RDN2150
Based on 1 publication(s) in Google Scholar
RDN2150 is a ZAP-70 inhibitor with an IC50 of 14.6 nM, and it exhibits selectivity for Syk over other kinases. RDN2150 inhibits signal transduction and activation of T cells/CAR-T cells, reduces the phosphorylation level of Erk1/2, suppresses the induction of CD69 and IL-2, and downregulates phosphotyrosine signaling pathways including hnRNP sites in T cells. RDN2150 can be used for psoriasis-related research.
The free form of the compound is prone to instability, it is advisable to consider the stable salt form (RDN2150 TFA) that retains the same biological activity.
For research use only. We do not sell to patients.

In Vitro
RDN2150 (0.1-10 μM; 3 h) blocks LAT Y220 phosphorylation, disrupts the LAT/SLP76 signalosome, and inhibits downstream Erk1/2 and PLCγ1 activation in Jurkat T cells[2].
RDN2150 (0.1-10 μM; 25 h) inhibits T cell activation markers in Jurkat T cells. In soluble antibody, APC-pMHC/TCR and CD19-CAR/Raji stimulation models, concentrations of 0.1-10 μM reduce CD69 expression and IL-2 secretion, while a concentration of 10 μM completely abrogates soluble antibody-induced CD69 expression[2].

Cell Line:Jurkat T cells (JOT1 and CD19-CAR Jurkat sublines)
-
Concentration:0.1 μM; 1 μM; 10 μM; 100 nM
-
Incubation Time:3 h
-
Result:Reduced basal Erk1/2 phosphorylation at 100 nM.
Impaired phosphorylation of LATY220 across all three stimulation methods at 10 μM.
Left phosphorylation of LckY394 unaffected at any concentration.
Significantly reduced phosphorylation of Erk1T202Y204/Erk2T185Y187 at 1 μM and 10 μM after 2.5 min of stimulation across all activation models.
Significantly enhanced PLCγ1Y783 induction after soluble antibody stimulation at low concentrations (0.1 μM, 1 μM).

Animal Model:BALB/c (female, 6-8 weeks old, 18-20 g, Imiquimod-induced psoriasis-like dermatitis)[1]
-
Dosage:2% (62.5 mg per application)
-
Administration:topical; once daily; 7 days
-
Result:Significantly reduced cumulative psoriasis severity total score (0-12 scale) compared to vehicle/ointment base controls, with statistically significant differences observed from day 2 onward.
Significantly decreased individual scores for scales, skin thickness, and erythema (0-4 scales each) with statistically significant differences from day 2 onward.
Significantly reduced splenomegaly, resulting in a lower spleen index (spleen weight/body weight) compared to the vehicle group.
