However, its effects on triple-negative breast cancer (TNBC), a very aggressive subtype lacking targeted treatments, remain poorly studied. This study evaluates the anticancer activity of A. sieberi extracts against the MDA-MB-231 TNBC cell line, comparing results with hormone receptor-positive MCF-7 cells. Aerial parts of A. sieberi were extracted using ethanol and methanol and then chemically characterized via gas chromatography/mass spectrometry (GC/MS) to identify bioactive compounds. Cytotoxic effects were assessed using cell viability assays, while apoptosis induction was examined through flow cytometry (Annexin V/propidium iodide staining), caspase-3/-7 activation assays, and mitochondrial membrane permeabilization visualized using confocal microscopy. Western blotting analyzed the expression levels of apoptotic proteins. In silico molecular docking simulations explored the interactions between phytochemicals and apoptosis-regulating proteins. A. sieberi extracts exhibited higher cytotoxicity against MDA-MB-231 cells than against MCF-7 cells, with lower IC<sub>50</sub> values. Treatment of TNBC cells induced apoptosis, evidenced by increased caspase activity, mitochondrial membrane permeabilization, elevated Bax, and decreased Bcl-2 expression. Additionally, colony formation assays demonstrated a significant reduction in tumorigenic potential. Computational analyses indicate that β-sitosterol and stigmasterol, among the main compounds, exhibited strong interactions with apoptosis regulators by docking with Bcl-2, supporting their promising anticancer potential. A. sieberi extracts induce potent apoptosis and exert anti-tumour effects in TNBC cells, highlighting their potential as sources of novel anticancer agents. Further isolation and characterization of active constituents are warranted for therapeutic development.</p>","PeriodicalId":49257,"journal":{"name":"Saudi Pharmaceutical Journal","volume":"33 6","pages":"46"},"PeriodicalIF":4.3,"publicationDate":"2025-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12644357/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145589702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BC@HS15/DSPE-PEG2000-L-Val or free BC was administered via eye drops to benzalkonium chloride (BAC)-induced dry eye mice. Corneal and conjunctival tissues were assessed for anti-dry eye efficacy. BC concentrations in cornea, conjunctiva, aqueous humor, and ocular plasma were quantified using LC-MS/MS. Noncompartmental pharmacokinetic parameters (AUC, Tmax) were calculated using DAS 2.0 software. The method demonstrated excellent linearity (0.50-500.00 ng/mL, r > 0.9905), precision (RSD < 10%), and accuracy (± 13%). Compared to free BC, BC@HS15/DSPE-PEG2000-L-Val significantly increased tear secretion, reduced MMP-3/MMP-9 expression, and preserved corneal epithelium integrity.

There is a need to shift the regulatory framework of community pharmacies to be under the Saudi Food and Drug Authority (SFDA) to align with global standards. However, there is limited knowledge about the perceptions of pharmacists regarding the current regulatory framework in community pharmacies in the Kingdom of Saudi Arabia (KSA).</p><p><strong>Objectives: </strong>This study aims to assess pharmacists' knowledge, perceptions, and preferences regarding the current regulatory framework of community pharmacies and feasibility of transitioning regulatory oversight to SFDA.</p><p><strong>Methodology: </strong>A cross-sectional survey design was used to assess the regulation of community pharmacies in Saudi Arabia. The sample consisted of 139 pharmacists from various sectors, selected through random sampling. A structured questionnaire focusing on regulation, awareness, and perceptions was distributed online. The questionnaire's validity and reliability were ensured through expert review. Descriptive statistics in SPSS were used for data analysis.</p><p><strong>Results: </strong>The survey findings revealed a diverse representation across the pharmaceutical sector. Hospital pharmacists formed the largest group (37.4%, n = 52), followed by regulatory field workers from the Ministry of Health (21.6%, n = 30) and SFDA (20.1%, n = 28), pharmaceutical industry professionals (11.5%, n = 16), and community pharmacists (9.4%, n = 13). Most participants (51.8%, n = 72) had 1-5 years of experience, while 31.7% (n = 44) had 6-10 years, and 16.5% (n = 23) had more than 10 years of experience. Regarding current regulatory oversight, the majority (82.7%, n = 115) reported being under MOH regulation, with 12.2% (n = 17) under SFDA oversight. The study revealed high awareness of current regulations (77.0%, n = 107), though most participants (62.6%, n = 87) expressed dissatisfaction with the current regulatory framework. Notably, 77.0% (n = 107) preferred SFDA as the future regulator, and 80.6% (n = 112) believed SFDA would perform better in regulating the sector. Most participants demonstrated strong agreement with proposed regulatory changes, with 78.4% (n = 109) agreeing to P1 and 79.1% (n = 110) to P4 statements regarding regulatory reform.</p><p><strong>Conclusion: </strong>The study reveals strong sector-wide preference among pharmaceutical professionals for transitioning community pharmacy regulation to SFDA, driven by dissatisfaction with current MOH oversight. This consensus across all professional categories and experience levels indicates practitioners' expectations that SFDA regulation would enhance pharmaceutical service quality and regulatory effectiveness in Saudi Arabia.</p>","PeriodicalId":49257,"journal":{"name":"Saudi Pharmaceutical Journal","volume":"33 5","pages":"36"},"PeriodicalIF":4.3,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12491131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
