  2,4,6-Substituted Quinazolines with Extraordinary Inhibitory Potency toward ABCG2

  摘要：

  Several members of the ABC transporter superfamily play a decisive role in the development of multidrug resistance (MDR) in cancer. One of these MDR associated efflux transporters is ABCG2. One way to overcome this MDR is the coadministration of potent inhibitors of ABCG2. In this study, we identified novel inhibitors containing a 2,4,6-substituted quinazoline scaffold. Introduction of a 6-nitro function led to extraordinarily potent compounds that were highly selective for ABCG2 and also able to reverse the MDR toward the chemotherapeutic drugs SN-38 and mitoxantrone. The binding of substrate Hoechst 33342 and the two potent inhibitors 31 and 41 which differ in their mechanism of inhibition was rationalized using the recently published cryo-EM structures of ABCG2. For a better understanding of the interaction between the inhibitors and ABCG2, additional investigations regarding the ATPase activity, the interaction with Hoechst 33342, and with the conformational sensitive 5D3 antibody were carried out.

  新型2,4,6-三取代喹唑啉衍生物作为潜在抗肿瘤药物的设计、合成和生物学评价

  摘要：

  在这项研究中，设计、合成了一系列新型2,4,6-三取代喹唑啉衍生物，并从生物学角度评估了它们对四种人类癌细胞系（Eca-109、A549、PC-3和MGC-803）的抗增殖活性。大多数设计的化合物对测试的四种癌细胞系表现出相当大的抗增殖活性，而化合物28g对MGC-803细胞和Eca-109细胞表现出最好的抗增殖活性，其IC 50值分别为1.95 μM和2.46 μM。进一步的机制研究表明，28g显着抑制MGC-803细胞的细胞迁移和集落形成。另外，28克还在 MGC-803 细胞中剂量依赖性地诱导细胞凋亡和细胞周期停滞在 S 期。总体而言，所有这些研究表明28g有潜力作为抗肿瘤药物开发的有价值的先导化合物。 图形概要

  In this study, a series of novel 2,4,6-trisubstituted quinazoline derivatives were designed, synthesized and biologically evaluated their antiproliferative activity against four human cancer cell lines (Eca-109, A549, PC-3 and MGC-803). The most of designed compounds showed considerable antiproliferative activity against the tested four cancer cell lines, while compound 28g displayed the best antiproliferative
