Abstract Cancer remains a severe global health problem, with its incidence constantly increasing.. Among many varieties of cancer, breast cancer persists as a prevalent global health concern, with its occurrence continually ascending. Among women, breast cancer is a significant cause of illness and death globally. This study examined the antioxidant and anticancer effects of two resynthesized benzoxazine derivatives, OBOP‐01 and OBOP‐02, on human breast cancer cells. The chemicals investigated had intense antioxidant action against DPPH, H 2 O 2 , and ABTS free radicals. Furthermore, we evaluated cell viability by converting yellow MTT (3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetrazolium bromide) into purple formazan, dependent on mitochondrial function. Both compounds had IC 50 values of 1.52±0.02 mM and 1.72±0.02 mM respectively. Moreover, toxicity predictions using the ProTox‐III webserver showed that the benzoxazines studied have lower LD50 values compared to doxorubicin, suggesting greater safety. We also used Density Functional Theory (DFT) to analyze OBOP‐01 and OBOP‐02′s electrical interactions and properties. Gaining insight into these interactions is essential for understanding the compounds′ potential applications and properties. According to theoretical studies using molecular docking, the derivatives may interact with estrogen receptor alpha (ERα) (ID: 7NDO), a key target molecule in the development of breast cancer. Additionally, the complex OBOP‐01 – ERα′s molecular dynamics simulations were conducted for 100 nanoseconds. These simulations revealed essential details regarding the complex's dynamic behavior in a physiological system.
