validation (pred_r2) values of 0.6969 and 0.6148 respectively. Title compounds of 1,3,4-oxadiazole derivatives were synthesized by the ring closure reactions of various acylhydrazides with carbon disulphide (4a–e) and with aromatic acids in POCl3 (5a–e). After structural elucidation, all the synthesized compounds were evaluated for their antimicrobial activity against Escherichia coli, Staphylococcus aureus
通过使用k-最近邻分子场分析(kNN-MFA)结合各种选择程序,对21个1,3,4-恶二唑分子进行了3D QSAR分析。生成了30个3D QSAR模型;根据q 2和pred_ r 2值选择这些模型之一。所选择的模型具有17个分子的训练集和测试集4个分子与验证(的q 2)和交叉验证(pred_ - [R 2)的分别0.6969和0.6148的值。 1,3,4-恶二唑衍生物的标题化合物是通过各种酰肼与二硫化碳(4a - e)和POCl 3(5a - e)中的芳香酸的闭环反应合成的。结构阐明后,评估所有合成的化合物对大肠杆菌,金黄色葡萄球菌和表皮葡萄球菌的抗菌活性。
