Description: YD277 is a novel small molecule derived from ML264, a KLF5 inhibitor that elicits cytotoxic effects in colon cancer cell lines. Krüpple-like factor 5 (KLF5) is a promising therapeutic target for TNBC. YD277 significantly induced G1 cell cycle arrest and apoptosis in MDA-MB-231 and MDA-MB-468 TNBC cells, independent of KLF5 inhibition. YD277 also reduced the protein expression levels of Cyclin D1, Bcl2 and Bclxl and promoted the expression of p21 and p27. YD277 (15 mg/kg) significantly suppressed the growth of MDA-MB-231 tumor xenografts in nude mice. These findings indicate that YD277 is a promising chemotherapeutic candidate for TNBC. Triple-negative breast cancer (TNBC) is an aggressive malignancy with poor clinical outcomes
