8-dione-5-oxime 2 were obtained as potential HIV-1 integrase inhibitors and analyzed by X-ray crystallography. Semiempirical theoretical calculations of energy preferred conformations were also carried out. The crystal structures of both compounds are stabilized via hydrogen bonds and pi-pi stacking interactions. The planarity of compound 1 is caused by intramolecular hydrogen bonds.
获得了2-[((2,5-二氯-4-硝基-苯基氨基)-甲氧基-甲基] -8-羟基喹啉1和2-甲基喹啉-5,8-二酮-5-肟2作为潜在的HIV -1整合酶抑制剂并通过X射线晶体学分析。还进行了能量优选构象的半经验理论计算。两种化合物的晶体结构均通过氢键和pi-pi堆积相互作用得以稳定。化合物1的平面性是由分子内的氢键引起的。
