Definition: Pseudoviperine is a synthetic drug used for its potential therapeutic properties in the treatment of certain types of cancer. It is a molecule that mimics the structure and activity of the naturally occurring substance phevolin, which is found in many plants. Pseudoviperine was first synthesized in 1972 by researchers at the University of California, Berkeley. The drug's mechanism of action involves inhibiting a protein called cyclin-dependent kinase 5 (CDK5),
