groove of DNA. In present study we synthesized series of novel Pyrazolo [1,5-a]pyrimidine derivatives. The newly synthesized compounds were characterized by elemental analysis, IR, 1H NMR, and mass spectral data. The selected compounds were studied for interaction with Calf thymus DNA (CT-DNA) using electronic spectra, viscosity measurement and thermal denaturation studies. Further, molecular interactions
DNA分子是大量抗癌和抗病毒药物的靶标,这些药物与DNA的主要或次要凹槽形成共价和非共价加合物。在目前的研究中,我们合成了一系列新型的吡唑并[1,5- a ]嘧啶衍生物。通过元素分析,IR,1 H NMR和质谱数据对新合成的化合物进行了表征。使用电子光谱,粘度测量和热变性研究研究了所选化合物与小牛胸腺DNA(CT-DNA)的相互作用。此外,揭示了化合物IIIa和IVa的分子相互作用通过计算方法。通过分子对接在不同的DNA模型中探索了配体与双螺旋DNA结合的优选方式以及优选的DNA沟。
