Two series of combinatorial library of 3,6-disubstituted-7H-1,2,4-triazolo-[3,4-b]-1,3,4-thiadiazines bearing an amide linkage were synthesized. All the newly synthesized compounds were characterized by spectral analyses. The newly synthesized compounds were screened for their cytotoxicity, anti-inflammatory, and analgesic activities. Among the tested compounds, the compound (Ar = 4-(methoxybenzyl)piperazine)
合成了两个带有酰胺键的3,6-二取代-7 H -1,2,4-三唑-[3,4- b ] -1,3,4-噻二嗪组合库。所有新合成的化合物都通过光谱分析进行了表征。筛选新合成的化合物的细胞毒性,抗炎和止痛活性。在测试的化合物中,该化合物(Ar = 4-(甲氧基苄基)哌嗪)是最有前途的分子,在(MCF-7)细胞中最大抑制浓度(IC 50)值的一半为14.24μM。化合物 (Ar = 4-(氯苄基)哌嗪), , 和 (Ar = 2-(氟苯基)哌嗪)在50 mg / kg的剂量水平下表现出出色的抗炎活性,几乎与标准药物相当。如果被测化合物具有镇痛作用,则这些化合物, , 和 在100和200 mg / kg / po剂量下均显示出更有效和一致的活性,而致溃疡的风险较小。
