`Immunosuppressive agents are widely used as a treatment for autoimmune diseases such as rheumatoid
`arthritis, nephritis, osteoarthritis
`such
`and systemic lupus erythematosus,
`
`chronic
`inflammatory
`diseases
`
`tory bowel disease, and allergic diseases
`such
`as
`asthma
`and
`
`dermatitis. has led to an increase Progress
`in the number of tissue and organ transplantations performed each year. In such a situation of modern medicine, having
`as much control as possible
`over
`the
`rejection

`following a key to successful transplantation transplantation.

`is
`
`Immu

`
`significant end.
`role
`to
`this
`a
`[0003] Among immunosuppressors
`commonly used in organ transplantation are antimetabolites, such as azathio-
`prine and mycophenolate mofetil, calcineurin inhibitors, such as cyclosporin A and tacrolimus, and corticosteroid, such
`as prednisolone. Some of these drugs are not effective enough while others require continuous monitoring of the blood
`drug level to avoid renal failure and other serious side effects. Thus,
`none of conventional
`
`immunosuppressive agents
`are satisfactory
`in view of efficacy and potential
`side
`effects.
`[0004] Multiple drug combined-therapy, in which different immunosuppressive
`drugs with different mechanisms of
`action are used, is becoming increasingly common with the aims of alleviating the side effects of the drugs and achieving
`sufficient immunosuppressive
`effects.
`Also,
`
`development of new types of immunosuppressive agents
`that
`have
`pletely different mechanisms
`of action is sought.

`
`to such demands, the present

`DISCLOSURE OF THE
`
`INVENTION
`
`[0007] Accordingly, it is an objective of the present invention to provide a diaryl ether derivative that exhibits significant
`immunosuppressive effects with
`little
`side
`effects.
`[0008]
`from
`
`In the course of studies on immunosuppressive agents that have different mechanisms of action
`tabolites and calcineurin inhibitors, the present inventors discovered
`that novel diaryl ether derivatives that have a
`different structure
`from
`conventional
`
`immunosuppressors exhibit strong
`immunosuppressive
`effects.
`Specifically,
`compounds aresuch that one of the aryl groups includes, at its para-position, acarbon chain with an aminopropanediol
`group and the other aryl
`
`group includes a substituent at
`its meta-position.
`
`This led the present discovery inventors
`
`
`to
`devise the present
`invention.
`[0009] The present invention
`as
`containing
`agent
`immunosuppressive
`is an
`thus
`a diaryl ether derivative, a pharmaceutically acceptable salt and hydrate thereof, the diaryl ether derivative represented
