Inhibition of the in vivo myotoxic activity
of
myotoxin II by different concentrations of JB006. An intramuscular
injection (50 μL) containing 50 μg (3.6 nmol; 73 μM)
of myotoxin II, previously incubated for 30 min at 37 °C with
different concentrations of JB006 (900, 100, or 20 μM) or PBS
as the negative control, was administered to groups of five mice.
After 3 h, a blood sample was collected from the tail. Plasma was
obtained following centrifugation and used to determine the activity
of CK, an enzyme released due to muscle damage. Results are presented
as mean ± SD (n = 5). Mice injected with myotoxin
II incubated with 900 μM of JB006 showed a statistically significant
difference [P < 0.01 (**)] when compared with
mice injected with myotoxin II incubated with PBS.
