Drug-loaded LCNPs were prepared using glyceryl monooleate (GMO) as the lipid phase and Poloxamer-407 as the stabilizer via a high-energy emulsification followed by probe sonication. A 3² full factorial design was applied to systematically optimize critical formulation variables affecting particle size and entrapment efficiency. The optimized LCNs of dispersions were combined to obtain the final formulation (PLNs-9) and characterized for morphology (TEM), thermal behaviour (DSC), crystallinity (XRD), and drug–excipient compatibility (FTIR). The PLNs-9 exhibited nanoscale particle size (144.2 ± 5.3 nm) with high entrapment efficiencies (PCB 95.54 ± 3.57%, LTZ 84.35 ± 2.86%). Solid-state analyses confirmed molecular dispersion of drugs within the lipid matrix. In vitro release studies demonstrated sustained drug release under physiological conditions. Cytotoxicity studies in MCF-7 breast cancer cells revealed significantly enhanced antiproliferative activity of PLNs-9 (IC₅₀ = 10.56 ± 1.34 µg; <i>p</i> &lt; 0.001) compared with individual drugs and their physical combination, accompanied by increased apoptotic cell populations and pronounced G2/M phase arrest. Pharmacokinetic evaluation demonstrated prolonged systemic circulation and approximately 2-fold enhancement in relative bioavailability compared to both PCB and LTZ. These findings suggest that the developed PLNs-9 containing PCB and LTZ combination represents a promising synergistic nanotherapeutic platform for breast cancer management.</p></div>","PeriodicalId":656,"journal":{"name":"Journal of Pharmaceutical Innovation","volume":"22 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While monoclonal antibodies targeting CD38 have improved clinical outcomes, small-molecule inhibitors remain scarce, limiting alternative therapeutic strategies. In this study, we employed a comprehensive in silico approach to identify drug-like, non-toxic marine Cyanobacterial metabolites as promising potential CD38 inhibitors. A total of 1085 MM-associated genes were intersected with 357 CD38-interacting genes to identify 207 MM-associated targets, which were enriched in immune-regulatory pathways. The CD38 binding pocket was characterized, and molecular docking screened Cyanobacterial metabolites for binding affinity and drug-likeness, identifying top candidates compliant with Lipinski, Ghose, Veber, Egan, and Muegge rules. Based on binding affinity, the selected drug-like, non-toxic metabolites (CyanoMetDB_1359, CyanoMetDB_2811, and CyanoMetDB_2812) exhibited favorable interactions with key residues, including TRP125, LEU145, TRP176, and THR221, overlapping with co-crystallized ligand interactions. Molecular dynamics simulations over 200 ns revealed stable protein-ligand complexes, with consistent RMSD, RMSF, Rg, SASA, distance, and hydrogen-bond profiles. Extensive principal component analysis and free energy landscapes confirmed conformational stability and minimal fluctuation. MM-PBSA calculations indicated favorable binding free energies, with residue-based decomposition suggesting critical stabilizing interactions. Collectively, this study identifies rare, marine-derived small-molecule candidates capable of effectively targeting CD38, bridging marine natural product chemistry with MM therapeutics. These findings provide a foundation for future experimental validation and development of small-molecule CD38 inhibitors derived from natural sources, with potential anti-myeloma activity.</p></div>","PeriodicalId":656,"journal":{"name":"Journal of Pharmaceutical Innovation","volume":"22 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
