5,15-diphenylporphyrin (5,15-DPP) is a selective STAT3-SH2 antagonist [1].
Stat3 is constitutively activated in many human cancers. Stat3 functions as a critical mediator of oncogenic signaling through transcriptional activation of genes encoding apoptosis inhibitors, cell-cycle regulators and inducers of angiogenesis [2]. Aberrant STAT3 activity has been associated with transforming mechanisms induced by oncogenic tyrosine kinases [1].
In vitro: 5,15-DPP directly bound to STAT3 and antagonized the function of STAT3-SH2. 5,15-DPP selectively antagonized STAT3-SH2 with an IC50 of 0.28 μM over the other SH2-containing proteins STAT1 and Grb2[1]. The estimated KD values for the 5,15-DPP binding to STAT3 was 880 nM. Treatment with 5,15-DPP suppressed the DNA binding activity of STAT3 in a concentration-dependent manner. 5,15-DPP poorly inhibited STAT1 with an IC50 of 10 μM and showed no effect Grb2 [1].
