  5-(2-Aminoethyl)dibenzo[c,h][1,6]naphthyridin-6-ones:  Variation of N-Alkyl Substituents Modulates Sensitivity to Efflux Transporters Associated with Multidrug Resistance

  摘要：

  5H-8,9-Dimethoxy-5-(2-N,N-dimethylaminoethyl)-2,3-methylenedioxydibenzo [c, h]-[1,6]naphthyridin-6-one (ARC-111) has potent TOP1-targeting activity and pronounced antitumor activity. Several analogues of ARC-111 were synthesized with NH2, N-alkyl, N,N-dialkyl, pyrrolidinyl, piperidinyl, and piperazinyl substituents at the 2-position of the 5-ethyl group. The relative TOP1-targeting activity and cytotoxicity of these structural analogues were assessed in RPMI8402 and P388 tumor cells and their camptothecin-resistant variants CPT-K5 and P388/CPT45, respectively. Potent TOP1-targeting activity was retained within a series of mono N-alkyl analogues that included NHCH2CH3, NHCH(CH3)(2), and NHC(CH3)(3). TOP1-targeting activity was diminished by the presence of a N-benzyl moiety. In a comparison of a series of N-alkyl-N-isopropyl analogues, activity decreased in the order CH3 > CH2CH3 > CH(CH3)(2). Cytotoxicity in RPMI8402 and P388 did correlate with TOP1-targeting activity. Cytotoxic activity was also determined in KB3-1 cells and its variants KB/V-1 and KBH5.0. As KB/V-1 cells overexpress MDR1 and KBH5.0 cells overexpress BCRP, decreased cytotoxicity in these cell lines relative to the parent cell line is indicative of compounds that are substrates for these efflux transporters. In view of their diminished cytotoxicity in KB/V-1 cells, it appears that the likely demethylated metabolites of ARC-111, i.e., where NH2 or NHCH3 replaces the N(CH3)(2) at the 2-position of the 5-ethyl substituent, are substrates for MDR1. In contrast, no significant difference in cytotoxicity among these three cell lines was observed with other N-alkyl analogues, including NHC2H5, NHCH(CH3)(2), NHC(CH3)(3), N(CH3)(2), N(CH2CH3)(2), NCH3(CH(CH)(3))(2)), and either the pyrrolidinyl or the piperidinyl analogues. The 2-(piperazinyl) analogues were associated with diminished cytotoxicity in KB/V-1 cells, suggesting that the second basic amino substituent is associated with their recognition as substrates by MDR1. Comparative studies on the antitumor activity of ARC-111 and its N-demethylated derivatives (the NHCH3 and NH2 analogues) against SJ-BT45 medulloblastoma xenografts in scid mice revealed that the secondary amine metabolite is at least as active as ARC-111 in vivo, although the primary amine derivative was significantly less potent.

  designed, synthesized and evaluated as dual inhibitors of AChE and BuChE. To further explore the multifunctional properties of the new derivatives, their antioxidant activities and inhibitory effects on self-induced Aβ1–42 aggregation and HuAChE-induced Aβ1–40 aggregation were also tested. The results showed that most of these compounds could effectively inhibit AChE and BuChE. Particularly, compound 21d

  设计，合成和评价了一系列蝶形-O-乙酰氨基烷基苄胺，作为AChE和BuChE的双重抑制剂。为了进一步探索上自诱导Aβ的新衍生物，它们的抗氧化活性和抑制作用的多功能性质1 - 42聚集和胡胆碱酯酶诱导的Aβ 1 - 40聚合也进行了测试。结果表明，这些化合物大多数可以有效抑制AChE和BuChE。特别是化合物21d表现出最佳的AChE抑制活性（IC 50  = 0.06μM）和对BuChE的良好抑制作用（IC 50 = 28.04μM）。抑制动力学分析和分子模型研究均表明，这些化合物表现出混合型抑制作用，同时与AChE的CAS和PAS结合。除了抑制胆碱酯酶的活性，这些化合物还显示出不同水平的抗氧化剂活性。然而，这些新衍生物对自诱导和Hu AChE诱导的Aβ聚集的抑制活性不令人满意。考虑到生物学评估的结果，将设计进一步的修饰以增加对不同靶标的效力。这封信中显示的结果可能是进一步开发用于治疗阿尔茨海默氏病的多功能药物的新起点。
