The invention provides a compound of the formula (1 ): or a salt, solvate, N-oxide or tautomer thereof; wherein either R1 is R1a and R2 is R2a; or R1 is R1b and R2 is R2b; provided that in each case at least one of R1 and R2 is other than hydrogen; R1a and R2a are the same or different and each is selected from hydrogen, C1-4 alkyl, C2-4 alkenyl and C2-4 alkynyl wherein the C1-4 alkyl is optionally substituted by C1-2 alkoxy; R1b and R2b are the same or different and are selected from hydrogen, C(O)NR4R5, C(O)R6 and C(O)OR6 where R6 is C1-4 alkyl, R4 and R5 are both C1-4 alkyl, or NR4R5 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 C1-4 alkyl groups and/or one or two oxo groups; and R3 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.
该发明提供了一个化合物,其化学式为(1):或其盐、溶剂合物、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;但在每种情况下,R1和R2中至少有一个不是氢;R1a和R2a相同或不同,每个都选自氢、C1-4烷基、C2-4烯基和C2-4炔基,其中C1-4烷基可选择地被C1-2烷氧基取代;R1b和R2b相同或不同,选自氢、C(O)NR4R5、C(O)R6和C(O)OR6,其中R6是C1-4烷基,R4和R5都是C1-4烷基,或NR4R5形成一个含有第二杂原子环成员O、N或S和氮和硫的氧化形式的4到7成员饱和杂环,该杂环可选择地被一个或两个C1-4烷基基团和/或一个或两个氧基团取代;R3是一个基团(D):其中星号表示与异吲哚啉环的连接点;但不包括乙酸5-乙氧基-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]-苯基酯。
