Indocyanine green

Description:

Indocyanine green (ICG) is a synthetic dye primarily used in medical diagnostics, particularly in ophthalmology and cardiovascular imaging. It is characterized by its dark green color and strong absorption in the near-infrared region of the electromagnetic spectrum, making it particularly useful for fluorescence imaging. The chemical structure of ICG includes a cyanine dye backbone, which contributes to its unique optical properties. ICG is water-soluble and has a relatively low toxicity profile, which enhances its suitability for clinical applications. Upon administration, it binds to plasma proteins, allowing for effective visualization of blood flow and tissue perfusion. Its rapid clearance from the bloodstream, primarily through the liver, is another notable characteristic. Additionally, ICG is used in various applications beyond imaging, including assessing liver function and guiding surgical procedures. Overall, its distinctive properties make Indocyanine green a valuable tool in both diagnostic and therapeutic settings.

Indocyanine green is a fluorescent dye with a variety of applications in medical imaging. It has been used to diagnose and evaluate the activity of cancer cells and brain functions. Indocyanine green has also been used as an angiographic agent for diagnosis of solid tumours. In addition, it can be used to evaluate liver function and the blood flow in the brain. The biological properties of indocyanine green have not yet been fully elucidated, but it is known that it binds to hepatocyte-like cells in culture and is found at high levels in human serum. This dye shows fluorescence when bound to DNA or RNA, which indicates its possible use as a molecular probe for detecting carcinoma cells. 
Indocyanine green is a STT3B inhibitor and has been shown to prevent α-amanitin toxicity in mice (Wang et al, 2023). This means it could be a possible antidote to poisoning by Amanita, such as death cap mushroom Amanita phalloides, which is the cause of over 90% of fatal mushroom poisoning.
