A commercial laccase, Suberase® from Novozymes, was used to catalyse the synthesis of 5,6‐dihydroxylated benzo[b]furans and catechol derivatives. The yields were, in some cases, similar to or better than that obtained by other enzymatic, chemical or electrochemical syntheses. The synthesised derivatives were screened against renal (TK10), melanoma (UACC62), breast (MCF7) and cervical (HeLa) cancer
来自 Novozymes 的商用漆酶 Suberase® 用于催化 5,6-二羟基苯并 [b] 呋喃和儿茶酚衍生物的合成。在某些情况下,产量类似于或优于通过其他酶促、化学或电化学合成获得的产量。合成的衍生物针对肾 (TK10)、黑色素瘤 (UACC62)、乳腺癌 (MCF7) 和宫颈 (HeLa) 癌细胞系进行筛选。GI50、TGI和LC50是首次报道。抗癌筛查表明,5,6-二羟基苯并[b]呋喃的细胞抑制作用对黑色素瘤(UACC62)癌细胞系最有效,其中几种化合物表现出有效的生长抑制活性(GI50 = 0.77–9.76 µM),其中两种化合物的活性优于抗癌剂依托泊苷 (GI50 = 0.89 µM)。一种化合物对肾 (TK10) 癌细胞系表现出强效活性 (GI50 = 9.73 µM),两种化合物对乳腺癌 (MCF7) 癌细胞系表现出强效活性 (GI50 = 8.79 和 9.30 µM)。这些结果鼓励对
