Cinobufagin is a bufadienolide compound extracted from the dried venom secreted by the parotid glands of toads and one of the glycosides in the traditional Chinese medicine ChanSu, with potential antineoplastic activity. Cinobufagin has been shown to have clinical applications in cancer treatment as well as immunomodulatory and analgesic properties. Cinobufagin induces apoptosis of osteosarcoma cells through inactivation of Notch signaling. Cinobufagin induces autophagy-mediated cell death in human osteosarcoma U2OS cells through the ROS/JNK/p38 signaling pathway. Cinobufagin significantly relieved cancer pain in mice and raised their pain threshold, mainly upregulating the expression levels of beta-Endorphin and μ- opioid receptor in the hind paw tumor and adjacent tissue. In combination with gemcitabine-oxaliplatin cinobufagin was used in clinical trial for the treatment of locally advanced or metastatic gallbladder carcinoma.

In Vitro Use Guide

The survival rates of cinobufagin (0–300 nM) in 143B cells after 24, 48 and 72 h were investigated. Cinobufagin (100 nM) inhibited ~ 50% proliferation of 143 cells and the half-maximal inhibitory concentration (IC50) values were ~ 98–103 nM after 48 h treatment.
