  作为有效醛糖还原酶抑制剂 (ARI) 的新 piplartine 类似物的合成和生物学评价

  摘要：

  作为我们致力于从天然来源开发抗糖尿病药物的继续努力，从胡椒中分离出了哌拉汀，并发现它可以抑制重组人 ALR2，IC 50为 160 μM。为了提高功效，通过修饰这种天然产物先导物的苯乙烯基/芳香族和杂环官能团，合成了一系列类似物。对所有衍生物的ALR2抑制活性进行了测试，结果表明，哌拉汀与吲哚衍生物迈克尔加成制备的加合物3c 、 3e和2j表现出有效的ARI活性，而其他化合物则表现出不同程度的抑制作用。这些活性化合物还能够防止山梨醇在人红细胞中积聚。

  Activation of polyol pathway due to increased aldose reductase (ALR2) activity is one of the several mechanisms that have been implicated in the development of various complications of diabetes such nephropathy, neuropathy, retinopathy and cataract. Hence, inhibition of ALR2 has been considered as an effective means to prevent and treat the diabetic complications. We have shown that piplartine isolated from Piper species (Piper chaba) inhibits ALR2 activity. Use of compounds of general formula A isolated from medicinal plant Piper chaba having (Aldose reductase) ALR2 inhibitory activity and serves as a lead molecule to synthesize novel ALR2 inhibitors, wherein Ri=Hyrogen, Methyl or Benzyl; R2=Methyl or Phenyl; R3=Nitro, Fluro, Bromo, Iodo, Methyl or Methoxy; R4 is selected from wherein the representative compounds comprising synthesis of Michael adduct from naturally isolated piplartine with different substituted indoles, by using catalytic amount of molecular iodine, under selective solvent 1,2-Dichloroethane are: Mono Michael adduct 2a-c, 2f-k Di Michael adduct 3a-3k

  As a continuation of our efforts directed towards the development of anti-diabetic agents from natural sources, piplartine was isolated from Piper chaba, and was found to inhibit recombinant human ALR2 with an IC50 of 160 μM. To improve the efficacy, a series of analogues have been synthesized by modification of the styryl/aromatic and heterocyclic ring functionalities of this natural product lead
