3 - (3R, 4R) - 4-methyl-3 - methyl - (7h pirrolo 2, 3-d pirimidin-4-il) - amine - piperidin-1-il} - 3-oxo-propionitrilo

摘要

It refers to the crystal salt form of 3 - (3R, 4R) - 4-methyl-3 - [methyl - (7h pirrolo [2, 3-d] pirimidin-4-il) - amine] - piperidin-1-il} - 3-oxo-propionyl, including X-ray derivatives of fine crystals expressed in degrees 2-o-5, 7, 16, 1, 20, 2 and 20.5. Its characteristic is that its initial temperature is between 199 ℃ and 206 ℃. It also refers to a kind of inhibiting the pharmacological synthesis of quinase protein, which helps to treat organ transplantation, sclerosis, arthritis, type 1 diabetes and other rejection related diseases.
