An angiogenesis promoter containing a compound of the following formula (I)
wherein R1 is acyl, R2 is alkyl, R3 and R4 are the same or different and each is hydrogen atom or hydroxy protecting group and R5 is alkyl, as an active ingredient. This compound itself not only has an angiogenesis promoting effect but also potentiates the angiogenic effect by a drug (e.g., b-FGF) having such effect. Therefore, it can express the angiogenesis promoting effect more effectively in the ischemic tissues and the site under different disease state, where b-FGF has locally increased.
一种含有下式(I)化合物的血管生成
促进剂
其中 R1 为酰基,R2 为烷基,R3 和 R4 相同或不同,且各自为氢原子或羟基保护基团,R5 为烷基。这种化合物本身不仅具有促进血管生成的作用,而且还能增强具有这种作用的药物(如 b-FGF)的血管生成作用。因此,它能在缺血组织和不同疾病状态下 b-FGF 局部增高的部位更有效地发挥促进血管生成的作用。
