Inhibitory effects of synthetic 2'-hydroxychalcone derivatives on rat lens aldose reductase (RLAR) and on platelet aggregation were investigated for the prevention or the treatment of chronic diabetic complications. 5'-chloro-4, 2'-dihydroxychalcone (8) and 5'-chloro-3, 2'-dihydroxychalcone (27) exhbited a potent inhibitory effect on rat platelet aggregation induced by ADP (IC50=0.10 and 0.06 mg/ml, respectively) and collagen (IC50=44 and 16 μg/ml, respectively) but showed relatively weak inhibitory activities on RLAR.
合成的2'-羟基查尔酮衍生物对大鼠晶状体醇糖还原酶(RLAR)及血小板聚集的抑制作用被研究,以防止或治疗慢性糖尿病并发症。5'-氯-4, 2'-二羟基查尔酮(8)和5'-氯-3, 2'-二羟基查尔酮(27)对ADP诱导的大鼠血小板聚集表现出强效抑制作用(IC50分别为0.10和0.06 mg/ml),对胶原蛋白的抑制作用也较强(IC50分别为44和16 μg/ml),但对RLAR的抑制活性相对较弱。
