2. BIOLOGICAL AND STRUCTURAL CHARACTERIZATION OF THE COMPOUNDS

[0906] The following is a description of biological and structural characterization of the compounds herein below, which provides experimental data supporting the invention and means of performing the invention, as non-limiting examples.

2.1. NEDD4 Inhibition

[0907] The NEDD4 inhibitors according to the invention are capable of inhibiting or decreasing the functional activity of the ligase. In the present study, two different in vitro ubiquitination assays have been conducted, one to quantitatively determine the potency of the different exemplary compounds (TR-FRET assay) and another one to determine their selectivity (western blot assay).

In Vitro Ubiquitination Assay TR-FRET Based

[0908] In order to quantitatively measure the self-ubiquitination process of the E3 HECT ligase NEDD4 the inventors employed a TR-FRET based assay. TR-FRET technology exploits the long-lasting emission of lanthanide fluorescence to interpose a short time-delay between FRET donor excitation and emission. This phenomenon enables to isolate real fluorescent signals from short-lived background emissions, thus reducing possible interference from compounds.

[0909] In the present study, elongation of the ubiqutin chain by NEDD4 is measured by adding bacterially expressed E1, His-tagged UBE2D3 (E2) and untagged HECT of NEDD4 wild-type (WT) (E3 ligase) (named in FIG. 1 as WT) enzymes to a mixture of Eu-cryptate ubiquitin, Cy5-ubiquitin and wild-type ubiquitin, combined in a ratio optimized for TR-FRET based conjugation (100× TRF-Ubiquitin Mix, SBB-TR0051). As a negative control, a catalytically inactive (Cys867/Ala) HECT NEDD4 mutant named in FIG. 1 as C/A is used. Bacterially expressed E1, His-tagged UBE2D3 (E2), untagged HECT NEDD4 (E3 ligase) WT and NEDD4 C/A enzymes were produced and purified as reported in E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016).

[0910] Enzymatic incorporation of the labeled TRF-Ubiquitin mix into chains leads to an increase in fluorescence emission at 665 nm (emission of the acceptor Cy5-Ubiquitin, Emacceptor) and decrease at emission wavelength 620 nm (emission of the donor Eu-cryptate Ubiquitin, Emdonor).

[0911] The assay was performed in a 384-well plate format (Optiplate, Perkin Elmer, #6007290) on an automated liquid-handler (Hamilton STAR, Hamilton Robotics, Switzerland).

[0912] All compounds were dissolved in 100% DMSO and serially diluted in 96-well plates (from 100 μM to 0.005 μM).

[0913] Briefly, all reagents were thawed and kept on ice. A master mix containing E1, E2, E3 and TRF-Ubiquitin Mix (SBB-TR0051) diluted in the assay buffer (Tris-HCl pH 7.6 25 mM, NaCl 100 mM, MgCl.sub.2 5 mM and Tween 0.01%) is prepared and 50 μl/well is dispensed in a 384 well plate. 3 μl of compounds dissolved in DMSO in the above-indicated concentration range were added and pre-incubated for 1 hour. Final E1, E2 and E3 concentrations in the assay buffer (Tris-HCl pH 7.6 25 mM, NaCl 100 mM, MgCl.sub.2 5 mM and Tween 0.01%) were 30, 350 and 50 nanomolars, respectively. The reaction was initiated with the addition of ATP (22 μl of 2 mM ATP, JenaBioscience, NU-1010) and was allowed to proceed for 120 minutes, measuring fluorescence emission at 665 nm and 620 nm in real-time on an EnSpire microplate reader (Perkin Elmer).

[0914] Kinetic raw data were analyzed by Area Under the Curve (AUC) method using Prism GraphPad software.

[0915] % signal/background corresponds to the following equation:

(Experimental signal−Background signal)/Background signal×100%

[0916] Experimental signal corresponds to the signal obtained by the enzymatic reaction in presence of the vehicle (DMSO) and/or the different compound concentrations. Background signal corresponds to the signal obtained by the enzymatic reaction in absence of ATP.

[0917] The relative potency of the compounds was evaluated by dose-response curves following the enzymatic reaction of HECT NEDD4 WT in real time for 120 minutes.

[0918] Percentage of inhibition is then determined by the equation:

% inhibition=100×[1−(X)/(MAX)],

[0919] where MAX correspond to AUC of the vehicle (DMSO) treated enzyme, and X corresponds to the AUC of the compound treated enzyme.

[0920] Example of the performed assay with compound 12 is reported in FIG. 1. As reported in FIG. 1, a dose dependent inhibition of enzymatic activity is determined by compound 12. The concentrations of compound 12 used are indicated in the figure. The catalytic inactive mutant (C/A) validates the assay showing almost no TR-FRET signal (considered as background level).

[0921] Compounds 16-21, 25, 31, 33, 55 and 101 exhibit percentages of inhibition lower than 30% at 11 μM, compounds 1, 3, 11, 23, 52 and 66 exhibit percentages of inhibition between 30% and 50% at 11 μM, and compounds 2, 4-6, 7-10, 12-15, 22, 24, 26-30, 32, 34-51, 53-54, 56-65, 67-83, 85-100 and 102 exhibit percentages of inhibition higher than 50% at 11 μM.

2.2 Determination of the Structure of NEDD4 HECT in Complex with Compound 12

[0922] The inventors obtained by X-Ray the crystal structure of the HECT domain of NEDD4 in complex with compound 12.

[0923] For crystallization studies, the cleaved HECT of NEDD4, produced as previously described (E. Maspero et al. EMBO Rep. 12(4):342-9 (2011)), was concentrated in Vivaspin concentrators (MW cut-off 30 kDa, Sartorius Stedim Biotech) and loaded onto a Superdex 200 size exclusion chromatography column (GE Healthcare) equilibrated with size exclusion buffer (20 mM Tris-HCl, pH 8.0, 200 mM NaCl, 1 mM EDTA, 1 mM DTT, 5% glycerol). The protein was eluted within the above indicated buffer in a clear, well isolated, peak according to its size and shape. Purity of the peak can be assayed by SDS-PAGE gel. The desired fractions were collected, pooled, and concentrated as needed using Vivaspin tubes.

[0924] Crystals of NEDD4 HECT were grown in hanging drops in 24 wells with the vapour diffusion technique. Drops were set up mixing 1 μl of protein solution in size exclusion buffer at ca. 10 mg/ml with 1 μl of reservoir solution containing 100 mM MES pH 6.0, 6-10% PEG 400, 90 mM MgCl.sub.2, 5 mM TCEP. Nicely diffracting crystals were obtained by microseeding the drops after an overnight equilibration. Crystals of the complexes were obtained soaking the HECT crystals with the compounds, adding to the crystal drops 1-2 μl of a cryoprotectant solution containing 100 mM MES pH 6.0, 8-10% PEG 400, 20% glycerol, 1-4 mM compound 12 (0.25-1% DMSO). Crystals were harvested and cryo-cooled in liquid nitrogen after few hours or overnight soak and used to determine the three dimensional structure of the inhibitor-bound NEDD4 HECT domain as described in E. Maspero et al. EMBO Rep. 12(4):342-9 (2011). HECT NEDD4 N-lobe and C-lobe models, from pdb entry 2xbf (version 1.2, 13-07-2011), independently, were used as search models for molecular replacement. As shown in FIG. 2, compound 12 binds to the N-lobe of the NEDD4 HECT domain by burying its dibenzazepine and the Cl moiety into a hydrophobic pocket shaped by Leu553, Tyr557, Met600, Tyr605, Leu607, Tyr634, Phe637 and IIe638 and flanked by polar residues Glu554 and Asn628. Furthermore, the α,β-unsaturated ester of compound 12 is attacked by the thiol group of Cys627 generating a covalent link to the protein.

[0925] The overall conformation of NEDD4 HECT in complex with compound 12 is virtually identical to the previously reported apo structure of NEDD4 (pdb entry 2xbf, version 1.2, 13-07-2011, E. Maspero et al. EMBO Rep. 12:342-9 (2011)) with few exceptions in the pocket region. As shown in FIG. 3, major rearrangements occur at the level of the side chains of Tyr634 and Glu554, which move in order to accommodate the dibenzazepine moiety, and of the main and side chain of Cys627, to which the compound is covalently bound. Moreover, Asn628 side chain is tilted: rather than pointing towards Tyr634, which is displaced, it forms a hydrogen bond with the amino group present in the side chain of compound 12.

2.3. Compounds Selectivity

In Vitro Ubiquitination Assay Detected by Western Blot

[0926] An in vitro ubiquitination assay followed by western blot detection was used to determine the selectivity of the different compounds. The full protocol is described in (E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016)). Briefly, the assay was performed with bacterially purified enzymes (20 nM E1, 250 nM of purified His6-tagged UBE2D3 and 250 nM untagged HECT of NEDD4 WT or NEDD4 L553F or NEDD4L WT) and 1 μM of untagged ubiquitin in ubiquitination buffer (25 mM Tris-HCl, pH 7.6, 5 mM MgCl.sub.2, 100 mM NaCl, 0.2 μM DTT). Compounds dissolved in DMSO were added at the final concentration of 10 μM (final DMSO concentration 2%) and pre-incubated for 1 hour at room temperature. Reactions were started by addition of ATP (2 mM final concentration), incubated at 25° C. for 30 or 60 minutes and stopped by addition of 2× Laemmli sample buffer (4% SDS, 125 mM Tris pH 6.8, 20% glycerol, 0.002% saturated bromophenol blue, 200 mM DTT). Bacterially expressed E1, His-tagged UBE2D3 (E2), untagged HECT of NEDD4 (E3 ligase) WT or L553F or NEDD4LWT enzymes and untagged Ub WT were produced and purified as reported in E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016). Detection was performed by immunoblotting using anti-Ub antibody (P4D1, Santa Cruz, sc8017). NEDD4 inhibitors described in the invention are capable of inhibiting NEDD4 but not NEDD4L as visible in FIG. 4a where the indicated compounds at 10 μM concentration were tested on the HECT domain of NEDD4 WT and NEDD4L WT. Anti-ubiquitin immunoblot clearly indicates the ability of the reported compounds to almost completely abolish the activity of HECT NEDD4 WT respect the vehicle-treated sample (indicated as −). Differently and importantly, the compounds were unable to inhibit the HECT of NEDD4L WT. This selective inhibition depends on the exquisite binding specificity of the compounds. The binding pocket determined by X-ray is highly conserved among the various members of the NEDD4 family with few important exceptions. In particular, Leu553 of NEDD4 corresponds to a sterically bulkier phenylalanine residue, Phe608 in NEDD4L that is predicted to impede the binding of NEDD4 inhibitors (FIG. 4b).

[0927] To demonstrate the importance of this residue for compound specificity, the inventors generated the NEDD4 mutant L553F, introducing the phenylalanine residue in the context of NEDD4 protein and tested its activity with compound 12. As shown in FIG. 4c, this single point mutation is sufficient to fully abrogate the activity of compound 12.

In Vitro Ubiquitination Assay TR-FRET Based

[0928] To determine the selectivity of identified NEDD4 inhibitors, it was quantitatively measured the self-ubiquitination process of the E3 HECT ligase belonging to NEDD4 family such as NEDD4L, HECW2 and ITCH in presence or not of some compounds such as 5, 9, 12, 29, 42, 45, 56, 58, 61, 77, 78, 85 and 94 employing TR-FRET based assays.

NEDD4L

[0929] The assay was performed as described above in the paragraph titled “In vitro ubiquitination assay TR-FRET based” under the heading “2.1. NEDD4 UBIQUITINATION ASSAYS” using untagged HECT of NEDD4L (E3 ligase) instead of untagged HECT of NEDD4 wild-type (WT) (E3 ligase). In this case, final E1, E2 and E3 concentrations in the assay buffer (Tris-HCl pH 7.6 25 mM, NaCl 100 mM, MgCl.sub.2 5 mM and Tween 0.01%) were 30, 350 and 31.3 nanomolars, respectively. Untagged HECT NEDD4L (E3 ligase) enzyme was produced and purified as reported in E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016) and in E.

[0930] Maspero et al. EMBO Reports 12:342-349(2011).

HECW2

[0931] The assay was performed as described above in the paragraph titled “In vitro ubiquitination assay TR-FRET based” under the heading “2.1. NEDD4 UBIQUITINATION ASSAYS” using His-MPB tagged HECT of HECW2 (E3 ligase) instead of untagged HECT of NEDD4 wild-type (WT) (E3 ligase). In this case, final E1, E2 and E3 concentrations in the assay buffer (Tris-HCl pH 7.6 25 mM, NaCl 100 mM, MgCl.sub.2 5 mM and Tween 0.01%) were 30, 350 and 62.5 nanomolars, respectively. His-MPB tagged HECT of HECW2 (E3 ligase) enzyme was produced and purified as reported in E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016) and in E. Maspero et al. EMBO Reports 12:342-349(2011).

ITCH

[0932] The assay was performed as described above in the paragraph titled “In vitro ubiquitination assay TR-FRET based” under the heading “2.1. NEDD4 UBIQUITINATION ASSAYS” using untagged HECT of ITCH (E3 ligase) instead of untagged HECT of NEDD4 wild-type (WT) (E3 ligase). In this case, final E1, E2 and E3 concentrations in the assay buffer (Tris-HCl pH 7.6 25 mM, NaCl 100 mM, MgCl.sub.2 5 mM and Tween 0.01%) were 30, 350 and 60 nanomolars, respectively. Untagged HECT of ITCH (E3 ligase) enzyme was produced and purified as reported in E. Maspero et al. Methods Mol Biol. 1449:153-60 (2016) and in E. Maspero et al. EMBO Reports 12:342-349(2011).

[0933] Regarding NEDD4L, compounds 9, 58, 61, 78 and 85, exhibit a percentage of inhibition lower than 5% at 11 μM, compounds 5, 42, 94, 77 and 12 exhibit a percentage of inhibition lower than 15% at 11 μM, compounds 29, 56 and 45 exhibit a percentage of inhibition lower or equal to 20% at 11 μM.

[0934] Regarding HECW2, compounds 9, 58, 85, 61, 78 and 12 exhibit a percentage of inhibition lower than 5% at 11 μM, compounds 5, 29, 42, 56, 94 and 77 exhibit a percentage of inhibition lower than 15% at 11 μM, compound 45 exhibits a percentage of inhibition lower to 20% at 11 μM.

[0935] Regarding ITCH, compounds 12, 29, 61, 77 and 45 exhibit a percentage of inhibition lower than 5% at 11 μM, compounds 5, 42, 56, 58 and 94 exhibit a percentage of inhibition lower than 15% at 11 μM, compounds 78 and 9 exhibit a percentage of inhibition lower to 20% at 11 μM, compound 85 exhibits a percentage of inhibition lower than 25% at 11 μM.

[0936] Overall the data obtained on the enzymes belonging to NEDD4 family such as NEDD4L, ITCH and HECW2, revealed that the compounds have a good selectivity profile and particularly the compounds showed a clear and strong preferential inhibitory activity versus NEDD4 respect ITCH, NEDD4L and HECW2.

2.4. Cell Growth

[0937] CellTiter-Glo® Luminescent Cell Viability Assay (Promega, Catalog number: G7571) is a homogeneous method of determining the number of viable cells in culture based on quantitation of the present ATP, which indicates the presence of metabolically active cells. The homogeneous assay procedure involves addition of a single reagent (CellTiter-Glo® Reagent) directly to the cells, which leads to cell lysis and generation of a luminescent signal proportional to the amount of the ATP and the number of cells present in culture. The assay relies on the properties of a proprietary thermostable luciferase (Ultra-Glo® recombinant luciferase), which generates a luminescent signal.

[0938] DU145 cells (obtained from CLS Cell Lines Service GmbH item 300168) were grown in DMEM (Sigma Aldrich catalog number D6171-500 ml) supplemented with 10% Fetal Bovine Serum (Euroclone, catalog number. ECS0180L), 2 mM L-Glutamine (Euroclone catalog number LOBE17605F) and 100 U/ml penicillin-0.1 μg/ml streptomycin (EuroClone, ECB3001L). LNCaP cells (obtained from CLS Cell Lines Service GmbH item 300265) were grown in RPMI1640 (Lonza catalog number BE12-167F) supplemented with 10% Fetal Bovine Serum (Euroclone, catalog number. ECS0180L), 2 mM L-Glutamine (Euroclone catalog number LOBE17605F) and 100 U/ml penicillin-0.1 μg/ml streptomycin (EuroClone, ECB3001 L).

[0939] To determine the antiprolifeartive activity of the compounds, 3000 DU145 cells and 5000 LNCap cells were seeded in 96 multiwell plate (Sigma catalog number CLS9102) per well. 24 hours after seeding, the cells were incubated for 48 hours with different concentrations of the inhibitors (from 50 to 0 μM with a 3-fold dilution) dissolved in DMSO. After 48 hours, a volume of CellTiter-Glo® Reagent equal to the volume of cell culture medium was added. The content was mixed for 2 min to induce cell lysis. The luminescence was measured and recorded with Tecan Infinite 200 multimode plate reader after further 10 min at room temperature in order to obtain a stable luminescent signal.

[0940] The IC.sub.50 was calculated using GraphPad Software from the recorded luminescent signal.

[0941] The obtained results are reported in Table 1:
