Abstract
Cytochrome P450 enzymes (CYPs) play a crucial role in Phase I drug metabolism in the human body, and CYP activity toward compounds can significantly affect druggability, making early prediction of CYP activity and substrate identification essential for therapeutic development. Here, we established a deep learning model for assessing potential CYP substrates, DeepP450, by fine-tuning protein and molecule pretrained models through feature integration with cross-attention and self-attention layers. This model exhibited high prediction accuracy (0.92) on the test set, with area under the receiver operating characteristic curve (AUROC) values ranging from 0.89 to 0.98 in substrate/nonsubstrate predictions across the nine major human CYPs, surpassing current benchmarks for CYP activity prediction. Notably, DeepP450 uses only one model to predict substrates/nonsubstrates for any of the nine CYPs and exhibits certain generalizability on novel compounds and different categories of human CYPs, which could greatly facilitate early stage drug design by avoiding CYP-reactive compounds.

Abstract
Significance: Herbs are widely used worldwide. However, inappropriate use of some of the herbs can lead to herb-induced liver injury (HILI). Intriguingly, HILI incidents are on the rise, and our understanding of the underlying etiologies is in progress, and hence, an update on the current status of incidents as well as our understanding on the etiologies of HILI is appropriate. Recent Advances: HILI reports due to the use of some herbs that are traditionally considered to be safe are also on the rise. Furthermore, HILI due to the use of certain herbs in combination with other herbs (herb-herb interaction [HHI]) or non-herb components (herb-drug interaction [HDI]) has also been reported, suggesting a potentially important new type of inappropriate use of herbs. Critical Issues: Updated overviews focus on the epidemiology, etiology, phenotypes, and risk factors of HILI, as well as HDI and HHI, and analysis on several types of newly reported "toxic" effects of herbs based on types of hepatotoxicity and the HILI mechanisms. Future Directions: HILI will continue to be a significant public health challenge in the near future. In the light of the lack of broadly available guidelines and regulations for proper and safe uses of herbs worldwide, raising the public awareness of HILI will remain one of the most effective measures. In particular, it should include a better understanding of the contributing factors; a more detail subclassification and description of HILI, better characterization of the components/substances that could induce HILI; and development of HILI diagnosis based on the Roussel Uclaf Causality Assessment Method (RUCAM).

Biomimetic photosensitizer nanocrystals trigger enhanced ferroptosis for improving cancer treatment. J Control Release 2022; 352:1116-1133. [PMID: 36402233 DOI: 10.1016/j.jconrel.2022.11.026] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/05/2022] [Accepted: 11/14/2022] [Indexed: 11/22/2022]
Abstract
As a novel non-apoptotic cell death pathway, ferroptosis can effectively enhance the antitumor effects of photodynamic therapy (PDT) by disrupting intracellular redox homeostasis. However, the reported nanocomposites that combined the PDT and ferroptosis are cumbersome to prepare, and the unfavorable tumor microenvironment also severely interferes with their tumor suppressive effects. To address this inherent barrier, this study attempted to explore photosensitizers that could activate ferroptosis pathway and found that the photosensitizer aloe-emodin (AE) could induce cellular ferroptosis based on its specific inhibiting activity to Glutathione S-transferase P1(GSTP1), a key protein for ferroptosis. Herein, we prepared AE@RBC/Fe nanocrystals (NCs) with synergistic PDT and ferroptosis therapeutic effects by one-step emulsification to obtain AE NCs cores and further modification of red blood cells (RBC) membranes and ferritin. Benefiting from the involvement of ferritin, the prepared AE@RBC/Fe NCs provide not only sufficient oxygen for oxygen-dependent PDT, but also Fe3+ for iron-dependent ferroptosis in tumor cells. Furthermore, the biomimetic surface functionalization facilitated the prolonged circulation and cancer targeting of AE@RBC/Fe NCs in vivo. The in vitro and in vivo results demonstrate that AE@RBC/Fe NCs exhibit significantly enhanced therapeutic effects for the combined two antitumor mechanisms and provide a promising prospect for achieving PDT/ferroptosis synergistic therapy.

Diosbulbin B: An important component responsible for hepatotoxicity and protein covalent binding induced by Dioscorea bulbifera L. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 102:154174. [PMID: 35660353 DOI: 10.1016/j.phymed.2022.154174] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 01/13/2022] [Accepted: 05/13/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Dioscorea bulbifera L. (DBL) is an herbal medicine used for the treatment of thyroid diseases and tumors in China. However, the hepatotoxicity of DBL limits its wide safe use. Diosbulbin B (DSB) is the most abundant diterpene lactone occurring in DBL. Numbers of studies showed that this furanoterpenoid plays an important role in DBL-induced liver injury and that DSB is metabolized to a cis-enedial intermediate which reacts with protein to form protein covalent binding and induces hepatotoxicity. PURPOSE The present study aimed to define the association of DSB content in DBL with the severity of DBL hepatotoxicity to ensure the safe use of the herbal medicine in clinical practice and to determine the role of DSB in DBL-induced liver injury. METHODS Chemical chromatographic fingerprints of DBL were established by UPLC-MS/MS. Their hepatotoxicity potencies were evaluated in vitro and in vivo. Metabolic activation of DSB was evaluated by liver microsomal incubation. Protein modification was assessed by mass spectrometry and immunostaining. RESULTS The contents of DSB in DBL herbs collected from 11 locations in China varied dramatically with as much as 47-fold difference. The hepatotoxicity potencies of DBL herbs were found to be proportional to the contents of DSB. Intensified protein adduction derived from the reactive metabolite of DSB was observed in mice administered DBL with high contents of DSB. CONCLUSION The findings not only demonstrated that contents of DSB can be quite different depending on harvest location and special attention needs to pay for quality control of DBL but also suggest DSB is a key contributor for DBL-induced hepatotoxicity.

Abstract
Bletilla striata is consumed as food and herbal medicine. Militarine (MLT) is a major ingredient in B. striata. Previous studies demonstrated that MLT showed teratogenic toxicity to zebrafish embryos. The present study aimed to identify reactive metabolites possibly involved in the cytotoxicity of MLT and determine the metabolic pathways involved. MLT was found to be hydrolyzed to p-hydroxybenzyl alcohol (HBA) by β-glucosidase and esterases. The resulting HBA further underwent spontaneous dehydration to form quinone methide. HBA was also metabolized to the corresponding sulfate, followed by departure of the sulfate to generate a quinone methide. The resultant quinone methide reacted with hepatic glutathione (GSH) and protein to form the corresponding GSH conjugate and protein adduction. Additionally, inhibition of sulfotransferases (SULTs) attenuated the susceptibility of hepatocytes to the toxicity of MLT. This study provides that the hydrolytic enzymes β-glucosidase, esterases, and SULTs participate in the metabolic activation of MLT.

Abstract
Atherosclerosis is an inflammatory disease of high lethality associated with endothelial dysfunction. Due to the pathophysiological complexity and our incomplete understanding of the mechanisms for the development and progression of atherosclerosis, effective means for the prevention and treatment of atherosclerosis still need further exploration. This study was designed to investigate the potential effects and underlying mechanisms of aloe-emodin derivative (AED) on atherosclerosis. High fat diet (HFD) treated ApoE-/- mice were used as an animal model of atherosclerosis. Intragastric administration of aloe-emodin (AE) or AED for 12 weeks markedly reduced the atherosclerotic plaque in aorta with decreased plaque area, lipid accumulation, macrophage infiltration, collagen content and metabolic abnormalities. By comparison, AED produced more potent anti-atherosclerosis effects than AE at the same dose. AED enhanced production of autophagy flux in cultured human aortic endothelial cells (HAECs). Moreover, AED increased the expression of activating molecule in Beclin1-regulated autophagy 1 (AMBRA1), a key protein involved in autophagosome formation. Furthermore, knockdown of AMBRA1 blocked the promotion effect of AED on autophagy in HAECs. Taken together, AED facilitates endothelial autophagy via AMBRA1 during the progression of atherosclerosis, suggesting the potential application of this compound for atherosclerosis treatment.

Abstract
Doxorubicin (DOX) is a cytotoxic drug used for the treatment of breast cancer (BC). However, the rapid emergence of resistance toward doxorubicin threatens its clinical application, thus the need for combination therapy. Here, we interrogate the role of Emodin, a chemical compound with tumor inhibitory properties, in the resistance of BC to Doxorubicin. We first evaluated the efficacy of Emodin in the treatment of BC cells. We then used γH2A to examine doxorubicin-induced DNA damage in BC cells, with or without Emodin. Data from CCK-8, flow cytometry, and tumor xenograft assays showed that Emodin suppresses the growth of BC cells. Further, we demonstrated that Emodin enhances γH2A levels in BC cells. Moreover, bioinformatics analysis and western blot assays indicated that Emodin down-regulates the AKT1 expression, and marginally decreases the levels of DNA damage proteins (XRCC1, PARP1, and RAD51) as well as increased p53 expression in BC cells. Taken together, our data demonstrates that Emodin affects cell proliferation, and DNA damage pathways in BC cells, thus increasing the sensitivity of BC cells to doxorubicin. Besides, we confirmed that Emodin confers sensitization of BC to doxorubicin through AKT1-mediated DNA.

Aurantio-obtusin, an anthraquinone isolated from cassiae semen, possesses diverse pharmacological activities, including hypotensive, hypolipidemic and anti-inflammatory effects. However, our previous studies demonstrated that exposure to aurantio-obtusin induced hepatotoxicity, but the mechanisms of the toxic effects remain unknown. The purpose of the present study is to establish a strategy for the metabolite profiling of aurantio-obtusin in normal and liver-injured rats. This study aimed at identifying the in vivo metabolites and the metabolic profiling in rats after oral administration at a dose of aurantio-obtusin (4 and 200 mg/kg) by using an ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) and metabolynx™ software. A total of 39 metabolites were detected and 3 of them were compared with standard substances. The results indicated that the principal metabolism pathways of aurantio-obtusin in normal rats were glucuronidation and sulfation, while in rats with liver injury, demethylation, dehydroxylation and reduction were also observed and regarded as new metabolic patterns of aurantio-obtusin. These findings helped us to understand the pharmacological and toxicological mechanisms of aurantio-obtusin. Moreover, this study could help to elucidate the metabolic profiling of other anthraquinones.

Abstract
Aloe-emodin (AE) is a major anthraquinone ingredient of numerous traditional Chinese medicines with a variety of beneficial biological activities in vitro. Previous studies suggested that AE possessed cytotoxicity and genotoxicity. Nevertheless, the mechanisms of the toxic action of AE have not yet been fully clarified. The present study aimed at characterization of metabolic pathways of AE to better understand the mechanisms of AE-induced cytotoxicity. An AE-derived glutathione conjugate (AE-GSH) was observed in rat liver cytosol incubations containing AE and GSH, along with 3'-phosphoadenosine-5'-phosphosulfate (PAPS). Similar incubation fortified with N-acetylcysteine (NAC) in place of GSH offered an AE-NAC conjugate corresponding to the GSH conjugate. The formation of the two conjugates was found to require PAPS. The two conjugates were respectively detected in bile and urine of rats given AE. Sulfotransferase (SULT) inhibitor pentachlorophenol (PCP) suppressed the production of the observed AE-GSH/NAC conjugates in vivo, which suggested that SULTs participated in the process of the metabolic activation of AE. The presence of PCP attenuated cell susceptibility to AE-induced cytotoxicity. The present study illustrated potential association of sulfation-mediated bioactivation of AE with its cytotoxicity.
