RP 001 (hydrochloride)

RP 001 is a potent sphingosine-1-phosphate receptor 1 (S1P1) agonist (EC50 = 9 pM). It is competitive with W146 (Cay-10009109), a selective S1P1 antagonist, and induces internalization and polyubiquitination of S1P1 in a dose-dependent manner. RP 001 induces dose-dependent lymphopenia in mice (EC50 = 0.03 mg/kg). It reduces S1P1-EGFP expression ex vivo on lymphocytes in the isolated lymph node of Edg1eGFP/eGFP mice but has no effect in vivo. RP 001 also completely inhibits M. stadtmanae (MSS) rechallenge-induced enlargement of B cell-rich tertiary lymphoid tissues (TLTs) and reduces neutrophil accumulation in the airways of a mouse model of experimental hypersensitivity pneumonitis.Formal Name: N-[4-[5-[3-cyano-4-(1-methylethoxy)phenyl]-1,2,4-oxadiazol-3-yl]-2,3-dihydro-1H-inden-1-yl]-beta-alanine, monohydrochloride.
