Zp17
Zp17 is a PROTAC degrader that targets the STING protein for degradation by recruiting cereblon, with a DC50 of 956 nM in THP-1 cells. Zp17 induces proteasome-dependent STING protein degradation and inhibits the activity of the STING signaling pathway. Zp17 alleviates renal function injury in a mouse model of acute kidney injury induced by Cisplatin (HY-17394). Zp17 exhibits STING-degrading activity in human monocytes and STING-inhibiting activity in mouse macrophage reporter cells. Zp17 can be used for research on inflammation and acute kidney injury.

Biological Activity
Zp17 (0.03-20 μM; 2-48 h) potently degrades STING in THP-1 cells via a proteasome-dependent pathway, with a DC50 of 956 nM. It achieves 95% of the maximum degradation rate within 24 h, and this degradation effect persists for at least 48 h[1].
Zp17 (0.3-20 μM; 1.5-24 h) potently inhibits STING pathway activation in RAW-Lucia cells, with an IC50 of 1.06 μM, and exhibits stronger activity than H151 and SP23[1].
Zp17 (0.3-10 μM; 2-24 h) dose-dependently inhibits MSA-2-induced STING downstream signaling pathway in THP-1 cells, and its effects on reducing pTBK1/pIRF3 levels and pro-inflammatory cytokine gene expression are stronger than those of SP23[1].
Zp17 (5-40 μM; 48 h) exhibits favorable in vitro safety, showing only extremely low cytotoxicity at concentrations up to 40 μM in THP-1, RAW264.7 and HEK293T cells[1].

-
Cell Line:THP-1
-
Concentration:Zp17 5 μM; MG132 (HY-13259) 0.06-1 μM or 1 μM; Chloroquine (HY-17589A) 10 μM
-
Incubation Time:MG132 or chloroquine pretreatment for 1 h; Zp17 treatment for 24 h
-
Result:MG132 (HY-13259) concentration-dependently attenuated Zp17-induced STING degradation, whereas Chloroquine (HY-17589A) did not significantly reverse the degradation, supporting a proteasome-dependent degradation mechanism.
