Bombyx batryticatusis the dried body of silkworm (Bombyx moriLinnaeus) larvae infected withBeauveria bassiana. It is widely used in traditional Chinese medicine for treating convulsions, epilepsy, and hyperglycemia. In this study,Bombyx batryticatusand its extract were prepared. The total reducing power, hydroxyl radical scavenging and superoxide anion radical scavenging activities, as well as the α-glucosidase inhibitory activity ofBombyx batryticatusextract were superior to those of normal silkworm larvae extract. Among them, the IC50value ofBombyx batryticatusextract for α-glucosidase was 5.76 mg/mL, while that of normal silkworm larvae extract was 7.0 mg/mL. Untargeted metabolomic analysis was employed to compare the material composition of normal silkworm larvae andBombyx batryticatus. The results revealed 101 metabolic differences between the two groups, including a significant increase in fatty acids and their derivatives in theBombyx batryticatusextract. Further separation and purification of theBombyx batryticatusextract were performed using solvents of varying polarity. The chloroform fraction exhibited the highest inhibitory activity against α-glucosidase, with an IC50value of 0.217 mg/mL. LC-MS further identified compounds in the chloroform fraction, suggesting that those alkaloids, fatty acids, and their derivatives may be responsible for its strong α-glucosidase inhibitory activity. This study elucidates the material basis underlying the pharmacological effects ofBombyx batryticatus, particularly its hypoglycemic components, thereby providing critical experimental support for its future development and application in medicine.

Bombyx batryticatus(BB) is an anticonvulsant animal medicine in traditional Chinese medicine (TCM) and acts on the central nervous system. This research aimed to study the anticonvulsant effects of different polarity fractions of extracts from BB and to explore the components conferring anticonvulsant activity. Materials and methods: Crude extracts of BB at 20 g/kg were divided into different polarity fractions (petroleum ether, chloroform, ethyl acetate, water) and were administered to groups of mice before injecting pentylenetetrazol (PTZ) to induce convulsions. The animals were placed in chambers, and their behaviors were recorded for 30 min following the injection. Latency time, percent of protection, convulsion, convulsion rate, and convulsion score were determined for these mice. The compounds present in the different fractions were analyzed, and those from the fraction that conferred anticonvulsant activity were identified by high-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF MS) and molecular networking (MN). The chloroform extract fractions (B-C) clearly increased the seizure latency time and protection percentage and decreased the convulsion percentage compared to the control group. The anticonvulsant effect of other extract fractions was not significant. Our study shows that the chloroform extract fractions (B-C) of BB have a significant anticonvulsant effect. We also identified 17 compounds including lumichrome, pheophorbide A, and episyringaresinol 4′-O-beta-d-glucopyranose that were found for the first time. The results of this study may lay the groundwork for studying compounds derived fromBombyx batryticatusand their anticonvulsant effect.Keywords:Bombyx batryticatus;anticonvulsant activity;different polar fractions;UHPLC-Q-TOF-MS/MS;molecular networking

Background:Chronic atrophic gastritis precancerous lesions (PL-CAG) are characterized by the atrophy of gastric mucosal glands, often accompanied by intestinal metaplasia or dysplasia. Timely intervention and treatment can effectively reverse its malignant progression and prevent the onset of gastric cancer. Bombyx Batryticatus (BB) exhibits a range of pharmacological effects, including anticoagulation, antiepileptic properties, anticancer activity, and antibacterial effects. However, the pharmacological basis and mechanisms underlying BB’s efficacy in treating PL-CAG remain unclear.Methods:A three-factor modeling approach was implemented to develop a rat PL-CAG model, while the MNNG-induced PLGC (precancerous lesions of gastric cancer) cell model was served as a cell PL-CAG model. UPLC-QE-Orbitrap-MS/MS (Ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry) was utilized to perform an in-depth analysis of the components in the plasma extract of BB. Leveraging network pharmacology, molecular docking analyses, and experimental validation, we initially elucidated the potential mechanisms through which BB mediates its therapeutic effects on PL-CAG at both in vivo and in vitro levels.Results:Prototype compounds of 42 blood-entering components were identified by UPLC-QE-Orbitrap-MS/MS analysis. Network pharmacology analysis and molecular docking studies indicate that the core targets are primarily enriched in the PI3K-Akt signaling pathway, and the key components, including Nepitrin, Quercetin 3-O-neohesperidoside, Rutin, and others, exhibited stable docking conformations with the first eleven pivotal targets. Both in vivo and in vitro experiments validated that BB may effectively treat PL-CAG via modulation of the PI3K-Akt signaling pathway.Conclusions:The therapeutic efficacy of BB in the management of PL-CAG may be achieved through the synergistic interaction of multiple components and targets, which may be more closely related to the inhibition of the PI3K/AKT signaling pathway. This approach will establish a solid experimental foundation and provide essential data for the clinical application of BB in treating PL-CAG, while also facilitating further research initiatives.

Treating acute lung injury (ALI) presents significant challenges due to adverse drug reactions. This study systematically explored the protective effects and mechanisms of a flavonoid-rich extract fromBombyx batryticatus(FBB), a traditional Chinese medicine, in combating ALI. Through UPLC-MS/MS analysis, we identified 163 flavonoid components in FBB for the first time, including flavonoids, flavonols, and chalcones. Unlike single-component flavonoid therapies, FBB provides synergistic regulation across multiple targets and pathways. Network pharmacology predictions, supported by experimental validation, revealed that FBB primarily suppresses the expression of inflammatory factors (IL-1β, IL-6, TNF-α) and oxidative stress markers (iNOS, COX-2) by modulating the PI3K/Akt, MAPK, and NF-κB signaling pathways. FBB inhibits pro-inflammatory responses and upregulates chemokine receptors like Ccr1 and Ccr2, along with IL-2Rb, at the transcriptional level. This suggests its potential to promote inflammation resolution and tissue repair through immune microenvironment remodeling, rather than mere immunosuppression. Additionally, FBB demonstrated significant anti-apoptotic effects both in vitro and in vivo, effectively reducing pulmonary edema and vascular permeability. Its complex composition and multi-pathway synergistic mechanisms offer broader regulatory potential and unique therapeutic advantages in treating ALI compared to single flavonoid compounds or conventional hormone drugs like dexamethasone (DEX). This study reveals a novel mechanism by which FBB, a multi-component natural drug, exerts therapeutic effects in ALI, providing a theoretical and experimental foundation for developing flavonoid-based compound preparations from traditional Chinese medicine.

The traditional Chinese drug Bombyx Batryticatus (BB), which is also named the white stiff silkworm, has been widely used in Chinese clinics for thousands of years. It is famous for its antispasmodic and blood circulation-promoting effects. Cardiomyocyte hypertrophy, interstitial cell hyperplasia, and myocardial fibrosis are closely related to theN-glycosylation of key proteins. To examine the alterations ofN-glycosylation that occur in diabetic myocardium during the early stage of the disease, and to clarify the therapeutic effect of 1-Deoxynojirimycin (1-DNJ) extracted from BB, we used the db/db (diabetic) mouse model and an approach based on hydrophilic chromatography solid-phase extraction integrated with an liquid Chromatograph Mass Spectrometer (LC-MS) identification strategy to perform a site-specificN-glycosylation analysis of left ventricular cardiomyocyte proteins. Advanced glycation end products (AGEs), hydroxyproline, connective tissue growth factor (CTGF), and other serum biochemical indicators were measured with enzyme-linked immunosorbent assays (ELISA). In addition, the α-1,6-fucosylation ofN-glycans was profiled with lens culinaris agglutinin (LCA) lectin blots and fluorescein isothiocyanate (FITC)-labelled lectin affinity histochemistry. The results indicated that 1-DNJ administration obviously downregulated myocardium proteinN-glycosylation in db/db mice. The expression levels of serum indicators and fibrosis-related cytokines were reduced significantly by 1-DNJ in a dose-dependent manner. The glycan α-1,6-fucosylation level of the db/db mouse myocardium was elevated, and the intervention effect of 1-DNJ administration onN-glycan α-1,6-fucosylation was significant. To verify this result, the well-known transforming growth factor-β (TGF-β)/Smad2/3 pathway was selected, and core α-1,6-fucosylated TGF-β receptor II (TGFR-βII) was analysed semi-quantitatively with western blotting. The result supported the conclusions obtained from LCA lectin affinity histochemistry and lectin blot analysis. The expression level of α-1,6-fucosyltransferase (FUT8) mRNA was also detected, and the results showed that 1-DNJ administration did not cause obvious inhibitory effects on FUT8 expression. Therefore, the mechanism of 1-DNJ for relieving diabetic cardiomyopathy (DCM)-associated fibrosis can be concluded as the inhibition ofN-acetylglucosamine (N-GlcNAc) formation and the reduction of substrate concentration.Keywords:1-DNJ;diabetic cardiomyopathy;fibrosis;N-glycosylation;α-1,6-fucosylation

This study investigates the consistency between the formula granule decoction of stir-fried Bombyx Batryticatus(JC-DGD) and its traditional decoction (JC-TD) counterpart, using roasted Bombyx Batryticatus as a representative example.First, used high-performance liquid chromatography (HPLC) to establish the fingerprints of JC-TD and JC-DGD from four manufacturers (A, B, C, and D) and assess their similarity. There was no significant difference between the two ( P > 0.05).Quantified five key index components, including uracil.Compared the protein and crude polysaccharide contents using the Coomassie Brilliant Blue and phenol-sulfuric acid methods. The mean total content of index components, proteins, and crude polysaccharides in 10 batches of JC-TD was set as 1. The contents of index components in different categories - JC-DGD-provincial standard(JC-DGD-PS), JC-DGD-enterprise standard(JC-DGD-ES), TD, DGD, and DGCM from manufacturers A, B, C, and D—were 1.23, 0.38, 1.00, 0.72, 1.28, 0.58, 0.45, and 0.27, respectively. The protein contents were 1.51, 0.46, 1.00, 0.88, 1.43, 0.93, 0.35, and 0.66, respectively. The crude polysaccharide contents was 9.01, 0.74, 1.00, 4.05, 10.57, 1.96, 0.38, and 1.77, respectively. We identified 32 differential volatile organic compounds, including fenugreek lactone, using GC-IMS. Then evaluated the anticonvulsant effects of JC-TD and JC-DGD using an acute convulsion mouse model induced by pentylenetetrazole. The results showed that JC-DGD-A > JC-TD ≈ JC-DGD-B ( P > 0.05)) were superior to those of JC-DGD-C and JC-DGD-D ( P < 0.01). Finally, calculate the recommended equivalent ratio of Chinese medicine formula granules (DGCM). The manufacturers A, B, C, and D were adjusted from 1:3, 1:10, 1:10, and 1:11–1:4.54 ± 0.51, 1:5.24 ± 2.22 (JC-B3 without adjustment: 1:3.6), 1:5.17 ± 0.49, and 1:3.44 ± 0.59, respectively. The overall, and the consistency between the two was analyzed through correlation analysis, cluster analysis, and multi-index dimensionality reduction discriminant analysis.Comprehensive results indicated that the quality of JC-DGD-A was significantly higher than that of JC-TD, while JC-DGD-B exhibited similar quality to JC-TD. In contrast, the quality of JC-DGD-C and JC-DGD-D was significantly lower than that of JC-TD. To enhance product quality and ensure the scientific rationality of clinical applications, manufacturers must adhere to national and provincial standards for formula granule drugs.
