Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer. Many studies have shown a significant increase in the marker signal of the receptor for advanced glycation end-products (RAGE) with the malignant progression of tumor growth, metastasis and recurrence of breast cancer, including TNBC of primary tumors and lymph node metastases. Azeliragon is a RAGE inhibitor and it has been shown to actively inhibit the TNBC cell line, SUM149 (IC50 = 5.292 ± 0.310 μM). In order to develop a new anti-TNBC agent, we designed, synthesized and screened 26 Azeliragon triazole analogues to determine their anti-TNBC activities in vitro. The most active compound was KC-10 with an IC50 value of 0.220 ± 0.034 μM.
