  Novel NO-releasing derivatives of betulinic acid with antitumor activity

  摘要：

  Thirteen novel NO-releasing derivatives of betulinic acid (BA) bearing two types of NO-donors (nitrates and furoxans) were synthesized and evaluated for their antitumor activity. The results showed that furoxan-based derivatives exhibited higher antitumor activity than nitrate-based derivatives, with compounds 11a and 11b displaying promising potency against B16 cell lines and HepG2 cell lines (IC50 < 1 mu mol/L). We supposed that NO-releasing amount of these derivatives which can be detected by Griess method may contribute more to their antitumor activity. As a result, furoxan-based derivatives released larger amount of NO than that of nitrate-based derivatives, which partially explained the higher anti-tumor activity of the former.

  Structural modification was performed at the C-28 position of betulonic acid (BetA). Twenty-five BetA derivatives were synthesized, and evaluated for their antitumor activities against MGC-803, PC3, Bcap-37, A375, and MCF-7 human cancer cell lines by MTT assay. Among the derivatives, most of the derivatives had significant antiproliferative ability (IC50 < 19 μM). Compound 3k, the most active compound

  在丁二酸（BetA）的C-28位置进行结构修饰。合成了二十五个BetA衍生物，并通过MTT分析评估了它们对MGC-803，PC3，Bcap-37，A375和MCF-7人癌细胞系的抗肿瘤活性。在衍生物中，大多数衍生物具有显着的抗增殖能力（IC 50  <19μM）。活性最高的化合物3k在五种癌细胞系上的IC 50值分别为3.6、5.6、4.2、7.8和5.2μM，并被选择用于随后的荧光染色和流式细胞术分析细胞凋亡。结果表明，复合3k可以诱导MGC-803细胞凋亡，在10μM处理36 h后，凋亡率达到28.33％。另外，对癌细胞凋亡信号通路的研究表明，化合物3k诱导的MGC-803细胞的凋亡可能是通过线粒体内在途径进行的。

  Seventeen new derivatives of betulinic acid (BA) with potential anti-tumor activity have been synthesized. In order to improve the bioactivity of BA, we connected BA and nitric oxide donors together via different linkers. The results of the biological activity of these derivatives showed that four compounds exhibited obvious cytotoxicity against human hepatocellular carcinoma cells in vitro.

  Betulin (BT) and its derivatives have been reported to affect several key genes of cell-cycle regulators. However, their specific targets havenit yet been discovered. As an important cell cycle regulator, Cyclindependent kinase-2 (CDK2) has become a potential target for cancer therapy. Here we describe the design, synthesis and antitumor activities in vitro of eleven new BT nitrates. The results revealed that compound (20) possesses potent antitumor activity against human breast cancer MCF-7 cell lines (IC50 < 10 IM). In order to investigate potential protein target, BT nitrates were subjected to docking studies with CDK2. Compound (20) showed a very good binding affinity for CDK2 via hydrogen bonding interactions. Thus, the CDK2 inhibitory potential could make compound (20) possible candidate as the antitumor agent.
