series of N-benzoyl amino acid analogues was synthesized and obtained compounds were assessed for their ability to inhibit DNMT-dependent DNA methylation in vitro. The biological screening allowed the definition of a set of preliminary structure-activity relationships and the identification of compounds promising for further development. Among the synthesized compounds, L-glutamic acid derivatives 22, 23
抑制人类DNA甲基转移酶(DNMT)是解决不同疾病中基因表达的表观遗传异常的新方法。受到验证的虚拟筛选软件NSC137546的启发,合成了一系列N-苯甲酰基氨基酸类似物,并对获得的化合物在体外抑制DNMT依赖性DNA甲基化的能力进行了评估。通过生物学筛选,可以定义一组初步的结构-活性关系,并鉴定出有望进一步开发的化合物。在合成的化合物中,L-谷氨酸衍生物22、23和24在总细胞裂解物中显示出最高的防止DNA甲基化的能力。化合物22在微摩尔范围内以浓度依赖性方式抑制DNMT1和DNMT3A活性。此外,化合物22在人血清中证明是稳定的,因此被选作进一步生物学研究的起点。本文受版权保护。版权所有。
