CYM50308 is a potent, selective and high affinity sphingosine-1-phosphate receptor 4 (S1P4-R) agonist with an EC50 of 56 nM. CYM50308 displays 37-fold more selective for S1P4-R than S1P5-R. CYM50308 has no activity at S1P1-R, S1P2-R and S1P3-R subtypes at concentrations up to 25 μM[1].

In Vitro	The disclosed lead molecule CYM50308 (Compound 24f) displays low nanomolar S1P4-R agonist activity and exquisite selectivity over the other S1P-Rs subtypes. Noteworthy, CYM50308 provides a valuable pharmacological tool to explore the effects of the S1P4-R signaling cascade and elucidate the molecular basis of the in vivo receptor function[1].
