Triple-negative breast cancer (TNBC) is a subtype of breast cancer with high mortality and drug resistance and no targeted drug available at present. Compound , a staurosporine alkaloid derived from sp. NBU3142 in a marine sponge, exhibits potent anti-TNBC activity. This research investigated its impact on MDA-MB-231 cells and their drug-resistant variants. The findings highlighted that compound inhibits breast cancer cell migration, induces apoptosis, arrests the cell cycle, and promotes cellular senescence in both regular and paclitaxel-resistant MDA-MB-231 cells. Additionally, this study identified mitogen-activated protein kinase kinase kinase 11 (MAP3K11) as a target of compound , implicating its role in breast tumorigenesis by affecting cell proliferation, migration, and cell cycle progression.
三阴性乳腺癌（TNBC）是一种死亡率高且耐药性强的乳腺癌亚型，目前尚无靶向药物。化合物是一种来源于海洋海绵中的 sp. NBU3142 的新型星形孢菌素生物碱，具有很强的抗 TNBC 活性。本研究探讨了其对 MDA-MB-231 细胞及其耐药变体的影响。研究结果表明，化合物 抑制乳腺癌细胞迁移，诱导细胞凋亡，使细胞周期停滞，并促进正常和紫杉醇耐药的 MDA-MB-231 细胞衰老。此外，本研究还确定丝裂原活化蛋白激酶激酶激酶 11（MAP3K11）是化合物的靶点，表明其通过影响细胞增殖、迁移和细胞周期进程在乳腺癌发生中起作用。
