Inhibition of recombinant perforin-mediated lysis of SRBC by compounds at a final concentration of 20 μM as determined by measuring cell turbidity detected by absorbance at a wavelength of 650 nM.
An IC50 was calculated from a five-point dose–response curve from compound concentrations of 100, 20, 4, 0.8, and 0.16 μM.
Inhibition of recombinant perforin-mediated lysis of nucleated (Jurkat T lymphoma) cells by compounds at a final concentration of 80 μM as determined by a 51Cr release assay in the presence of 0.1% bovine serum albumin.
Inhibition of recombinant perforin-mediated lysis of nucleated (Jurkat T lymphoma) cells by compounds at a final concentration of 1 μM as determined by a 51Cr release assay in the presence of 0.1% bovine serum albumin.
