Title: Novel compounds for inhibition of janus kinase 1

Description:
FIELD OF THE INVENTION 
     The invention relates to inhibitors of Janus Kinase 1 (JAK1), a process for synthesis of the compounds of the present invention, composition comprising the compounds and use of the compounds for inhibition of JAK1. 
     BACKGROUND OF THE INVENTION 
     Cytokines are key drivers of several biological pathways and anti-cytokine therapy is indicated if there is any dysregulation in the pathway. Signalling pathways for Type I and Type II cytokine receptors, a family of receptors employed by over 50 cytokines, interleukins, interferons, colony stimulating factors, and hormones. Like other receptor super families, Type I and Type II cytokine receptors are related by their mode of intracellular signaling: they all employ JAKs. Janus Kinases (JAK) are intracellular tyrosine kinases linked to intracellular domains of many cytokine receptors. There are four JAK isoforms: JAK1, JAK2, JAK3 and TYK2. JAK1, JAK2, JAK3 and Tyrosine Kinase 2 (TYK2) bind directly to the intracellular domains of Type I/11 cytokine receptors and not to other classes of cytokine receptors. Different cytokine receptor families utilize specific JAK isoforms for signal transduction. Phosphorylation of JAK when cytokine binds to its cognate receptor leads to phosphorylation of other intracellular molecules that eventually leads to gene transcription. JAK-dependent cytokines are major contributors to immunopathology and that blocking such cytokines with biologics can be beneficial in immune-mediated diseases and in cancers and several other major disease and disorders. 
     Several inhibitors of JAK kinase exist. They block multiple JAKs and therefore inhibit the actions of a large variety of cytokines and several pan-JAK inhibitors continue to be developed. The JAK isoforms vary in function, and therefore there exists a need in the art for isoform-specific inhibitors that can reduce undesired effects from the administration of generalized JAK inhibitors. JAK1 plays a key role in types I and II interferon signaling and elicits signals from the interleukin-2, interleukin-4, gp130 and class II receptor families. As such, small molecule inhibition of JAK1 may intervene in the signaling pathways involved in oncology, inflammation and autoimmune diseases. However, to minimize adverse effects, especially those arising from JAK2 inhibition, the generation of selective inhibitors could in principle maintain efficacy and improve safety. 
     OBJECT OF THE INVENTION 
     An object of the invention is to provide compounds as selective JAK1 inhibitor, a process for preparation of the inhibitors, a composition containing the compounds and utility of the compounds. 
     SUMMARY OF THE INVENTION 
     The present invention discloses 1H-imidazo[4,5-b]pyridin-2(3H)-one as selective inhibitor of JAK 1 their pharmaceutically acceptable salts and isomers of formula I.

     The compounds of the present invention were tested for their activity and were found to be active. The assays and results are presented here below. 
     Biological Example 1: JAK Biochemical Assay 
     Recombinant JAK1, JAK2, JAK3 and TYK2 (Carna Biosciences) were used to develop biochemical assays in 50 mM HEPES pH 7.5, 1 mM EGTA, 10 mM MgCl 2 , 2 mM DTT and 0.01% Tween-20. Amount of enzyme, substrate (ULigh-JAK-1 (Tyr1023) Peptide and ATP concentrations to be used was determined for each kinase assay by respective titration and Km studies. Biochemical assay was developed by LANCE Ultra TR-FRET technology (Perkin Elmer). Enzyme and compounds were incubated at 22° C. for 60 minutes in a white 384 well optiplate (Perkin Elmer). Substrate and ATP were added to the above mix and incubated further for 90 minutes. Reaction is terminated by adding EDTA and detection antibody (Europium-anti-phospho-tyrosine (PT66) Antibody) was added. Assay read out was measured in TR-FRET mode in BMG FLUOstar multimode reader. Upon irradiation at 320 nm, the energy from the Eu donor is transferred to the ULight acceptor dye which, in turn, generates light at 665 nm. The intensity of the light emission is proportional to the level of ULight substrate phosphorylation. Compounds which interfere with JAK enzyme activity show a lesser substrate phosphorylation and values are projected in terms of % inhibition in comparison to vehicle control.

     Data thus generated for compounds were compared with two reference standards, filgotinib—a JAK1 selective inhibitor, and tofacitinib—pan JAK inhibitor. Example 1133, 1181 and 1215 showed better potency as well as selectivity for JAK1 (7 to 80 fold selective for JAK1 vs JAK2; 3 to 22 fold selective for JAK1 vs JAK3) compared to filgotinib (0.9 fold JAK1 vs JAK2; 12 fold JAK1 vs JAK3). These compounds are also far superior in terms of JAK1 selectivity compared to a pan inhibitor such as tofacitinib. 
     Biological Example 6: Mouse Model of Rheumatoid Arthritis 
     Rheumatoid arthritis (RA) is an autoimmune disease that can cause joint pain and damage throughout the body. Several cytokines such as IL-6 and IFN-γ activate the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway. Inhibition of JAK/STAT pathway is considered as one of the therapeutic options for treatment of rheumatoid arthritis. Rodent models of arthritis can be used to evaluate the therapeutic potential of compounds dosed preventatively or therapeutically. These models include but are not limited to mouse or rat collagen-induced arthritis, rat adjuvant-induced arthritis, and collagen antibody-induced arthritis. 
     Compounds described herein are tested for JAK/STAT pathway inhibition driven efficacy in collagen induced mouse arthritis model. Compounds were orally dosed, QD for 21 days and at the end of the study, clinical symptoms, body weight and histopathology of ankle and paws were measured. Arthritis score was calculated for the compounds as well as reference standard, filgotinib. By way of exemplification, examples 1215, 1181 and 1133 showed very good efficacy and are better or comparable to filgotinib. 
     Biological Example 7: Mouse Model of Imiquimod Induced Psoriasis 
     Imiquimod (IMQ) induced dermatitis closely resembles human psoriasis lesions not only with regard to phenotypic and histological characteristics but also in the development of the lesions. IMQ is a ligand for toll-like receptor 7 (TLR7) and TLR8, and is a potent immune activator. IMQ&#39;s immunomodulatory effects in triggering psoriasis are attributed to stimulation of TLR7 and TLR8 on plasmacytoid dendritic cells (pDCs) and an upregulated type I interferon pathway. Migration of activated dermal dendritic cells to lymph nodes in skin triggers a sequence of events leading to late phase of psoriasis. Compounds described herein are tested for JAK inhibition driven efficacy in Imiquimod induced dermatitis in mice. 
     Female BALB/c mice were topically dosed with 3% cream formulation containing test compounds. After four hours of test compound administration, 5% Imiquimod was applied on back skin and right ear for five days. On day 6, post dosing with test compounds, the severity of psoriasis was monitored and graded following Psoriasis Area and Severity Index (PASI). Efficacies of the compounds were evaluated based on PASI score. Redness, thickness and scaling of back skin and ear were assessed among the groups for scoring. 
     Compounds of the present invention for instance, Example 1133, Example 1215 and filgotinib showed statistically significant decrease in cumulative psoriasis score compared to vehicle. There was a significant decrease in back skin thickness, ear thickness on administration of Example 1133, 1215 and filgotinib (3% topical, QD). Example 1215 showed better efficacy compared to 1133 and reference compound filgotinib. The data is represented by way of a  FIG. 1 . From the FIGURE, it can be clearly seen that there the exemplary compounds of the present invention show enhanced efficacy when compared to the compounds available in the market such Filgotinib. 
     Biological Example 9: Murine Model of Oxazolone Induced Colitis 
     The animal in which the colitis is produced can be any mammal and can include but is not limited to mouse, rat, guinea pig, hamster, rabbit, cat, dog, goat, monkey, and chimpanzee. The colitis can be produced in the animal by any method known in the art. A mouse model of oxazolone induced colitis was utilized to study the efficacy of JAK inhibitors. Oxazolone colitis has a histological resemblance to human ulcerative colitis. Pro-inflammatory cytokines elevated in ulcerative colitis rely on JAK family of tyrosine kinases for signal transduction. It has been proposed that JAK inhibition may be beneficial in the treatment of ulcerative colitis. 
     Male BALB/c mice were used in the study, 10-12 weeks, on day 1, 4% Oxazolone (in 4:1 acetone:olive oil formulation) or vehicle solution was applied between shoulders to anesthetized animals. Seven days after skin sensitization, mice were fasted for 6 hours prior to intra-rectal administration of 1% oxazolone (in 1:1 ethanol:water formulation). Drug treatment or vehicle administration (PO, BID) was initiated on day 6, a day prior to intra-rectal oxazolone challenge. Animals were dosed with test compounds or vehicle till day 9. Disease activity index (DAI) was graded for each mouse by treatment-blinded experimenters. Body weight loss (0=none, 2=&gt;5-10%, 4=&gt;20%), stool consistency (0=normal, 2=soft without pellet, 4=severe diarrhoea) and rectal bleeding (0=no blood, 2=bloody stool, 4=adhesion of blood to anus&amp; part of tail) were assessed for DAI score. 
     Below Table 4, mentions the scores of the compounds with respect to disease activity index parameters in comparison with vehicle treated group.
