HQNO is a potent inhibitor of mitochondrial type II NADH:quinone oxidoreductase (NDH-2) in many species, including
Yarrowia lipolytica
,
S. cerevisiae
,
Gluconobacter oxydans
,
T. gondii
,
P. falciparum
, and
S. aureus
. HQNO targets the Q-site of NDH-2.
HQNO concentrations are varied from 0 to 100?μM and 0 to 300?μM for wild-type (WT) and I379E
C. thermarum
NDH-2 variant, respectively to determine IC
50
values. WT NDH-2 has an IC
50
value of 10.5±1.3?μM HQNO in the presence of 400?μM Menadione (MD). In the presence of 50?μM MD, the IC
50
value for HQNO decreases slightly to 7.3±1.2?μM and near complete inhibition (~15% residual activity) is observed with >50?μM HQNO. At 50?μM MD, HQNO inhibition is observed with an IC
50
value of 54.3±1.2?μM.
