The invention provides a compound of the formula (1):
or a salt, solvate, N-oxide or tautomer thereof;
wherein either R
1
is R
1a
and R
2
is R
2a
; or R
1
is R
1b
and R
2
is R
2b
; provided that in each case at least one of R
1
and R
2
is other than hydrogen;
R
1a
and R
2a
are the same or different and each is selected from hydrogen, C
1-4
alkyl, C
2-4
alkenyl and C
2-4
alkynyl wherein the C
1-4
alkyl is optionally substituted by C
1-2
alkoxy;
R
1b
and R
2b
are the same or different and are selected from hydrogen, C(O)NR
4
R
5
, C(O)R
6
and C(O)OR
6
where R
6
is C
1-4
alkyl, R
4
and R
5
are both C
1-4
alkyl, or NR
4
R
5
forms a 4 to 7 membered saturated heterocyclic ring optionally containing a second heteroatom ring member selected from O, N or S and oxidised forms of N and S, the heterocyclic ring being optionally substituted by one or two C
1-4
alkyl groups and/or one or two oxo groups; and
R
3
is a group D:
wherein the asterisk denotes the point of attachment to the isoindoline ring; but excluding acetic acid 5-acetoxy-4-isopropyl-2-[5-(4-methyl-piperazin-
1
-ylmethyl)-1,3-dihydro-isoindole-2-carbonyl]-phenyl ester.
本发明提供了式(1)的化合物:或其盐,溶剂化物,N-氧化物或互变异构体;其中,R1是R1a且R2是R2a;或R1是R1b且R2是R2b;但每种情况下至少有一个R1和R2不是氢;R1a和R2a相同或不同,且每个都选择自氢,C1-4烷基,C2-4烯基和C2-4炔基,其中C1-4烷基可选地被C1-2烷氧基取代;R1b和R2b相同或不同,选择自氢,C(O)NR4R5,C(O)R6和C(O)OR6,其中R6是C1-4烷基,R4和R5均为C1-4烷基,或NR4R5形成4到7个成员的饱和杂环环,可选择包含第二个杂原子环成员,所选为O,N或S和N和S的氧化形式,杂环环可选择由一个或两个C1-4烷基基团和/或一个或两个氧基基团取代;以及R3是D基团:其中星号表示连接到异吲哚啉环的位置;但不包括乙酸5-乙酰氧基-4-异丙基-2-[5-(4-甲基哌嗪-1-基甲基)-1,3-二氢异吲哚-2-羰基]-苯酯。
