资料参考

TY 52156 (1-(4-chlorophenylhydrazono)-1-(4-chlorophenylamino)-3,3-dimethyl-2-butanone) is a novel S1P3 receptor antagonist [1].

Sphingosine 1-phosphate (S1P) is a bioactive lysophospholipid mediator mainly released from activated platelets and implicated in many biological responses, such as angiogenesis, vascular development, and cardiovascular function [1].

In vitro: TY-52156 preferentially inhibited the S1P-induced increase in [Ca2+]i in S1P3-CHO cells. TY-52156 competitively inhibited the dose-dependent [Ca2+]i increase elicited by S1P in S1P3-CHO with the Ki value of ～110 nM for S1P3 receptor. TY-52156 showed submicromolar potency and a high degree of selectivity for S1P3 receptor. TY-52156 (10 μM) inhihbited 24 GPCRs and three ion channels by 〈 30%. S1P dose-dependently decreased CF (Coronary Flow) in perfused rat heart. S1P dose-dependently induced vasoconstriction in isolated canine cerebral arteries. In HCASMCs, TY-52156 inhibited S1P-induced Rho activation.

In vivo: in SD rats, oral bioavailability of TY-52156 was ～70.9%. In rats, pretreatment with TY-52156 significantly attenuated FTY-720-induced bradycardia, a broad agonist of S1P receptors. Pretreatment with TY-52156 prevented the FTY-720-P-induced increase in [Ca2+]i in a dose-dependent manner.
