Effect of human procathepsin D on proliferation of human cell lines.

abstract：:FOY-305 is a synthetic serine protease inhibitor and ONO-3403 and FO-349 are its derivatives. The effects of these compounds on the proliferation of 13 human neuroblastoma cell lines were investigated in vitro by MTT colorimetric assay. The half maximum inhibition concentrations of ONO-3403 varied between 22 and 90 mi...
