The cytotoxicity of a series of aminonaphthoquinones resulting from the reaction of suitable aminoacids with 1,4-naphthoquinone was assayed against SF-295 (glioblastoma), MDAMB-435 (breast), HCT-8 (colon), HCT-116 (colon), HL-60 (leukemia), OVCAR-8 (ovarian), NCI-H358M (bronchoalveolar lung carcinoma) and PC3-M (prostate) cancer cells and also against PBMC (peripheral blood mononuclear cells). The results demonstrated that all the synthetic aminonaphthoquinones had relevant cytotoxic activity against all human cancer lines used in this experiment. Five of the compounds showed high cytotoxicity and selectivity against all cancer cell lines tested (IC50 = 0.49 to 3.89 µg·mL−1). The title compounds were less toxic to PBMC, since IC50 was 1.5 to eighteen times higher (IC50 = 5.51 to 17.61 µg·mL−1) than values shown by tumour cell lines. The mechanism of cell growth inhibition and structure–activity relationships remains as a target for future investigations.
对 SF-295(胶质母细胞瘤)、M

VCAR-8(卵巢癌)、NCI-H358M(支气管肺泡肺癌)和 PC3-M(前列腺癌)进行了细胞毒性试验、HCT-116(结肠癌)、HL-60(白血病)、O
VCAR-8(卵巢癌)、NCI-H358M(支气管肺泡癌)和 PC3-M(前列腺癌)癌细胞,以及 P
BMC(外周血单核细胞)。结果表明,所有合成
萘醌类化合物对实验中使用的所有人类癌细胞株都具有相关的细胞毒性活性。其中五种化合物对所有测试的癌细胞株都表现出较高的细胞毒性和选择性(IC50 = 0.49 至 3.89 µg-mL-1)。标题化合物对 P
BMC 的毒性较低,因为其 IC50 值(IC50 = 5.51 至 17.61 µg-mL-1)是肿瘤
细胞系的 1.5 至 18 倍。细胞生长抑制机制和结构-活性关系仍是未来研究的目标。
