Ligand References Clinical and Disease comments
Immuno Disease Comments: Phase 2 clinical candidate for moderate to severe UC- see NCT02589665.
Clinical Use: Phase 2 clinical trials which will evaluate mirikizumab (as research code LY3074828) in Crohn's disease (NCT02891226), ulcerative colitis (NCT02589665) and plaque psoriasis (NCT02899988) patients are underway. | View clinical data
Bioactivity Comments: Mirikizumab (Antibody I) binds monkey IL-23 with a Kd of 0.056nM, and rabbit IL-23 with a Kd of 53nM, but does not bind rat or mouse IL-23 or human IL-12, IL-27 or IL-35 [2]. Antibody I blocks binding of IL-23 to the IL-23R in vitro, but does not inhibit IL-23 binding to IL-12Rβ1 (the other subunit of the functional IL-23R heterodimer). Effects of Antibody I in vivo are described in the associated patent documentation [2]. | View biological activity
Immuno Disease Comments: Approved drug for UC treatment and symptom prophylaxis.
Clinical Use: Mesalazine is used to treat active ulcerative colitis and to prevent symptom recurrence. It may also be used for the management of other types of inflammatory bowel disease (e.g. Crohn's disease). | View clinical data
Immuno Disease Comments: Phase 2 clinical candidate for active UC- see NCT03235752.
Clinical Use: A Phase 2 clinical trial evaluating olamkicept (using research code TJ301) in patients with active ulcerative colitis is registered with but is not yet recruiting paticipants (as of December 2017-see NCT03235752). | View clinical data
Immuno Disease Comments: Glucocorticoid drug used to treat many inflammatory condtions including UC.
Clinical Use: This drug used as an antiinflammatory or immunosuppressive agent and is indicated for the treatment of various inflammatory pathologies, including acute asthma, suppression of inflammatory and allergic disorders, ulcerative colitis, Crohn's disease, idiopathic thrombocytopenic purpura, rheumatoid arthritis, polymyalgia rheumatica, systemic lupus erythematosus and chronic obstructive pulmonary disease (COPD). | View clinical data
Immuno Disease Comments: A corticotropin used to treat the symptoms of many inflammatory disorders including UC
Clinical Use: Corticotropin is used to treat the symptoms of many allergic disorders, psoriasis and other skin conditions, eye conditions, arthritis, lupus, multiple sclerosis, ulcerative colitis and breathing disorders, for example. This peptide is also used to diagonse adrenocortical insufficiency. | View clinical data
Bioactivity Comments: Although we have recorded affinity data for ACTH at melanocortin receptors 1, 3, 4 and 5, affinity data for the human melanocortin receptor 2, the peptide's primary target, is lacking. As a peptide mimetic of ACTH we would expect corticotropin to have similar affinities to the endogenous peptide. | View biological activity
Immuno Disease Comments: Approved monoclonal antibody therapy for UC.
Clinical Use: Used in the management of rheumatoid arthritis (in combination with ), ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, Crohn's disease [29] and ulcerative colitis. | View clinical data
Bioactivity Comments: Infliximab has been reported to induce an anti-chimeric antibody response in almost 15% of Crohn's disease patients (47 tested) [23]. This indicates that as predicited, humans can mount an immune response to whole murine variable domains, and is the underlying rationale promoting the development of clinical antibodies with variable domains with more human character (i.e. humanised or fully human monoclonal developments). | View biological activity
Immuno Disease Comments: An anti-TNFα therapy approved for CD.
Clinical Use: Used in adults with various inflammatory conditions [34] e.g. moderate to severe active rheumatoid arthritis [11], active psoriatic arthritis, active ankylosing spondylitis and moderate to severe ulcerative colitis. | View clinical data
corticotropin zinc hydroxide
Immuno Disease Comments: Historically used to treat UC, with use now discontinued.
Clinical Use: Historical clinical uses include the treatment of ulcerative colitis and other colonic disorders [22] and therapy of some collagen diseases [1]. | View clinical data
Immuno Disease Comments: Approved drug for UC.
Clinical Use: Used to reduce organ rejection in transplant patients and to treat autoimmune diseases such as rheumatoid arthritis, Crohn's disease, lupus erythematosus and ulcerative colitis. | View clinical data
Bioactivity Comments: Azathioprine is reported to inhibit peptidylarginine deiminase 4 (PADI4), albeit with very low in vitro affinity [12]. PADI enzymes catalyze the hydrolytic deimination of protein arginine to produce protein citrulline and ammonia [10] and cause chromatin decondensation. Dysregulated PADI4 activity may be involved in cancer progression as it is overexpressed in many malignant tumours, where enhanced chromatin decondensation is involved in promoting pluripotency and stem cell maintenance. | View biological activity
Immuno Disease Comments: Approved therapeutic for UC.
Clinical Use: Approved to treat adult patients with moderate to severe ulcerative colitis or moderate to severe Crohn‘s disease. | View clinical data
Bioactivity Comments: In vitro, vedolizumab inhibits specific binding of α4β7 +ve lymphoma cells to immobilised MADCAM1 or fibronectin with IC50 values of 0.39nM and 0.14nM respectively [25]. Soler et al. (2009) also show by FACS analysis that vedolizumab binds specifically to cells exogenously expressing the α4 and β7 intergrin proteins [25]. | View biological activity

Bioactivity Comments: PF-06651600 exhibits favourable selectivity against a screening panel of 305 kinases in vitro, and shows measurable inhibition of 7 of the 10 other kinases which share a cysteine residue analogous to Cys-909 in the JAK3 ATP binding site (these were BMX, ITK, TXK, TEC, BTK, BLK and HER4) [28].
ATP concentration for JAK3 is 4 μM at Km and for JAK1 is 40 μM at Km, but some assays reported in [28] were carried out at 1 mM ATP . | View biological activity
PF-00547659 31
Immuno Disease Comments: Phase 2 clinical candidate for UC (see NCT01771809).
Clinical Use: PF-00547659 has completed Phase 2 clinical trials for ulcerative colitis and Crohn's disease. Results from Phase 2 ulcerative colitis trial NCT01620255 were published by Vermeire et al. (2017) [31] | View clinical data
Bioactivity Comments: PF-00547659 binding exhbits >30-fold difference in target affinity between in vitro SPR (surface plasmon resonance) derived KD and clinically derived KD, thought to be due to conformational restrictions in membrane-bound MAdCAM-1 compared to soluble MAdCAM-1 [32]. | View biological activity
Immuno Disease Comments: Approved by the FDA for the treatment of UC.
Clinical Use: Tofacitinib was intiailly approved for the treatment of rheumatoid arthritis. Marketed formulations contain tofacitinib citrate (PubChem CID 10174505).
In Feb 2016 Xelanj XR® was FDA approved as the first once-daily oral JAK inhibitor for rheumatoid arthritis.
In June 2018, FDA approval was expanded to include treatment of patients with moderate to severe ulcerative colitis (UC), subsequent to results from the Phase 3 OCTAVE studies, in which treatment of UC patients with tofacitinib met all primary endpoints and induced significant disase remission [15,19,24]. Xelanj XR® is not approved for UC.

A report in JCI Insight in September 2016 suggests that tofacitinib-induced immunosuppression can stimulate significant hair regrowth in patients with the autoimmune condition alopecia areata [5], although more extensive studies would need to be conducted before the drug could be approved for this indication.

Bioactivity Comments: Like many first generation kinase inhibitors tofacitinib exhibits a high degree of broad kinome selectivity but is in reality a pan-JAK-inhibitor. Additional kinases inhibited by tofacitinib in biochemical and cellular assays are described in [17]. Tofacitinib is also reported to exhibit immunosuppressive activity which prevents organ rejection in mice and primates [4].
Despite clinical efficacy in ulcerative colitis, tofacitinib did not show significant efficacy as an induction and maintenance therapy over placebo, in Crohn's disease patients (as evaluated in Phase 2 studies NCT01393626 and NCT01393899) [18]. | View biological activity
