15–18. 2-aminothiazole derivatives 12 obtained by reaction of 3 with bromine then with thiourea. Compound 14 obtained by treatment of 11 with KSCN followed by cyclization. Some of the synthesized compounds 4, 5, 12, 14, 15 and 18 were screened for both analgesic and anti-inflammatory activities. All tested compounds showed good analgesic and anti-inflammatory activity in comparison to the reference standard
通过使5-溴邻氨基苯甲酸与异烟酰氯在乙酸酐存在下反应,合成了一系列新的6-溴-2-(4-吡啶基)-喹唑啉-4(3 H)-酮,它们进一步与p -氨基苯乙酮得到3-(4-乙酰基苯基)-6-溴-2-(吡啶-4-基)喹唑啉-4(3H)-一(3)。化合物3个用不同的醛,得到查耳酮衍生物进行了进一步反应4 - 10,这又经历了各种环化反应,得到环化的产物15 - 18。通过3的反应获得的2-氨基噻唑衍生物12先用溴再用硫脲。通过用KSCN处理11,然后环化获得化合物14。一些合成的化合物4,5,12,14,15和18进行了筛选既镇痛和抗炎活性。与参考标准消炎痛相比,所有测试的化合物均显示出良好的镇痛和抗炎活性。在所有测试的化合物中,化合物4和5表现出最高的抗炎活性,而化合物14和15表现出最高的镇痛活性。
