Telocinobufagin (TCB), a bufadienolide extracted from Bufo paracnemis parotoid glands, shows a reversible local anesthetic action, similar to BUPI, however, without cardiac toxicity in vitro. [1]
Telocinobufagin is a novel endogenous digitalis, exhibits elevated plasma levels in patients with terminal renal failure.[2]
Telocinobufagin and marinobufagin have antimicrobial activity, the minimum inhibitory concentrations of telocinobufagin and marinobufagin were, respectively, 64.0 and 16.0 microg/mL for E. coli and both 128 microg/mL for S. aureus; they also promote an increase of the contraction force in isolated frog ventricle strips.[3]
Telocinobufagin has potential immune system regulatory effects, suggests that it could be developed as a novel immunotherapeutic agent to treat and other immune-mediated diseases, and it may become a new immunomodulatory agent in many regions.[4]
Telocinobufagin can enhance the Th1 immune response and protect against Salmonella typhimurium infection .[5]
Telocinobufagin can induce colon cancer cell apoptosis by oxidative stress and apoptosis pathway.[6]
