A novel derivative of the anti-tumor agent N-[2-(dimethylamino)ethyl]acridine-4-carboxamide (DACA) was prepared by reduction of 9-oxoacridan-4-carboxylic acid to acridine-4-carboxylic acid with subsequent conversion to N-(4-aminobutyl)acridine-4-carboxamide (C4-DACA). Molecular modeling studies suggested that a DACA analogue comprising a side chain length of four carbons was optimal to form formaldehyde-mediated drug-DNA adducts via the minor groove. An in vitro transcription assay revealed that formaldehyde-mediated C4-DACA-DNA adducts selectively formed at CpG and CpA dinucleotide sequences, which is strikingly similar to that of formaldehyde-activated anthracenediones such as pixantrone.

Receptor-specific nuclear targeting requires trifunctional metal complexes. We have synthesized [M(L2-pept)(L1-acr)(CO)3] (pept = peptide: acr = acridine-based agent) in which the fac-[M(CO) 3]+ moicty (1st function, M = 99mTc. Re) couples an acridine-based nuclear-targeting agent (2nd function. L 1-acr) and the specific cell-receptor-binding peptide bombesin (3rd function, L2-pept). The metalmediated coupling is based on the mixed ligand [2+1] principle. The nuclear targeting agents have been derivatised with an isocyanide group for monodentate (L1) and bombesin (BBN) with a bidentate ligand (L2) for complexation to fac-[M(CO)3]+. For nuclear uptake studies, the model complexes [Re(L2)(L 1-acr)(CO)3] (L2 = pyridine-2-carhoxylic acid and pyridine2.4-dicarhoxylic acid) were synthesized and structurally characterized. We selected acridine derivatives as nucleartargeting agents, because they are very good nucleus-staining agents and exhibit strong fluorescence. Despite the bulky metal complexes attached to acridine. all [Re(L2)(L1-acr)(CO)3] showed high accumulation in the nuclei of PC3 and B16F1 cells, as evidenced by fluorescence microscopy. For radio-pharmaceutical purposes, the 99mTc analogues have been prepared and radioactivity distribution confirmed the fluorescence results. Coupling of BBN to L2 gave the receptor-selective complexes [M(L 2-BBN)(L1-acr)(CO)3]. Whereas no internalization was found with B16F1 cells, fluorescence microscopy on PC3 cells bearing the BBN receptor showed high and rapid uptake by receptor-mediated endocytosis into the cytoplasm, but not into the nucleus.

Pyrrolobenzodiazepine hybrids linked to acridone/acridine ring systems at C8-position have been designed and prepared that exhibit significant DNA-binding affinity, and a representative compound shows promising in vitro anticancer activity.

The title compound has been prepared in four steps from methyl isatin-7- carboxylate. Condensations with 1-indanone and analogs gave 11H-indeno[1,2- b]quinoline-6-carboxylic acids, and with cyclohexanones gave acridine-4- carboxylic acids.

A new synthesis of substituted acridine-4-carboxylic acids and the anticancer drug N-[2-dimethylamino)ethyl]acridine-4-carboxamide (DACA)

A new synthesis of substituted acridine-4-carboxylic acids 2 from methyl 2-[N-(2-carboxyphenyl)amino]benzoates (4) is reported, via NaBH4 reduction of the corresponding imidazolides (5), oxidation of the resulting alcohols 6 to aldehyde 7, and cyclisation of these with trifluoroacetic acid to the methyl acridine-4-carboxylates (8), followed by base hydrolysis. Direct amidation of 8a provides a new route to the clinical anticancer drug DACA (3) which avoids use of the irritant acid 2a.
