Abstract
Description
[Technical Field]
[0001] The present invention relates to dihydro-cyclopenta-isoquinoline derivatives of formula (I), methods for preparing them, pharmaceutical compositions containing them, and their use in treating disorders caused by IgE (e.g., allergic responses, non-allergic mast cell responses, or certain autoimmune responses), particularly disorders caused by the interaction between IgE and FcεRI receptors. [Background technology]
[0002] IgE (immunoglobulin E) is a member of the immunoglobulin family and mediates allergic reactions such as asthma, food allergies, type 1 hypersensitivity, and familial sinusitis.
[0003] IgE is secreted by B cells and expressed on the surface of B cells. IgE synthesized by B cells is fixed to the B cell membrane by a transmembrane domain linked to the mature IgE sequence by a short membrane-binding region. IgE also binds to B cells (and monocytes, eosinophils, and platelets) via its Fc region to the low-affinity IgE receptor (FcεRII). When mammals are exposed to an allergen, B cells that synthesize IgE that binds to the allergen are clonally amplified. This IgE is then released into circulation by B cells, where it is bound by B cells (via FcεRII) and by mast cells and basophils via so-called high-affinity receptors (FcεRI) found on the surface of mast cells and basophils. Thus, such mast cells and basophils are sensitized to the allergen. Subsequent exposure to the allergen cross-links the FcεRI on these cells and thus activates the release of histamine and other factors that cause clinical hypersensitivity and anaphylaxis.
[0004] Currently, allergic diseases, urticaria, and asthma are typically treated with one or more of the following drugs: (1) antihistamines and anti-leukotrienes that antagonize inflammatory mediators histamine and leukotrienes; (2) topical or systemic (oral or injectable) corticosteroids or immunosuppressants that suppress broad-spectrum inflammatory mechanisms; (3) short- or long-acting bronchodilators that relax the smooth muscles of narrowed airways in asthma; or (4) mast cell stabilizers that inhibit mast cell degranulation, which is usually induced by IgE binding to FcεRI; or (5) biologics that prevent IgE binding to FcεRI. The use of peptides that modulate IgE binding to FcεRI has also been explored. As an example, International Publication No. 96 / 01643 describes a peptide consisting of 4 to 50 amino acids for treating immediate-type allergic responses.
[0005] However, there remains a need to identify compounds that have therapeutic utility in treating or preventing disorders caused by IgE, particularly those caused by the interaction between IgE and FcεRI receptors. [Overview of the project]

The mixture was cooled on ice, and ice-cold sodium borohydride (100 mM in conjugation buffer) was added to obtain a final concentration of 1 mM, and incubated on ice for 60 minutes. The protein was buffer-changed using a NAP-10 column (GE Healthcare) with phosphate-buffered saline (i.e., 137 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM K₂HPO₄, pH 7.4). The degree of Alexa Fluor® 488 conjugation was determined by quantifying the material and measuring absorption at 280 nm and 497 nm. A typical conjugation ratio was Alexa Fluor® 488:sFcεR1α at 2:1.
[0186] The objective was to measure the binding of IgE-Tb to the receptor and its inhibition by a compound using an in vitro fluorescence resonance energy transfer (FRET) assay.
[0187] reagent The FRET reagents used were terbium-labeled IgE (FRET donor), Alexa Fluor® 488-labeled soluble IgE receptor FcεRIα (FRET acceptor), and Alexa Fluor® 488-labeled soluble IgE receptor FcεRIα with the Y131A mutation (FRET acceptor). Unlabeled FcεRIα was also used to generate a background control. The assay buffer consisted of 20 mM Tris pH 7.2, 150 mM NaCl, 0.002% Tween, and 1% DMSO.
[0188] Assay reaction For Examples 16 and 89, the assays were performed as follows: Each assay reaction was carried out in a 25 μl volume in a 384-well half-volume plate. Ten serial dilutions (3-fold) of the compound were prepared in DMSO at a concentration 50 times that of the final assay concentration (FAC). The compound solution was then prepared by diluting it 10-fold with IgE-Tb in assay buffer. For the assay, 5 μl of the diluted compound was added to 10 μl of IgE-Tb, followed by the addition of 10 μl of FcεRIα-Y131A-AF488. The FRET reagent FACs were 5 nM IgE-Tb and 25 nM FcεRIα-Y131A-AF488. Typically, the top FAC of the compound in the assay was 10 μM. The final DMSO concentration was 2%. The minimum signal (MIN) was measured by adding 5 μl of 1 μM unlabeled FcεRIα (FAC=200 nM) to the FRET reagent. The maximum FRET signal (MAX) was measured in a well containing the FRET reagent but without the compound.
[0189] The assay was incubated at room temperature for 2 hours, protected from light and evaporation, and gently agitated.
[0190] FRET measurement FRET measurements for each well were performed using an Envision plate reader (Perkin Elmer) by excitation at 330 nm and emission measurement at 495 / 520 nm. The FRET ratio was calculated as follows: Radiation at 520 / Radiation at 495 × 1000.
[0191] The FRET ratio was used for data analysis.
[0192] Data Analysis Z' was calculated as follows (σ = standard deviation, μ = mean): 1-((3xσ MAX )+(3xσ MIN )) / (μ MAX -μ MIN ) A Z' value greater than 0.5 was considered a good assay.
[0193] The background signal (MIN) was subtracted from all wells. Using the background subtraction value, the percentage of inhibition by the compound in each test well was calculated as follows: 100 - Test well FRET ratio / MAX FRET ratio × 100.
[0194] The inhibition percentage was plotted against the compound concentration. The IC50 value for each compound was determined using a 4-parameter logistic fit model with the XLFIT5 software package.
[0195] For Examples 1-15, 36-47, 53-62, and 64-88, assays were performed as follows: Each assay reaction was carried out in a 25 μl volume in a 384-well half-volume plate. Ten serial dilutions (3-fold) of the compound were prepared in DMSO at a concentration 50-fold of the final assay concentration (FAC). Compound solutions were then prepared by diluting 10-fold with assay buffer. For the assay, 5 μl of the diluted compound was added to 10 μl of IgE-Tb, incubated for 30 minutes, and then 10 μl of sFcER1α-Y131A-AF488 was added. The FRET reagent FACs were 5 nM IgE-Tb and 25 nM sFcER1α-Y131A-AF488. Typically, the top FAC of the compound in the assay was 10 μM. The final DMSO concentration was 2%. The minimum signal (MIN) was measured by adding 5 μl of 1 μM unlabeled sFcER1a (FAC=200 nM) to the FRET reagent. The maximum FRET signal (MAX) was measured in a well containing the FRET reagent but without the compound.
[0196] The assay was incubated at room temperature for 18 hours, protected from light and evaporation, and gently agitated.
[0197] FRET measurement FRET measurements for each well were performed using a PHERAstar FSX plate reader (BMG Labtech) by excitation at 337 nm and emission measurement at 490 / 520 nm. The FRET ratio was calculated as follows: Radiation at 520 / Radiation at 490 × 1000.
[0198] The FRET ratio was used for data analysis.
[0199] Data Analysis Z' was calculated as follows (σ = standard deviation, μ = mean): 1-((3xσ MAX )+(3xσ MIN )) / (μ MAX -μ MIN ) A Z' value greater than 0.5 was considered a good assay.
[0200] The background signal (MIN) was subtracted from all wells. Using the background subtraction value, the percentage of inhibition by the compound in each test well was calculated as follows: 100 - Test well FRET ratio / MAX FRET ratio × 100.
[0201] The inhibition percentage was plotted against the compound concentration. The IC50 value for each compound was determined using a 4-parameter logistic fit model with the XLFIT5 software package.

Ten serial dilutions (3-fold) of the compound were prepared in DMSO at a concentration 50-fold higher than the final assay concentration (FAC). Compound solutions were then prepared by 10-fold dilution with assay buffer. For the assay, 5 μl of the diluted compound was added to 10 μl of IgE-Tb, followed by 10 μl of sFcεR1α-AF488. The FRET reagent FACs were 0.75 nM for IgE-Tb and 0.9 nM for sFcεR1α-AF488. Typically, the top FAC of the compound in the assay was 10 μM. The final DMSO concentration was 2%. The minimum signal (MIN) was measured by adding 5 μl of unlabeled sFcεR1α at 1 μM (FAC = 200 nM) to the FRET reagent. The maximum FRET signal (MAX) was measured in a well containing the FRET reagent but not the compound.
[0203] The assay was incubated at room temperature for 18 hours, protected from light and evaporation, and gently agitated.
[0204] FRET measurement FRET measurements for each well were performed using a PHERAstar FSX plate reader (BMG Labtech) by excitation at 337 nm and emission measurement at 490 / 520 nm. The FRET ratio was calculated as follows: Radiation at 520 / Radiation at 490 × 1000.
