binding constant of compound 2 with CN– was 2.3 × 105 M−1 and its ED50 for restoring the cyanide bound CcOX activity in 10 min was 16 µM. The compound interacted with CN– over the pH range 5–10. The comparison of the loss of enzymatic activity in the presence of CN– and resumption of enzymatic activity by compound 2 mediated removal of CN– indicated the efficacy of the compound as antidote of cyanide.

Next, the inhibitory activity against P. falciparum of 18 compounds were tested, founding six compounds with IC50 < 20 µM. The most active of these compounds was 8c; however, their unsaturated derivative 7c was inactive. Then, a structure-activity relationship analysis was done, founding that focused LUMO lobe on the specific molecular zone is related to inhibitory activity against P. falciparum.
