InS3-54A18

Research use only, not for human use.

InS3-54A18 is an active analog of inS3-54 targeting the DBD of STAT3 with IC50 of 8.8 uM in STAT3-dependent luciferase reporter assay.

InS3-54A18 is an active analog of inS3-54 targeting the DBD of STAT3 with IC50 of 8.8 uM in STAT3-dependent luciferase reporter assay, with increased specificity and pharmacological properties; not only binds directly to the DBD and inhibits the DNA-binding activity of STAT3 both in vitro and in situ but also effectively inhibits the constitutive and IL-6-stimulated expression of STAT3 downstream target genes; InS3-54A18 is completely soluble in an oral formulation and effectively inhibits lung xenograft tumor growth and metastasis with little adverse effect on animals.

inS3-54A18 (5?μM) reduces wound healing to 64% and 76% for A549 and MDA-MB-231 cells, respectively. inS3-54A18 at 10?μM further reduces the healing to 47% and 39%, respectively. inS3-54A18 inhibits the expression of STAT3 downstream target genes and the binding of STAT3 to its endogenous target sequences. inS3-54A18 does not affect the constitutive or IL-6-induced STAT3 activation (Tyr705 phosphorylation) but represses STAT3 target gene (survivin) expression.

inS3-54A18 (200?mg/kg, p.o.) inhibits tumor growth, metastasis and expression of STAT3 target genes in a mouse xenograft model of A549 cells.
