五(2A-E)benzenesulfonylurea衍生物轴承哒嗪酮是通过回流适当6-芳基-2-(对- sulfamylphenyl)合成-4,5-二氢哒嗪-3(2H) -酮与benzylisocyanate在无水ķ无水丙酮2 CO 3。这些化合物通过元素分析和各种光谱技术表征。IR,1 H NMR,13 C NMR和MS数据。这些化合物(2a–e)的剂量为20 mg / kg,已在葡萄糖喂养的高血糖正常大鼠中测试了其降低血糖的活性。与标准药物格列齐特相比,化合物2b显示出更强的抗高血糖活性。化合物2b还测试了禁食正常大鼠的降血糖作用。它还显示出明显的降血糖作用(但低于格列齐特)。
Synthesis and biological evaluation of some novel sulfamoylphenyl-pyridazinone as anti-inflammatory agents (Part-II)
摘要:
Seven novel 6-aryl-2-(p-sulfamoylphenyl)-4,5-dihydropyridazin-3(2H)-ones (2a-g) were synthesized by the condensation of appropriate aroylpropionic acid and 4-hydrazinobenzenesulfonamide hydrochloride in ethanol. Structure of all compounds have been elucidated by elemental analysis, IR, H-1 NMR, C-13 NMR, DEPT and MS spectrscopy. These compounds were tested for their anti-inflammatory activity in carrageenan-induced rat paw edema model. Compound 2b exhibited anti-inflammatory activity comparable to that of celecoxib (at 5 h). Two other compounds 2d and 2g showed promising anti-inflammatory activity (edema reduction more than 80% at 5 h). These compounds (2b, 2d and 2g) did not produce any ulceration in gastric region.
