Cynanchum otophyllum Schneid．

Caudatin is an orally active and brain-penetrant C-21 steroidal found in Cynanchum bungei decne with a variety of biological activities. Caudatin can inhibit cell proliferation, migration, invasion, cause cell phase arrest, induce apoptosis, autophagy, ROS prodution and loss of mitochondrial membrane potential. Caudatin activates PARP, caspase-3, -7, -9, upregulates pro-apoptotic Bad and Bax and downregulates anti-apoptotic Bcl-2 and Bcl-XL. Caudatin suppresses VEGF, FAK phosphorylation, upregulates p21, p27, DR5 protein expression, activates the p38 MAPK, JNK and PPARα/TFEB-mediated autophagy-lysosomal signaling pathways. Caudatin can be used for the research of cancer, inflammation and neurological disease, such as glioma and Alzheimer's disease.
