Abstract
SA51, a medium potency inhibitor of protein tyrosine phosphatase 1B (PTP1B), was identified to be a potent
inhibitor of IκB kinase β (IKKβ). Consistent with this, SA51 prevented lipopolysaccharide (LPS)-induced
breakdown of IκBα in macrophages. The effects of SA51 in mice were compared with those of structurally
related compounds, SA18 and SA32, which were previously reported as inhibitors of both enzymes - less
potent against IKKβ but more potent against PTP1B compared to SA51. SA51 improved glucose tolerance and
lipid parameters in mice, consistent with the results reported for IKKβ+/? mice. In contrast, SA18 and SA32
showed anti-obesity effects without anti-diabetic effects. Collectively, the effects of SA51 could be due largely
to the inhibition of IKKβ, whereas SA18 and SA32 may be more likely to inhibit PTP1B, consistent with their
relative in vitro inhibitory effects.
