targets. Molecular Docking helped to verify the results of these compounds against the selected bacterial target d -alanyl- d -alanine carboxypeptidase (PDB ID: 1PW1). The crystal structure of ligand and docked conformers in the active site of 1PW1 were analyzed. As a result structure-activity relationships are proposed. Structures of compounds 14 and 16 were obtained through single crystals X-ray diffraction
摘要 在这项工作中,对 20 种不对称查耳酮和姜黄素类似物的抗菌特性进行了筛选。查耳酮和类姜黄素衍生物中芳香环中的给电子基团产生了更高的抗菌作用。化合物1、9和15对大肠杆菌和金黄色葡萄球菌表现出良好的活性。这些化合物针对九种具有病理学意义的微生物进行了进一步评估。Pharmmaper 用于针对重要细菌目标的化合物的目标捕捞。分子对接有助于验证这些化合物针对选定的细菌靶标 d-丙氨酰-d-丙氨酸羧肽酶(PDB ID:1PW1)的结果。分析了 1PW1 活性位点中配体和对接构象异构体的晶体结构。因此,提出了构效关系。化合物 14 和 16 的结构是通过单晶 X 射线衍射研究获得的。化合物 14 在单斜空间群 P21/c 中结晶,晶胞尺寸 a = 13.1293(3) A, b = 17.5364(4) A, c = 15.1433(3) A, β = 95.6440(10), V = 3469
