  specific isopeptidase to catalyze deSUMOylation modification. Inhibiting SENP1 upregulates cancer cell radiosensitivity and it becomes a promising target for radiosensitization. Herein, based on the structure of ursolic acid (UA), a total of 53 pentacyclic triterpene derivatives were designed and synthesized as SENP1 inhibitors. Ten derivatives exhibited better SENP1 inhibitory activities than UA and the

  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。
• Ursolic acid derivatives induce cell cycle arrest and apoptosis in NTUB1 cells associated with reactive oxygen species

  Twenty-three ursolic acid (1) derivatives 2-24 including nine new 1 derivatives 5, 7-11, 20-22 were synthesized and evaluated for cytotoxicities against NTUB1 cells (human bladder cancer cell line). Compounds 5 and 17 with an isopropyl ester moiety at C-17-COOH and a succinyl moiety at C-3-OH showed potent inhibitory effect on growth of NTUB1 cells. Compounds 23 and 24 with seco-structures prepared from 1 also showed the increase of the cytotoxicity against NTUB1 cells. Exposure of NTUB1 to 5 (40 mu M) and 23 (20 and 50 mu M) for 24 h significantly increased the production of reactive oxygen species (ROS) while exposure of NTUB1 to 5 (20 and 40 mu M) and 23 (20 and 50 mu M) for 48 h also significantly increased the production of ROS while exposure of cells to 17 did not increase the amount of ROS. Flow cytometric analysis exhibited that treatment of NTUB1 with 5 or 17 or 23 led to the cell cycle arrest accompanied by an increase in apoptotic cell death after 24 or 48 h. These data suggest that the presentation of G1 phase arrest and apoptosis in 5- and 23-treated NTUB1 for 24 h mediated through increased amount of ROS in cells exposed with 5 and 23, respectively, while the presence of G2/M arrest before accumulation of cells in sub-G1 phase in 5-treated cells for 48 h also due to increased amount of ROS in cells exposed with 5. The inhibition of tubulin polymerization and cell cycle arrest at G2/M following by apoptosis presented in the cell cycle of 23 also mediates through the increase amount of ROS induced by treating NTUB1 with 23 for 48 h.
