    Pharmacological Activity Test Example

    Example 1 Activity Test at Molecular Level:

    1. LSD1 In Vitro Activity Assay

    [0404] Screening method: lysine-specific demethylase 1 (LSD1) activity screening
    Instrument: microplate reader Envision (PerkinElmer, USA).
    MATERIALS: Human recombinant LSD1, the LSD1 protein fragment fused with GST (aa158-end) was expressed and purified by E. coli expression system by the laboratory in house.

    [0405] LSD1 Activity Detection Kit LANCE Ultra LSD1 Histone H3-Lysine 4 Demethylase Assay was purchased from Perkin Elmer;

    [0406] The H3 polypeptide substrate ARTK(me1)QTARKSTGGKAPRKQLA-GG-K(Biotin)-NH2 was synthesized by Jill Biochemical Company.

    Principle: LSD1 specifically removes the methylation modification at the K4 lysine on the H3 polypeptide substrate, making it a substrate without methylation modification. The method employs a histone H3 methylated polypeptide (1-24) as a substrate to introduce a biotin label in the C segment of the substrate. LSD1 initiates the reaction with the participation of FAD to remve the methylation modification on the substrate H3K4. The Eu-labeled H3K4 background antibody binds to the substrate by antigen-antibody reaction, while the streptavidin-labeled receptor is bounded by the specific interaction of streptavidin and biotin. This allows the Eu-labeled donor to interact with the streptavidin-labeled receptor. In fluorescence resonance energy transfer, when two fluorophores are brought close due to biomolecular interaction, part of the energy captured by the cryptate at the time of excitation will be released, the emission wavelength of which is 620 nm; the other part of the energy is transferred to the receptor (acceptor), the emission wavelength of which is 665 nm. The 665 nm emission is only produced by FRET caused by the donor. Therefore, when biomolecules interact, there are two excitation lights at 620 nm and 665 nm; when there is no interaction, there is only one excitation light at 620 nm. The LSD1 demethylation activity was reflected by detecting the ratio of the fluorescence signals at the two emission wavelengths of 665 nm and 620 nm. Meanwhile, a blank control was set to determine the strength of the enzyme activity. ORY-1001 and GSK-2879552 were employed as positive inhibitors in the experiment.
    Sample processing: Samples were dissolved in DMSO, stored at low temperature, and the concentration of DMSO in the final system was controlled within a range that won't affect the activity of the assay.
    The activity of the sample was tested by primary screening at a single concentration, for example 20 M. For samples exhibiting activity under certain conditions, for example, the inhibition rate (% Inhibition) being greater than 50, the active dose-dependent relationship, i.e., the IC50 value, was obtained by nonlinearly fitting the sample activity vs sample concentration, the software used for the calculation was Graphpad Prism 5, the model used for fitting was sigmoidal dose-response (variable slope), and for most inhibitor screening models, the bottom and top of the fitted curve were set to 0 and 100.

    2. MAOA and MAOB In Vitro Activity Experiments

    [0408] Screening method: Monoamine oxidase MAOA and MAOB activity screening
    Instrument: microplate reader Envision (PerkinElmer, USA).
    MATERIALS: Human recombinant MAOA, purchased from Promega; human recombinant MAOB, purchased from Sigma;

    [0409] The MAOA and MAOB activity assay kit MAO-Glo was purchased from Promega. Principle: This method uses a specific luciferin derivative as a substrate, MAOA or MAOB can catalyze the conversion of substrate to luciferin methyl ester, and the product, luciferin methyl ester can produce fluorescence under the action of luciferase, thus reflecting the activity of MAOA or MAOB by the intensity of the fluorescent signal. Meanwhile, a blank control was set to determine the strength of the enzyme activity. Tranylcypromine (TCP) was employed as a positive inhibitor in the experiment.

    Sample processing: Samples were dissolved in DMSO, stored at low temperature, and the concentration of DMSO in the final system was controlled within a range that won't affect the activity of the assay.
    The activity of the sample was tested by primary screening at a single concentration, for example 100 M. For samples exhibiting activity under certain conditions, for example, the inhibition rate (% Inhibition) being greater than 50, the active dose-dependent relationship, i.e., the IC.sub.50 value, was obtained by nonlinearly fitting the sample activity vs the sample concentration, the software used for the calculation was Graphpad Prism 5, the model used for the fit was sigmoidal dose-response (variable slope), and for most inhibitor screening models, the bottom and top of the fitted curve were set to 0 and 100.

    Experimental Principle:

    [0411] Quantitative Real-time PCR is a method for measuring the total amount of the product after each polymerase chain reaction (PCR) cycle by using fluorescent chemicals in a DNA amplification reaction. Quantitative analysis of a specific DNA sequence in a sample to be tested was conducted by internal reference method or external reference method. There is a linear relationship between the Ct value of the template and the initial copy number of the template during the exponential phase of PCR amplification, which serves as a basis for quantification.

[0413] 2. 3 L of the test compound or positive compound was added to 147 L of medium, mixed well, and 100 L was taken and added to the 12-well plate with the cells, mixed, and incubated at 37 C., for 24 h in an incubator in 5% CO.sub.2. [0414] 3. The sample was transferred to a 1.5 mL EP tube, centrifuged at 2000 rpm for 3 min, and the supernatant was removed. 500 mL of trizol was added for lysis and allowed to stand for 3 min. [0415] 4. 100 L of chloroform was added and the EP tube was vigorously shaken for 15 s, and allowed to stand for 3 min, 12000 rpm, 15 min. [0416] 5.

The supernatant was removed, and 500 L of 4 75% ethanol was added and mixed, the mixture was centrifuged at 7,500 rpm for 10 min. [0418] 7. The supernatant was removed, and the EP tube was air-dried in a fume hood. 20-30 L of RNase inactivated deionized water was added and mixed to measure the RNA concentration. [0419] 8. All samples were uniformly adjusted to 750 ng/8 L, and RT-kit enzyme and substrate were added, reverse transcription was performed for 15 min under 42, and enzyme inactivated at 85 for 2 min. [0420] 9. 100 L of deionized water was added to the EP tube and mixed. [0421] 10. The QPCR sample was prepared at a ratio of 7.6 L sample+0.65 L forward primer+0.65 L reverse primer+11.1 L SYBR and placed in an eight-tube tube, centrifuged at 1500 rpm for 1 min, and then QPCR was started.
