(A) Effect of A2-32-01 on the ability of recombinant human ClpP and ClpX to cleave the fluorogenic substrate casein-FITC. Mean ± SD.
(B) Effect of A2-32-01 on ClpP activity measured in mitochondrial lysates from OCI-AML2 and TEX cells after 2 hr based on cleavage of the fluorogenic substrate Suc-LY-AMC. Percent mean ± SD.
(C) Effect of 48 hr A2-32-01 treatment on the activity of ClpP in HL60, K562, OCI-AML2, and TEX cells based on the cleavage of the fluorogenic substrate Suc-LY-AMC. Normalized data are shown.
(D) Effect of 48 hr A2-32-01 treatment on the viability of HL60, K562, OCI-AML2, and TEX cells. Percent mean ± SD of viable cells was measured by trypan blue staining.
(E) Effect of 48 hr A2-32-01 treatment on the viability of WT and Rho (0) 143B cells. Percent of viable cells was measured by trypan blue staining.
