Macranthoside B
Based on 1 Customer Validation
Macranthoside B is an apoptosis inducer with in vitro and in vivo anticancer activity. Macranthoside B induces autophagy and ferroptosis in cancer cells. Macranthoside B induces intracellular ROS accumulation, activates AMPK, inhibits mTOR and P70S6 kinase phosphorylation, and modulates Bcl-2/Bax expression. Macranthoside B activates caspase-3, caspase-9, and the intrinsic caspase cascade, induces PARP cleavage/degradation, and inhibits NRF2 signaling. Macranthoside B disrupts iron homeostasis via NCOA4-dependent ferritinophagy, up-regulates Lip-ROS, reduces mitochondrial membrane potential, and activates the JNK pathway. Macranthoside B can be used for the research of ovarian cancer, hepatoma, gastric carcinoma, breast carcinoma, colon carcinoma, glioma, melanoma, adenocarcinoma of the esophagogastric junction, and cervical cancer.
