Naphthaquinone moiety is present in various cancer drugs. We have synthesized two derivatives from lawsone using phenylenediamine and 4-amino phenol by ultra sound irradiation technique. The synthesized derivatives 10,12-dihydro-5-10-diazatetraphene-12-one and 2-(4-anilino)-1,4-naphthaquinone were characterized by elemental analysis and various spectral techniques like UV-visible, IR, NMR (1H and 13C) and gas chromatographic mass spectra. The study focus to predict the anticancer activity of the synthesized compounds by in silico molecular docking studies using Schrödinger software suit. The selected protein was protein kinase CK2 (PDB ID: 1M2R). Both the derivatives have better interaction with various amino acids present in active site of the protein than the parent compound lawsone. The new derivative 2-(4-anilino)-1,4-naphthaquinone exhibit lowest glide score of -2.8 kcal/mol. From the result, structural modification of the parent compound proved to be a lead compound for further drug design investigations.
萘醌分子存在于多种抗癌药物中。我们使用苯二胺和 4-氨基苯酚,通过超声辐照技术合成了两种萘醌衍生物。合成的衍生物 10,12-二氢-5-10-重氮四烯-12-酮和 2-(4-苯胺基)-1,4-萘醌通过元素分析和各种光谱技术如紫外-可见光、红外光谱、核磁共振(1H 和 13C)和气相色谱-质谱进行了表征。研究重点是利用 Schrödinger 软件包进行分子对接研究,预测合成化合物的抗癌活性。所选蛋白质为蛋白激酶 CK2(PDB ID:1M2R)。与母体化合物 lawsone 相比,这两种衍生物都能更好地与蛋白质活性位点上的各种氨基酸相互作用。新衍生物 2-(4-苯胺基)-1,4-萘醌的滑翔得分最低,为 -2.8 kcal/mol。从结果来看,母体化合物的结构改造被证明是进一步药物设计研究的先导化合物。
