    Abstract Mercury sulfide (HgS) exerts extensive biological effects on neuronal function. To investigate the direct target of HgS in neuronal cells, we developed a biotin-tagged HgS probe (bio-HgS) and employed an affinity purification technique to capture its target proteins. Then, we identified S-phase kinase-associated protein 1 (Skp1) as a potential target of HgS. Unexpectedly, we discovered that HgS covalently binds to Skp1 through a "Cys62-HgS-Cys120" mode. Moreover, our findings revealed that HgS inhibits the ubiquitin-protease system through Skp1 to up-regulate SNAP-25 expression, thereby triggering synaptic vesicle exocytosis to regulate locomotion ability in

    Abstract Neuroinflammation is initiated in response to a variety of endogenous and exogenous sources. As the resident macrophages of the central nervous system, the polarization of microglia into either the M1 pro-inflammatory phenotype or the M2 anti-inflammatory phenotype holds great promise as a therapeutic strategy for neuroinflammation. Natural products, comprising a vital chemical library with distinctive structures and diverse functions, have been extensively employed to modulate microglial polarization for the treatment of neuroinflammation. In this review, we present up-to-date and extensive insights into the therapeutic effects and underlying mechanisms of natural products in the context of neuroinflammation. Furthermore, the review aims to present a new perspective by focusing on the targets of natural compounds, elucidating the molecular mechanisms and guiding the transition from natural-derived lead compounds to potential anti-neuroinflammatory drugs. Additionally, we provide a comprehensive overview of the challenges and limitations associated with the utilization of natural products for neuroinflammation therapy.

    Abstract There is an urgent requirement to acquire a comprehensive comprehension of novel therapeutic targets for prostate cancer to facilitate the development of medications with innovative mechanisms. In this study, we identified gambogic acid (GBA) as a specific pyroptosis inducer in prostatic cancer cells. By using a thermal proteome profiling (TPP) strategy, we revealed that GBA induces pyroptosis by directly targeting the canopy FGF signaling regulator (CNPY3), which was previously considered "undruggable". Moreover, through the utilization of the APEX2-based proximity labeling method, we found that GBA recruited delactatease SIRT1, resulting in the elimination of lysine lactylation (Kla) on CNPY3. Of note, SIRT1-mediated delactylation influenced the cellular localization of CNPY3 to promote lysosome rupture for triggering pyroptosis. Taken together, our study identified CNPY3 as a distinctive cellular target for pyroptosis induction and its potential application in prostate cancer therapy.

    Abstract Fibroblast-like synoviocytes (FLS) play an important role in rheumatoid arthritis (RA)-related swelling and bone damage. Therefore, novel targets for RA therapy in FLS are urgently discovered for improving pathologic phenomenon, especially joint damage and dyskinesia. Here, we suggested that pyruvate kinase M2 (PKM2) in FLS represented a pharmacological target for RA treatment by antimalarial drug artemisinin (ART). We demonstrated that ART selectively inhibited human RA-FLS and rat collagen-induced arthritis (CIA)-FLS proliferation and migration without observed toxic effects. In particular, the identification of targets revealed that PKM2 played a crucial role as a primary regulator of the cell cycle, leading to the heightened proliferation of RA-FLS. ART exhibited a direct interaction with PKM2, resulting in an allosteric modulation that enhances the lactylation modification of PKM2. This interaction further promoted the binding of p300, ultimately preventing the nuclear translocation of PKM2 and inducing cell cycle arrest at the S phase. In vivo, ART obviously suppressed RA-mediated synovial hyperplasia, bone damage and inflammatory response to further improve motor behavior in CIA-rats. Taken together, these findings indicate that directing interventions towards PKM2 in FLS could offer a hopeful avenue for pharmaceutical treatments of RA through the regulation of cell cycle via PKM2 lactylation.

    Abstract Neuroinflammation is a leading cause for neurological disorders. Carbazole alkaloids, isolated from the medicinal plants of Murraya species (Rutaceae), have exhibited wide pharmacological activities particularly for neuroinflammation. However, its underlying cellular targets and molecular mechanisms still remain unclear. In current study, we found that murrayafoline A (MA), a carbazole alkaloid obtained from Murraya tetramera, potently inhibited the production of neuroinflammation mediators, such as nitric oxide (NO), TNF-α, IL-6 and IL-1β in LPS-induced BV-2 microglial cells. Then, we performed thermal proteome profiling (TPP) strategy to identify Specificity protein 1 (Sp1) as a potential cellular target of MA. Moreover, we performed surface plasmon resonance (SPR), cellular thermal shift assay (CETSA) and drug affinity responsive target stability (DRATS) assays to confirm the direct interaction between MA and Sp1. Furthermore, we downregulated Sp1 expression in BV2 cells using siRNA transfection, and observed that Sp1 knockdown significantly antagonized MA-mediated inhibition of neuroinflammation mediator production. Meanwhile, Sp1 knockdown also markedly reversed MA-mediated inactivation of IKKβ/NF-κB and p38/JNK MAPKs pathways. Finally, in vivo studies revealed that MA significantly suppressed the expression of Iba-1, TNF-α, and IL-6, while increased the number of Nissl bodies in the brains of LPS-induced mice. Taken together, our study demonstrated that MA exerted obvious anti-neuroinflammation effect by directly targeting Sp1, thereby inhibiting NF-κB and MAPK signaling pathways. Our findings also provided a promising direction of pharmacological targeting Sp1 for anti-neuroinflammation therapeutics as well as novel agent development.

    Abstract This study aimed to identify the direct pharmacological targets of Jingfang Granules in treating infectious pneumonia via "target fishing" strategy. Moreover, the molecular mechanism of Jingfang Granules in treating infectious pneumonia was also investigated based on target-related pharmacological signaling pathways. First, the Jingfang Granules extract-bound magnetic nanoparticles were prepared, which were incubated with lipopolysaccharide(LPS)-induced mouse pneumonia tissue lysates. The captured proteins were analyzed by high-resolution mass spectrometry(HRMS), and the target groups with specific binding to the Jingfang Granules extract were screened out. Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis was used to identify the target protein-associated signaling pathways. On this basis, the LPS-induced mouse model of infectious pneumonia was established. The possible biological functions of target proteins were verified by hematoxylin-eosin(HE) staining and immunohistochemical assay. A total of 186 Jingfang Granules-specific binding proteins were identified from lung tissues. KEGG pathway enrichment analysis showed that the target protein-associated signaling pathways mainly included Salmonella infection, vascular and pulmonary epithelial adherens junction, ribosomal viral replication, viral endocytosis, and fatty acid degradation. The target functions of Jingfang Granules were related to pulmonary inflammation and immunity, pulmonary energy metabolism, pulmonary microcirculation, and viral infection. Based on the in vivo inflammation model, Jingfang Granules significantly improved the alveolar structure of the LPS-induced mouse model of infectious pneumonia and down-regulated the expressions of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6). Meanwhile, Jingfang Gra-nules significantly up-regulated the expressions of key proteins of mitochondrial function COX Ⅳ and ATP, microcirculation-related proteins CD31 and Occludin, and proteins associated with viral infection DDX21 and DDX3. These results suggest that Jingfang Gra-nules can inhibit lung inflammation, improve lung energy metabolism and pulmonary microcirculation, resist virus infection, thus playing a protective role in the lung. This study systematically explains the molecular mechanism of Jingfang Granules in the treatment of respiratory inflammation from the perspective of target-signaling pathway-pharmacological efficacy, thereby providing key information for clinical rational use of Jingfang Granules and expanding potential pharmacological application.

    Abstract Traditional Chinese medicine(TCM) is a complex system with multiple chemical compositions. The most significant character of TCM is that the chemical compositions interact with each other by multi-target synergism to treat diseases. Previous reports mainly focused on the investigation of single signaling pathway detection or the phenotypic analysis of proteomics difference; however, no studies have been conducted on the identification of direct targets of TCM. Therefore, it is difficult to analyze the molecular mechanism of traditional Chinese medicine from the target source, and it is difficult to explain its traditional efficacy scientifically, thus seriously affecting its clinical application and internationalization. In this article, we discussed the methodology for the identification of direct TCM targets(groups), and presented the strategy for preparation of TCM chemical composition solid coupling beads, as well as of enrichment and identification strategy of target proteins based on photosensitive coupling technique. We also discussed the advantages and limitations of this strategy, and put forward some new ideas for the future developments. We hope this article can provide some guidance and reference significance for the researchers on TCM pharmacology study, especially on target identification.
