Antineoplastic, anti-inflammatory and immunomodulating agent. Orally bioavailable potent ATP mimetic that inhibits both JAK1 and JAK2 with IC50 values of 2.7 and 4.5nM, respectively and is less selective for JAK3 (IC50=322nM). Affects DC differentiation and function, leading to impaired T cell activation. Used in the treatment of myeloproliferative neoplasms and psoriasis. Anticancer agent. Shown to induce apoptosis and autophagy. Potent and selective inhibitor of HIV-1 replication and virus reactivation in vitro. It is investigated against the spread of the SARS-CoV-2 (COVID-19).
