Immunopharmacology Comments
TYK2 was the first member of the Janus kinase family to be identified. It associates with the cytoplasmic domain of type I and type II cytokine receptors, where it phosphorylates receptor subunits and facilitates signalling downstream of the receptors for the p40-containing cytokines IL-12 and IL-23 via activation of STAT-dependent transcription factors. It also mediates Type I IFN-driven responses [34]. TYK2 activity mediates cytokine-driven immune and pro-inflammatory signalling pathways that are key components in the cycle of chronic inflammation that drives the pathophysiology of immune-mediated diseases including psoriasis [21] and arthritic psoriasis, systemic lupus erythematosus and inflammatory bowel diseases.

Small molecules that inhibit TYK2 are being actively developed as novel therapeutics for the above conditions [19,29]. TYK2 selectivity has been achieved by targeting the protein's pseudokinase (Jak homology 2 or JH2) domain [25,37], rather than the functional kinase (or JH1) domain which shares a high degree of homology across all members of the Janus kinase family and offers little selectivity. Identified molecules act as negative allosteric modulators (NAM) of TYK2 activity. One particular example of a clinical candidate TYK2 NAM is deucravacitinib (BMS-986165), which is an orally active compound that has progressed to Phase 3 clinical evaluation in patients with psoriasis [32], and is the first truly TYK2 selective inhibitor. Clinical trials are in earlier stages for a spectrum of chronic autoimmune diseases. Click here to link to ClinicalTrials.gov's full list of BMS-986165 studies. Nimbus Therapeutics are also developing allosteric TYK2 inhibitors (claimed in their patent WO2016138352 [10]), although no clinical leads have been disclosed (July 2021).
