JAK Inhibitors Overview
Janus kinase (JAK) inhibitors are small molecules, typically around 400 Da in size, that can be administered orally. JAKs are phosphotransferase enzymes that associate with the intracellular regions of cytokine receptors, facilitating signal transmission to activate immune responses. Cytokines that utilize JAKs for signaling include various interleukins, interferons, colony-stimulating factors, and hormone-like cytokines such as erythropoietin. These cytokines interact with receptors that signal through different combinations of four JAKs—JAK1, JAK2, JAK3, and TYK2.
First-generation JAK inhibitors, also known as jakinibs, such as tofacitinib and baricitinib (as well as oclacitinib for canine use), inhibit multiple JAKs simultaneously, thereby blocking a broad spectrum of cytokines. These pan-JAK inhibitors are being explored as potential treatments for numerous autoimmune conditions.
The JAK-STAT signaling pathway is employed by type I and II cytokine receptors, along with receptors for interferons and growth factors. Since these receptors lack intrinsic enzymatic activity, they rely on JAKs for downstream signaling and subsequent gene expression regulation. The name "Janus" is derived from the Roman god of doorways, symbolizing JAKs' role in transmitting signals from the cell surface to the interior. Each cytokine receptor is typically associated with a specific pair of JAKs, often forming heterodimers.
Upon cytokine binding, the receptors undergo cross-linking, triggering transphosphorylation between the associated JAKs. These activated JAKs then phosphorylate the receptor’s intracellular tail, creating a docking site for STAT (Signal Transducer and Activator of Transcription) proteins, which are normally present in the cytoplasm. The JAKs phosphorylate these STATs, prompting them to dissociate from the receptor, form homo- or heterodimers, and migrate to the nucleus, where they function as transcription factors to regulate gene expression. In mammals, there are seven STAT proteins, each associated with distinct signaling pathways, similar to JAKs.
Dysregulation of JAK activity—whether through increased or reduced kinase function—can contribute to various pathological conditions, including immunodeficiencies, inflammatory disorders, hematological abnormalities, autoimmune diseases, myeloproliferative syndromes, and increased susceptibility to infections. JAK dysregulation can result from gene translocations, inherited or somatic point mutations, receptor alterations, or changes in regulatory proteins such as SOCS or phosphatases.
The development of JAK inhibitors has revolutionized therapeutic approaches for a wide range of conditions, from malignancies to autoimmune diseases. Initially introduced to treat rare hematologic disorders, these inhibitors are now expanding into broader applications, including cancer and common autoimmune diseases.
Given the strong connection between JAK activity and various diseases, there is growing interest in designing JAK-specific inhibitors for treating myeloproliferative disorders and cancers or as immunosuppressive agents. Advances in structural biology have significantly contributed to the rational design of these inhibitors, and in recent years, crystal structures of all enzymatically active JAK kinase domains have been elucidated in complex with various ATP-competitive inhibitors.
