Figure 5. PB1 and PB2 do not substantially scavenge superoxide in a cell-free system.

Figure 5

PB1 and PB2 exhibit very low superoxide scavenging activity in a non-dose-dependent manner. Their borane-deprotected analogs (dPB1 and dPB2), as well as TCEP and the borane-deprotecting agent DABCO, do not show significant reduction in superoxide levels at any tested concentrations. * (p<0.05); ** (p<0.01).
