The response of human colon cancer cells to C-1748 (4-methyl-1-nitroacridine derivative) treatment
PublikacjaPrzeprowadzone badania miały na celu określenie wpływu pochodnej 4-metylo-1-nitroakrydyny C-1748 na komórki ludzkiego raka okrężnicy HCT8 oraz HT29. Komórki obu linii, traktowane badanym związkiem, ulegały przede wszystkim apoptozie, przy czym liczba komórek apoptotycznych była znacznie większa w przypadku linii HCT8. Ponadto, proliferacja części komórek HCT8, została zahamowana w wyniku uruchomienia procesu starzenia, czego nie...

Combined anticancer therapy with imidazoacridinone analogue C‐1305 and paclitaxel in human lung and colon cancer xenografts—Modulation of tumour angiogenesis
PublikacjaThe acridanone derivative 5-dimethylaminopropylamino- 8- hydroxytriazoloacridinone (C-1305) has been described as a potent inhibitor of cancer cell growth. Its mechanism of action in in vitro conditions was attributed, among others, to its ability to bind and stabilize the microtubule network and subsequently exhibit its tumour- suppressive effects in synergy with paclitaxel (PTX). Therefore, the objective of the present study...
