摘要
以吲哚美辛(1)为原料先经酯化反应和Knoevenagel缩合,再与可溶性淀粉连接,合成了侧链含有阿魏酸的高分子载体药物(4),该化合物未见文献报道.用比浊法和放免法测定了(4)体外对兔血小板聚集以及对TXB2,6KetoPGF1α含量的影响.化合物(4)240μmol·L-1对AA诱导的兔血小板聚集的抑制率为396%,对TXB2释放的抑制率为287%.与吲哚美辛(1)或阿魏酸比较,阿魏酸衍生物高分子载体药物(4)显示有抑制兔体外血小板聚集和抑制TXB2,6KetoPGF1α释放的作用,呈现明显的药物协同作用.
The polymeric drug(FAIS) which contains ferulic acid(FA) was synthesized from indomethacin via esterfication and the Knoevenagel condensation,and then conjunction with soluble starch(S).This new compound was obtained for the first time.The results of preliminary pharmacological tests showed that the FAIS could inhibit the rabbit platelet aggregation induced by arachidonic acid(AA) and release of TXB2 and 6KetoPGF1.Its activity was stronger than that of FA and indomethacin.It was in evidence to express the good synergic effect.
