gamma-Lumicolchicine is three, alpha, beta, and gamma isomers of ultraviolet degradation products of colchicine that lack many of the physiological actions of the parent; used as experimental control for colchicine actions.
Trimethylcolchicinic acid methyl ether (HAN 76504), an antimitotic agent, blocks microtubule assembly by attaching to tubulin and inhibiting its polymerization. It enhances tubulin's intrinsic GTPase activity, induces apoptosis across various normal and tumor cell lines, and activates the JNK SAPK pathway. Currently unnamed, it is referred to by a provisional code name in line with MedKoo Chemical Nomenclature (https: www.medkoo.com page naming) for ease of communication.
