Description
NOVEL SUBSTITUTED SULFONYLUREA DERIVATIVES
FIELD OF THE INVENTION
The présent invention relates to novel heterocyclic compounds of the general formula (I) their pharmaceutically acceptable salts, pharmaceutically acceptable solvatés, enantiomers, diastereomers and polymorphs. The invention also relates to processes for the préparation of the compounds of invention, pharmaceutical compositions containing the compounds and their use as the compounds of the invention belong to the family of NOD-like receptor family (NLR) protein NLRP3 modulators. The présent invention thus relates to novel NLRP3 modulators as well as to the use of the novel inhibitor compounds in the treatment of diseases or conditions in which interleukin 1 β activity is implicated.
BACKGROUND OF THE INVENTION
The NOD-like receptor family (NLR) protein NLRP3 is an intracellular signaling molécule that senses many pathogens, environmental and host-derived factors. (Wen., et. al., Immunity. 2013; 39:432-441). Activation of NLRP3 leads to binding with apoptosis associated speck-like protein containing a CARD (ASC). ASC in turn interacts with the cysteine protease caspase-1, forming a complex termed the inflammasome. This results in the activation of caspase-1, which cleaves the pro-inflammatory cytokines IL-Ιβ and IL-18 to their active forms and médiates a type of inflammatory cell death known as pyroptosis. Other intracellular pattern récognition receptors (PRRs) are also capable of forming inflammasomes. These include other NLR family members such as NLRP1 and NLRC4 and non-NLR PRRs such as the double-stranded DNA (dsDNA) sensors absent in melanoma 2 (AIM2) and interferon, gamma inducible protein 16 (IFI16) (Latz, et. al., Nat Rev Immunol. 2013; 13:397U11). NLRP3-dépendent IL-Ιβ processing can also be activated by an indirect, non-canonical pathway downstream of caspase-1 (Lamkanfi, et. al., Cell. 2014; 157:1013-1022).
g Inflammasome components such as NLRP3, ASC and caspase-1 are expressed in immune cells in the liver including Kupffer cells, infiltrating macrophages, hépatocytes, and hepatic stellate cells.
| 30 Inflammasome activation is dépendent on two successive signais. Signal 1 is driven by TLR and IL-1R signaling, includes expression of component proteins including NLRP3, ASC, pro-caspase] 1, pro-IL-1 β, and pro-IL-18. Signal 2 is provided by danger signais (DAMPS) that during NASH development are mainly released by stressed or dying hépatocytes or via a ”leaky” gut (PAMPs).

The NLRP3 inflammasome acts as a key mediator of inflammatory responses through the activation of caspase-1 leading to processing and release of the pro-inflammatory cytokines interleukin-ΐβ (IL-1 β) and interleukin-18 (IL-18). The NLRP3 inflammasome is a component of 5 the inflammatory process and its aberrant activation is pathogenic in inherited disorders such as the rare periodic fever syndrome, cryopyrin associated periodic syndromes (CAPS), Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) and complex diseases such as multiple sclerosis, Inflammatory bowel disease (IBD), type 2 diabètes, atherosclerosis, asthma, gouty arthritis, and inflammatory central nervous system (CNS) diseases including Parkinson's, 10 Alzheimer’s and other brain diseases.

Inflammation is an essential host response to infection and injury. The régulation of the proinflammatory cytokine interleukin-ΐβ (IL-Ιβ), which is central to host responses to infection, also causes tissue injury when activated inappropriately. (Dinarello, et. al., Nat. Rev. Drug Discovery 2012, 11, 633-652.) NLRP3 inflammasome activation plays a key rôle in each ofthe components including induction of pro-inflammatory signaling, hepatocellular injury and cell death, and activation ofthe hepatic stellate cells (HSC) that are responsible for collagen déposition and liver fibrosis. In particular, the transition from NAFLD to NASH associâtes with NLRP3inflammasome activation and an increased expression of inflammasome-related components, including apoptosis-associated speck-like protein containing a carboxy-terminal CARD (ASC), caspase-1 (CASP-1) and pannexin. (Mridha, et. al., Journal of Hepatology, 2017, 66 (5), 10371046)
Current treatments for NLRP3 related diseases include biologie agents that target IL-1. These are the recombinant IL-1 receptor antagonist Anakinra, the neutralizing IL-1 β antibody Canakinumab and the soluble decoy IL-1 receptor Rilonacept.

Biological Activity:
In-vitro assay:
— THP1 monocytes were differentiated with PMA (lOOng/mL) and incubated at 37 degC for 20hrs in presence of 5% CO2. 2X105 differentiated cells were plated per well of 96 well tissue culture
I plates. The cells were primed using 500 ng/mL Lipopolysaccharide and incubating for 4h under
0 the same condition. The cells were then treated with various concentrations of the compounds for 130 min followed by treatment with 5 mM ATP for Ihr. The supematants were collected and analyzed by IL-lb (Mabtech Cat # 3415-1H-20) or TNF-a (Mabtech; Cat # 3510-1H-20) détection kit. The data were analyzed using GraphPad Prism V7.0. Dose Response Curve (DRC) was constructed to détermine the IC50 value by fitting percentage cell survival data to the GraphPad
Prism using nonlinear régression analysis. The invitro IL-Ιβ inhibitory activity (IC50) for représentative compounds are listed in Table 1.

Animais
Ail the animal experiments were carried out in female rats and mice, bred in-house. Animais were 5 housed in groups of 6 animais per cage, for a week, in order to habituate them to vivarium conditions (25 ± 4 °C, 60-65 % relative humidity, 12: 12 h light: dark cycle, with lights on at 7.30 am). Ail the animal experiments were carried out according to the intemationally valid guidelines following approval by the 'Zydus Research Center animal ethical committee'.
In-vivo LPS and ATP induced IL-Ιβ assay:
Female C57 mice (6-8 weeks) received intraperitoneal injection of 50 qg/mouse of lipopolysaccharide (LPS) in PBS. Animais were treated immediately with the test compounds or the vehicle. After 2h of LPS injection, animais were administered with ATP at 12.5 mg/mouse dissolved in PBS via intraperitoneal route. After 30 minutes of ATP injection, sérum was collected for IL-Ιβ estimation by ELISA.
