DMU-212, a methoxylated resveratrol analog, has significant anticancer activity, and selectively
targets tumor cells. A library of E-diarylstilbenes structurally related to DMU-212 has been synthesized
and evaluated for anticancer activity against a large panel of 45 human cancer cell lines.
From this study, DMU-212 (3a) exhibited an average growth inhibitory effect (GI50) of 3.5 M
against all the human cancer cell lines in the panel, and was particularly effective against the four cancer
cell lines: SNB-75 (CNS), MDA-MB-435 (melanoma), A498 (renal), and MCF7 (breast), with
GI50 values of 1.88, 1.04, 0.74 and 1.66 µM, respectively. Also, the 4’-chloro analog of DMU-212, 3d,
exhibited 98 and 80 percent growth inhibition against MDA-MB-435 (melanoma) and K-562 (leukemia) cancer cell lines
at a concentration of 10 M. Further investigation of DMU-212 and its analogs may provide novel therapeutic avenues for
treatment of a variety of human cancers.
DMU-212,一种甲氧基化的白藜芦醇类似物,具有显著的抗癌活性,并选择性地靶向肿瘤细胞。已经合成了一系列结构上与DMU-212相关的E-二芳烯烃,并评估其对45种人类癌细胞系的抗癌活性。在这项研究中,DMU-212 (3a) 对所有人类癌细胞系的平均生长抑制效果(GI50)为3.5 μM,对四种癌细胞系表现出特别有效的效果:SNB-75(中枢神经系统)、MDA-MB-435(黑色素瘤)、A498(肾脏)和MCF7(乳腺),其GI50值分别为1.88、1.04、0.74和1.66 μM。此外,DMU-212的4'-氯类似物3d在10 μM浓度下对MDA-MB-435(黑色素瘤)和K-562(白血病)癌细胞系表现出98%和80%的生长抑制。对DMU-212及其类似物的进一步研究可能为治疗各种人类癌症提供新颖的治疗途径。
