Abstract

Importance of the field: JAK2 is one of the most promising targets against neoplastic growth. A somatic mutation (V617F) resulting in enhanced JAK2 kinase activity can be frequently found in patients with serious myeloproliferative neoplasms such as polycythemia vera, essential thrombocythemia and primary myelofibrosis. Preclinical results strongly support that JAK2 inhibitors could be effectively used in these indications. Pharmaceutical companies and academic groups have developed a number of potent JAK2 inhibitors during the last decade. Tolerability and effectiveness of the most promising compounds are currently being investigated in clinical trials. Areas covered in this review: In this paper, we aim to give a comprehensive review of the currently available patent literature of JAK2 inhibitors. What the reader will gain: We tried to collect the published core structures possessing JAK2 inhibitory potency including compounds developed by academic and industrial research groups. We review the currently available patent literature as well as the key papers containing additional information about the described JAK2 inhibitors. Clinical status data were collected by searching the Prous Integrity and Pharmaprojects databases. Take home message: The significant number of JAK2 inhibitors published and numerous clinical trials involving these compounds suggest that some of them might be approved in the next few years and can serve as novel drugs for the treatment of JAK2-dependent pathologies. © 2010 Informa UK Ltd.
