Novel series of 4,6-disubstituted-1,3,5-triazines containing hydrazone derivatives were synthesized employing ultrasonic irradiation and conventional heating. The ultrasonication gave the target products in higher yields and purity in shorter reaction time compared with the conventional method. IR, NMR (H 1 and C 13), elemental analysis, and LC-MS confirmed the structures of the new products. The antimicrobial and antifungal activities were evaluated for all the prepared compounds against some selected Gram-positive and Gram-negative bacterial strains. The results showed that only two compounds 7i (pyridine derivative) and 7k (4-chlorobenzaldehyde derivative) displayed biological activity against some Gram-positive and Gram-negative bacteria, while the rest of the tested compounds did not display any antifungal activity.
使用超声辐照和传统加热合成了含有酰肼衍生物的4,6-二取代-1,3,5-三嗪小说系列。与传统方法相比,超声辐照在更短的反应时间内以更高的产率和纯度给出了目标产物。红外光谱、核磁共振(H 1和C 13)、元素分析和液相色谱-质谱证实了新产品的结构。对所有制备的化合物针对一些选择的革兰氏阳性和阴性细菌菌株进行了抗菌和抗真菌活性评估。结果显示,只有两种化合物 7i(吡啶衍生物)和 7k(4-氯苯甲醛衍生物)对一些革兰氏阳性和阴性细菌显示了生物活性,而其余被测试的化合物没有显示任何抗真菌活性。
