metabolites of 1-(2-ethoxyethyl)-2-(hexahydro-4-methyl-1H-1,4-diazepin-1-yl)-1H-b enzimidazole difumarate (KG-2413), which has a potent H1-antihistaminic activity, were predicted on the basis of metabolic studies of related compounds and were synthesized to aid in identification of the actual metabolites and for examination of their antihistaminic activity. Among the twelve compounds prepared, nine
1-(2-乙氧基乙基)-2-(六氢-4-甲基-1H-1,4-二氮杂-1-基)-1H-b富马酸二苯并咪唑(KG-2413)的代谢物在相关化合物的代谢研究的基础上预测了抗组胺活性,并合成了抗组胺活性以帮助鉴定实际的代谢产物并检查其抗组胺活性。在制备的十二种化合物中,实际上发现有九种化合物是大鼠尿液中KG-2413的代谢产物。发现这些代谢物的抗组胺活性低于KG-2413。
