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.

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.
