Description
TECHNICAL FIELD

The present invention relates to a dialkoxynaphtho[2,3-c]furan-1(3H)-one derivative and a pharmaceutical composition including the same.


BACKGROUND ART

The Justicia genus of the Acanthaceae family consists of about 600 species. Representative Justicia genus plants include Justicia procumbens, Justicia pectoralis, Justicia gendarussa, Justicia anselliana, Justicia adhatoda, and the like. Among them, Justicia procumbens, which is a yearly plant, includes Justicidin A (9-(1,3-benzodioxol-5-yl)-4,6,7-trimethoxy-3H-benzo[f][2]benzofuran-1-one), Justicidin B (4-(1,3-benzodioxol-5-yl)-6,7-dimethoxy-1H-benzo[f][2]benzofuran-3-one), and the like as active ingredients, and grows in Korea, Japan, China, India, etc. Existing therapeutic agents for allergic diseases include steroids which suppress immune responses, but are limited to a local or temporary use due to various side effects caused by non-selective immune suppression. Anti-leukotrienes, anti-histamines and the like are the most commonly used therapeutic agents for allergic diseases, but are involved in controlling at the lower stages of the allergy-inducing mechanism, and thus have a limitation in that they have an effect of temporarily alleviating symptoms. In particular, anti-leukotrienes do not have a good medicinal effect on the treatment of asthma as compared to inhaler corticosteroid (ICS), and thus their use are limited only to patients who cannot use inhalant agents, patients who have side effects on ICS, or asthma patients with allergic rhinitis (Workshop report, global strategy for asthma management and prevention (updated 2017). The GINA reports are available on www.ginasthma.org.). Besides, there is an anti-IgE antibody therapeutic agent (Omalizumab) which is used as a therapeutic agent for severe asthma, and anti-IL-5 antibody therapeutic agents (Mepolizumab, Reslizumab) have been recently developed, but there is a need to develop a new concept of therapeutic agent effective for allergic diseases due to high costs and a limited improvement effect on severe asthma patients (Corren J, Weinstein S, Janka L, Zangrilli J, Garin M. Phase 3 study of reslizumab in patients with poorly controlled asthma: Effects across a broad range of eosinophil counts. Chest. 2016, 150 (4): 799-810, Djukanović R, Wilson S J, Kraft M, Jarjour N N, Steel M, Chung K F, Bao W, Fowler-Taylor A, Matthews J, Busse W W, Holgate S T, Fahy J V.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) refers to a severe acute respiratory syndrome coronavirus 2, which has been first known in 2019, and is classified as a positive-sense single-stranded RNA virus. The disease infected by this virus has been named Coronavirus infection disease-19 (Coronavirus disease 2019), and is also called COVID-19 for short. The World Health Organization (WHO) has officially announced a coronavirus pandemic. As of November 2020, it has been found that the number of infected people in South Korea is more than 27,000, and about 47.4 million people are infected around the world and this trend continues to spread. Currently, Remdesivir, an Ebola virus therapeutic agent, is the only one formulated as a therapeutic agent for COVID-19, but its effect has been questioned, and plasma treatment, etc., is used as an alternative therapy. In addition, clinical trials for COVID 19 have been conducted on Kaletra (main ingredient: Lopinavir), a human immunodeficiency virus (HIV) therapeutic agent, etc. Accordingly, there is an urgent need for developing a therapeutic agent for SARS-Cov-2.

Experimental Example 1. Comparative Experiment for Inhibitory Effect on SARS-COV-2 Infection in Vero Cell Line

In order to confirm the inhibitory effect of the novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives against SARS-COV-2 infection, the Vero cell line was cultured for 24 hours, dosed with example compounds at ten concentrations ranging from 0.1 micro M (micro gram) to 50 micro M, and infected with the SARS-COV-2 provided from the Korea Centers for Disease Control and Prevention (KCDC). Specifically, the Vero cells were seeded at 1.2×104 per well into a 384-well tissue culture plate. On the next day, the compound at a concentration of 50 micro M was serially diluted two-fold to prepare compounds at ten concentrations and treated with Vero cells. Soon after, the cells treated with the compound were infected with SARS-COV-2 (COVID 19) and cultured at 37° C. for 24 hours. Then, the cells were fixed and permeabilized. After that, the cells were treated with anti-SARS-COV-2 Nucleocapsid (N) primary antibody and then stained by treatment with Alexa Fluor 488-conjugated IgG secondary antibody and Hoechst 33342. Fluorescent expression was obtained using an Operetta large image analyzer (Perkin Elmer). The resulting image were used with Columbus software to calculate the percentage of infected cells and measure the inhibitory efficacy of the drug, which were then summarized in Table 2, and the response curve and 50% inhibitory effect (IC50) values according to the drug concentration are derived with XLFit (IDBS) software, and the results and cytotoxicity (CC50) of the test substances are summarized in Table 1 and FIGS. 1 to 18. FIGS. 1 to 18 are graphs showing the SARS-COV inhibitory activity and cytotoxicity of some of the drugs of each Example listed in Table 1 below. In the graphs of FIGS. 1 to 18, a horizontal axis represents the drug concentration (μM) expressed by log values, and a vertical axis represents the SARS-COV-2 inhibition rate (%) and the cell survival rate (%) (in FIGS. 1 to 18. ▴ represents CC50, and ● represents IC50).

Experimental Example 2. Comparative Experiment for Inhibition of IL-5 Expression in Th2 Cells

In order to confirm the inhibitory effect of the novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives against IL-5 expression, Th2 cells were cultured using mouse splenocytes, and dosed with the test drugs prepared in Examples 1 to 95 at a concentration of 1 nM, so that IL-5 was measured through an ELISA test. Specifically, after spleens were collected from Balb/C mice, CD4+ T cells were isolated therefrom and were seeded at 1-2×106 per well into a 48-well tissue culture plate coated with anti-CD3 (5 ug/ml) and anti-CD28 (1 ug/ml). At this time, the culture medium was incubated with IL-2 (20 ng/ml), IL-4 (100 ng/ml), anti-IFNγ (10 ug/ml), anti-IL12 (10 ug/ml), and a derivative of 1 nM for two days, transferred to a new tissue culture plate, and further cultured for three days to induce differentiation into Th2 cells. After replacing with a new medium containing anti-IFNγ (10 ug/ml), anti-IL12 (10 ug/ml) and a derivative of 1 nM, polarization of Th2 cells was induced using PMA and A23187. After two days of culture, the cells were centrifuged and the culture medium was taken to perform IL-5 ELISA. IL-5 ELISA was performed according to the test method of the kit manufacturer. As a result, an inhibitory ratio of IL-5 expression was derived with Th0 cells, which did not induce Th2 differentiation, as 100% inhibition and with Th2 cells, which were not treated with the novel derivative, as a control for 0% inhibition.

Experimental Example 3. Comparative Experiment for Inhibition of Novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one Derivatives Against IL-4 Secretion

In order to confirm the inhibitory effect of the novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives against IL-4 expression, the RBL-2H3 cell line was used to measure the ability for inhibiting IL-4 secretion. The RBL-2H3 cell line was purchased from the American Type Culture Collection (ATCC #CRL-2256). The cells were diluted at a concentration of 1×106 cells/ml in RPMI medium containing 15% fetal bovine serum (FBS) and antibiotics (penicillin at 100 U/mL, streptomycin at 100 μg/mL), distributed at 200 μl/well in a 48 well plate, and cultured in a 37° C., 5% CO2 incubator for 24 hours. In 24 hours later, the cells were pre-treated one hour before with a test drug and AS1517499 (STAT6 inhibitor) as a control drug, and treated with 1 uM of A23187 for six hours to induce an immune response, after which a group not containing the drug was used as a control. In order to measure a secretion level of cytokine IL-4, the medium was collected from the well plate and centrifuged at 125×g for five minutes to remove a residue, and 100 μl of the medium was used to measure an amount of IL-4 secreted from the cells by using IL-4 enzyme-linked immunosorbent assay (ELISA, Komabiotech). A degree of inhibition of cell secretion by the drug was calculated using [Equation 1] below.

The isolated splenocytes were diluted at a concentration of 5×106 cells/mL in RPMI medium containing 10% fetal bovine serum (FBS) and antibiotics (penicillin at 100 U/mL, streptomycin at 100 μg/mL), distributed at 500 μl/well in a 24 well plate, and cultured in a 37° C., 5% CO2 incubator for 48 hours. When splenocytes were distributed, an immune reaction was induced by treating with 5 μg/mL of Concanavalin A, and at this time, the splenocytes were treated with the materials selected in Experimental Example 3 at a concentration of 1 uM. First, in order to measure Th2 cytokines, the medium was collected from the 24-well plate, and only the supernatant was separated through centrifugation at 800×g for five minutes, after which 100 μl of the supernatant per well was used in an enzyme-linked immunosorbent assay (ELISA, Komabiotech) experiment so as to measure a degree of secretion of Th2 cytokines IL-4 and IL-5. A degree of inhibition against secretion of cytokines by the test material was calculated using [Equation 2] below, and the measurement results are shown in Table 7.

As confirmed in Table 7, the mouse splenocytes were treated with the derivatives at a concentration of 1 uM, and thus it was confirmed that IL-4 and IL-5 secretion are remarkably inhibited in most of the experimental groups compared to the normal group. In particular, it was observed that the secretion of the cytokine IL-4 is relatively low compared to IL-5. From the above results, it is considered that the novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives have a medicinal effect on respiratory diseases such as asthma as well as an anti-inflammatory effect through the inhibition of actual cytokines.


Experimental Example 8. Comparative Experiment for Inhibitory Effect of Novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one Derivatives Against Asthma in Balb/c Mouse Asthma Model

The novel 6,7-dimethoxynaphtho[2,3-c]furan-1(3H)-one derivatives were used to measure changes in several indicators related to asthma, a type of respiratory disease, in the Balb/c mouse asthma model. In detail, five-week-old Balb/c mice were purchased and acclimated for one week, after which the mice were sensitized systemically by intraperitoneal injection with 0.1% ovalbumin (OVA 1 mg/mL, Al(OH)3 20 mg/mL) at 100 μl/mouse on days 0 and 14 from a week after the acclimation. From a week (day 21) after a final systemic sensitization, the compound of Example 73 was orally administered everyday at 10 mg/kg to mice for ten days, and dexamethasone was intraperitoneally administered at 1 mg/kg as a positive control group. In one hour later, 0.2% ovalbumin solution was sprayed with a nebulizer (PARIBoy SX, GmbH, Germany) so as to be inhaled for one hour. In five hours after the final sensitization (day 30), an autopsy was performed, and 1 mL of phosphate buffer solution was flowed through a tracheotomy to collect a bronchoalveolar lavage fluid (BALF). The collected BALF was centrifuged at 3000 rpm for ten minutes, and the supernatant was used to measure bioactive materials (IL-4, IL-5), and pellets were used to measure the number of inflammatory cells. In addition, an IgE concentration in the isolated BALF was measured using IgE enzyme-linked immunosorbent assay (ELISA, Komabiotech), and IL-4 and IL-5 were measured using their respective enzyme-linked immunosorbent assay (ELISA, IL-4: Enzo #ADI-900-043, IL-5: R&D system #M5000).


The results are shown in Table 8 and FIG. 22, and each secretion inhibitory activity was calculated in the same manner as in [Equation 2] of Experimental Example 4.

In addition, the BALF pellets were re-dissolved by adding 0.5 mL of phosphate buffer solution, and then 0.1 mL for each thereof was added to a 96-well plate and centrifuged at 800 rpm for five minutes to attach cells to the bottom (three wells per sample). Then, the cells were stained with Diff Quik staining solution (Sysmex) and the number of cells was measured with a flow cytometer.


The results were shown in FIG. 21, the SPSS program was used for statistical processing, the Levene test was performed for equal-variance test, and the significance test was performed through one-way ANOVA.


As can be seen in Table 8, FIGS. 22 and 21, the compound of Example 73 reduced Th2 cytokines IL-4 and IL-5 as well as IgE in the BALF. In addition, it was observed that inflammatory cells are reduced as a whole and, in particular, the number of eosinophils highly associated with type 2 asthma is significantly reduced. From these results, it was confirmed that the compound of Example 73 has an excellent allergy inhibitory effect and is a material capable of effectively treating respiratory diseases such as asthma.
