Definitions

  • the present invention relates to novel heterocyclic compounds of the general formula (I) their pharmaceutically acceptable salts, pharmaceutically acceptable solvates, enantiomers, diastereomers and polymorphs.
  • the invention also relates to processes for the preparation 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.
  • NLR NOD- like receptor family
  • the present 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 as well as treatment of disease states mediated by NLRP3 as well as treatment of diseases or conditions in which interleukin 1 ⁇ activity and interleukin-18 (IL-18) is implicated.
  • NLR protein NLRP3 is an intracellular signaling molecule 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-1 ⁇ and IL-18 to their active forms and mediates a type of inflammatory cell death known as pyroptosis. (Latz, et. al., Nat Rev Immunol.2013; 13:397–411).
  • 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-1 ⁇ (IL-1 ⁇ ) and interleukin-18 (IL-18).
  • the NLRP3 inflammasome is a component of 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, type 2 diabetes, atherosclerosis, asthma, gouty arthritis, Juvenile arthritis, and inflammatory central nervous system (CNS) diseases.

  • HSC hepatic stellate cells
  • NLRP3 related diseases include biologic agents that target IL-1. These are the recombinant IL-1 receptor antagonist Anakinra, the neutralizing IL-1 ⁇ antibody Canakinumab and the soluble decoy IL-1 receptor Rilonacept.

Description

NOVEL SUBSTITUTED SULFONYLUREA DERIVATIVES FIELD OF THE INVENTION
The present invention relates to novel heterocyclic compounds of the general formula (I) their pharmaceutically acceptable salts, pharmaceutically acceptable solvates, enantiomers, diastereomers and polymorphs. The invention also relates to processes for the preparation 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 present 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 as well as treatment of disease states mediated by NLRP3 as well as treatment of diseases or conditions in which interleukin 1β activity and interleukin-18 (IL-18) is implicated.
BACKGROUND OF THE INVENTION
The NOD-like receptor family (NLR) protein NLRP3 is an intracellular signaling molecule 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-1β and IL-18 to their active forms and mediates a type of inflammatory cell death known as pyroptosis. (Latz, et. al., Nat Rev Immunol.2013; 13:397–411).
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-1β (IL-1β) and interleukin-18 (IL-18). The NLRP3 inflammasome is a component of 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, type 2 diabetes, atherosclerosis, asthma, gouty arthritis, Juvenile arthritis, and inflammatory central nervous system (CNS) diseases. (Masters, et. al., Annu Rev Immunol. 2009; 27:621–668; Strowig, et. al., Nature 2012, 481, 278−286; Guo, et. al., Nat. Med.2015, 21, 677.) Inflammation is an essential host response to infection and injury. The regulation of the pro-inflammatory cytokine interleukin-1β (IL-1β), 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 role in each of the components including induction of pro-inflammatory signaling, hepatocellular injury and cell death, and activation of the hepatic stellate cells (HSC) that are responsible for collagen deposition and liver fibrosis. (Mridha, et. al., Journal of Hepatology, 2017, 66 (5), 1037-1046)
Current treatments for NLRP3 related diseases include biologic agents that target IL-1. These are the recombinant IL-1 receptor antagonist Anakinra, the neutralizing IL-1β antibody Canakinumab and the soluble decoy IL-1 receptor Rilonacept.
Published patent applications WO98/32733, WO2001/019390, WO2014/190015, WO2016/123229 discloses certain compounds which are modulators of NLRP3. WO/2016/131098 filed by The University of Queensland disclosed sulfonylureas derivatives and related compounds as NLRP3 inflammasome inhibitors. WO2017/017469 filed by The University of Manchester, disclosed certain cyclic diarylboron derivatives as NLRP3 inflammasome inhibitors for the treatment of diseases or conditions in which interleukin 1 β activity is implicated. Some of the recent patent applications such as WO2017031161, WO2017079352, WO2017129897, WO2017184604, WO2017184623, WO2017184624 and WO2018015445 also disclose certain classes of compounds as NLRP3 inhibitors.
We herein disclose novel heterocyclic compounds of general formula (I) which are NLRP3 modulators for the prevention and treatment of disease states mediated by NLRP3 or conditions in which interleukin 1β activity and interleukin-18 (IL-18) are implicated including inflammation, gouty arthritis, type 2 diabetes, atherosclerosis, and liver fibrosis. More particularly, embodiments of the present invention are useful as therapeutics in the treatment of a variety of pathological conditions including (but not limited to) lymphoma, auto-immune diseases, heteroimmune diseases, inflammatory diseases, type 1 diabetes, chronic inflammation, cancer, and neurodegenerative diseases or conditions. SUMMARY OF THE INVENTION The present invention discloses heterocyclic compounds as defined by the general formula (I) that are NLRP3 modulators for the prevention and treatment of disease states mediated by NLRP3 as well as treatment of diseases or conditions in which interleukin 1β activity and interleukin-18 (IL-18) are implicated.

The cells were primed using 500ng/ml Lipopolysaccharide and incubating for 4hrs 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 analysed by IL-1b (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 IC50 value by fitting percentage cell survival data to the GraphPad Prism using nonlinear regression analysis. The invitro IL-1β inhibitory activity (IC50) for representative compounds are listed in Table 1. Table 1

In vivo efficacy studies: Demonstration of in vivo efficacy of test compounds in rats mice, oral routes of administration. Animals All the animal experiments were carried out in female rats and mice, bred in-house. Animals were housed in groups of 6 animals 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). All the animal experiments were carried out according to the internationally valid guidelines following approval by the 'Zydus Research Center animal ethical committee'. In-vivo LPS and ATP induced IL-1β assay: Female C57 mice (6-8 weeks) received intraperitoneal injection of 50 µg/mouse of lipopolysaccharide (LPS) in PBS. Animals were treated immediately with the test compounds or the vehicle. After 2h of LPS injection, animals were administered with ATP at 12.5 mg/mouse dissolved in PBS via intraperitoneal route. After 30 minutes of ATP injection, serum was collected for IL-1β estimation by ELISA. Representative data of some of the test compounds are listed in Table-2. Table 2
