The further in vitro growth inhibition of other cells (IC₅₀, µM) with Largazole and 16c–d.

	IC50 a (µM)
	Hela	Eca-109	Bel 7402	U937
largazole	0.17 ± 0.01	0.10 ± 0.00	0.17 ± 0.02	0.02 ± 0.00
16c	0.10 ± 0.01	0.09 ± 0.02	0.25 ± 0.07	0.08 ± 0.02

^a Compounds were tested in at least seven-dose IC₅₀ mode in duplicate with three-fold serial dilution.
