Biological assessment of new tetrahydroacridine derivatives with fluorobenzoic moiety in vitro on A549 and HT-29 cell lines and in vivo on animal model

AbstractA new series of tetrahydroacridine derivatives with the fluorobenzoyl moiety was synthesized and evaluated for cytotoxic activity against lung cancer cell lines A549 and colorectal cancer HT29. The cytotoxic activity of the compounds was compared on the somatic cell line —EAhy926. Compounds showed high cytotoxic activity on A549 cells (IC50 183.26–68.07 μM) and HT29 cells (IC50 68.41 –19.70 μM), higher than controls—etoposide (IC50 451.47  μM) toward A549 and 5-fluorouracil (IC50 1626.85  μM) against HT29. Derivative4 was the most cytotoxic to A549, whereas for the cell lines HT29 compound6. Selected compounds showed similar cytotoxicity to the EAhy926 cell line (IC50 about 50  μM). In the hyaluronidase inhibition assay, all compounds exhibited anti-inflammatory activity, including4 exhibiting the best inhibitory activity —IC50 of 52.27  μM when the IC50 heparin was 56.41  μM. Mathematical modeling was performed to determine LD50 after intraperitoneal, oral, intravenous and subcutaneous administration and to predict potential mutagenicity and carcinogenicity of the compounds analyzed. Obtained results showed that tested derivatives are slightly toxic compounds, and LD50 values (mg/kg) ranged from 680 to 1200 (oral rat model), the analyzed compounds have low mutagenic potential, and differences between derivatives are insignificant and very low probability of carcinogenicity. To confirm mathematical calculations, an in vivo test was carried out...
