RLX-33

Research use only, not for human use.

RLX-33 is a potent and selective antagonist of relaxin family peptide 3 (RXFP3) that crosses the blood-brain barrier and also blocks relaxin 3-induced ERK1/2 phosphorylation.

RLX-33 is a potent, selective and blood-brain barrier (BBB) penetrant relaxin family peptide 3 (RXFP3) antagonist, also blocks relaxin-3-induced ERK1/2 phosphorylation, with IC50 values of 2.36 μM for RXFP3, 7.82 and 13.86 μM for ERK1 and ERK2 phosphorylation, respectively. RLX-33 can block the stimulation of food intake induced by the RXFP3-selective agonist R3/I5 in rats. RLX-33 can be used for the research of metabolic syndrome.

RLX-33 (10 mg/kg; IP, single dosage) attenuates the RXFP3-selective agonist R3/I5-induced increase in feeding in male Wistar rats.RLX-33 (10 mg/kg; IP, single dosage) exhibits a good brain penetration and highly protein-bound in rats plasma. Pharmacokinetic Parameters of RLX-33 in male Wistar rats (IP, 10 mg/kg).Animal Model:Male Wistar rats (intracerebroventricular administration of R3/I5 stimulated food intake Dosage:10 mg/kg Administration:IP, single dosage Result:Attenuated the R3/I5-induced increase in food intake.Animal Model:Male Wistar rats Dosage:10 mg/kg Administration:IP, single dosage (Pharmacokinetic Analysis)Result:Exhibited a good brain penetration and highly protein-bound, with protein binding of 99.8% in rat plasma.
