Comparative efficacy
of Pn3a and analogues in a mouse model of
NaV1.7 mediated pain. (A) Local injection of Pn3a (WT)
and analogues (i.pl., 1 μM) reverses spontaneous pain behaviors
induced by i.pl. injection of the NaV1.7 activator OD1
in mice; n = 5–6 per group. (B) Systemic administration
of Pn3a (WT) and analogues (i.p., 1 mg/kg) reverses spontaneous pain
behaviors induced by i.pl. injection of the NaV1.7 activator
OD1 in mice; n = 5–6 per group. Data are presented
as mean ± SEM. Statistical significance was determined using
one-way ANOVA with Dunnett’s post-test; *, p < 0.05 compared to control, #, p < 0.05 compared
to native Pn3a (WT).
