Two efficient and practical approaches are reported for the synthesis of β- and γ-carboline derivatives from 3,4-dibromopyridine as a common starting material. The β-carbolines were prepared by site-selective Pd-catalyzed C–C coupling with o-bromophenylboronic acid and subsequent cyclization by double C–N coupling with amines. γ-Carbolines were prepared from the same starting material by C–N coupling

The invention relates to chemical compounds and their use as a medicament in the treatment of a disease associated with genotoxic stress-induced I KK/NF-κΒ (NF-kappaB) activation, preferably in the treatment of a subject suffering from cancer exhibiting genotoxic stress-induced I KK/NF-κΒ activation. The invention further relates to a pharmaceutical composition comprising a compound of the invention for the treatment of a subject afflicted by a disease associated with genotoxic stress-induced I KK/NF-κΒ activation.
A series of novel 9-substituted beta-carboline derivatives was synthesized from harmine and l-tryptophan, respectively. Cytotoxic activities of these compounds in vitro were investigated. The results showed that most compounds of 9-substituted beta-carboline derivatives had more remarkable cytotoxic activities in vitro than their corresponding parent compounds.

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.
