The use of a quartz crystal microbalance with dissipation monitoring approach clearly supports the critical role played by B - ring hydroxyls in their interactions with a cisplatin - bound double - stranded DNA surface ; an increase in the number of hydroxyl groups on the B - ring of flavonols parallels the increase in their reaction rates with cisplatin and correlates well with their reported effects on leukemia cell apoptosis efficacy .
