  SENP1抑制剂熊果酸衍生物的发现及放射增敏研究

  摘要：

  SUMO化和去SUMO化在DNA损伤反应和放疗抵抗的形成中发挥着重要作用。 SENP1是催化去SUMO化修饰的主要特异性异肽酶。抑制 SENP1 会上调癌细胞的放射敏感性，使其成为放射增敏的有希望的靶标。在此，基于熊果酸（UA）的结构，总共设计并合成了53个五环三萜衍生物作为SENP1抑制剂。十种衍生物表现出比UA更好的SENP1抑制活性，并讨论了初步的构效关系。大多数UA衍生物的细胞毒性较低，其中化合物36的放射增敏活性最好， SER值为1.45。这是第一项开发小分子 SENP1 抑制剂作为放射增敏剂的研究。

  From CH2Cl2 and MeOH extracts of the stems of Cynomorium songaricum RUPR. (Cynomoriaceae), ursolic acid and its hydrogen malonate were isolated as inhibitors of human immunodeficiency virus type 1 (HIV-1) protease, with 50% inhibitory concentrations (IC50) of 8 and 6 μM, respectively. Amongst various synthesized dicarboxylic acid hemiesters of related triterpenes, inhibitory activity tended to increase in the order of oxalyl, malonyl, succinyl and glutaryl hemiesters, for triterpenes such as ursolic acid, oleanolic acid and betulinic acid. The most potent inhibition was observed for the glutaryl hemiesters, with an IC50 of 4 μM.From the water extract of the stems of C. songaricum, flavan-3-ol polymers, consisting of epicatechin as their extender flavan units, were also found to be potent inhibitory principles against HIV-1 protease.

  Plants produce a wide variety of cyclic triterpenes, such as sterols and triterpenoids, which are the major products of the mevalonate (MVA) pathway. It is important to understand the physiological functions of HMG-CoA reductase (HMGR) because HMGR is the rate-limiting enzyme in the MVA pathway. We have previously isolated Arabidopsis mutants in HMG1 and HMG2. Although the biochemical function of HMGR2 has been thought to be almost equal to that of HMGR1, based on similarities in their sequences, the phenotypes of mutants in these genes are quite different. Whereas hmg2 shows no abnormal phenotype under normal growth conditions, hmg1 shows pleiotropic phenotypes, including dwarfing, early senescence, and male sterility. We previously postulated that the 50% decrease in the sterol content of hmg1, as compared to that in the wild type, was a cause of these phenotypes,1) but comprehensive triterpene profiles of these mutants had not yet been determined. Here, we present the triterpene profiles of hmg1 and hmg2. In contrast to hmg1, hmg2 showed a sterol content 15% lower than that of the wild type. A precise triterpenoid quantification using synthesized deuterated compounds of β-amyrin (1), α-amyrin (2), and lupeol (3) showed that the levels of triterpenoids in hmg1 and hmg2 were 65% and 25% lower than in the wild type (WT), respectively. These results demonstrate that HMGR2 as well as HMGR1 is responsible for the biosynthesis of triterpenes in spite of the lack of visible phenotypes in hmg2.

  植物产生多种环状三萜，如固醇和三萜类化合物，这些是梅瓦龙酸（MVA）途径的主要产物。了解HMG-CoA还原酶（HMGR）的生理功能非常重要，因为HMGR是MVA途径中的限速酶。我们之前已经分离出阿拉伯芥中HMG1和HMG2的突变体。虽然基于它们序列的相似性，HMGR2的生化功能被认为几乎与HMGR1相同，但这些基因突变体的表型却大相径庭。HMG2在正常生长条件下没有显示出异常表型，而HMG1则表现出多重表型，包括矮小、早衰和雄性不育。我们之前推测，HMG1的固醇含量比野生型降低50%是这些表型的原因之一，但这些突变体的全面三萜谱尚未确定。在这里，我们呈现HMG1和HMG2的三萜谱。与HMG1相比，HMG2的固醇含量比野生型低15%。使用合成的重氢化合物β-氨瑞烯（1）、α-氨瑞烯（2）和露蓉醇（3）进行的精确三萜类化合物定量显示，HMG1和HMG2中的三萜类化合物水平分别比野生型低65%和25%。这些结果表明，虽然HMG2缺乏明显的表型，但HMGR2和HMGR1均负责三萜的生物合成。
