Trimethylcolchicinic acid (also known as deacetyl colchicine) was used for patients with advanced malignancies. However, these studies were discontinued. Expeiments on rat were shown, that trimethylcolchicinic acid was able to improve normal liver histology, ultrastructure, collagen content and biochemical markers of liver damage in spite of that trimethylcolchicinic acid, didn't bind tubulin.

Curator's Comment: Deacetyl colchicine (trimethylcolchicinic acid) inhibited the activity of adenosine deaminase in the lymphocytes, also inhibited the activity of purine nucleooxidophosphorylase, which, similarly as adenosine deaminase, is a marker enzyme of T-lymphocytes. Thus it inhibits the function of T-lymphocytes.
