A novel class of molecules with structure N-[3-(heteroaryl)propyl]-6-methoxynaphthalene-2-carboxamides 8—13 were synthesized by condensing 6-methoxy-2-naphthoyl chloride 1 with 3-(heteroaryl)propyl amines 2—7. Compounds 8—12 were evaluated in vitro, in P388 murine lymphocytic leukemia cell line (P388) using SRB assay for cytotoxicity and in adriamycin resistant P388 murine lymphocytic leukemia cell line (P388/ADR) using MTT assay for resistant reversal activity. Compounds 8—12 were non-toxic at lower dose of 20 μg/ml, and effectively reversed adriamycin resistance. However, at higher doses (40, 80 μg/ml) they showed significant cytotxicity and hence reversal potency was not determined at these concentrations.
合成了一类新型分子,结构为 N-[3-(异芳基)丙基]-6-甲氧基萘-2-羧酰胺 8—13,通过将 6-甲氧基-2-萘酰氯 1 与 3-(异芳基)丙胺 2—7 缩合而成。化合物 8—12 在体外进行了评估,使用 SRB 法检测 P388 小鼠淋巴细胞白血病细胞系 (P388) 的细胞毒性,并使用 MTT 法检测耐阿霉素的 P388 小鼠淋巴细胞白血病细胞系 (P388/ADR) 的耐药逆转活性。化合物 8—12 在 20 μg/ml 较低剂量下无毒,并有效逆转阿霉素耐药。然而,在较高剂量 (40, 80 μg/ml) 下显示出显著的细胞毒性,因此在这些浓度下未确定逆转效能。
