Bioorthogonally
activated toxigenic effect in cancer cell culture:
(a) BxPC-3 and (b) Mia PaCa-2 cells. Dose–response study: 0.1%
(v/v) DMSO (untreated cell control, in gray); 0.67 mg/mL Pd0-resins (negative control, in black); gemcitabine (positive control,
in red); prodrug 5a,p (negative control, in blue); and
0.67 mg/mL of Pd0-resins + prodrug 5a,p (BOOM
activation, in green). Cell viability was measured at day 5 using
PrestoBlue reagent. Error bars: ± SD from n =
3.
