Hazard Information

Uses

RC-3095 is a bombesin/gastrin releasing peptide receptor (GRPR) antagonist[1]. RC-3095 exerts protective effects by reducing gastric oxidative injury in the arthritic mice[2].

Biochem/physiol Actions

RC-3095 is a potent BB2 (GRP-preferring) bombesin receptor antagonist.

in vivo

RC-3095 impairs aversive but not recognition memory in Wistar male rats^[1].
RC-3095 (0.3 mg/kg or 1 mg/kg; S.C.) shows anti-inflammatory effects in 2 experimental models of arthritis, collagen-induced arthritis (CIA) and antigen-induced arthritis (AIA)^[2].
Arthritic mice treated with RC-3095 show a significant reduction in the concentrations of IL-17, IL-1 , and TNF, and showed a diminished expression of GRPR^[2].

Animal Model:	Male Balb/c wild-type mice (weighing 18-25 gm) with AIA model; Male DBA/1J inbred mice (weighing 18-25 gm) with CIA model^[2]
Dosage:	1 mg/kg for AIA studies; 0.3 mg/kg or 1 mg/kg for CIA studies
Administration:	Injected SC twice a day for a total of 2 or 10 days for AIA studies; Administered SC twice a day for 10 days after the onset of the disease for CIA studies
Result:	Reduced neutrophil migration, mechanical hy pernociception, and proteoglycan loss in mice with AIA; Led to a significant reduction in arthritis clinical scores and the severity of disease in the CIA model.

storage

Store at -20°C
