N-alkyl-substituted indazole-5-carboxamides, developed as potential drug and radioligand candidates for the treatment and diagnosis of Parkinson's disease (PD) and other neurological disorders, is reported. Recent efforts have been focused on the development of subnanomolar potent, selective MAO-B (N1-alkyl-substituted compounds 12a–14a and 15) and dual active MAO-A/B (N2-methylated compounds 12b–14b) inhibitors
据报道,对结构优化的N-烷基取代的吲唑-5-羧酰胺类进行了药理和理化分析,已开发出其作为治疗和诊断帕金森氏病(PD)和其他神经系统疾病的潜在药物和放射性配体候选物。最近的努力集中在开发具有纳摩尔浓度的亚纳摩尔有效的选择性MAO-B(N1-烷基取代的化合物12a - 14a和15)和双活性MAO-A / B(N2-甲基化的化合物12b - 14b)抑制剂,具有纳摩尔浓度。分别对MAO-B和MAO-A酶有中等活性。两个系列中最有前途的类药物衍生物是N-(3-氯-4-氟苯基)-1-甲基-1 H-吲唑-5-羧酰胺(13a,NTZ-1441,IC 50 hMAO-B 0.662 nM,相对于MAO-A选择性> 15000倍)和N -(3-氯-4-氟苯基)-2-甲基-2 H-吲唑-5-甲酰胺(13b,NTZ-1442,IC 50 hMAO-B 8.08 nM,IC 50 hMAO-A 0.56μM,SI
