A Facile Synthesis of 1-Trifluoromethyl-β-carboline
The two-step synthesis of the title compound has been achieved by Mannich-type condensation of tryptamine with trifluoroacetaldehyde, followed by dehydrogenation with selenium dioxide; the overall yield was 79.3percent.
β-Carbolines as specific inhibitors of cyclin-dependent kinases
Harmine (3), 7-fluoro-1-methyl β-carboline (35) and 1-(5-methyl-imidazol-4-yl) β-carboline (41) were potent and specific inhibitors of cyclin-dependent kinases. The degree of aromaticity of the tricyclic ring and the positioning of substituents are important for inhibitory activity. While most β-carbolines inhibited CDK2 and CDK5 to the same extent, selective inhibition against CDK2 was observed in 1-(2-chlorophenyl)- (12), 1-(2-fluorophenyl)- (15), and 1-(2-chloro-5-nitrophenyl)- (28) β-carbolines.
