Metabolism of DAPD in human PBMCs and CEM cells incubated with 5 μM DAPD^a

Cell type	Intracellular concn (pmol/106 cells)
	DAPD	DXG	DXG-MP	DXG-DP	DXG-TP
PBMCs	0.54	3.93	Blb	Bl	Bl
CEM cells	0.02	2.30	0.07	0.04	0.46

^aCells were incubated for 24 h with 5 μM [5′-³H]DAPD (specific activity, 9.4 Ci/mmol). MP, monophosphate; DP, diphosphate. 

^bBl, below the limit of detection of 0.01 pmol/10⁶ cells.
