Definitions

  • This invention relates to antagonists of interleukin-4 signaling.
  • this invention relates to certain salicylate analogs that antagonize interleukin-4 signaling, to methods of making them, to pharmaceutical compositions containing them, and to their uses.
  • Interleukin-4 is a pleiotropic cytokine that is produced primarily by T helper type 2 lymphocytes (TH2 cells). The most clinically significant activity of this cytokine is the stimulation of immunoglobin class switching of the immune system's B-cells to IgE production. See P. Chomarat et al., "An update on interleukin-4 and its receptor", Eur.
  • antagonism of IL-4 can alleviate allergic responses. These include the correlation of allergy and asthma symptoms with IL-4 levels in both allergen immunotherapy and asthma patients, the reduction of spontaneous IgE production in lymphocytes following treatment with IL-4 antibodies, and the inability to induce asthma- associated eosinophilia in IL-4 gene knockout mice. Additional evidence exists correlating elevated levels of IL-4 with osteoporosis, osteoarthritis, rheumatoid arthritis, and autoimmune and other inflammation related disorders. Antagonism of IL-4 might further prove useful for therapeutically desirable immunosuppression.
  • Small molecule IL-1 antagonists have been sought. See R. Sarabu, "Design and synthesis of small molecule interleukin-1 receptor antagonists based on a benzene template, Drug Design Discovery, 15, 191-198 (1998).

To each sample (1 mL) was added 1 mL of the cell suspension; and the samples were incubated at 37 °C for 30 minutes.
  • Protein Extracts The samples were centrifuged at 800 x g at room temperature for 5 minutes. All medium was carefully removed from the cell pellet, which was placed on ice. The cells were then lysed with 50 ⁇ l of RIP A buffer containing protease and phosphatase inhibitors [150 mMNaCl, 50 ni Tris pH 8.0, 1.0% NP-40, 0.5% deoxycholate, 0.1% sodium dodecyl sulfate, 10 ⁇ g/mL aprotinin, 10 ⁇ g/mL antipain, 5 ⁇ g/mL leupeptin, 1 mg/mL Pefablock SC, 50 MNaF, 80 mM sodium glycerophosphate, and 2 m sodium vanadate (heat activated stock solution)).
  • protease and phosphatase inhibitors 150 mMNaCl, 50 ni Tris pH 8.0, 1.0% NP-40, 0.5% deoxycholate, 0.1% sodium dodecy
  • the lysed cells were let sit on ice for 5-15 minutes, the pipetted several times and transferred to microcentrifuge tubes.
  • the cells were fully lysed by carrying out 2 freeze (dry ice) thaw (room temperature) cycles or sonicating the extract on ice for 10 seconds with a probe sonicator, then centrifuged in a Brinkmann mucrocentrifuge at full speed at 4 °C for 15 minutes. The supernatant was removed and transferred to another tube; the protein extract was passed through a 26 gauge needle to completely shear all DNA in the extracts, and the protein concentration was quantitated using Bio-Rad protein assay dye reagent (Bio-Rad Laboratories, catalog #500-0006).
  • the blot was then incubated with the appropriate secondary antibody (HRP conjugated goat anti-rabbit antibodies, Zymed, South San Francisco, CA) at 1:1000 in 0.5% NFDM in TBST for 2 hr at RT, and washed twice with TBST for 15-30 minutes each at room temperature.
  • the blot was developed using ECL (Amersham International) plus Western blotting detection reagents in accordance with the manufacturer's instructions, and exposed to single emulsion Biomax film for 10 seconds to 10 minutes.
  • Receptor Coated Plates Dispense 100 ⁇ L of 10 ⁇ g / mL NeutrAvidin (in 50 mM sodium carbonate, pH9) to Nunc Microsorp 96-well microtiter plates. Incubate overnight at 4°C to coat. Shake out solution and blot excess liquid from the inverted and tapped plate.- Immediately add 200 ⁇ L SuperBlock (Pierce) per well. Shake hard briefly to block upper part of each well, then shake gently for 30 minutes. Again shake out solution and blot. Use a plate washer to rinse all the plates with a single 4 cycle rinse to remove residual avidin (use a program that leaves rinse solution in wells at end).
  • Assay Rinse the receptor coated plates with a single 4 cycle rinse (use a program that leaves rinse solution in wells at end). After a 30 minute pre-incubation of the resuspended compound plates, shake and blot the rinsing solution from one of the receptor coated plates. Transfer 100 ⁇ L from each well of the compound plate to the same well of this receptor coated plate. Repeat for each plate so that the pre-incubation time of the compound solution is the same 30 minutes.
