Acetylcholinesterase CAS:9000-81-1
Anticholinesterases are a class of drugs or chemicals that inhibit the activity of the enzyme acetylcholinesterase. Acetylcholinesterase is responsible for breaking down the neurotransmitter acetylcholine in the body. By inhibiting this enzyme, anticholinesterases increase the levels of acetylcholine, leading to increased cholinergic activity in the central and peripheral nervous systems.
The main therapeutic use of anticholinesterases is in the treatment of neurological disorders such as Alzheimer’s disease and myasthenia gravis. In Alzheimer’s disease, these drugs aim to enhance cholinergic neurotransmission and potentially slow down cognitive decline. In myasthenia gravis, anticholinesterases help improve neuromuscular transmission and muscle strength.
Other uses of anticholinesterases include the diagnosis and treatment of anticholinergic poisoning, specifically from certain insecticides or nerve agents. These substances can cause excessive stimulation of the muscarinic and nicotinic receptors, leading to symptoms like muscle weakness, tremors, and respiratory distress. Anticholinesterases can reverse these effects by increasing acetylcholine levels and competition with the toxic substances.

Rapamycin from Streptomyces hygroscopicus CAS:53123-88-9
Rapamycin is a naturally occurring compound isolated from the bacterium Streptomyces hygroscopicus. It has a wide range of biological activities and is primarily known for its immunosuppressive and anti-cancer properties.
Originally discovered as an antifungal agent, rapamycin has since been found to possess potent immunosuppressive properties, making it valuable in organ transplantation to prevent rejection. It does this by inhibiting the activation and proliferation of T-cells, a key component of the immune response.
Additionally, rapamycin has shown promising results in the treatment of various cancers. It works by inhibiting a protein called mTOR (mammalian target of rapamycin), which plays a critical role in cell growth and division. By blocking mTOR, rapamycin helps to control the unregulated growth of cancer cells.
