A series of pyrazolo[1,5-a]pyrimidine, triazolo[1,5-a]pyrimidine, and pyrimido[1,2-a]benzimidazole ring systems incorporating phenylsulfonyl moiety were synthesized via the reaction of 3-(N,N-dimethylamino)-1-aryl-2-(phenylsulfonyl)prop-2-en-1-one derivatives 2a,b with appropriate nitrogen nucleophiles. The analgesic and anti-inflammatory activities of the newly synthesized compound were investigated
通过3-(N,N,N)的反应合成了一系列吡唑并[1,5-a]嘧啶,三唑并[1,5-a]嘧啶和嘧啶并[1,2-a]苯并咪唑环系统,并结合了苯基磺酰基部分。 -二甲基氨基)-1-芳基-2-(苯磺酰基)丙-2-烯-1-酮衍生物2a,b具有适当的氮亲核试剂。在体内研究了新合成的化合物的镇痛和抗炎活性。与吲哚美辛作为参比药物相比,发现3-溴-2-苯基-6-(苯磺酰基)-7-(4-甲基苯基)吡唑并[1,5-a]嘧啶(5e)具有出色的镇痛活性,而在2-(4-溴苯基)-6-(苯磺酰基)-5-(4-甲基苯基)吡唑并[1,5-a]嘧啶(5d)的情况下观察到最高的抗炎作用。从结构活动关系(SAR)的角度来看,
