Biotoxin Library

90 compounds

Biotoxins, also referred to as natural toxins, are chemical substances produced by plants, animals, or microorganisms that exert toxic effects on other living organisms. Due to unique biological activities, biotoxins have been widely applied in molecular biology, physiology, pharmacology, and the clinical diagnosis and treatment of various human diseases, becoming an important source of natural drug development. Biotoxins can specifically bind to and interfere with intracellular signaling molecules or receptors, thereby altering cellular signaling processes. Leveraging this characteristic, biotoxins can be used to study the regulatory mechanisms of cellular signaling pathways. For example, neurotoxins such as snake venom peptides can be used to investigate the functional regulation of neurotransmitter receptors and ion channels. Additionally, biotoxins have demonstrated significant potential in drug development across various fields, including neurological diseases, cardiovascular diseases, anticoagulation, and anti-cancer therapies. With advancements in high throughput screening, structural optimization, and antibody-toxin conjugation technologies, numerous biotoxins or their structural analogs have been successfully brought to market, such as Ziconotide, Captopril, Bivalirudin, and Eptifibatide.

MCE offers 90 types of biotoxins, including neurotoxins, cardiotoxins, mycotoxins, and more.
