Herein, we report the synthesis and cytotoxic effects of novel chlorinated plastoquinone analogs (ABQ1-17) against different leukemic cells. Compounds ABQ3, ABQ11, and ABQ12 demonstrated a pronounced antiproliferative effect against chronic myelogenous leukemia (CML) K562 cell line with IC50 values of 0.82 ± 0.07, 0.28 ± 0.03, and 0.98 ± 0.22 μM, respectively. Among them, ABQ11 showed approximately three times higher selectivity than imatinib on CML. ABQ11-treated CML cells induced significant apoptosis at low concentration. Inhibitory effect of ABQ11 against eight different tyrosine kinases, including ABL1, was investigated. ABQ11 inhibited ABL1 with IC50 value of 13.12 ± 1.71 μM, indicating that the moderate inhibition of ABL1 kinase is just an in-part mechanism of its outstanding cellular activity. Molecular docking of ABQ11 into ABL1 kinase ATP-binding pocket revealed the formation of some key interactions. Furthermore, DNA cleavage assay showed that ABQ11 strongly disintegrated DNA at 1 μM concentration in the presence of iron (II) complex system, assuming that the major mechanism for the anticancer effects of ABQ11 is DNA cleavage. In silico ADMET prediction revealed that ABQ11 is a drug-like small molecule with a favorable safety profile. Taken together, ABQ11 is a potential antiproliferative hit compound that exhibits unique cytotoxic activity distinct from imatinib.

一系列新颖的氯化塑料醌醌类似物:抗癌活性的设计,合成和评估。

在此,我们报告了新型氯化质体醌类似物(ABQ1-17)对不同白血病细胞的合成和细胞毒性作用。化合物ABQ3,ABQ11和ABQ12对慢性骨髓性白血病(CML)K562细胞系表现出明显的抗增殖作用,IC50值分别为0.82±0.07、0.28±0.03和0.98±0.22μM。其中,ABQ11对CML的选择性比伊马替尼高约三倍。ABQ11处理的CML细胞在低浓度下诱导明显的凋亡。研究了ABQ11对八种不同的酪氨酸激酶(包括ABL1)的抑制作用。ABQ11抑制ABL1,IC50值为13.12±1.71μM,表明对ABL1激酶的中等抑制只是其出色细胞活性的部分机制。ABQ11分子对接到ABL1激酶ATP结合口袋中揭示了一些关键相互作用的形成。此外,DNA裂解分析表明,在存在铁(II)复杂体系的情况下,ABQ11会以1μM的浓度强烈分解DNA,假定ABQ11的抗癌作用的主要机制是DNA裂解。在计算机上ADMET的预测显示ABQ11是一种药物样小分子,具有良好的安全性。综上所述,ABQ11是一种潜在的抗增殖命中化合物,具有不同于伊马替尼的独特细胞毒性活性。假设ABQ11的抗癌作用的主要机制是DNA裂解。在计算机上ADMET的预测显示ABQ11是一种药物样小分子,具有良好的安全性。综上所述,ABQ11是一种潜在的抗增殖命中化合物,具有不同于伊马替尼的独特细胞毒性活性。假设ABQ11的抗癌作用的主要机制是DNA裂解。在计算机上ADMET的预测显示ABQ11是一种药物样小分子,具有良好的安全性。综上所述,ABQ11是一种潜在的抗增殖命中化合物,具有不同于伊马替尼的独特细胞毒性活性。
