protein-tyrosine phosphatase β

PTP Inhibitor IV is an effective protein tyrosine phosphatase (PTP) inhibitor, which can selectively inhibit DUSP14 phosphatase activity (IC50.5.21μm). PTP Inhibitor IV inhibited SHP-2, PTP1B, PTp-ε, PTP Meg-2, PTP-σ, PTP-β and PTP-μ, IC50 were 1.8 μM, 2.5 μM, 8.4 μM, 13 μM, 20 μM, 6.4 μM, and 6.7 μM, respectively. PTP Inhibitor IV affects cellular signaling by inhibiting PTP activity and may regulate specific pathways associated with PTP-mediated signaling events.

MY33-3 is a powerful and specific inhibitor of receptor protein tyrosine phosphatase (RPTP)β/ζ, demonstrating an IC50 value of approximately 0.1 μM. Moreover, MY33-3 exhibits inhibitory activity against PTP-1B with an IC50 value of about 0.7 μM. Additionally, MY33-3 has been shown to effectively decrease ethanol consumption and alleviate neuroinflammation and cognitive dysfunction induced by Sevoflurane.

bpV(phen) is a potent protein tyrosine phosphatase (PTP) and PTEN inhibitor (IC50s: 343 nM, 920 nM, and 38 nM for PTP-β, PTP-1B, and PTEN).

Rubrofusarin 6-O-β-D-glucopyranoside, a glycosidic derivative of Rubrofusarin, functions as an inhibitor of protein tyrosine phosphatase 1B (PTP1B) with an IC50 value of 87.36 μM, and is utilized in research investigating comorbid diabetes and depression [1].

Aloe-emodin-8-O-β-D-glucopyranoside (Aloe-emodin-8-O-beta-D-glucopyranoside) exhibits moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.

bpV(bipy) hydrate acts as an inhibitor for phosphoinositide 3-phosphatase (PTEN) and protein tyrosine phosphatases PTP-β and PTP-1B, with IC50 values of 18, 60.3, and 164 nM, respectively.
