In Vitro Assessment of Peptide Substrate Cleavage by BoNTA-LC Reactions between recombinant BoNTA-LC and fluorescent peptide substrate were carried out in 96-well microplates. Reaction progress was measured continuously by increase in fluorescence at Ex =398 nm, Em=485 nm as the cleavage of the substrate relieved the quenching of DACIA fluorescence by the 2,4-dinitrophenyl-lysine. The initial velocity values for enzymatic cleavage of peptide substrate were plotted against inhibitor concentration. The points were fit by non-linear regression analysis using the graphing program Prism (GraphPad). IC50 is the inhibitor concentration that achieves half-maximal enzyme inhibition.

Assay of the Citric Acid Cycle Activation NaCT-CHO and pME-CHO were plated at 20,000 cells/well into white CulturPlate -96 (PerkinElmer) two days before the assay. Prior to assay incubation, the cultured plates were washed twice with washing buffer, 10 mM HEPES-Tris(pH7.4) containing 140 mM choline chloride, 2 mM KCl, 1 mM CaCl2, 1 mM MgCl2. The compounds to be tested were dissolved and diluted in DMSO (Wako Pure Chemical industries) to 1,000 times of a final concentration, and further diluted to two times as high as the final concentration in assay buffer, 10 mM HEPES-Tris(pH7.4) containing 140 mM NaCl, 2 mM KCl, 1 mM CaCl2, 1 mM MgCl2. The range of final concentrations was properly determined based on the test compounds activity. Each 25 μL compound solution was added to well and subsequently 25 μL radio-labeled substrate solution containing 0.4 mM (0.4 MBq/mL) [1,5-14C]-citric acid (PerkinElmer) in the assay buffer was added. After 1 hour incubation at 37° C., the reaction mixture was discarded and washed three times with pre-chilled washing buffer and then 0.1 mL MicroScint 20 (PerkinElmer) was added to well. The plate was sealed with TopSeal-A (PerkinElmer) and the radioactivity was measured using a TopCount (PerkinElmer). Non-specific activity (NS cpm) and total radio activity (Total cpm) were determined by counting of pME-CHO plated wells and NaCT-CHO plated wells without compounds, respectively. Diffusion of [14C] CO2 was able to be estimated from residual radioactivity (R cpm) by an equation (Total−R)/(Total−NS)×100(%). The difference of Total and R was disappeared in the presence of 0.1 μM antimycin A. EC50 values were calculated by regression analysis using SAS Statistical Analysis System (SAS institute Japan Ltd. Release 9.1).

CYP450 Enzyme Induction Study A final incubation system of 500 μL contained 50 μL of liver microsomes (protein concentration: 0.2 mg/mL, Corning), 1 μL of mixed specific substrates of CYP450 (CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4), 398 μL of PBS (pH 7.4), 1 μL of specific positive inhibitor (positive control) or test compound (in acetonitrile) and 50 μL of NADPH+MgCl2. Samples were prepared in duplicate of 0.5 mL for each CYP450 subtype. For each tube, the 450 μL mixed solution of substrates and enzyme and the NADPH solution were separately pre-incubated at 37° C. for 5 min.

Additionally, 2 blanks of 500 μL each were prepared in parallel without adding NADPH as the negative control group.

Assessing Antiviral Activity Against Influenza To assess their antiviral activity, some compounds were tested against murine adapted human influenza (PR8) in vitro. Canine MDCK cells were grown to confluency ( 1.0×10{circumflex over ( )}4 cells/well) in 96-well plate format in Eagle's Minimal Essential Medium (EMEM) supplemented with 10% fetal bovine serum (FBS) and 100 U/ml each of penicillin and streptomycin. Wells were washed in 1×PBS and infected with an PR8 variant expressing mCherry downstream and separated by a 2A autocleavage site from the NS-1 protein at a multiplicity of 0.01 infectious unit (IU) per cell in serum free EMEM. Assays were performed in triplicate. One hour later, virus containing medium in the cells was replaced with fresh complete medium containing the indicated compounds at 25, 12.5, 6.25, 3.13, 1.56, 0.78, 0.39 μM or the carrier in which the compounds are dissolved (DMSO) and supplemented with 2.5 μg/ml TPCK trypsin. Final concentration of DMSO was 0.5% in each treatment. Virus yield in the culture was determined at 3 days post infection by quantification of fluorescent (mCherry positive) cells in each well by fluorescent microscopy. Results were plotted using CDD Vault (CDD Vault was developed by Collaborative Drug Discovery, Inc., 1633 Bayshore Hwy, Suite 342, Burlingame, Calif. 94010) in order to calculate IC50s.

Recombinant human EGLN-1-179/426 is prepared as described above and in the Supplemental Data. Full-length recombinant human EGLN-3 is prepared in a similar way, however it is necessary to use the His-MBP-TVMV-EGLN-3 fusion for the assay due to the instability of the cleaved protein. For both enzymes, the HIF-1α peptide corresponding to residues 556-574 is used as substrate. The reaction is conducted in a total volume of 50 uL containing TrisCl (5 mM, pH 7.5), ascorbate (120 uM), 2-oxoglutarate (3.2 uM), HIF-1α (8.6 uM), and bovine serum albumin (0.01%).

A FLEXDROP (Perkin Elmer) was cleaned with ethanol then water, and primed with Buffer 2. A 384 well V bottom polypropylene plate containing d2 labelled cAMP and a second 384 well V bottom polypropylene plate containing anti-cAMP was prepared (50 ul per well). Media as "dumped~ from the cell plate and 30 uL Buffer 1 was added to each well using a Multidrop. The content of the cell plate was again "dumped" and 10 uL Buffer 2 was added to each well using a Flexdrop. 12.5 nL test compound dilutions or control compound dilutions (10 mM to 0.5 uM) were added to the cell plate using an ECHO 555 (Labcyte). The cell plate was mixed (Speed 6, Lab-Line Instruments Titer Plate Shaker) and centrifugated (1000 RPMs, 1 min). Using the Flexdrop, 2 ul additions were made into the cell plate: Buffer 2 was added to Column 24; and, 1.5 uM Forskolin was added to columns 1 through 23. Final volume of the cell plate was 12 ul with 250 nM Forskolin in all wells except column 12, and serial dilutions of test compound or control ranging from 10 uM to 0.5 nM. The cell plate was again mixed (speed 6) and centrifugated (1000 RPMs, 1 min). The cell plate was incubated for 30 minutes at room temperature (~27° C.). The contents of row P were removed and the cAMP standard dilutions were added in duplicate to Row P (P1-12 and P13-24). After incubation, 6 uL d2 labelled cAMP and 6 uL of Anti-cAMP were added to all wells of the cell plate using a BioMek FX (Beckman Coulter). The cell plate was again mixed (speed 6) and centrifugated (1000 RPMs, 1 min) and was incubated for 60 minutes in the dark at room Temp (~27° C.).

The Envision reader outputs a ratio of channel 1/channel 2 fluorescence 10,000 (Normalized signal (NS)). Amount of cAMP in nM was calculated for each well (based on NS) from a cAMP standard curve located on each plate (at P1-12 and P13-24).
