TYY-31
TYY-31 is an orally active, selective S1PR1 agonist with an EC50 of 1.13 pM. TYY-31 promotes the phosphorylation of ERK1/2. TYY-31 exerts anti-inflammatory and immunosuppressive effects, ameliorates DSS-induced colitis in mice, and reduces peripheral blood lymphocyte counts in mice in a dose-dependent manner. TYY-31 can be used for the research of ulcerative colitis.

S1PR1 1.13 pM (EC50) |
TYY-31 is a highly selective S1PR1 agonist in Tango CHO cells, with single-digit picomolar potency against S1PR1, exhibiting over 106-fold selectivity over S1PR2, S1PR3 and S1PR5, and over 30000-fold selectivity over S1PR4[1].
TYY-31 (treated at 10 μM for 1.5 h followed by a 20 h recovery) potently induces S1PR1 internalization in HEK293T cells stably expressing S1PR1, with an EC50 of 0.73 nM[1].
TYY-31 (1-1000 nM) activates ERK1/2 phosphorylation in a concentration-dependent manner in S1PR1-expressing cells, indicating that it activates the downstream signaling pathway of S1PR1[1].

TYY-31 (0.1-1 mg/kg; p.o.; once daily; for 7 consecutive days) effectively ameliorates DSS-induced colitis in mice even at doses as low as 0.1 mg/kg, with the ameliorative effect at the 0.3 mg/kg dose being comparable to that of Ozanimod (HY-12288)[1].
TYY-31 (5 μM; environmental exposure; medium replaced daily) potently inhibits the expression of key pro-inflammatory mediators in dextran sulfate sodium (DSS)-induced intestinal inflammation of zebrafish (Danio rerio), and exhibits better efficacy than Ozanimod at the same concentration[1].

Animal Model:ICR (male, 18−20 g)[1]
-
Dosage:0.1 mg/kg; 0.3 mg/kg; 1 mg/kg
-
Administration:p.o.; single dose
-
Result:Induced a dose-dependent reduction in peripheral blood lymphocyte counts.
Significantly reduced lymphocyte counts at 3 hours postadministration in mice treated with 0.3 mg/kg and 1 mg/kg.
Substantially recovered lymphocyte counts to near baseline levels by 24 hours postadministration across all doses.
-
Animal Model:unspecified (6 per group, DSS-induced colitis model)[1]
-
Dosage:0.1 mg/kg; 0.3 mg/kg; 1 mg/kg
-
Administration:p.o.; daily; 7 days
-
Result:Dose-dependently mitigated DSS-induced weight loss, with 0.3 mg/kg and 1 mg/kg doses showing body weight recovery comparable to Ozanimod (1 mg/kg).
Significantly reduced DAI scores from day 9 onward across all doses, with 0.1 mg/kg and 0.3 mg/kg demonstrating efficacy comparable to Ozanimod (1 mg/kg).
Promoted significant recovery of colon length across all doses, including the low 0.1 mg/kg dose.
Maintained near-intact mucosal architecture with only focal ulcerations in treated mice, in contrast to the model group's severe inflammation, crypt loss, and epithelial damage.
-
Animal Model:larvae (4 days postfertilization)[1]
-
Dosage:5 μM
-
Administration:environmental exposure; daily medium renewal
-
Result:Significantly suppressed DSS-induced upregulation of IL-1β, IL-8, MMP9, and TNF-α mRNA expression.
Exhibited more pronounced inhibitory effect on pro-inflammatory biomarkers than Ozanimod at the same 5 μM concentration.
