What was the focus of this study?

In the present study, we examined the antiproliferative effect of a copper II complex on HT-29 colon cancer cells. The Cu BrHAP 2 Schiff base compound demonstrated a potent antiproliferative effect in HT-29 cells, with an IC 50 value of 2.87 μg/ml after 72 h of treatment. HT-29 cells treated with Cu II complexes underwent apoptosis death, as exhibited by a progressive elevation in the proportion of the G 1 cell population.

The total volume of 200 L was made up by adding 25 L of AAPH working solution. Fluorescence intensity was measured at an excitation wavelength of 485 nm and an emission wavelength of 538 nm every 2 min for 2 h.
