ptp1b-in-4

PTP1B-IN-4 (NUN-17724) is an allosteric PTP1B inhibitor with an IC50 of 8 μM. PTP1B-IN-4 can be used in studies about obesity and diabetes.

2-Bromo-4'-hydroxyacetophenone(PTP Inhibitor I) is a cell-permeable, protein tyrosine phosphatase (PTP) inhibitor that covalently blocks the catalytic domain of the Src homology region 2 domain-containing phosphatase (SHP-1(ΔSH2)) with a Ki value of 43 μM and PTP1B with a Ki value of 42 μM [1]. SHP-1 and PTP1B both have known roles in regulating insulin signaling as well as myeloid and lymphoid cell differentiation, making inhibitors of these phosphatases of interest in diabetes, cancer, allergy, and inflammation research [2].

PTP1B-IN-8 is a potent and selective inhibitor of protein tyrosine phosphatase-1B (PTP1B).

RAMB4 (PTP1B-IN-9) is a ubiquitin-proteasome system (UPS)-stressor,with anticancer activity.
