Özet

In this study, BODIPY compounds (2, 3, 5 and 6) bearing 3,4-bis(3-pyridin-3-ylpropoxy)benzyl, 4-(3-pyridin-3-ylpropoxy)benzyl groups were synthesized for the first time and further functionalized in a Knoevenagel condensation reaction with 3,4-bis(3-pyridin-3-ylpropoxy)benzaldehyde and 4-(3-pyridin3-ylpropoxy)benzaldehyde. The water soluble derivatives of BODIPY compounds (3a and 6a) were synthesized by treating BODIPY compounds 3 and 6 with excess iodomethane in DMF. The photochemical properties and DNA binding modes of 3a and 6a were determined using ct-DNA by UV-Vis spectrophotometer and viscometer. DNA cleavage and topoisomerases inhibition properties were studied DNA using agarose gel electrophoresis. Their topoisomerase inhibition mechanisms were investigated at molecular level and correlations with the in vitro results were searched for using molecular docking method. In addition, cytotoxicity and phototoxicity of both compounds were performed on colorectal cancer cells (HCT-116) using MTT assay for 24 h. Annexin V-FITC/PI test was performed to determine the cell death mechanism of 6a induced by irradiation. Finally, 6a-loaded liposomes (LP6a) and PLGA nanoparticles (NP6a) were prepared and their cytotoxic and phototoxic effects were evaluated by MTT assay. The results claimed that 6a had great potential as photosensitizer agent for colorectal cancer owing to its photochemical, DNA interaction and phototoxic properties. (C) 2019 Elsevier Masson SAS.
