Assay: Inhibition of the Activation Assay: As human TLR7 expressing cell line, HEK293 cell line was bought from IMGENEX Corporation (TLR7/NF-ηB/SEAPorter HEK293 cell), which is human embryonic kidney cell line and stably expresses full-length human TLR7 gene and secreted alkaline phosphatase (SEAP) reporter gene under the transcriptional control of an NE-ηB response element. The TLR7/NF-ηB/SEAPorter HEK293 cell was cultivated with DMEM containing 10% fetal bovine serum (FBS) and 10 μg/mL blasticidin S at 37° C. in the presence of 5% CO2. The TLR7/NF-ηB/SEAPorter HEK293 cell was seeded into 96-well microtiter plate at 5×104 cell/90 μL/well, and the place was cultivated at 37° C. in a CO2 incubator overnight. Each test compound that was diluted with the medium was added to the wells (10 μL/well), wherein each final concentration was adjusted to 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, and 10 μmol/L, or 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, and 100 μmol/L. After 0.5 hour, R-848 that is TLR7/8 ligand was added to each well (10 μL/well), wherein each final concentration was adjusted to 200 nmol/L. The total volume was adjusted to 110 μL/well, the test samples were incubated in CO2 incubator for 20±1 hours, and then the SEAP activity was measured as activation of TLR7. The SEAP activity was evaluated as follows: p-nitro-phenyl phosphate (pNPP) (Invitrogen) was added to the incubated sample (50 μL/well); after 15 minutes, 4 mol/L sodium hydroxide solution (nacalai tesque) was added thereto (50 μL/well) to quench the reaction; and the absorbance of each sample was measured at 405 nm with microplate reader Elx808 (BioTek). The 50% inhibitory concentration (IC50 value) of each sample compound was calculated based on 100% of the SEAP activity wherein the test sample comprises no sample compound.

Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at a final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Blue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Assay: High Throughput Biochemical Assay: EGFR activity was measured using KinEASE (Cisbio), a time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay. In this assay, EGFR-catalyzes the phosphorylation of a universal Tyrosine kinase peptide substrate labeled with XL665. Europium conjugated phosphor-tyrosine specific antibody binds the resulting phosphorylated peptide. Formation of phosphorylated peptide is quantified by TR-FRET with Europium as the donor and XL665 the acceptor. The assay was performed in two main steps. The first step is the kinase reaction step and the second step is the detection step with TR-FRET reagents. In brief, test compounds 1:3 serially diluted in DMSO were delivered into Corning white, low volume, non-binding 384 well plates using the Echo 550 acoustic liquid dispenser (Labcyte®). EGFR enzyme (Human EGFR, cytoplasmic domain [669-1210] from Carna Biosciences Cat. No. 08-115) and substrates TK substrate-biotin (included in Cisbio HTRF KinEASE-TK kit Cat. No. 62TK0PEJ) were dispensed into assay plates using a Multi-Flo (Bio-Tek Instruments). The standard 10 μL reaction mixture contained 6 μM ATP (1×Km) or 12 μM ATP (2×Km), 1 μM biotinylated peptide, 0.3 nM EGFR (for 1×Km ATP) or 0.1 nM EGFR (for 2×Km ATP) in reaction buffer (10 mM MOPs, pH 7.0, 1.5% Glycerol, 0.5 mg/ml BSA, 10 mM Mg-Acetate, 1 mM DTT, 0.025% NP-40). After 60 min of incubation at room temperature, 10 μL of Stop and Detect Solution (1:400 Europium Cryptate labeled anti-phosphorylated peptide antibody solution and 125 nM strepavidin-XL665 Tracer in a 50 mM Hepes pH 7.0 detection buffer containing sufficient EDTA) was added. The plate was then further incubated for over 60 minutes at room temperature and read using an Envision 2103 Multilabeled reader (PerkinElmer) with excitation/emission/FRET emission at 340 nm/615 nm/665 nm, respectively.

HEPES buffer was purchased from Gibco. ABL1 kinase and Abltide were purchased from Signalchem.c-Abl kinase activity was measured by Promega's ADP-Glo Assay. In this assay, His-tagged recombinant human ABL1 (0.25 ng/μl) is incubated with 5 μL of compounds (0.5% DMSO), 5 μL of Abltide (0.01 μg/μl) and 5 μL of ATP (25 μM) in buffer (50 mM HEPES, 7.5; 10 mM MgCl2; 1 mM EGTA; 0.05% BSA; 0.01% Triton X-100; 2 mM DTT). The assay was started by incubating the reaction mixture in a 96-well plate at 30° C. for 30-min. After the incubation, 25 μL ADP-Glo reagent was added and the reaction was incubated at room temperature for 40-min to stop the reaction and degrade residual ATP. The ADP product was then converted to ATP by adding 50 μL per well of detection reagent. Luminescence was detected after 30-min room temperature incubation with the Molecular device I3X plate reader. The IC50 values were calculated from a series of percent inhibition values determined at a range of inhibitor concentration using software routines as implemented in the GraphPad Prism 7 software and Sigma Plot 13.0.

Compound (SMILES): OC[C@H]1O[C@@H](c2nncn2-c2ccc3c(Cl)nsc3c2)[C@H](O)[C@@H](n2cc(-c3cc(F)c(F)c(F)c3)nn2)[C@H]1O
InChIKey: BANJSWDGLADROK-YNUHATHGSA-N
Target: Galectin-3 (SINGLE PROTEIN), Homo sapiens
UniProt: P17931
Assay: Biological Assay: The Gal-3 assays were performed in 384 white Opti plates in three replicates at room temperature with gentle shaking at 250-300 rpmFrom the original stocks, 2.525× working stock concentrations of His-tagged recombinant human Gal-3 (hGal-3) and that of B-ASF were prepared. From the working stock, 20 μl of hGal-3 (15 nM) and 20 μl B-ASF (15 nM) were added to the plates. In Negative Control, only hGal-3 was added. A concentration range of 50× working stocks were prepared for the compounds in 100% DMSO. Aliquots of 1 uL of the compounds were added to the wells and pre-incubated with 20 μl hGal-3 per well for 30 minutes Then 20 μl B-ASF wereadded and incubated for another 1 hour. To detect the signal, 5 μL (final conc. of 1.0 nM) terbium labelled Anti-His antibody was added and incubated for 30 min followed by adding 5 μL (final conc. of 20 nM) Streptavidin d2 and incubation for another 1 hour. The assay signal was detected using HTRF screen protocol (Excitation wavelength=340 nm, emission wavelength=615 nm/665 nm) on Envision 2104 Multilabel Reader.
