Pharmaceutical composition for inhibiting immune response through inducing differentiation into regulator T cells and promoting proliferation of regulator T cells
The present invention relates to new medical use of (tetrahydropyran-4-yl)-[2-phenyl-5-(1,1-dioxo-thiomorpholine-4-yl)methyl-1H-indol-7-yl]amine, and more particularly, to a pharmaceutical composition containing the compound as an active ingredient, which is used for inhibiting an immune response, and/or for inducing differentiation into regulator T cells from undifferentiated T cells and/or promoting proliferation of regulator T cells.
1. A method for suppressing immune response, comprising
administering (tetrahydropyran-4-yl)-[2-phenyl-5-(1,1-dioxo-thiomorpholin-4-yl)methyl-1H-indol-7-yl]amine, a pharmaceutically acceptable salt or isomer thereof to a subject in need thereof.
2. The method according to claim 1 , which is for suppressing immune rejection reaction to transplantation of skin, blood, cornea, liver, lung, intestine, pancreas, heart, kidney, bone marrow, stem cell or precursor cell.
3. The method according to claim 1 , which is for the treatment and prevention of graft-versus-host disease, allergic disease, autoimmune disease or inflammatory disease.
4. A method for inducing differentiation into regulatory T cell, which comprises a step of
treating immature T cell with a composition comprising (tetrahydropyran-4-yl)-[2-phenyl-5-(1,1-dioxo-thiomorpholin-4-yl)methyl-1H-indol-7-yl]amine, a pharmaceutically acceptable salt or isomer thereof ex vivo.
5. The method according to claim 4 , wherein the composition further comprises an anti-CD3 antibody, an anti-CD28 antibody and TGF-beta.
6. The method according to claim 4 , wherein the composition further comprises retinoic acid (RA) or retinal.
7. The method according to claim 4 , wherein the regulatory T cell has the phenotype of CD4 + , CD25 + and Foxp3 + .
8. A method for promoting proliferation of regulatory T cell, which comprises a step of
treating immature T cell with a composition comprising (tetrahydropyran-4-yl)-[2-phenyl-5-(1,1-dioxo-thiomorpholin-4-yl)methyl-1H-indol-7-yl]amine, a pharmaceutically acceptable salt or isomer thereof ex vivo.
9. The method according to claim 8 , wherein the composition further comprises retinoic acid (RA) or retinal.
10. A method for obtaining regulatory T cell via inducing differentiation and promoting proliferation of regulatory T cell, which comprises a step of
treating immature T cell with a composition comprising (tetrahydropyran-4-yl)-[2-phenyl-5-(1,1-dioxo-thiomorpholin-4-yl)methyl-1H-indol-7-yl]amine, a pharmaceutically acceptable salt or isomer thereof ex vivo.
