Tegeprotafib (PTPN2/1-IN-1) (Compound 124) is an orally active inhibitor targeting both PTPN2 and PTPN1B, displaying potent IC50 values at 4.4 nM for PTPN2 and 1-10 nM for PTPN1B, respectively [1].

Stevisalioside A (Compound 2), isolated from the roots of Stevia serrata, is an orally active antidiabetic agent that inhibits Protein Tyrosine Phosphatase 1B (PTP1B) with an IC50 value of 526.8 μM. It effectively lowers blood glucose levels and attenuates the postprandial peak observed in oral glucose and insulin tolerance tests in Streptozotocin-induced hyperglycemic mice [1].

Prunin (Naringenin 7-0-glucoside) possesses anti-diabetic, and anti-abacterial properties, it can inhibit protein tyrosine phosphatase 1B (PTP1B) and stimulate glucose uptake in insulin-resistant HepG2 cells; it also can stimulate growth of Pseudomonas aeruginosa and different Bacilllus sp. Prunin exhibits a markedly enhanced solubility compared to naringenin and naringin while maintaining the in vitro inhibition of HMG-CoA reductase.

MY10, a potent and orally active inhibitor of the receptor protein tyrosine phosphatase (RPTPβ/ζ), effectively reduces binge-like ethanol consumption and diminishes the rewarding effects of ethanol.

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].
