PROTAC STING degrader-4
Based on 1 Customer Validation
PROTAC STING degrader-4 is a nitro-free covalent STING PROTAC degrader with a DC50 of 3.23 μM. PROTAC STING degrader-4 effectively inhibits STING as well as its downstream signaling, such as p-TBK1 and p-NF-κB (p-P65), and immune-inflammatory cytokines. PROTAC STING degrader-4 mitigates kidney and blood inflammation in Cisplatin (HY-17394)-induced acute kidney injury (AKI) mice model.
(Pink: STING ligand (HY-176183); Blue: Cereblon ligand (HY-103596); Black: linker (HY-176182)).

PROTAC STING degrader-4 (Compound 2h) (0.6-40 μM, 2-72 h) dose- and time- dependently degrades STING for 72 h, with a DC50 of 3.23 μM (24 h) in THP-1 dual cells[1].
PROTAC STING degrader-4 (10 μM, 48 h) induces the degradation of STING via the proteasome pathway[1].
PROTAC STING degrader-4 (0.3-20 μM, 16 h) dose-dependently reduced protein levels of p-TBK1 and p-NF-κB (p-P65), suppressing the STING downstream signaling cascade beyond direct degradation of STING in THP1-Dual cells[1].
PROTAC STING degrader-4 (0.6-20 μM, 2 h) significantly and dose-dependently decreases the production of IFN-β and CXCL10 and inhibits IFNB1, CXCL10 and ISG15 mRNA expression in THP1-Dual cells induced by MSA-2 (HY-136927)[1].
PROTAC STING degrader-4 (0.03-30 μM, 24-48 h) exhibits a no or weak cytotoxicity in THP1-Dual and RAW-Lucia cells (below 20 μM) and in human and mouse normal cells (below 30 μM)[1].

Result:Dose-dependently degraded STING with a DC50 of 3.23 μM (24 h) in THP-1 dual cells.
Continuously reduced the expression level of STING in THP1-dual cells for 72 h in THP-1 dual cells.
Induced potent degradation of STING, and this degradation effect was not inhibited by lysosome inhibitor BAF (Bafilomycin A1) (HY-100558) but was reversed by proteasome inhibitor MG132 (HY-13259) Induced the degradation of STING via the proteasome pathway rather than its warhead molecule or E3 ligase ligand, BAF (a lysosome inhibitor) and MG132 (a proteasome inhibitor).
