Alternative Name: DAPH

Chemical Name: 5,6-Bis(phenylamino)-1H-isoindole-1,3(2H)-dione

Biological Activity

Selective inhibitor of the epidermal growth factor receptor (EGFR) (IC50 = 0.3 μM in vitro). Also inhibits and reverses the formation of Aβ42 fibers associated with Alzheimer's disease. Eliminates calcium influx potential when coincubated with amyloid β-peptide (1-42) (Cat.No. 1428); reduces neurotoxicity by blocking Ca2+ influx into neuronal cells.

Technical Data

Soluble to 100 mM in DMSO and to 25 mM in ethanol
>99 %
Store at RT
