Definitions
- the present invention relates to a pyridine derivative, and more particularly, to a novel pyridine derivative or a salt thereof having an excellent cytokine production inhibitory action and high safety, and a medicament containing the same as an active ingredient.
- the immune system which is a defense mechanism against exogenous and endogenous foreign substances in the living body, consists of a myeloid cell group represented by macrophages and neutrophils, and lymphocytes composed of T cells and B cells. It is composed of cells of the system. These cell groups not only function independently, but also maintain their homeostasis through direct contact between cells or interaction through soluble factors collectively called cytokines. The mechanism is sophisticated, and subtle disruptions in balance can lead to serious pathology.
- Collagen disease systemic lupus erythematosus, and various allergic diseases are said to develop as a result of disruption of the regulatory mechanism of such immune cells, production of antibodies against self, or induction of an excessive immune response.
- AIDS immunodeficiency syndrome group
- T-cell HIV infection acquired immunodeficiency syndrome group
- disruption of the immune system can contribute to diabetes, chronic diseases caused by viruses, and progression of cancer.
- cytostatic in production inhibitors such as cyclosporine and FK506, which are already known as inhibitors of rejection during organ transplantation, have been used for the treatment of these diseases, and autoimmune diseases such as allergic disease, atopy and rheumatism have been used.
- Anti-inflammatory steroids which have an effect of inhibiting the production of site power in, are also used for bronchial asthma and the like, and some therapeutic effects have been obtained.
- the immune system is indispensable for the host's temporary defense mechanism, and that infectious diseases can be extremely easily acquired in an immunodeficient state due to administration of immunosuppressants or anticancer drugs.
- an object of the present invention is to provide a powerful, highly specific and safe immune function regulator capable of suppressing the production of specific cytokines produced in excess in various immune diseases. Disclosure of the invention
- the present inventors have synthesized a number of compounds and studied their cytokine production inhibitory action.As a result, a novel pyridine derivative represented by the following general formula (1) and a salt thereof were obtained.
- the present inventors have found that the present invention strongly suppresses the production of interleukin-4 and IL-5, has high safety and has an excellent immune function regulating action, and has completed the present invention.
- IL-4 and 1L-5 are cytokines mainly produced by Th2 helper T cells, and one or four are involved in B cell differentiation and the like, and are deeply involved in ⁇ gE-mediated allergic reactions.
- IL-5 is involved in B cell proliferation, IgA production, and eosinophil activation.
- the compound of the present invention strongly suppresses the production of -4 and IL-5 in the cytokine network, the effect of enhancing or suppressing the production of other cytokines is expected.
- R 'and R 2 are the same or different and each represents a hydrogen atom, an alkyl group, Hidorokin Alkyl group, an alkoxyalkyl group which may have a substituent, Karubokishiaru kill group, alkoxycarbonylalkyl group, which may have a substituent Araruki group, indicates Fuenashiru group or Ashiru group, R 3 is an alkyl group, a substituted A phenyl group, a heteroaryl group or a compound represented by the following formula (2)
- Y represents a methylene group or an oxygen atom
- m represents an integer of 1-2
- n represents an integer of 1-3
- m + n represents an integer of 3-5.
- X represents a cyclic amino group represented by Represents an oxygen atom or a combination of a hydroxyl group and a hydrogen atom.
- the present invention also provides a drug containing the pyridine derivative represented by the above general formula (1) or a salt thereof as an active ingredient, particularly, a cytokine production inhibitor and an immune function regulator.
- the present invention also provides the use of the pyridine derivative represented by the above general formula (1) or a salt thereof as a medicament, particularly as a cytokine inhibitor or an immune function regulator.
- the present invention also provides a method for treating a disease based on cytokine production or a disease having an abnormal immune function, which comprises administering to a patient an effective amount of the pyridine derivative represented by the above general formula (1) or a salt thereof. Is what you do.
- the alkyl group represented by R ′ and R 2 includes a linear, branched or cyclic alkyl group, and includes a linear or branched alkyl group.
- examples thereof include those having 1 to 8 carbon atoms, such as a methyl group, an ethyl group, an ⁇ -propyl group, an isopropyl group, an n-butyl group, an isobutyl group, an n-pentyl group, and an n-hexyl group.
- Examples thereof include those having 3 to 8 carbon atoms, for example, cyclopropyl group, cyclobutyl group, cyclopentyl group, cyclohexyl group, cycloheptyl group and the like.
- Hydroxyalkyl groups having 1 to 8 carbon atoms, such as hydro Examples include a xymethyl group, a hydroxyethyl group, a hydroxydipropyl group, a hydroxybutyl group, a hydroxypentyl group, a hydroquinhexyl group, and a hydroquinheptyl group.
