β-amanitin

β-Amanitin, a cyclic peptide toxin found in the poisonous Amanita phalloides mushroom, inhibits eukaryotic RNA polymerase II and III, thereby disrupting protein synthesis.

γ-Amanitin, an ADC (antibody-drug conjugate) cytotoxin isolated from mushrooms, inhibits RNA polymerase II, disrupting mRNA synthesis. It exhibits effects akin to those of α-Amanitin and β-Amanitin.

Mal-C6-α-Amanitin, an ADC (antibody-drug conjugate) linker drug, incorporates the powerful antitumor agent α-Amanitin, an inhibitor of RNA polymerase II, through the Mal-C6 linker, showcasing potent antitumor activity.

MC-VC-PABC-C6-alpha-Amanitin is an antibody-drug conjugate that combines the anticancer toxin alpha-Amanitin with the monoclonal antibody MC-VC-PABC-C6. Alpha-Amanitin, a potent inhibitor of RNA polymerase IIα, enables the conjugate to selectively target and recognize HER2-positive tumor cells, making it a valuable research tool in the study of breast and gastric cancers [1].

ε-Amanitin is a cyclic peptide obtained from various mushroom species. It exhibits a strong affinity for RNA polymerase II and effectively inhibits its activity.

Dideoxy-amanitin (compound 2), a derivative of α-Amanitin, functions as a potent, selective allosteric inhibitor of RNA polymerase II, demonstrating an inhibition concentration (IC50) of 74.2 nM [1].

alpha-Amanitin (alpha-Amanitin) is the lethal toxin in Trichoderma viride and acts in vivo via the enterohepatic circulation and transport system. alpha-Amanitin induces cell death and can be used in the synthesis of ADCs. alpha-Amanitin has been shown to induce cell death and can be used in the synthesis of ADCs.
