In the present study, a new series of -Aminophosphonates bearing 6-amino-1,3-dimethyluracil was synthesized in good to excellent yields (78-95%) by one-pot, three-component reaction of 6-amino-1,3-dimethyluracil, aromatic aldehydes and diethylphosphite Kabachnik-Fields reaction by using an eco-friendly Eaton's reagent. All the compounds were screened for antioxidant studies by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide (HO) methods. Among the synthesized bioactive molecules, , , , and exhibited promising antioxidant activity compared with the standard drug Ascorbic acid. Furthermore, in order to support the biological results of the compounds, molecular docking studies were performed against Aromatase enzyme for four compounds which revealed that the compounds , , , and have significant binding modes, with docking scores of -8.6, -8.4, -8.1 and -8.1 respectively and the compound specifically has equal dock score of -8.0 when compared with the standard drug Exemestane.
在本研究中,通过使用环保的伊顿试剂,使6-氨基-1,3-二甲基尿嘧啶、芳香醛和亚磷酸二乙酯进行一锅三组分反应(卡巴契尼克-菲尔德反应),以良好至优异的产率(78 - 95%)合成了一系列新的含6-氨基-1,3-二甲基尿嘧啶的α-氨基膦酸酯。采用2,2-二苯基-1-苦基肼基(DPPH)法和过氧化氢(H₂O₂)法对所有化合物进行抗氧化研究筛选。在合成的生物活性分子中,与标准药物抗坏血酸相比,[具体化合物名称未给出]表现出有前景的抗氧化活性。此外,为了支持这些化合物的生物学结果,针对四种化合物对芳香化酶进行了分子对接研究,结果表明化合物[具体化合物名称未给出]具有显著的结合模式,对接分数分别为-8.6、-8.4、-8.1和-8.1,并且与标准药物依西美坦相比,化合物[具体化合物名称未给出]的对接分数特别为-8.0。
