are as defined in the specification; intermediates used in their preparation, preparation processes and use thereof. The present invention produces new harmine derivatives with enhanced antitumour activity and lower nervous system toxicity by structurally modification of the parent structure of β-carboline of harmines at position 1, 2, 3, 7 and 9. The compounds of the present invention can be prepared easily with high yield. They can be used in manufacture of a variety of antitumour medicines and medicines used in treatment of tumour diseases in combination of light or radiation therapy.

Seven 3-N-substituted derivatives of 3-amino-beta-carboline were synthesized and their affinities for the benzodiazepine receptor were assessed in vitro. Two compounds, 3-(ethylamino)-beta-carboline and 3-[(methoxycarbonyl)amino]-beta-carboline (beta-CMC), showing IC50 values of 460 and 71 nM, respectively, were selected for in vivo studies. The former compound showed long-lasting proconvulsant activity in Papio papio baboons while beta-CMC was shown in mice to selectively antagonize the sedative effects of diazepam without exhibiting convulsant, proconvulsant, or anxiogenic activity by itself.
