Inhibition experiments were also conducted employing Aβ42, as presented in Figure . The As described in Figure , the cells in the presence of both Group A and Group B without photoactivation exhibited greater survival of over ca. 80% at up to 25 μM. The parent moiety 9,10-AQ displayed over 70% cell viability. Intriguingly, the toxicity of all molecules pre-illuminated for 1 h before 24 h incubation was lowered by up to ca. 14% at 25 μM. This suggests that the AQ series does not yield more toxic products upon photoactivation.
