Tofacitinib, with the CAS NO.477600-75-2, has the synonyms of 3-((3R,4R)-4-Methyl-3-(methyl(7H-pyrrolo(2,3-d)pyrimidin-4-yl)amino)piperidin-1-yl)-3-oxopropanenitrile; CP 690550; 3-Piperidinamine, 1-(cyanoacetyl)-4-methyl-N-methyl-N-1H-pyrrolo(2,3-d)pyrimidin-4-yl-, (3R,4R)-. Tofacitinib is a drug discovered and developed by Pfizer. Tofacitinib is a selective inhibitor of Janus kinase (JAK) enzymes. JAKs mediate signaling by surface receptors for several important cytokines that are fundamental to the propagation of inflammation in RA.
