Background:

Antisauvagine-30 TFA (aSvg-30 TFA) is a potent, highly selective and competitive CRF2 receptor peptidic antagonist. Antisauvagine-30 TFA exhibits a Kd of 1.4 nM and 150 nM for mCRFR2β and CRFR1, respectively[1][2][3][4].

Antisauvagine-30 (aSvg-30) prevents stress-enhanced fear conditioning and Mek-1/2-dependent activation of Erk-1/2 and p90Rsk-1. Antisauvagine-30 (aSvg-30) did not affect the phosphorylation of the PKA regulatory subunit II of stressed mice[1][2].

Antisauvagine-30 (aSvg-30; i.h. 400 ng/0.5 μl per mouse) selectively prevents the stress-induced enhancement of fear conditioning without affecting the fear conditioning of nonstressed mice[2].Antisauvagine-30 (aSvg-30) injected i.c.v. elicits a significant anxiogenic effect[3]. Animal Model: Nine-week-old male BALB/c mice[2].
