Acridine-4-carboxamides form a class of known DNA mono-intercalating agents that exhibit cytotoxic activity against tumour cell lines due to their ability to inhibit topoisomerases. Previous studies of bis-acridine derivatives have yielded equivocal results regarding the minimum length of linker necessary between the two acridine chromophores to allow bis-intercalation of duplex DNA. We report ...
Some derivatives ot' 9-aminoacridine (1) were synthesized, and their frameshift mutagenicity and DNA binding aMnity were studied. The introduction of a methyl group into the acridine ring of 1 reduced the mutagenic activity and the intercalative DNA binding aMnity, whjle {he introdu ¢ tion of chlorine increased them. Halogenated derivatSyes f 1 showed higher toxicity against Saintonella mphiinu...

An efficient one-pot, three-component method for the preparation of indeno[1,2-b]quinoline-9,11(6H,10H)-dione, acridine-1,8(2H,5H)-dione and various multi-substituted quinoline-3-carbonitrile derivatives has been developed through the Michael addition to enaminones, which was achieved by both microwave irradiation and conventional heating.
An efficient green approach for the synthesis of 9-heteroaryl-acridine-1,8-dione derivatives (3a-f) was accomplished via reactions dimedone (1) with various heteroaromatic aldehydes (2a-f) and ammonium acetate through one-pot multicomponent in water under mild conditions using ultrasound irradiation excellent yields. Of synthesized compounds, 3d-f were novel this process presents advantages hig...
Fluorescent naphthoxazoles and their boron derivatives have been synthesized and applied as superior and selective probes for endocytic pathway tracking in live cancer cells. The best fluorophores were compared with the commercially available acridine orange (co-staining experiments), showing far better selectivity.
