Abstract

Breast cancer is one of the most prevalent diseases among women and ranks among the top five leading causes of cancer-related deaths worldwide. Current therapeutic approaches remain suboptimal in addressing the highly aggressive progression of cancer cells. A simple method to initiate the drug discovery process is Quantitative Structure-Activity Relationship (QSAR) analysis. Previous experimental studies have reported that cyanopyridine derivatives exhibit potent inhibitory effects on PIM-1 kinase, a key regulator in MCF-7 human breast cancer cells. In this study, we performed QSAR analysis on structurally modified cyanopyridine derivatives to design novel anti-breast cancer agents. The research methodology included: (1) molecular geometry optimization using the PM3 semi-empirical method, (2) calculation of QSAR descriptors (hydrophobic, electronic, and steric parameters), and (3) rational molecular design based on the derived QSAR model. Optimizations and calculations were performed using HyperChem software. Multiple Linear Regression (MLR) analysis and external validation generated the best QSAR equation for Model 1: log (1/IC50) = 151.273 + 1884.726qC1 − 4663.478qC4 + 5431.564qC5 + 1501.074qN7 + 592.015qO10. This model exhibits better core statistical metrics, with an R = 0.868, R2 = 0.753, SEE = 0.272, R2ext = 0.9342, and Q2ext = 0.8717. In addition, statistical parameters of the Y-scrambling test indicate the robustness of the best QSAR model (average Rscramble = 0.3881; average R2scramble = 0.1558). A promising drug candidate was identified based on antiproliferative activity predicted by the best QSAR model. A subsequent in silico evaluation comprehensively assessed their pharmacokinetic and toxicity profiles. The results revealed that synthesized and designed derivatives successfully satisfied most critical pharmaceutical criteria. The pharmacokinetic profile of this compound was comparable to the native ligand (VRV), as well as established reference drugs like tamoxifen and doxorubicin. 2-[4-(5-Cyano-6’-fluoro-1-methyl-6-oxo-1,6-dihydro-[2,3’]bipyridinyl-4-yl)-2-methoxy-phenoxy]-N-phenyl-acetamide (8M) was considered the best potential drug candidate due to its high anti-breast cancer efficacy and relatively low toxicity. The molecular docking study demonstrates that the binding affinity of the designed cyanopyridine derivatives for the PIM-1 kinase receptor was in the range of −9.5 to −9.7 kcal·mol−1, which is comparable to that of doxorubicin (10.0 kcal·mol−1). Moreover, these values surpass the binding affinity of the native ligand (9.2 kcal·mol−1) and tamoxifen (8.0 kcal·mol−1). This finding was further corroborated by molecular dynamics simulations, which demonstrated the stability of the interactions. Therefore, these designed compounds have potential as novel anti-breast cancer drugs.

Abstract

This study addresses the increasing complexity of cross-border halal trade, where fragmented certification regimes and differing regulatory and fiqh-based approaches raise verification costs and weaken trust. The purpose of this research is to develop and evaluate a digital halal assurance framework that enables Artificial Intelligence (AI)–blockchain halal traceability to support cross-border certification harmonization by making compliance evidence interoperable, verifiable, and auditable. The study uses a qualitative multiple-case design involving regulators, certification bodies and auditors, manufacturers and suppliers, logistics providers, and laboratories. Data were collected through document analysis, semi-structured interviews, and expert review workshops, and analyzed using thematic analysis with cross-case synthesis to derive design requirements. Results show that harmonization relies on institutional arrangements for recognizing evidence; three outputs are pivotal: a shared minimum evidence baseline, a rule-based and updateable equivalence mapping, and a trust registry with accountability and revocation oversight. These elements also shape system architecture toward permissioned consortium governance. Interoperability is the main bottleneck because evidence is dispersed across heterogeneous formats; a minimum data set, selective disclosure, and a hybrid off-chain/on-chain architecture with standardized interfaces and schema versioning are needed to reduce manual reconciliation. Blockchain functions as an evidence engine that anchors audit trails, integrity proofs, and revocation-aware verification via smart contracts. The study concludes that harmonization requires aligning governance, data standards, and evidence mechanisms, and recommends phased implementation and support measures to avoid excluding small and medium enterprises.
