approximately 50 novel β-carbolines structurally related to harmine. Harmine is known for its anticancer properties and is a DYRK1A inhibitor. Of the synthesized compounds, the most active in terms of growth inhibition of five cancer cell lines are cytostatic and approximately 100 times more potent than harmine but demonstrated no DYRK1A inhibitory activity. These novel β-carbolines display similar growth
为了克服癌细胞对凋亡刺激的内在抗性,我们设计并合成了约50种与harmine结构相关的新型β-咔啉。Harmine以其抗癌特性而闻名,是DYRK1A抑制剂。在合成的化合物中,就五种癌细胞系的生长抑制而言,最活跃的化合物具有细胞生长抑制作用,并且其功效比聚异戊二烯高约100倍,但没有DYRK1A抑制活性。这些新的β-咔啉在对凋亡刺激敏感且具有抗性的癌细胞中显示出相似的生长抑制活性。使用ChemGPS-NP,我们发现活性较高的β-咔啉比活性较低的化合物都具有更大的亲脂性和更大的亲脂性。最后,基于NCI人肿瘤细胞系抗癌药物筛选和NCI COMPARE算法,5a和5k似乎起蛋白质合成抑制剂的作用。
