10-Demethoxy-10-methylthiocolchicine - Introduction
Thiocolchicine is a compound from the colchicine family with a colchicine-like structure. Its chemical name is (7s)-N-[(7s)-3,4-dimethoxyphenyl]-5,6,7,8-tetrahydro-1,2,3,10-tetramethoxy-6, 7-dimethy1-n-(sulfoxymethyl) benzo[a]heptalene-4a-carboxamide.
The properties of Thiocolchicine are similar to colchicine. It is a white crystalline solid. It is almost insoluble in water at room temperature, but soluble in organic solvents such as ethanol, dimethyl sulfoxide and acetonitrile. It has the characteristics of active alkaline and black denaturation.
Thiocolchicine has a wide range of applications in the field of medicine. It is a semisynthetic derivative of colchicine, which has antitumor and anti-inflammatory effects. The cell division process can be blocked by inhibiting microtubule polymerization, thereby inhibiting the proliferation of cancer cells. In addition, Thiocolchicine is also used to treat inflammatory diseases such as arthritis and orthopedic conditions.
Regarding the preparation method, the preparation method of Thiocolchicine mainly introduces a sulfur group by reacting colchicine with a thioacylating reagent. This reaction results in thiolylation with the departure of the phthalimide at the 4a position to form Thiocolchicine.
When using Thiocolchicine, you need to pay attention to security issues. It is a potentially toxic substance with significant cytotoxicity and neurotoxicity. Contact with the skin or inhalation of its dust may cause irritation and injury. Appropriate personal protective equipment, such as gloves and protective glasses, should be used to avoid contact. At the same time, it should be operated in a well-ventilated area to avoid inhaling dust.
