Abstract
Breast cancer (BC) is a significant public health concern globally. Triple-negative breast cancer (TNBC) is considered the most challenging type, as it is defined by an absence of estrogen and progesterone receptor expression, along with a lack of HER2 overexpression. In the current study, we developed a novel thymoquinone (TQ), TQFL19, to control TNBC progression. Purpose: The current study aimed to investigate the anticancer potential of a newly synthesized TQFL19 against TNBC. Study design: To achieve our research goals, we meticulously developed both in vitro and in vivo studies focused on TNBC cell growth, metastasis, and invasion. Results: Characterization and ADMET properties prediction of TQFL19 were first performed before treating TNBC cells. TQFL19 exhibited more potent cytotoxicity than TQ against 4T1, BT-549, and MDA-MB-231 cells and induced apoptosis of 4T1 and MDA-MB-231, besides cell cycle arrest of MDA-MB-231. In vivo mice allograft of 4T1 revealed the ability of TQFL19 to hinder the growth, migration, and metastasis of TNBC cells. Conclusions: The results suggest that TQFL19 potentially inhibited TNBC growth, metastasis, and invasion. The results conclude that TQFL19 could be a viable candidate for TNBC therapy.
