Breast cancer is the most prevalent cancer among women globally, characterized by the uncontrolled growth of breast cells, and remains a leading cause of cancer-related morbidity and mortality. It can occur in both men and women, though it is significantly rarer in men. The multifactorial nature of breast cancer involves genetic mutations, hormonal influences, and complex cellular signalling pathways. The disease is typically classified into different subtypes based on hormone receptor status, which influences treatment decisions. Early detection through regular screening, such as mammograms, and awareness of symptoms significantly improve prognosis. Treatment options vary based on the stage and type of breast cancer and may include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy. We aimed to design novel compounds based on reported active pharmacophoric features and validate them through molecular modelling. These designed compounds were then synthesized and characterized. Finally, a biological evaluation of the synthesized compounds was performed to assess their efficacy.
Thirty compounds were designed based on a literature survey. Out of these compounds, twelve compounds were found good on the docking studies, and these twelve new derivatives (RD 01-12) were synthesized and subjected to in silico, in vitro (EGFR assay), and ADMET profiling to identify the most potent compound.
All 12 compounds were synthesised and characterised. Out of 12 compounds, RD-09 emerged as the most potent enzymatic assay with an IC50 value of 1.21 ± 0.03 µM, confirmed by docking studies; it possessed a docking score of -7.302 against the EGFR receptor. These compounds were further characterized using IR, 1H NMR, and mass spectrometry.
Based on pharmacophoric features, twelve triazine-4-thiazolidinone derivatives (RD 01-12) were designed, synthesized, and evaluated for their potential as EGFR-2 inhibitors, specifically targeting triple-negative breast cancer (TNBC). Among 12 synthesised compounds, compound RD-09 demonstrated the most significant activity with an IC50 value of 1.21 ± 0.03 µM. Docking studies further supported its binding interaction with the catalytic domain of the EGFR receptor. The combined results from in vitro, in silico, and ADMET profiling suggest that RD-09 holds promise as a leading compound for further development in the treatment of TNBC.
