YS3074
YS3074 is a selective ENPP1 inhibitor with an IC50 of 4.23 nM. YS3074 inhibits ENPP1-mediated hydrolysis of extracellular cGAMP, thereby preserving cGAMP to activate the STING signaling pathway. YS3074 exhibits antitumor effects both as a single agent and in combination with anti-PD-1 antibodies, enhancing tumor growth inhibition and prolonging survival. YS3074 can be used for research on colorectal cancer.

In Vitro
YS3074 (pre-incubation for 10 min followed by enzymatic reaction for 60 min) inhibits cellular ENPP1 activity in MDA-MB-231 cells with an IC50 of 60.4 nM[1].
YS3074 (24 h) did not show significant cytotoxicity in THP-1, THP1-Blue ISG, and THP1-Dual KO-STING cells[1].
YS3074 (1-30 μM) weakly inhibits hERG currents in CHO-K1 cells, with an IC50 >30 μM[1].

Cell Line:human THP-1-derived macrophages and murine RAW 264.7 macrophages
-
Concentration:YS3074 serial dilutions (maximum final concentration 10 μM); cGAMP 2 μM (THP-1) or 5 μM (RAW 264.7); PMA 100 nM
-
Incubation Time:12 h (initial incubation); 1 h (YS3074 preincubation); indicated time points (collection)
-
Result:Enhanced cGAMP-induced mRNA expression of IFNB1, CXCL10, and IL6 in a dose-dependent manner.
In time-course experiments, YS3074 produced stronger and longer-lasting STING target gene expression.
No obvious cytotoxicity was observed within the tested concentration range.

-
Dosage:15 mg/kg; 40 mg/kg
-
Administration:i.p.; daily; anti-PD-1 antibody i.p. every other day
