Class/mechanism: Kinase inhibitor of Janus Associated Kinases (JAKs) JAK1 and JAK2. Modulates gene expression by interfering with the JAK signaling pathway, which involves recruitment, activation, and localization of STATs (signal transducers and activators of transcription) to cytokine receptors and the nucleus.
