  Synthesis and structure–activity relationships of harmine derivatives as potential antitumor agents

  摘要：

  Harmine, a naturally occurring beta-carboline alkaloid, showed good antitumor activities together with remarkable neurotoxic effects in animal models. In order to search for novel leading compounds endowed with better antitumor activities and less neurotoxicities, a series of harmine derivatives were designed and synthesized by modification of position-2, 7 and 9 of beta-carboline nucleus, and their cytotoxic activities against human tumor cell lines were investigated. Acute toxicities and antitumor activities of the selected compounds in mice were also evaluated. Structure activity relationships studies confirmed that (1) the 7-methoxy structural moiety was the pharmacophore responsible for the neurotoxic effects of this class of compounds; (2) the substituents in position-2 and 9 played a vital role in modulation of their antitumor activities.

  不对称二聚β-咔啉衍生物作为潜在抗肿瘤药的合成及其构效关系

  摘要：

  合成了一系列新的不对称的二聚β-咔啉，它们在吲哚氮和氨苄基氧之间具有一个4-6个亚甲基单元的间隔。通过光谱和分析研究证实了所有新型合成化合物的结构。筛选所有合成的化合物对九种癌细胞系的体外细胞毒活性。结果表明，化合物7c，7o和7s对测试的肿瘤细胞系表现出最高的细胞毒活性，IC 50值小于20μM。还评估了所选化合物在小鼠中的急性毒性和抗肿瘤功效，并且化合物7o表现出有效的抗肿瘤活性，肿瘤抑制率超过40％。伤口愈合试验显示了HT-29细胞运动性的特定损伤，这提示了化合物7o的抗转移潜力。此外，化合物7o在鸡绒膜尿囊膜（CAM）分析中具有明显的血管生成抑制作用。初步的结构-活性关系（SAR）分析表明：（1）吲哚环N 9位的3-苯基丙基取代基是最合适的产生有效细胞毒性剂的基团；（2）间隔物长度影响抗肿瘤能力，并且四个亚甲基单元是更有利的。

  series of newly asymmetric dimeric β-carbolines with a spacer of 4–6 methylene units between the indole nitrogen and the harmine oxygen were synthesized. Structures of all the novel synthesized compounds were confirmed by their spectral and analytical studies. All of the synthesized compounds were screened for their in vitro cytotoxic activity against nine cancer cell lines. The results revealed that

  In a continuing effort to develop novel beta-carbolines endowed with better pharmacological profiles, a series of beta-carboline derivatives were designed and synthesized based on the previously developed SARs. Cytotoxicities in vitro of these compounds against a panel of human tumor cell lines were also investigated. The results demonstrated that the N(2)-benzylated beta-carbolinium bromides 56-60 represented the most potent compounds with IC(50) values lower than 10 mu M. The application of 3D-QSAR to these compounds explored the structural basis for their biological activities. CoMFA (q(2) = 0.513, r(2) = 0.862) and CoMSIA (q(2) = 0.503, r(2) = 0.831) models were developed for a set of 47 beta-carbolines. The results indicated that the antitumor pharmacophore of these molecules were marked at position-1, -2, -3, -7 and -9 of beta-carboline ring.
