Vimirogant hydrobromide
Vimirogant hydrobromide (VTP-43742 hydrobromide) is a potent, selective, and orally active RORγt inhibitor with a Ki of 3.5 nM for binding to RORγt. VTP-43742 blocks Th17 cell differentiation and reduces IL-17A production by inhibiting RORγt-mediated transcriptional activity, thereby suppressing the RORγt/Th17/IL-17 inflammatory axis. VTP-43742 can be used for research on autoimmune diseases and inflammation-related diseases.

In Vitro
Vimirogant hydrobromide (VTP-43742 hydrobromide) binds with high affinity to RORγt, with a Ki of 3.5 nM, and exhibits >1000-fold selectivity over RORα and RORβ[3].
Vimirogant hydrobromide inhibits Th17 differentiation and IL-17A secretion in mouse splenocytes with an IC50 of 57 nM, without affecting Th1, Th2, or Treg cell differentiation[3].
Vimirogant hydrobromide inhibits IL-17A secretion in activated hPBMCs with an IC50 of 18 nM[3].
Vimirogant hydrobromide inhibits IL-17A secretion in whole blood from healthy and psoriasis donors with an IC50 of 192 nM[3].

In Vivo
Vimirogant (prophylactic administration; 11 days) hydrobromide dose-dependently inhibits CD4+IL-17+IFNγ− and CD4+IL-17+IFNγ+ T cells in the spleen and draining lymph nodes of MOG35-55/CFA-immunized EAE mice; following ex vivo restimulation of splenocytes obtained from treated mice with MOG35-55, Th17-derived cytokines are specifically suppressed[4].
Vimirogant (high dose; prophylactic administration) hydrobromide completely suppresses EAE clinical scores in chronic EAE studies, with a greater degree of suppression than MM17F3; it also inhibits Th17-related markers in the spinal cord and reduces demyelination and inflammatory cell infiltration[4].
Vimirogant (30 μg/kg; p.o.; 7 days) hydrobromide reduces M1 macrophage polarization in the colonic mucosa of DSS-induced colitis mice and alleviates colitis-associated inflammatory injury; the main text states that IL-17a expression does not change under this condition[5].
Vimirogant (30 μg/kg; intragastric administration; 7 days; combined with SYD 2.50 g/kg) hydrobromide inhibits colonic mucosal inflammatory injury in DSS-induced colitis mice more strongly than SYD alone[5].

Protocols

Dual Luciferin reporter gene assay
Luciferin reporter gene assay is a reporting system to detect the activity of Firefly Luciferase using luciferin as a substrate, which is often used in the research of miRNA target gene verification and promoter transcriptive activity regulation. Dual luciferase usually refers to Firefly luciferase and Renilla luciferase.

Naïve CD4+ T-cell subset differentiation/polarization
Naïve CD4+ T-cell subset differentiation/polarization is an in vitro assay in which purified naïve CD4+ T cells are activated through TCR and CD28 costimulation and cultured with defined cytokines and neutralizing antibodies to generate Th0, Th1, Th2, Th17, or induced Treg-like populations. Differentiation is detected by subset-associated cytokines and transcription factors: IFN-γ/T-bet for Th1, IL-4/GATA3 for Th2, IL-17A/RORγt for Th17, and Foxp3 for induced Treg cells. The assay readout is usually generated by intracellular cytokine staining after restimulation, transcription-factor staining by flow cytometry, ELISA of secreted cytokines, or gene-expression analysis. The result reflects cytokine-directed lineage commitment or polarization rather than antigen-specific immune protection by itself.

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

iPSC cell differentiation
Induced pluripotent stem cells (iPSCs) are a type of cell that has similar properties to embryonic stem cells through somatic cell reprogramming.
