The effect of p-chlorophenylalanine [pCPA, (A)], WAY-100635 (B), or α-methylphenylalanine [AMPT, (C)] on anxiolytic-like activity of HBK-17 in the four plate test in mice. pCPA was injected intraperitoneally (i.p.) once daily for three consecutive days. Twenty-four hour after the last injection and 30 min before the test mice received (i.p.) either HBK-17 or 0.9% NaCl. WAY-100635 was administered subcutaneously 15 min before HBK-17. AMPT was injected (i.p.) 4 h before HBK-17. Vehicle-treated groups received 1% Tween (i.p.). Statistical analysis: two-way ANOVA (Bonferroni post hoc); p < 0.05, ∗∗p < 0.01 vs. respective control group receiving vehicle or 1% Tween; #p < 0.05, ##p < 0.01 vs. respective group receiving HBK-17 at the dose 5 mg/kg; n = 8 mice per group.
