Abstract:
The present invention relates to a substituted purine derivative of formula (1) wherein R 1  is alkoxy or the like, R 2  is alkyl or the like, Ring Q 1  is aryl or the like, W 1  is alkylene or the like, Ring Q 2  is aromatic carbocyclyl or the like, n is 1-4, R 3  is hydrogen atom or the like, X 1  is single bond or the like, W 2  is alkylene or the like, and R 4  is hydrogen atom or the like, or a pharmaceutically acceptable salt thereof, which has a potent inhibitory effect against TLR7, and thereby is useful for treating autoimmune disease.

Claim (Index 17):
The compound of  claim 1  or a pharmaceutically acceptable salt thereof, wherein\n R 4  is \n (1) hydrogen atom, \n (2) \u2014OR b  wherein R b  is hydrogen atom, C 1-6  alkyl, or C 1-6  alkylsulfonyl, \n (3) \u2014NR c R d  wherein R c  and R d  are independently hydrogen atom or C 1-6  alkyl which may be substituted with 1-3 the same or different halogen atoms, \n (4) 4- to 10-membered saturated heterocyclyl which may be substituted with 1-4 the same or different substituents selected from the group consisting of \n (a) halogen atom, \n (b) hydroxy, \n (c) cyano, \n (d) C 1-6  alkyl which may be substituted with 1-3 the same or different substituents selected from the group consisting of halogen atom, hydroxy, and C 1-6  alkoxy, \n (e) C 1-6  alkoxy which may be substituted with 1-3 the same or different substituents selected from the group consisting of halogen atom, hydroxy, and C 1-6  alkoxy, \n (f) C 3-7  cycloalkyl, \n (g) C 1-6  alkylcarbonyl which may be substituted with 1-3 the same or different substituents selected from the group consisting of halogen atom, hydroxy, amino (which may be substituted with 1-2 the same or different C 1-6  alkyl), and C 1-6  alkoxy, \n (h) C 1-6  alkoxycarbonyl, \n (i) 4- to 7-membered saturated heterocyclyl which may be substituted with 1-4 the same or different substituents selected from the group consisting of halogen atom, C 1-6  alkyl, and C 1-6  alkoxy, and \n (j) oxo, or \n (5) 5- to 10-membered heteroaryl which may be substituted with 1-4 the same or different substituents selected from the group consisting of halogen atom, C 1i-6  alkyl, and C 1-6  alkoxy.
