  摘要：

  桦木酸衍生物IC9564抑制人免疫缺陷病毒（HIV）-1的进入。在一系列IC9564衍生物中，有5种和20种是最有希望的抗HIV感染化合物，其EC（50）值分别为0.33和0.46 microM。两种化合物抑制合胞体形成与EC（50）值分别为0.40和0.33 microM。两种测定法中可比较的EC（50）值表明，这些化合物是融合抑制剂。结构-活性关系数据还表明，可以消除IC9564中的双键，并且可以在保持抗HIV活性的同时用L-亮氨酸取代他汀类药物部分。

  Synthesis and biological evaluation of a new derivative of bevirimat that targets the Gag CA-SP1 cleavage site

  摘要：

  Bevirimat (2), the first-in-class HIV-1 maturation inhibitor, shows a low efficacy due essentially to the natural polymorphism of its target, the CA-SP1 junction. Moreover, its low hydrosolubility makes it difficult to study its interaction with the CA-SP1 junction. We have synthesized new derivatives of bevirimat by adding different hydrophilic substituents at the C-28 position to improve their hydrosolubility and perform the structural study of a complex by NMR. Synthesis of the new derivatives, the effect of substituents at the C-28 position and their hydrosolubility are discussed. The ability of these molecules to inhibit viral infection and their cytotoxicity is assessed. Compared to the well-known bevirimat (2), one of our compounds (16) shows a higher hydrosolubility associated with a 2.5 fold increase in activity, a higher selectivity index and a better antiviral profile. Moreover, for the first time a direct interaction between a derivative of bevirimat (16) and the domain CA-SP1 NC is shown by NMR. Information from this study should allow us to decipher the mechanism by which bevirimat inhibits HIV-1 maturation and how the natural polymorphism of the spacer peptide SP1 triggers resistance to inhibitors.

  indicating the activation of the intrinsic apoptosis pathway. Furthermore, 48 dramatically induced the generation of reactive oxygen species (ROS) in HL-60 cells, and the corresponding effect could be reversed using the ROS scavenger N-acetylcysteine. Collectively, these results suggest that the novel pentacyclic triterpenoid derivatives trigger the intrinsic apoptotic pathways via the ROS-mediated activation

  桦木酸 (BA) 和齐墩果酸 (OA) 是植物衍生的结合物，存在于各种药用植物中，已成为潜在的抗肿瘤药物。在此，通过与全O-甲基化-β-环糊精 (PM-β-CD)缀合合成了一系列新型 BA 和 OA 衍生物，并评估了它们对一组三种人类癌细胞系的抗癌特性。观察到两种 OA-PM-β-CD 缀合物（48和50）是针对三种细胞系（MCF-7、BGC-823 和 HL-60）的最有效缀合物，具有 15 至 20 倍IC 50值降低（IC 50: 6.06–8.47 μM) 与其亲本偶联物 (OA) 相比。膜联蛋白 V-FITC/碘化丙啶染色和蛋白质印迹分析表明，两种结合物均能诱导 HL-60 细胞凋亡。此外，在代表性缀合物48处理的 HL-60 细胞中，观察到线粒体膜电位降低和随后细胞色素c释放到胞质溶胶中，表明内在凋亡途径的激活。此外，48显着诱导 HL-60 细胞中活性氧 (ROS) 的产生，并且使用

  A novel series of omega-aminoalkanoic acid derivatives of betulinic acid were synthesized and evaluated for their activity against human immunodeficiency virus (HIV). The anti-HIV-1 activity of several members of this new series was found to be in the nanomolar range in CEM 4 and MT-4 cell cultures. The optimization of the omega-aminoalkanoic acid side chain is described. The presence of an amide function within the side chain was found important for optimal activity. RPR 103611 (14g), a statine derivative, was found to be inactive against HIV-1 protease, reverse transcriptase, and integrase as well as on gp120/CD4 binding. ''Time of addition'' experiments suggested interaction with an early step of HIV-1 replication. As syncytium formation, but not virus-cell binding, seems to be affected, betulinic acid derivatives are assumed to interact with the postbinding virus-cell fusion process.
