phytochemicals mangiferin (MNG) and Z-ligustilide (Z-LG) may protect PAH-exposed human lung bronchial epithelial cells (BEAS-2B). Organic PAH extract was obtained from the urban fine PM with high benzo(a)pyrene content collected in Eastern European mid-sized city during winter heating season. Cell proliferation traits and levels of intracellular oxidative stress were examined. Effect of MNG (0.5 µg/mL) alone or in combination with PAH on bronchial epithelium wound healing was evaluated. Both phytochemicals were also evaluated for their antioxidant properties in acellular system. Treatment with MNG produced strong cytoprotective effect on PAH-exposed cells (p < 0.01) while Z-LG (0.5 µg/mL) exhibited strong negative effect on cell proliferation in untreated and PAH-exposed cells (p < 0.001). MNG, being many times stronger antioxidant than Z-LG in chemical in vitro assays (p < 0.0001), was also able to decrease PAH-induced oxidative stress in the cell cultures (p < 0.05). Consequently MNG ameliorates oxidative stress, speeds up wound healing process and restores proliferation rate in PAH-exposed bronchial epithelium. Such protective effects of MNG in air pollution affected airway epithelium stimulate further research on this promising phytochemical.

Abstract
The key in vivo metabolites of a drug play an important role in its efficacy and toxicity. However, due to the low content and instability of these metabolites, they are hard to obtain through in vivo methods. Electrochemical reactions can be an efficient alternative to biotransformation in vivo for the preparation of metabolites. Accordingly, in this study, the metabolism of Z-ligustilide was investigated in vitro by electrochemistry coupled online to mass spectrometry. This work showed that five oxidation products of the electrochemical reaction were detected and that two of the oxidation products (senkyunolide I and senkyunolide H) were identified from liver microsomal incubation as well. Furthermore, after intragastric administration of Z-ligustilide in rats, senkyunolide I and senkyunolide H were detected in the rat plasma and liver, while 6,7-epoxyligustilide, a key intermediate metabolite of Z-ligustilide, was difficult to detect in vivo. By contrast, 6,7-epoxyligustilide was obtained from the electrochemical reaction. In addition, for the first time, 6 mg of 6,7-epoxyligustilide was prepared from 120 mg of Z-ligustilide. Therefore, electrochemical reactions represent an efficient laboratory method for preparing key drug metabolites.

Abstract
Emerging evidence indicates epigenetic modification represses estrogen receptor α (ERα) and contributes to the resistance to tamoxifen in aggressive ERα-negative (ERα−) breast cancer. Z-ligustilide is a major compound in Radix Angelica sinensis, an herb from traditional Chinese medicine (TCM) most frequently prescribed for breast cancer. However, the role of Z-ligustilide in ERα− breast cancer and epigenetic modification remains largely unknown. Herein we showed, for the first time, that Z-ligustilide restored the growth inhibition of tamoxifen on ERα− breast cancer cells. Apoptosis and S and G2/M phases cell cycle arrest were induced by combinatorial Z-ligustilide and tamoxifen. Importantly, Z-ligustilide reactivated the ERα expression and transcriptional activity, which is proved to be indispensable for restoring the sensitivity to tamoxifen. Interestingly, Z-ligustilide increased Ace-H3 (lys9/14) enrichment in the ERα promoter. Moreover, Z-ligustilide dramatically reduced the enrichment of metastasis-associated protein 1 (MTA1) as well as IFN-γ-inducible protein 16 (IFI16) and histone deacetylases (HDACs) onto the ERα promoter. Meanwhile, Z-ligustilide downregulated MTA1, IFI16 and HDACs, which caused destabilization of the corepressor complex. Collectively, our study not only highlights Z-ligustilide as a novel epigenetic modulator, but also opens new possibilities from TCM for treating aggressive tamoxifen-resistant breast cancer.

Abstract
Autophagy plays a pro-survival role in the tamoxifen-resistant breast cancer cells. Herein we found that autophagy was concomitantly induced in tamoxifen-resistant MCF-7 (MCF-7TR5) cells through the dissociation of Bcl-2 from Beclin 1 and subsequent enhancement of interaction among the ATG14-Beclin1-PI3KC3 complex. Moreover, higher level of DNA damage was observed in MCF-7TR5 cells with the decreased BRCA1 and RAD51 level and the increased Ku80 level. Interestingly, Nur77 was selectively degraded by autophagy, which causes the release of Ku80 from the Nur77-Ku80 complex, resulting in the increase of the DNA binding of Ku80 and DNA-PKcs. Meanwhile, Z-ligustilide, a phthalide compound from Radix Angelica sinensis, was shown to inhibit the autophagic flux by blocking the autophagosome-lysosome fusion. Importantly, Z-ligustilide-mediated autophagy inhibition restored Nur77 expression in MCF-7TR5 cells. Furthermore, Z-ligustilide promoted the interaction of Nur77 with Ku80 and thereby abolished the association of DNA-PKcs with DNA ends. Moreover, Z-ligustilide sensitized MCF-7TR5 cells in a caspase-independent cell death and enhanced the DNA damage caused by tamoxifen, which was found to be attenuated by shNur77. Together, these findings not only provide important insights into the formation of tamoxifen resistance in breast cancer cells, but also suggest Z-ligustilide may function as a novel autophagy inhibitor to overcome chemoresistance.

Abstract
Z-Ligustilide (Z-LIG) is a major component in Rhizoma Chuanxiong, which has been traditionally used as a health food supplement for the prevention of cerebrovascular disease in China. This study investigates the ability of intranasal Z-LIG pretreatment to enhance protection against neuronal damage in rats with middle cerebral artery occlusion (MCAO) and the role of cellular stress response mechanisms Nrf2 and HSP70. Z-LIG significantly mitigated infarct volume, neurological dysfunction, blood-brain barrier disruption, and brain edema (p < 0.01). Moreover, Z-LIG prevented the loss of collagen IV, occludin, and ZO-1 (p < 0.05) and decreased MMP-2 and -9 levels (p < 0.01). Meanwhile, Z-LIG up-regulated NQO1 and HSP70. Notably, blockage of Nrf2-driven transcription or down-regulation of HSP70 remarkably attenuated the preventive effect of Z-LIG (p < 0.05). Together, intranasal delivery of Z-LIG enhanced protection against ischemic injury via Nrf2 and HSP70 signaling pathways and has prophylactic potential in the population at high risk of stroke.

Abstract
Alzheimer's disease (AD) is primarily characterized by the progressive loss of functional neurons in the brain. Therefore, compounds with neuroprotective property may have therapeutic value in treating AD. Z-ligustilide (Z-LIG) is an essential oil originally isolated from umbelliferous plants. In the current study, the neuroprotective effects and underlying mechanisms of Z-LIG against fibrillar aggregates of Aβ25-35 and Aβ1-42-induced neurotoxicity were investigated in both SH-SY5Y cells and differentiated PC12 cells. Z-LIG at 1-30 μM provided an effective neuroprotection, as evidenced by the increase in cell viability, as well as the decrease in LDH release and intracellular accumulation of reactive oxygen species. Additionally, Z-LIG markedly blocked Aβ fibrils-induced condensed nuclei and sub-G1 accumulation suggestive of apoptosis. Furthermore, Z-LIG substantially reversed the activation of phosphorylated p38 and the inhibition of phosphorylated Akt caused by Aβ25-35. LY294002, the specific inhibitor of PI3-K, significantly abrogated the protein expression of up-regulated phosphorylated Akt offered by Z-LIG. Most importantly, siRNA-mediated knockdown of PI3-K and p38 significantly abolished the neuroprotective effects of Z-LIG. The results taken together indicate that Z-LIG protects against Aβ fibrils-induced neurotoxicity possibly through the inhibition of p38 and activation of PI3-K/Akt signaling pathways concurrently. Z-LIG might be a potential candidate for further preclinical study aimed at the prevention and treatment of AD.

Abstract
PRIMARY OBJECTIVE Essential oil (EO) of Kelussia odoratissima Mozaff, whose main composition is Z-ligustilide, has been shown to have strong antioxidant and anti-inflammatory effects and potent neuroprotective properties. RESEARCH DESIGN This study examined whether or not the EO could ameliorate brain damage and behavioural dysfunction in a thromboembolic model of stroke in rats and compare its effects to that of the purified Z-ligustilide. METHODS AND PROCEDURES Stroke was induced in rats by middle cerebral artery occlusion using an autologous pre-formed clot. EO (10 mg kg(-1) and 45 mg kg(-1)) and Z-ligustilide (20 mg kg(-1)) were injected intraperitoneally 1 h prior to embolization. Behavioural scores, infarct size and brain oedema, as well as the level of tumour necrosis factor-alpha (TNF-α), malondialdehyde, glutathione, catalase and superoxide dismutase activity were determined in the ipsilateral cortex 24 hours following stroke induction. MAIN OUTCOMES AND RESULTS EO (45 mg kg(-1)), statistically similar to Z-ligustilide (20 mg kg(-1)), curtailed brain infarction and oedema, improved behavioural scores and prevented enhanced oxidative stress and TNF-α level in the ischaemic brain tissues. CONCLUSIONS The findings provide the first evidence of effectiveness of the extract in a thromboembolic model of stroke, whose action can be mediated, at least in part, by the antioxidative and anti-inflammatory mechanisms.

Abstract
Z-ligustilide (LIG), an essential oil extract from Radix Angelica sinensis, has broad pharmaceutical applications in treating cardiovascular and cerebrovascular diseases. Interaction of LIG with the major transport protein of human blood circulation, human serum albumin (HSA) has been investigated by steady-state, UV-vis and circular dichroism (CD) spectroscopic methods, as well as the effect of metal ions (e.g. Zn(2+), Cu(2+), Fe(3+), Co(2+), Ni(2+)) on the LIG-HSA system. Fluorescence results revealed that a moderate binding affinity (1.59 × 10(4) M(-1) at 298 K) between LIG and HSA with a 1:1 stoichiometry. Thermodynamic analysis of the binding data (ΔS = +12.96 J mol(-1) K(-1) and ΔH =- 20.11 kJ mol(-1)) suggested the involvement of hydrophobic and van der Waals forces, as well as hydrogen bonding in the complex formation. The specific binding distance r (3.75 nm) between donor (Trp-214) and acceptor (LIG) was obtained according to fluorescence resonance energy transfer. CD results showed that slight conformational changes occurred in the protein upon complexation with LIG.

Abstract
The presence of dimeric phthalides and other constituents in extracts of the vegetal species Ligusticum porteri was established by NMR spectroscopy. In comparative qualitative (1)H NMR analyses of acetone extracts of rhizomes from fresh and dried L. porteri samples, we found that the dimeric phthalides tokinolide B (3), diligustilide (4) and riligustilide (5) were naturally produced by the plant and not post-harvest products. We also obtained DOSY (1)H NMR data that provided both virtual separation and structural information for the phthalides present in a dry acetone extract of L. porteri. In addition, we developed a protocol for the quantification of dimeric phthalides, which is performed by calculating the relative ratio of the peak area of selected proton signals for some compounds with respect to the known signal of the internal standard, 4-dimethylaminopyridine. The protocol allows the rapid and direct quantification of dimeric phthalides and others constituents in fresh L. porteri rhizomes.
