Quantitative analysis of the phytochemical composition showed high levels of primary metabolites: carbohydrates (45.11 ± 2.15 GLE mg/100 mg), proteins (28.13 ± 0.94 BSA mg/100 mg), and amino acids (13.25 ± 1.16 LE mg/100 mg). Ethyl acetate extracts had the highest concentrations of secondary metabolites, including phenolic content (122.52 ± 4.27 GAE mg/100 mg), total flavonoids (91.86 ± 2.65 QE mg/100 mg), and alkaloids (82.18 ± 0.72 COLE mg/100 mg). In addition, strong antioxidant activities were observed in the DPPH^• scavenging assay (IC₅₀ 11.51 ± 2.28 µg/mL), ABTS^·+ radical cation scavenging activity (97.42 ± 7.19 µM TE/g), and FRAP assay (14.34 ± 1.24 mM Fe(II)/mg). Based on preliminary analysis, the ethyl acetate extract was fractionated using thin-layer chromatography (TLC), yielding two distinct fractions with Rf values of 0.31 and 0.76. GC-MS analysis of these fractions identified 33 bioactive compounds. These fractions exhibited anticancer activity against the A549 lung cancer cell line, with IC₅₀ values of 47.25 µg/mL and 48.31 µg/mL, as determined by the MTT assay. Furthermore, absorption, distribution, metabolism, excretion, and toxicity (ADMET) studies on 25 selected compounds indicated favorable pharmacokinetic properties and drug-likeness. In silico molecular docking showed strong binding affinities of these bioactive compounds to the p21 protein, comparable to the synthetic drug Cisplatin-quercetin. The results highlight the potential of <i>O. latifolia</i> in anticancer therapy, particularly through modulation of the p21 pathway, supported by in vitro cytotoxicity assessments, molecular docking, and ADMET analysis.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-024-04167-4.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 1","pages":"19"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11662119/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142875818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MYC plays a critical role in regulating metabolism, differentiation, proliferation, cell growth, and apoptosis. Dysregulation of MYC is associated with poor prognosis and contributes to the development and progression of breast cancer. A particularly intriguing aspect of TNBC is its association with tumors in BRCA1 mutation carriers, especially in younger women. MYC may also contribute to resistance to adjuvant treatments. For TNBC, targeting MYC-regulated pathways in combination with inhibitors of other carcinogenic pathways offers a promising therapeutic approach. Several signaling pathways regulate TNBC, and targeting these pathways could lead to effective therapeutic strategies for breast cancer. Advances in genomic tools, such as CRISPR-Cas9, next-generation sequencing, and whole-exome sequencing, are revolutionizing breast cancer diagnoses. These technologies have significantly enhanced our understanding of MYC oncogenesis, particularly through CRISPR-Cas9 and NGS. Targeting MYC and its partner MAX could provide valuable insights into TNBC. Moreover, the therapeutic potential of targeting MYC-driven signaling mechanisms and their interactions with other oncogenic pathways, including PI3K/AKT/mTOR and Wnt/β-catenin, is increasingly recognized. Next-generation sequencing and CRISPR-Cas9 represent significant breakthroughs in genomic tools that open new opportunities to explore MYC's role in TNBC and facilitate the development of personalized treatment plans.

The bactericidal effects induced by NIR light indicate that the PEI/AS nanoparticles possess an efficiency that is five times greater than that of Ag₂S alone. A suggested antibacterial mechanism posits that the wrapping of PEI increases electrostatic interactions, thereby facilitating the attachment of Ag₂S nanoparticles to the bacterial surface. This process leads to the disruption of the outer membrane through the generation of localized heat and an increased concentration of reactive oxygen species (ROS), including superoxide anions (·O₂ ^-) and hydroxyl radicals (·OH). In addition, the mechanism involves the regulated release of Ag⁺ ions when exposed to NIR light irradiation. The combined action led to an over 95.79% elimination of bacteria at a concentration as low as 50 μg mL^-1, which can be primarily ascribed to the regulated photothermal effect induced by 808 nm near-infrared light irradiation, demonstrating exceptional photothermal conversion efficiency.
