Calmodulin is a calcium-sensing protein that regulates a wide array of proteins involved in diverse cellular functions. Ophiobolin B is a sesterterpenoid fungal phytotoxin that binds and irreversibly antagonizes calmodulin, producing cytotoxic and antimicrobial effects. It induces apoptosis in chronic lymphocytic leukemia cells with an LC50 value of 2 nM and in different zygomycetes with MIC values ranging from 25-50 µg/ml.{30257,30258}
