在最近的研究中,我们显示了几种吲哚5,6-二碳腈衍生物是人单胺氧化酶(MAO)A和B的有效抑制剂。为扩展这些结果并进一步确定MAO抑制的构效关系(SAR)通过该化学类别,本研究研究了另外的吲哚-5,6-二碳腈和相关的吲哚-5,6-二羧酸和吡咯并[3,4- f ]吲哚-5,7-二酮衍生物的MAO抑制特性。在活性化合物中,两种吡咯并[3,4- f ]吲哚-5,7-二酮衍生物具有IC 50抑制MAO-A(4g)和MAO-B(4d)值分别为0.250和0.581μM。但是,一般而言,吲哚-5,6-二碳腈显示出更高的MAO抑制能力,而吲哚-5,6-二羧酸则是较弱的MAO抑制剂。活性MAO抑制剂(例如4g和4d)可以用作开发治疗帕金森氏病和抑郁症等疾病的药物的先导。也正在研究MAO抑制剂作为治疗前列腺癌,某些类型的心肌病和阿尔茨海默氏病的潜在药物。

A general approach to the synthesis of new 3-acetyl-substituted pyrrolo[3,4-f]indole-5,7-diones, 3-[3-(dimethylamino)acryloyl]-1-methoxypyrrolo[3,4-f]indole-5,7-diones and similar indole-5,6-dicarbonitriles has been developed. Dimethylaminoacryloyl derivatives synthesized on their basis regioselectively reacted with hydrazine hydrochlorides and hydroxylamine with the formation of the corresponding

General methods to access new 3-formyl-substituted 1-methoxypyrrolo[3,4-f]indole-5,7-diones were developed. The synthesized 3-formylindoles react with heterocyclic aceto-phenones under acid-catalyzed conditions to give different chalcones.

Chlorination of 1-hydroxyindole-5,6-dicarbonitriles and 1-hydroxypyrrolo[3,4-f]indole-5,7(1H,6H)-diones with N-chlorosuccinimide afforded previously unknown 3,3-dichloro-3Hindole 1-oxides instead of the expected 3-chloro-1-hydroxyindoles. The latter, however, were prepared in good yields by treatment of the above 3,3-dichloro-3H-indole 1-oxides with piperidine in ethanol. Reduction of 3,3-dichloro-5
