Anti-cancer compounds and manufacturing methods thereof are disclosed. The anti-cancer compounds are 1,8-diamidoanthraquinone derivatives with amino compounds. The manufacturing method includes the steps of: add 1,8-bis(chloroacetamido)anthraquinone or 1,8-bis(3-chloropropionamido)-anthraquinone with amino compounds, catalysts, and dehydrated dimethylformamide (DMF) to form a mixture and react with one another. Then by purification and recrystallization, the anti-cancer compounds are obtained. The anti-cancer compounds of the present invention are compounds with whole new structure that overcome serious cardiac toxicity of the conventional anti-cancer drug-doxorubincin.

the synthesis of novel 6,7-dihydrodibenzo[b,j][1,7]phenanthrolinederivatives is described. In this two-step procedure, aldol addition and reductive cyclization methods are effectively utilized for the construction of C–C and C–N bonds. This highly efficient process proceeds under mild conditions, tolerates different functional groups, and provides various substituted 6,7-dihydrodibenzo[b,j][1,7]phenanthroline
By starting from a common substrate, 2-aminobenzaldehyde, both acridines and acridones were prepared. The former were generated in high yields by copper-catalyzed N-arylation followed by acid-mediated cyclization while the latter were obtained by double copper-catalyzed N-arylation followed by cyclization under the same reaction conditions. Moreover, acridine was subjected to deprotometalation by recourse
