Chunyu Gao, Hongbo Teng, Wenxin Zhang, Yaru Zhao, Chunguo Cui, Zerbo Patrice, Liyan Wang, Yan Zhao
TL;DR
This study develops a new compound, I-27, that effectively targets and kills triple-negative breast cancer cells by inhibiting tumor growth and inducing cell death.
Contribution
The study introduces a novel anti-TNBC drug candidate with a dual mechanism of action, targeting both tumor angiogenesis and apoptosis.
Findings
Compound I-27 showed strong cytotoxicity against MDA-MB-231 TNBC cells with an IC50 of 1.02 μM.
It inhibits tumor angiogenesis via the ID1/TSP-1 pathway and induces apoptosis through the PI3K/AKT/FoxO1 pathway.
In vivo tests demonstrated reduced tumor volume and lung metastasis in mouse models.
Abstract
Due to the lack of effective treatment methods and targeted drugs, triple-negative breast cancer (TNBC) is not only difficult to treat clinically, but also has a poor prognosis for patients. This study aims to develop novel anti-TNBC drug candidates by designing 90 derivatives of 3,4-seco-lupane triterpene derivatives, a natural product of the genus Eleutherogenus. Firstly, 90 derivatives were synthesized and screened, and the compound I-27 showed excellent cytotoxicity (IC50=1.02 μM) for MDA-MB-231 cells for further activity verification. Then in vitro tests were carried out to detect the effects of the compound on the proliferation, migration, invasion and apoptosis of TNBC cells. With the help of transcriptomics, the mechanism of action was explored and verified. At the same time, its inhibitory effect on tumor volume and lung metastasis was verified through a mouse model of in vivo…
