Table 1.

IC50 inhibition data of CQ and acetylenic compounds against P. falciparum strains according to the growth inhibition assay.

Compounds Growth Inhibition Assay P. falciparum IC50 (nM)
3D7 Dd2 IPC 4912 RF12
DAQ SYBR green I 43 ± 5 51 ± 2 49 ± 3 NT
LDH 53 ± 9 68 ± 1 NT 79 ± 10
DAQM SYBR green I 34 ± 4 61 ± 8 NT NT
LDH 23 ± 2 91 ± 9 NT 86 ± 11
CQ SYBR green I 15 ± 2 2313 ± 475 139 ± 5 NT
LDH 21 ± 1 211 ± 16 NT 205 ± 6

NT: Not tested. The SYBR green I growth inhibition assay was performed in triplicates for DAQ, DAQM and CQ. The LDH growth inhibition assay for DAQ and DAQM was performed in duplicates. CQ was tested 8 times against the 3D7 strain using the LDH assay, and in duplicates against the Dd2 and RF12 strains. Individual IC50 values are reported in Table S1.
