quinazolonoformazans were synthesized and evaluated for anti-inflammatory activity. The degree of protection provided by seven of these compounds, at a dose of 100 mg/kg, po, against carrageenin-induced edema in rat paw ranged from 26 to 57%. The four active substituted quinazolonoformazans (1, 2, 6, 8), on further evaluation for antiwrithmogenic activity, provided 10-80% protection against the aconitine-induced
合成了八种取代的喹唑酮甲甲醛并评估了其抗炎活性。这些化合物中的七个以100 mg / kg的剂量口服提供的抗角叉菜胶诱发的大鼠足水肿的保护度为26%至57%。在进一步评估抗致蠕动活性方面,四种活性取代的喹唑啉基甲酰胺(1、2、6、8)提供了10-80%的保护,以抵抗乌头碱引起的小鼠扭体反应。还确定了两种活性最高的化合物的致溃疡性。在50%的治疗大鼠中产生溃疡的剂量(UD50)分别为2和8,分别为155和260 mg / kg ip。这些取代的喹唑酮甲甲醛具有的低毒性在小鼠中的LD50值为600至1300 mg / kg,ip。
