Bis(maltolato)oxovanadium(IV)

Bis(maltolato)oxovanadium(IV) (BMOV) is a potent, reversible, competitive and orally active pan-PTP (protein tyrosine phosphatases) inhibitor. Bis(maltolato)oxovanadium(IV) inhibits HCPTPA, PTP1B, HPTPβ and SHP2 with IC₅₀s of 126 nM, 109 nM, 26 nM and 201 nM, respectively. Bis(maltolato)oxovanadium(IV) is a potent insulin sensitizer^[1][2]. IC50 & Target:IC50: 126 nM (HCPTPA), 109 nM (PTP1B), 26 nM (HPTPβ) and 201 nM (SHP2)^[2] In Vitro: Bis(maltolato)oxovanadium(IV) treatment enhances the phosphorylation of the insulin receptor and of the insulin signalling key intermediate Akt. Bis(maltolato)oxovanadium(IV) (BMOV; 50 μM) treatment also resultes in an increased glucose uptake in C2C12 cells^[1]. In Vivo: Bis(maltolato)oxovanadium(IV) (BMOV; 0.75-3.0 mmol; intraperitoneal injection; twice weekly; for 6 weeks; C57BL/6J mice) treatment ameliorates the metabolic phenotype. Liver, skeletal muscle, and adipose tissue revealed a significantly reduced PTP activity in all analysed tissues compared to HFD mice^[1].
