The present invention relates to novel pyridazinone compounds, pharmaceutical compositions comprising those compounds and to methods of using such compounds and compositions to inhibit aldose reductase, lower sorbitol levels and, thus, lower fructose levels, and/or treat or prevent diabetic complications such as diabetic neuropathy, diabetic retinopathy, diabetic nephropathy, diabetic cardiomyopathy, diabetic microangiopathy and diabetic macroangiopathy in mammals. This invention also relates to methods of affording cardioprotection to subjects not suffering from diabetes. This invention also relates to pharmaceutical compositions and kits comprising a combination of an aldose reductase inhibitor (ARI) of this invention and a sorbitol dehydrogenase inhibitor and to methods of using such compositions or kits to treat or prevent the above diabetic complications in mammals. This invention also relates to other combinations with the ARIs of this invention, including combinations with adendsine agonists; NHE-1 inhibitors; glycogen phosphorylase inhibitors; selective serotonin reuptake inhibitors; GABA agonists; antihypertensive agents; 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors; phosphodiesterase-5 inhibitors; and to glucose lowering agents.
本发明涉及新型吡啶二酮化合物,包括这些化合物的药物组合物,以及使用这些化合物和组合物来抑制醛糖还原酶,降低山梨醇水平,从而降低果糖水平,并/或治疗或预防哺乳动物中的糖尿病并发症,如糖尿病神经病变、糖尿病视网膜病变、糖尿病肾病、糖尿病心肌病、糖尿病微血管病和糖尿病大血管病。本发明还涉及一种为非糖尿病患者提供心脏保护的方法。本发明还涉及包括本发明的醛糖还原酶抑制剂(ARI)和山梨醇脱氢酶抑制剂的组合的药物组合物和套装,以及使用这些组合物或套装来治疗或预防哺乳动物中上述糖尿病并发症的方法。本发明还涉及与本发明的ARI的其他组合,包括与腺苷激动剂的组合;NHE-1 抑制剂;糖原磷酸化酶抑制剂;选择性5-羟色胺再摄取抑制剂;GABA 激动剂;降压药物;3-羟基-3-甲基戊二酰辅酶A还原酶抑制剂;磷酸二酯酶-5 抑制剂;以及降糖药物。
