A series of novel N-phenylbenzamide-4-methylamine acridine derivatives were designed and synthesized based initially on the structure of amsacrine (m-AMSA). Molecular docking suggested that the representative compound 9a had affinity for binding DNA topoisomerase (Topo) II, which was comparable with that of m-AMSA, and furthermore that 9a could have preferential interactions with Topo I. After synthesis of 9a and analogues 9b-9f, these were all tested in vitro and the synthesized compounds displayed potent antiproliferative activity against three different cancer cell lines (K562, CCRF-CEM and U937). Among them, compounds 9b, 9c and 9d exhibiting the highest activity with IC50 value ranging from 0.82 to 0.91 μM against CCRF-CEM cells. In addition, 9b and 9d also showed high antiproliferative activity against U937 cells, with IC50 values of 0.33 and 0.23 μM, respectively. The pharmacological mechanistic studies of these compounds were evaluated by Topo I/II inhibition, western blot assay and cell apoptosis detection. In summary, 9b effectively inhibited the activity of Topo I/II and induced DNA damage in CCRF-CEM cells and, moreover, significantly induced cell apoptosis in a concentration-dependent manner. These observations provide new information and guidance for the structural optimization of more novel acridine derivatives.

A new series of acridine based imidazolium salts was synthesized and evaluated for in vitro cytotoxicity against human cancer cell lines by an MTT assay. The synthesis applied a coupling of imidazoles with 9-chloroacridines, which originated from an Ullmann condensation of a 2-chloro-benzoic acid with an aniline. The target compounds were obtained in high yields. The DPPH assay indicated considerable antioxidant activity for target compounds with simple and short alkyl chains on the imidazole, while increasing chain length and the introduction of an additional π-electron system in most cases reduced the activity. All compounds exhibited low biotoxicity against non-cancerous cell lines, whereas a few compounds showed promising anticancer activity. Unlike for the reference drugs Tamoxifen and Paclitaxel, the anticancer activity of acridine imidazolium ions is specific for only selected cancer types. Reasonable fluorescent behaviour of the products provide potential for visualization of the distribution of active drugs in tissue.

PARP-1 could repair the DNA damages induced by Topo inhibitors, therefore inhibiting Topo and PARP-1 simultaneously might be able to overcome resistance and improve outcomes. In this study a series of 4-amidobenzimidazole acridines were designed and synthesized as dual Topo and PARP-1 inhibitors. Compound 11l displayed good inhibitory activities against Topo and PARP-1, as well as significantly inhibited cancer cells proliferation. Further mechanistic evaluations indicated that 11l treatment in MCF-7 cells induced accumulated DNA double-strand breaks, prompted remarkable apoptosis, and caused prominent G0/G1 cell cycle arrest. Moreover, 11l greatly suppressed tumor growth in mice, and displayed favorable metabolic properties in liver microsomes. Our study suggested that single agents inhibiting Topo and PARP concurrently might be an alternative for cancer therapy and 11l represented a potential lead compound for development of antitumor agents.
