Acetylcholinesterase (AChE) enzymes play an essential role in the development of Alzheimer’s disease (AD). Its excessive activity causes several neuronal problems, particularly psychopathies and neuronal cell death. A bioactive pose on the hAChE B site of the human acetylcholinesterase (hAChE) enzyme employed in this investigation, which was obtained from the Protein Data Bank (PDB ID 4EY6), allowed for the prediction of the binding affinity and free binding energy between the protein and the ligand. Virtual screening was performed to obtain structures similar to Galantamine (GNT) with potential hAChE activity. The top 200 hit compounds were prioritized through the use of filters in ZincPharmer, with special features related to the pharmacophore. Critical analyses were carried out, such as hierarchical clustering analysis (HCA), ADME/Tox predictions, molecular docking, molecular simulation studies, synthetic accessibility (SA), lipophilicity, water solubility, and hot spots to confirm the stable binding of the two promising molecules (ZINC16951574-LMQC2, and ZINC08342556-LMQC5). The metabolism prediction, with metabolites M3-2, which is formed by Glutathionation reaction (Phase II), M1-2, and M2-2 formed from the reaction of S-oxidation and Aliphatic hydroxylation (Phase I), were both reactive but with no side effects. Theoretical synthetic routes and prediction of synthetic accessibility for the most promising compounds are also proposed. In conclusion, this study shows that in silico modeling can be used to create new drug candidate inhibitors for hAChE. The compounds ZINC16951574-LMQC2, and ZINC08342556-LMQC5 are particularly promising for oral administration because they have a favorable drug-likeness profile, excellent lipid solubility, high bioavailability, and adequate pharmacokinetics.

Background Dental pathogens, encompassing bacteria, viruses, and fungi, are pivotal in the development of oral health issues such as tooth decay, gum disease, and oral infections. Interestingly, recent research suggests a potential interconnection between dental pathogens and oral cancer, with evidence implicating certain oral pathogens in the initiation and progression of oral malignancies. Given the rising concern of antibiotic resistance and the limitations of conventional treatments, there is a compelling need for innovative therapeutic approaches. Methods The research involved the synthesis and analysis of zinc oxide nanoparticles (ZnO NPs) facilitated by piperine (PIP). Various techniques including UV spectroscopy, SEM, XRD, FTIR, and EDAX were employed to confirm their chemical composition and structural characteristics. Evaluations were conducted on the antioxidant and antimicrobial effectiveness of ZnO-PIP NPs through DPPH, ABTS, and MIC assays. Furthermore, cell viability and regulation of apoptotic gene expression on KB oral squamous carcinoma cells after the treatment were assessed to identify the potential anticancer properties of the ZnO-PIP NPs Results ZnO-PIP NPs showed significant antioxidant activity in both DPPH and ABTS assays, indicating their potential as potent scavengers of free radicals. The identified MIC of 50 μg/mL against dental pathogens highlighted the strong antimicrobial properties of ZnO-PIP NPs. Moreover, interaction analysis revealed the high binding affinity and complex amino acid interactions between ZnO-PIP NPs and receptors on dental pathogens. Additionally, in terms of anticancer activity, ZnO-PIP NPs exhibited a dose-dependent response against Human Oral Epidermal Carcinoma KB cells at concentrations ranging from 5 μg/mL to 100 μg/mL. Furthermore, ZnO-PIP NPs treatment increased the upregulation of crucial apoptotic genes, including BCL2, BAX, and P53, within the KB cells, unraveling the intricate mechanism of apoptotic activity. Conclusions This approach offers a multifaceted solution to combatting both oral infections and cancer, showcasing their potential for significant advancement in oral healthcare.

The Radix Bupleuri and Radix Paeoniae Alba herb-pair (RRH) are the most classic compatible drug pair for the treatment of hepatitis. However, the underlying mechanism remains unclear. Therefore, network pharmacology and molecular docking were conducted to investigate the prospective therapeutic constituents, targets, and pharmacological mechanisms of RRH in the treatment of hepatitis. The active components of RRH from the TCMSP database and disease-related targets from the OMIM, PharmGkb, GeneCards, TTD, and DrugBank databases were identified. The “drug-target-disease” network diagram and protein–protein interaction (PPI) network were constructed using Cytoscape (v3.8.0) and Online STRING 11.0. GO and KEGG pathway enrichment analyses were performed using R version 4.1.2, and molecular docking was performed to verify the results. We placed 176 overlapping cross genes into Online STRING 11.0 and obtained 14 core targets. A “Component-Target-GO-KEGG” network diagram was constructed, which was composed of 7 components, 14 targets, 10 biological processes, and 10 signal pathways. A total of 2413 GO biological processes and 174 KEGG pathways were explored for hepatitis treatment. Quercetin, kaempferol, isorhamnetin, and beta-sitosterol, which are the main bioactive components, were employed to bind the disease's hub targets, ensuring fulfillment of spatial and energy matching. The anti-hepatitis mechanism of RRH may be associated with several targets including RELA, AKT1, JUN, MAPK1, TP53, CCND1, MYC, NFKBIA, CDKN1A, and their respective signaling pathways. The main bioactive components in RRH, including quercetin, kaempferol, isorhamnetin, and beta-sitosterol, were used to bind the hub targets of the disease, which may provide insights into drug development for hepatitis.
