Description

PROTAC IRAK4 degrader-14 is an orally active IRAK4 PROTAC degrader with a DC50 of 2.4 nM. PROTAC IRAK4 degrader-14 inhibits proinflammatory responses in multiple cell types including T cells, monocytes and keratinocytes. PROTAC IRAK4 degrader-14 is applicable to research related to psoriasis[1]. (Pink: IRAK4 ligand (HY-19836); Blue: MDM2 ligand (HY-N0004); Black: linker).

In Vitro

PROTAC IRAK4 degrader-14 (Compound Ori-Zim-6) (250 nM; 3-24 h) induces time-dependent IRAK4 degradation in human monocytic THP-1 cells, achieving >90% degradation within 12 h and complete degradation by 24 h when treated at 250 nM[1].
PROTAC IRAK4 degrader-14 (250-500 nM; 12-24 h) induces proteasome-dependent, NCL- and MDM2-dependent ubiquitination and degradation of IRAK4, and promotes assembly of an MDM2-NCL-PROTAC-IRAK4 quaternary complex in human monocytic THP-1 cells[1].
PROTAC IRAK4 degrader-14 (0.01-1 μM; 24 h) concentration-dependently inhibits LPS-induced pro-inflammatory mediator (CCL2, CXCL8, IL-6, TNF-α) mRNA expression in human monocytic THP-1 cells[1].
PROTAC IRAK4 degrader-14 (0.01-1 μM; 24 h) concentration-dependently inhibits pro-inflammatory cytokine (TNF-α, IL-2, IFN-γ) mRNA expression in human Jurkat T cells[1].
PROTAC IRAK4 degrader-14 (0.01-1 μM; 24 h) concentration-dependently inhibits IL-1β-induced pro-inflammatory mediator (TNF-α, IL-6, CXCL8, IL-19) mRNA expression in human keratinocyte HaCaT cells[1].

Real Time qPCR[1]

Cell Line: LPS-Stimulated Human Monocytic THP-1 Cells
Concentration: 0.01, 0.1 and 1 μM
Incubation Time: 24 h
Result: Caused concentration-dependent reductions in mRNA levels of pro-inflammatory mediators CCL2, CXCL8, IL-6, and TNF-α.
Exhibited more potent inhibition of CCL2, IL-6, and TNF-α mRNA expression than the reference degrader KT-474 at equivalent concentrations.

Real Time qPCR[1]

Cell Line: Human Jurkat T Cells
Concentration: 0.01, 0.1 and 1 μM
Incubation Time: 24 h
Result: Suppressed T cell activation via reduced mRNA levels of TNF-α, IL-2, and IFN-γ.
Exhibited more potent suppression of IFN-γ mRNA than KT-474 at equivalent concentrations.

Real Time qPCR[1]

Cell Line: IL-1β-Stimulated Human Keratinocyte HaCaT Cells
Concentration: 0.01-1 μM
Incubation Time: 24 h
Result: Suppressed mRNA levels of TNF-α, IL-6, CXCL8, and IL-19.
Exhibited stronger suppression of IL-6, CXCL8, and IL-19 mRNA levels than KT-474 at equivalent concentrations.

In Vivo

PROTAC IRAK4 degrader-14 (Compound Ori-Zim-6) (20 mg/kg; p.o.; once daily for 5 consecutive days) exhibits significant efficacy in an Imiquimod (IMQ) (HY-B0180)-induced psoriasis mouse model, along with favorable safety profiles including recovery of body weight and serum liver function parameters[1].

Animal Model: BALB/c
(male, 6-8 weeks old)[1]
Dosage: 20 mg/kg
Administration: p.o.; daily; 5 consecutive days
Result: Reduced total Psoriasis Area and Severity Index (PASI) scores, ear thickening, spleen enlargement, and dorsal skin epidermal thickness.
Downregulated mRNA expression of IL-1β, IL-23, Lipocalin-2 (Lcn2), and TNF-α in ear skin tissues.
Prevented IMQ-induced body weight loss.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
