title: Synthesis and anticancer activity of benzyloxybenzaldehyde derivatives against HL-60 cells.
abstract: A series of benzyloxybenzaldehyde derivatives were prepared and tested against the HL-60 cell line for anticancer activity. Preliminary structure-activity relationships were established. It was discovered that 2-(benzyloxy)benzaldehyde (17), 2-(benzyloxy)-4-methoxybenzaldehyde (26), 2-(benzyloxy)-5-methoxybenzaldehyde (27), 2-(benzyloxy)-5-chlorobenzaldehyde (28), 2-[(3-methoxybenzyl)oxy]benzaldehyde (29), 2-[(2-chlorobenzyl)oxy]benzaldehyde (30), and 2-[(4-chlorobenzyl)oxy]benzaldehyde (31) exhibited significant activity at 1-10 microM. Among them, compound 29 was the most potent one. The morphological assessment and DNA fragmentation analysis indicated that these compounds arrested cell cycle progression at G2/M phase and induced cell apoptosis. They resulted in the loss of mitochondrial membrane potential after 12h of treatment.
