21421322-8	2011	For the cancer cell viability assay the shortest mimics were found to have highest efficacy, with the best ligand having a monoethylene glycol unit (IC(50) 0.24 muM), which was slightly better than digitoxigenin (IC(50) 0.64 muM), while none of the novel cardiac glycoside mimics display an in vitro effect as high as digitoxin (IC(50) 0.02 muM).	Digitoxin	318-327	latexin	Homo sapiens	161-164
