STX-0119

Research use only, not for human use.

STX-0119 is a selective, orally active STAT3 dimerization inhibitor that suppresses STAT3 transcription with an IC50 of 74 μM.

STX-0119 is a selective, orally active STAT3 dimerization inhibitor. STX-0119 inhibits STAT3 transcription with an IC50 of 74 μM.

STX-0119 (10-50 μM; 24 h) inhibits STAT3 dimerization through a direct interaction with the STAT3 protein and not via the modulation of upstream regulators such as JAK in HEK293 and MDA-MB-468 cells.STX-0119 (10-50 μM; 24 h) reduces the expression of STAT3 target proteins.Western Blot Analysis Cell Line:MDA-MB-468 cells Concentration:10, 20 and 50 μM Incubation Time:24 h Result:Reduced the expression of STAT3 target proteins, namely, c-myc, cyclin D1, and survivin, in a concentration-dependent manner. Did not suppress the expression of those STAT3-regulated oncoproteins.

STX-0119 (160 mg/kg; oral gavage; daily for 4 days) inhibits SCC-3 tumor growth in mice.The plasma concentration of STX-0119 (160 mg/kg; oral gavage) is maintained at >100 μg/mL (>260 μM), even at 8 h after administration.Animal Model:Male BALB/cA-ν/ν nude mice, SCC-3 lymphoma xenograft model Dosage:160 mg/kg Administration:Oral gavage, daily for 4 days Result:Suppressed the growth of SCC-3 cells significantly on the fourth day.
