Abstract
A series of acridin-3,6-diyl dithiourea hydrochloride derivatives (alkyl-AcrDTU) was prepared and tested against sensitive and drug resistant leukemia cell lines for their cytotoxic/cytostatic activity. The products (ethyl-, n-propyl-, n-butyl-, n-pentyl-AcrDTU) showed high DNA binding affinity via intercalation ( K = 7.6 − 2.9 × 10 5 M −1). All derivatives inhibited proliferation of HL-60 cells and its resistant subline HL-60/ADR, unexpectedly the resistant subline was more sensitive than the parental one (IC 50 = 3.5 μM, 48-treatment of HL-60/ADR with pentyl-AcrDTU). Cytotoxicity of tested compounds was associated with their DNA-binding properties and the level of intracellular thiols has been changed in the presence of AcrDTU.
