The present invention relates to prevention or treatment of a brain edema, an intracranial hemorrhage and a cerebral infarction by use of a compoundof the formula:
wherein A is halogen, -X-R³ in which X is O, S, NH or NHNH, and R³ is H, acyl, a hydrocarbon group or an aromatic heterocyclic group, or -Y=R⁴ in which Y is N or NHN, and R⁴ is a divalent hydrocarbon group, and R¹ is H, halogen, a hydrocarbon group, a heterocyclic group or -Z-R⁵ in which Z is O, S or NH, and R⁵ is H, a hydrocarbon group or an aromatic heterocyclic group;
R² is H, halogen, a hydrocarbon group or a heterocyclic group;
B is -W-R⁶ in which W is CH₂, CO or CS, and R⁶ is OH, alkoxy, acyloxy, alkylsulfinyl, alkylsulfonyl, phosphoric acid or amino, or B together with E form a cyclic phosphoric ester; and
D and E are H, amino, azido, halogen or OH, or a pharmaceutically acceptable salt thereof, for the manufacture of a medicament for inhibiting a vascular permeability enhancer.
本发明涉及利用式中化合物预防或治疗脑水肿、颅内出血和脑梗塞:
其中 A 是卤素,-X-R³ 其中 X 是 O、S、NH 或 NHNH,R³ 是 H、酰基、烃基或芳香杂环基,或 -Y=R⁴ 其中 Y 是 N 或 NHN,R⁴ 是二价烃基、和 R¹ 是 H、卤素、烃基、杂环基或-Z-R⁵,其中 Z 是 O、S 或 NH,而 R⁵ 是 H、烃基或芳香杂环基;
R² 是 H、卤素、烃基或杂环基;
B 是-W-R⁶,其中 W 是 CH₂、CO 或 CS,R⁶ 是 OH、烷氧基、酰氧基、烷基亚磺酰基、烷基磺酰基、磷酸或氨基,或者 B 与 E 一起形成环状磷酸酯;以及
D 和 E 是 H、氨基、叠氮、卤素或 OH,或其药学上可接受的盐,用于制造抑制血管渗透性增强剂的药物。
