DNA-methyltransferases (DNMTs) are a class of epigenetic enzymes that catalyze the transfer of a methyl moiety from the methyl donor S-adenosyl-L-methionine onto the C5 position of cytosine in DNA. This process is dysregulated in cancers and leads to the hypermethylation and silencing of tumor suppressor genes. The development of potent and selective inhibitors of DNMTs is of utmost importance for the discovery of new therapies for the treatment of cancer. We report herein the synthesis and DNMT inhibitory activity of 29 analogues derived from NSC 319745. The effect of selected compounds on the methylation level in the MDA-MB-231 human breast cancer cell line was evaluated using a luminometric methylation assay. Molecular docking studies have been conducted to propose a binding mode for this series.
DNA甲基转移酶(DNMTs)是一类表观遗传酶,能催化将甲基供体S-腺苷-L-甲硫氨酸上的甲基基团转移到DNA中胞嘧啶的C5位置上。这一过程在癌症中发生失调,导致肿瘤抑制基因的高甲基化和沉默。开发强效且特异的DNMT抑制剂对于发现新的癌症治疗方法至关重要。本文报告了29种源自NSC 319745的类似物的合成及其DNMT抑制活性。使用发光甲基化测定法评估了选定化合物在人乳腺癌细胞系MDA-MB-231中对甲基化水平的影响。进行了分子对接研究,以提出该系列化合物的结合模式。
