“…Thus, in addition to orthosteric inhibitors, emerging evidence points to allostery as a mechanism of STAT3 inhibition observed in a number of smallmolecule inhibitors. For example, hydrogen-deuterium exchange experiments and other studies show that STAT3 inhibitors-SF-1-066, BP-1-102, and MM206may, in addition to binding to the SH2 domain, affect Targeting JAK/STAT3 Signaling the function of the SH2 domain by binding to and perturbing the structure of domains of STAT3 at a distance from the SH2 domain, suggesting an allosteric destabilizing effect on the SH2 domain (Resetca et al, 2014;Minus et al, 2015). These findings suggest the possible utility of developing allosteric inhibitors of STAT3.…”
