Description
[0001] Disclosed herein are thienopyrrolotriazine compounds, their preparation, their pharmaceutical composition comprising said compounds, and their therapeutic use.
[0002] The compounds according to the present disclosure are useful as inhibitors of NOD-like receptor protein 3 (NLRP3) inflammasome pathway.The NOD-like receptor protein 3:
[0003] The NOD-like receptor (NLR) family, pyrin domain-containing protein 3 (NLRP3) or NACHT, LRR and PYD domains-containing protein 3 (NALP3), is a cytosolic sensor of diverse pathogen- and host-derived molecules. Upon activation, NLRP3 oligomerizes and recruits an adaptor protein called apoptosis-associated speck like protein (ASC). ASC then polymerizes to form a large aggregate known as ASC speck. In turn, polymerized ASC interacts with the cysteine protease caspase-1 to form a complex termed the inflammasome. This multicomplex protein forms a platform for the binding, dimerization, and activation of the caspase-1 protease. Caspase-1 then cleaves the precursor forms of the pro-inflammatory cytokines IL1β and IL18 (termed pro- IL1β and pro-IL18) and thereby activates adapted inflammatory responses. However, this pathway was shown to be associated with various inflammation associated processes and diseases, including: Neurodegenerative diseases such as Parkinson's Disease (PD), Multiple System Atrophy (MSA), Alzheimer's Disease (AD), Frontotemporal Dementia (FTD), Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS) and Brain injury (Guan Y & Han F.

Cell. Physiol. 221: 262-272, 2009), acute glaucoma (Chi W. et al. National Academy Science 111: 11181-11186, 2014), age-related macular degeneration (Tseng W.A. et al., Investigative Ophthal & Visual Science 54: 11-120, 2013), Behcet's syndrome and dry eye disease (Zheng Q. et al., Experimental Eye Research 134: 133-140, 2015); Metabolic, cardiac, skin disorder & cancer, e.g., diabetic cardiomyopathy (Luo B. et al., PLoS ONE 9(8): e104771, 2014); Kawasaki disease (Jia et al. Cell Death and Disease 10:778; 2019; Anzai F. et al., J. Molecular & Cell Cardiology 138: 185-196, 2020); cardiovascular metabolic disorders, atherosclerosis, type I and type II diabetes and related complications, peripheral artery disease (PAD), acute heart failure and hypertension (Ridker et al., N. Engl. J. Med. 2017, 377, 1119-31; wound healing and scar formation; inflammatory skin diseases (Sweeney et al., Br. J. Dermatol. 2015, 173, 1361), asthma, sarcoidosis, age-related macular degeneration; cancer related diseases, e.g., myeloproliferative neoplasms, leukemias, myelodysplastic syndromes (MDS), myelofibrosis, lung cancer, colon cancer (Ridker et al., Lancet 2017, 390, 1833-42); and SARS-Cov-2: NLRP3 inflammasome is key player in antiviral responses (Zhao C. and Zhao W. 11, 211: 2020; Freeman & Swartz, Frontiers in Immunol. 11, 1518, 2020).

[0021] In accordance with the present disclosure the compounds of general formula (I) can be prepared by the following process.
[0022] Unless otherwise mentioned, R is an alkyl group, X is a halogen atom and R 1 to R 3 are as defined previously.
[0023] Compounds of general formula (I) can be prepared by the Reaction scheme 1 where a bicyclic thienopyrrolecarboxylic ester (GS 1) is transformed with hydrazine to provide the carboxy hydrazide analogue (GS 2). (GS 2) is then reacted with a hydrochloride salt of an imidate where R 2 is alkyl, cycloalkyl, alkoxyalkyl or hydroxyalkyl, following by addition of a base such as tBuOK to obtain after cyclization triazinone (GS 3). (GS 3) is then alkylated with alkyl haloacetate using a base like K 2 CO 3 to give ester (GS 4), which is then saponified using an aqueous base to give acid (GS 5), followed by a coupling with an appropriate amine H 2 N-R 3 using known standard methods like EDC / HOBT Et 3 N, HATU DIPEA to provide a compound of general formula (I).
[0024] Compounds of the present disclosure with R 1 =Br may be prepared by the reaction scheme 2 where the ester intermediate in which R 1 =H (GS 4, R 1 =H) is reacted with a brominated agent like NBS to obtain the corresponding brominated derivative (GS 6), which is then saponified using an aqueous base to obtain the carboxylic acid (GS 7), followed by a coupling with an appropriate amine H 2 N-R 3 using known standard methods like EDC / HOBT Et 3 N, HATU DIPEA to provide a compound of general formula (I').
[0025] A modified reaction sequence of scheme 1 is applied for R 2 = C(OH)(CH 3 ) 2 . Compounds of general formula (I), where R 2 is 2-hydroxypropan-2-yl, can be prepared by the reaction scheme 4 where general structure (GS 3 with R 2 = CH(OH)-CH 3 ) is oxidized with standard methods like Swern oxidation or Dess-Martin oxidation to provide a ketone (GS 8) which is engaged in a Grignard reaction using for example MeMgCl to obtain (GS 9). This intermediate is then alkylated with alkyl haloacetate using a base like K 2 CO 3 to give ester (GS 10), which is then saponified to the corresponding carboxylic acid (GS 11), followed by a coupling with an appropriate amine H 2 N-R 3 using known standard methods like EDC / HOBT Et 3 N, HATU DIPEA to provide a compound of general formula (I").

[0259] Monocytic THP-1 cells (DSMZ) were maintained in RPMI media (RPMI 1640 Medium (1×) +10% FBS, Eurobio CVFSVFOO-OU). Cells were then plated at 16,000 cells per well in 96-well round bottom cell culture plates (TPP, ref 92097) and maintained with RPMI and 0.1% Bovine Serum Albumin solution. Activation of the NLRP3 inflammasome requires both an NF-kB-dependent priming step and the addition of a NLRP3 activator. The priming step was induced by LPS (10ng / mL, Sigma, ref:L4391) for 3h at 37°C, then compound, in a 1:3.10 serial dilution series in DMSO 1:100, and the activator nigericin (Sigma Aldrich, ref : SML1779) 10µM (final concentration) were added to the cells and co-incubated for 2 h. 50 µL supernatant was removed, and IL-1β levels were monitored using an MSD assay (Electro Chemical Luminescence Immunoassay (ECLI) according to manufacturers' instructions.TNF-α secretion assay
[0260] Monocytic THP-1 cells (DSMZ) were maintained in RPMI media (RPMI 1640 Medium (1×) +10% FBS, biowest S181 H).

[0261] IC 50 values were calculated from the plot of percentage of inhibition versus the inhibitor concentration by a logistics fit according to: y = A2 + (A1 - A2) / (1 + (x / IC 50 )^p) where y is the %-inhibition at the inhibitor concentration, x. A1 is the lowest inhibition value, i.e., 0 %, and A2 the maximum inhibition value, i.e., 100 %. The exponent, p, is the Hill coefficient. The curve fitting was conducted with an internally developed software.Brain over plasma ratio evaluation
