The use of compounds of the formula (I):
or pharmaceutically acceptable salts or bio-precursors thereof; wherein
R' is hydrogen, C1-4 alkyl, C2-4 alkenyl, a group -BX(R5)n, or-BZBX(R5) wherein Z and X (when n = 1) are the same or different and each is-O, -S(O)q or-NR6, wherein q is 0,1 or 2 and R6 is hydrogen or C1-4 alkyl or, when n = O, X is halogen;
R5 is hydrogen, C1-12 aralkyl or C1-10 alkyl;
B is C1-5 alkanyl;
R2 is hydrogen, C1-4 alkyl, C2-4 alkenyl, or a group BOR7 wherein R7 is hydrogen or C1-6 alkyl;
or R1 and R2 together with the carbon atoms in the pteridine ring structure to which they are attached form a C5-7 cycloalkyl ring;
provided that at least one of R', R2, R3, and R4 is hydrogen and that one of R', R2, and R3, R4 represents gem di-substitution unless R' represents CH2OR7 in which case R2, R3 and R4 can all be hydrogen, in the treatment of neurological disorder is disclosed. Pharmaceutical compositions containing compounds of the formula (I), novel compounds and processes for preparing the novel compounds are also disclosed.
使用式(I)化合物:
或其药学上可接受的盐或生物前体;其中
R'是氢、C1-4 烷基、C2-4 烯基、基团 -BX(R5)n,或-BZBX(R5),其中 Z 和 X(当 n = 1 时)相同或不同,且各自是-O、-S(O)q 或-NR6,其中 q 是 0、1 或 2,R6 是氢或 C1-4 烷基,或当 n = O 时,X 是卤素;
R5 是氢、C1-12 芳烷基或 C1-10 烷基;
B 是 C1-5 烷基;
R2 是氢、C1-4 烷基、C2-4 烯基或基团 BOR7,其中 R7 是氢或 C1-6 烷基;
或 R1 和 R2 与它们所连接的蝶啶环结构中的碳原子一起形成一个 C5-7 环烷基环;
只要 R'、R2、R3 和 R4 中至少有一个是氢,并且 R'、R2 和 R3、R4 中有一个代表 gem 二取代基,除非 R'代表 CH2OR7,在这种情况下,R2、R3 和 R4 可以都是氢,本发明就可以用于治疗神经紊乱。还公开了含有式(I)化合物的药物组合物、新型化合物和制备新型化合物的工艺。
