Description

[0001]TREATMENT FOR INFLAMMATORY BOWEL DISEASE FIELD OF THE INVENTION The present invention relates to the development of therapeutic compound for the treatment of inflammatory bowel disease (IBD). Specifically, the present invention provides a NLRP3 inhibitors or its pharmaceutically acceptable salt or suitable composition useful in the treatment of inflammatory bowel diseases. These severe and persistent illnesses include Crohn's disease and ulcerative colitis, lymphocytic colitis, microscopic colitis, collagenous colitis, autoimmune enteropathy, allergic gastrointestinal disease, eosinophilic gastrointestinal disease and other related forms of disorders. BACKGROUND OF THE INVENTION The nucleotide-binding oligomerization domain (NOD)-like receptor family, pyrin domain-containing 3 (NLRP3 or NALP3) inflammasome are a major source of mucosal interleukin (IL)-1β and the inflammasomes are mostly subject to activation by multiple aspects of inflammation-associated stress. NLRP3 is a cytosolic pattern recognition receptor (PRR) that senses exogenous and endogenous danger signals. The NLRP3 protein is made up of three domains: a leucine-rich repeat domain (LRR), a NOD containing a caspase activation and recruitment domain (CARD) (NACHT), and a pyrin domain (PYD). Upon activation, NLRP3 oligomerizes and triggers assembly of the adapter apoptosis-associated speck-like protein containing a CARD (ASC) via PYD–PYD interactions. ASC fibrils assemble into large structures, called ASC specks, and recruit pro-caspase-1, leading to its autoproteolytic activation. The activated caspase-1 is able to cleave pro-IL-1β and pro-IL-18 to generate the inflammatory cytokines IL-1β and IL-18 (Guo et al., 2015; Dinarello et al., 2012). Involvement of the NLRP3 inflammasome in different kinds of diseases provides new avenues to design drugs targeting NLRP3 inflammasome. To date, clinical treatment of NLRP3-related diseases targets IL-1β with IL-1β antibodies or recombinant IL-1β receptor antagonist, such as canakinumab and anakinra, respectively. In addition, a few small-molecule compounds have shown anti-inflammatory effects on NLRP3 inflammasome activation in vitro, including MCC950, β-hydroxybutyrate (BHB), Bay 11-7082, dimethyl sulfoxide (DMSO), and type I interferon. However, most of these inhibitors are relatively nonspecific and have low efficacy. For inhibitors targeting IL-1β, it should be noted that IL-1β secretion is not the only product of NLRP3 inflammasome activation; instead, other proinflammatory cytokines, including high-mobility group box 1 (HMGB1) and IL-18 may participate in the pathogenesis of these diseases. Moreover, IL- 1β can be produced by inflammasome-independent pathways or other inflammasomes. Therefore, inhibitors targeting IL-1β may lead to unintended immunosuppressive effects besides preventing NLRP3 inflammasome activation itself. Pharmacological inhibitors specific to NLRP3 inflammasome may be the best choice for treatment of NLRP3-related diseases (Yang et al., 2019). IBD is a chronic gastrointestinal inflammatory disease that affects the entire gastrointestinal tract and the colon. Two of the most common types of IBD include ulcerative colitis (UC) and Crohn’s disease (CD). Approximately more than 5 million people in the industrialized world suffer from IBD. In Europe, the incidence of UC and CD was 0.5% and 1%, respectively. The number of IBD patients increases dramatically worldwide, especially in China and other Asian countries. Major symptoms of IBD include abdominal pain, abdominal distension, diarrhea, and mucous pus blood, which have a significant impact on the quality of life of these patients. Current treatment for IBD mainly includes steroids and immune suppressive agents, especially antibodies to inflammatory cytokines. These biological agents exert their function by neutralizing inflammatory cytokines. For example, Infliximab (IFLX), the first anti-tumor necrosis factor (TNF)-α monoclonal antibody approved by the US Food and Drug Administration (FDA), eliminates the biological activity of cytosolic and membrane-bound pro- inflammatory cytokine TNF-α. Subsequently, IFLX induces apoptotic cell death of pro- inflammatory cells. IFLX increases clinical remission in CD and UC patients, and heals fistulas in CD. However, the long-term use of IFLX and other biological agents leads to relapse, generation of anti-drug antibodies, or malignancy. Anti-interleukin (IL)- 12 / IL-23 therapy, small molecule inhibitors to sphingosine-1-phosphate, Janus kinase, purinergic receptor P2X, ligand-gated ion channel 7 receptor, and Bruton tyrosine kinase (BTK), are currently in the IBD pipeline. However, detailed pathogenic factors that trigger IBD are tremendously complicated and remain largely unresolved. The combination of drugs with different activities could increase clinical efficacy and / or safety profile. Therefore, novel therapy with distinct mechanisms of action is of urgent need for the long-term treatment of IBD patients in remission and / or to improve quality of life of the affected patients. (Biomedicine & Pharmacotherapy, June 2021, 111442). Activation of NLRP3 is considered as an important inducing factor that triggers pathogenesis of IBD, such as sterile inflammation activation in intestinal epithelial cells and sustained activation of macrophages.

While the present invention has been described in terms of its specific embodiments, certain modifications and equivalents will be apparent to those skilled in the art and are intended to be included within the scope of the present invention. Biological Activity: In-vitro assays: THP1 monocytes were differentiated with PMA (100ng / ml) and incubated at 37 °C for 20 hrs in presence of 5% CO2. 2X105 differentiated cells were plated per well of 96 well tissue culture plates. The cells were primed using 500ng / mL Lipopolysaccharide and incubating for 4h under the same condition. The cells were then treated with various concentrations of the compounds for 30 min followed by treatment with 5mM ATP for 1hr. The supernatants were collected and analyzed by IL-1β (Mabtech Cat # 3415-1H-20) or TNF-a (Mabtech; Cat # 3510-1H-20) detection kit. The data were analyzed using GraphPad Prism V7.0. Dose Response Curve (DRC) was constructed to determine the IC50value by fitting percentage cell survival data to the GraphPad Prism using nonlinear regression analysis. The in vitro IL-1β inhibitory activity (IC50) for representative compounds are listed in Table 1.

Female C57BL / 6 mice were housed in our facility for one week before DSS experiments were run. Colitis was induced by administration of DSS (molecular weight [MW] =36,000–50,000 Da; MP Biomedicals). Three groups of animals were treated twice daily for eight days with various doses (1, 5 and 10 mg / kg, p.o.) of compound of formula (11). Control group animals received vehicle only. Mice were treated with 2% DSS dissolved in drinking water for 5 days, followed by regular access to water till the end of study. Weight loss and mortality were monitored daily until study termination. A scoring system was applied to assess diarrhea and the presence of occult or overt blood in the stool in the last day of the study. Changes in body weight were indicated as loss of baseline body weight as a percentage. Disease activity index (DAI) was determined based on a scoring system. The scoring criteria included that for (a) body weight where 0 corresponded to no loss of weight and 4 corresponding to >20% weight loss; (b) Stool consistency where 0 is normal and 3 is diarrhea; rectal bleeding where 0 is no abnormalities and 4 is severe. Results Dextran sodium sulphate (DSS) (diseased control) caused an increase in DAI score associated with shrinkage of colon length as compared to normal control group. Treatment with compound of formula (11) was found to lower disease activity index (DAI) associated with an improvement in colon length. Groups Disease % Colon % activity index inhibition length improvement The compounds of formula (I) or pharmaceutical compositions containing them are useful as a medicament for the inhibition of NLRP3 activity and suitable for humans and other warm-blooded animals, and may be administered either by oral, topical or parenteral administration. Evaluation of effect of compound of Formula (11) in 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced IBD model in rat TNBS-IBD is a chemical-induced IBD model with an overall etiology, including some immunological and histological changes in the GI tract that resembles human disease. We aimed to evaluate the effect of Formula (11) in TNBS-induced IBD model in rat. Male Sprague Dawley rats randomized into various treatment groups were subjected to colitis induction by rectal administration of TNBS in 50% ethanol. Different groups of animals were treated twice daily for six days with various doses (1, 5, 25 and 50 mg / kg, p.o.) of Formula (11). Control group animals received vehicle only. On 7th day, body weight was recorded, animals were sacrificed and colon was removed, washed and length & weight were recorded. Results Treatment with compound of formula (11) showed dose-related improvement in body weight loss (Figure-1) and shortening of colon length due to TNBS challenge (as shown in the following table).
