UNC9036
UNC9036 is a STING PROTAC degrader with a DC50 value of 227 nM. UNC9036 binds to and activates STING, recruits the VHL E3 ligase to target phosphorylated STING for ubiquitination and proteasomal degradation. UNC9036 inhibits downstream innate immune signaling events triggered by cytoplasmic DNA sensing, including IRF3 phosphorylation. UNC9036 reduces the antiviral response of cells infected with HSV-1. UNC9036 can be used in the research of renal cell carcinoma.

UNC9036 (0-31.6 μM; 0-24 h) potently degrades STING in Caki-1 renal cell carcinoma cells with a DC50 of 227 nM and achieves 91.68% maximal degradation after 24 h, with significant degradation detectable within 8 h[1].
UNC9036 (5 μM; 24 h) degrades wild-type, cGAMP binding-deficient (R238A), and TBK1 phosphorylation-deficient (S366A) STING, but does not degrade trafficking-deficient (EDAA) or palmitoylation/activation-deficient (CACA) STING in Caki-1 renal cell carcinoma cells[1].
UNC9036 (0.316 μM; 6 h) dampens STING-mediated DNA sensing signaling in Caki-1 renal cell carcinoma cells by reducing STING protein levels and suppressing ISD90-induced and 2'3'-cGAMP-induced IRF3 phosphorylation, while having minimal effect on poly(I:C)-induced IRF3 phosphorylation[1].
UNC9036 (3 μM; 16 h) treatment significantly reduces the anti-viral response in Caki-1 renal cell carcinoma cells infected with HSV-1, as evidenced by increased viral titers compared to DMSO control[1].
