EXAMPLES—BIOLOGICAL STUDIES

[2590] NLRP and Pyroptosis

[2591] It is well established that the activation of NLRP3 leads to cell pyroptosis and this feature plays an important part in the manifestation of clinical disease (Yan-gang Liu et al., Cell Death &Disease, 2017, 8(2), e2579; Alexander Wree et al., Hepatology, 2014, 59(3), 898-910; Alex Baldwin et al., Journal of Medicinal Chemistry, 2016, 59(5), 1691-171; Ema Ozaki et al., Journal of Inflammation Research, 2015, 8, 15-27; Zhen Xie & Gang Zhao, Neuroimmunology Neuroinflammation, 2014, 1(2), 60-65; Mattia Cocco et al., Journal of Medicinal Chemistry, 2014, 57(24), 10366-10382; T. Satoh et al., Cell Death &Disease, 2013, 4, e644). Therefore, it is anticipated that inhibitors of NLRP3 will block pyroptosis, as well as the release of pro-inflammatory cytokines (e.g. IL-13) from the cell.

[2592] THP-1 Cells: Culture and Preparation

[2593] THP-1 cells (ATCC #TIB-202) were grown in RPMI containing L-glutamine (Gibco #11835) supplemented with imM sodium pyruvate (Sigma #S8636) and penicillin (100 units/ml)/streptomycin (0.1 mg/ml) (Sigma #P4333) in 10% Fetal Bovine Serum (FBS) (Sigma #Fo804). The cells were routinely passaged and grown to confluency (˜10.sup.6 cells/ml). On the day of the experiment, THP-1 cells were harvested and resuspended into RPMI medium (without FBS). The cells were then counted and viability (>90%) checked by Trypan blue (Sigma #T8154). Appropriate dilutions were made to give a concentration of 625,000 cells/ml. To this diluted cell solution was added LPS (Sigma #L4524) to give a 1 g/ml Final Assay Concentration (FAC). 40 μl of the final preparation was aliquoted into each well of a 96-well plate. The plate thus prepared was used for compound screening.

[2594] THP-1 Cells Pyroptosis Assay

[2595] The following method step-by-step assay was followed for compound screening. [2596] 1. Seed THP-1 cells (25,000 cells/well) containing 1.0 μg/ml LPS in 40 μl of RPMI medium (without FBS) in 96-well, black walled, clear bottom cell culture plates coated with poly-D-lysine (VWR #734-0317) [2597] 2. Add 5p compound (8 points half-log dilution, with 10 μM top dose) or vehicle (DMSO 0.1% FAC) to the appropriate wells [2598] 3. Incubate for 3 hrs at 37° C. in 5% CO.sub.2 [2599] 4. Add 5 μl nigericin (Sigma #N7143) (FAC 5 μM) to all wells [2600] 5. Incubate for 1 hr at 37° C. and 5% CO.sub.2 [2601] 6. At the end of the incubation period, spin plates at 300 xg for 3 mins and remove supernatant [2602] 7. Then add 50 μl of resazurin (Sigma #R7017) (FAC 100μ M resazurin in RPMI medium without FBS) and incubate plates for a further 1-2 hrs at 37° C. and 5% CO.sub.2 [2603] 8. Plates were read in an Envision reader at Ex 560 nm and Em 590 nm [2604] 9. IC.sub.50 data is fitted to a non-linear regression equation (log inhibitor vs response-variable slope 4-parameters)

[2607] Human Whole Blood IL1β Release Assay

[2608] For systemic delivery, the ability to inhibit NLRP3 when the compounds are present within the bloodstream is of great importance. For this reason, the NLRP3 inhibitory activity of a number of compounds in human whole blood was investigated in accordance with the following protocol.

[2609] Human whole blood in Li-heparin tubes was obtained from healthy donors from a volunteer donor panel. [2610] 1. Plate out 80 μl of whole blood containing 1 μg/ml of LPS in 96-well, clear bottom cell culture plate (Corning #3585) [2611] 2. Add 10 μl compound (8 points half-log dilution with 10 μM top dose) or vehicle (DMSO 0.1% FAC) to the appropriate wells [2612] 3. Incubate for 3 hrs at 37° C., 5% CO.sub.2 [2613] 4. Add 10 μl Nigericin (Sigma #N7143) (10 μM FAC) to all wells [2614] 5. Incubate for 1 hr at 37° C., 5% CO.sub.2 [2615] 6. At the end of the incubation period, spin plates at 300 xg for 5 mins to pellet cells and remove 20 μl of supernatant and add to 96-well v-bottom plates for IL-1β analysis (note: these plates containing the supernatants can be stored at −80° C. to be analysed at a later date) [2616] 7. IL-1β was measured according to the manufacturer protocol (Perkin Elmer-AlphaLisa IL-1 Kit AL220F-5000) [2617] 8. IC.sub.50 data is fitted to a non-linear regression equation (log inhibitor vs response-variable slope 4-parameters)

[2618] The results of the human whole blood assay are summarised in Table 3 below as HWB IC.sub.50.

[2619] PK Protocol

[2620] Pharmacokinetic parameters were determined in male Sprague Dawley rats (Charles River, UK, 250-350 g; or Vital River Laboratory Animal Technology Co Ltd, Beijing, China, 7-9 weeks old). Animals were individually housed during the study and maintained under a 12 h light/dark cycle. Animals had free access to food and water except that some orally dosed animals were food deprived overnight prior to the study.

[2621] For intravenous administration, compounds were formulated as a solution in water or DMSO:PBS [10:90] in 2 mL/kg dosing volume and administered via tail vein. For oral administration, compounds were formulated as a solution in water or DMSO:water [10:90] in 5 mL/kg dosing volume and administered orally.

[2622] Serial blood samples (about 120-300 μL) were taken from each animal at each of 8 time-points post dose (0.083, 0.25, 0.5, 1, 2, 4, 8 and 24 h) or at each of 12 time-points post dose (0.03, 0.1, 0.17, 0.25, 0.5, 1, 2, 4, 6, 8,12 and 24 h) or pre-dose and at each of 9 time-points post dose (0.25, 0.5, 1, 2, 4, 6, 8, 12 and 24 h). Samples were held on ice for no longer than 30 minutes before centrifugation (10,000 rpm (8,385 g) for 3 minutes; or 5,696 rpm (3,000 g) for 15 minutes) for plasma generation. Plasma was frozen on dry ice prior to bioanalysis. PK parameters were generated from LC-MS/MS data using Dotmatics or Phoenix WinNonlin 6.3 software.

[2623] As is evident from the results presented in Table 3, surprisingly in spite of the structural differences versus the prior art compounds, the compounds of the invention show high levels of NLRP3 inhibitory activity in the pyroptosis assay and in the human whole blood assay.

[2624] As is evident from the results presented in Tables 4 and 5, the compounds of the invention show advantageous pharmacokinetic properties, for example half-life T.sub.1/2, area under the curve AUC, clearance Cl and/or bioavailability, compared to the prior art compounds.

[2625] It will be understood that the present invention has been described above by way of example only. The examples are not intended to limit the scope of the invention. Various modifications and embodiments can be made without departing from the scope and spirit of the invention, which is defined by the following claims only.
