Description

Viscumin is a potent protein toxin derived from the mistletoe plant, *Viscum album*, with the CAS registry number 83590-17-4. This compound is of significant interest in biomedical research due to its specific biological activity as a ribosome-inactivating protein (RIP). It is primarily utilized by research institutions and pharmaceutical developers focused on oncology, immunology, and targeted therapeutic applications.

Application

• Biomedical Research: Used as a tool compound to study mechanisms of protein synthesis inhibition and ribosome function.
• Oncology Studies: Investigated for its cytotoxic properties and potential in developing antibody-drug conjugates (ADCs) and other targeted cancer therapies.
• Immunology Research: Explored for its immunomodulatory effects and potential application in immunotherapy protocols.
• Cell Biology: Employed in studies of apoptosis (programmed cell death) and intracellular trafficking.
• Toxicology Profiling: Serves as a reference standard in assessing the toxicity and specificity of plant-derived RIPs.
• Pharmaceutical Development: Used in pre-clinical research for evaluating novel drug delivery systems and therapeutic efficacy.
