Biochem/physiol Actions

TCS 401 is a selective inhibitor of protein-tyrosine phosphatase 1B (PTP1B), which plays a key role in the negative regulation of the insulin signaling pathway, contributing to insulin resistance. It exhibited Ki values of 290 nM for PTP1B, with greater than 100-fold or more selectivity compared to other phosphatases. Inhibition of PTP1B by TCS 401 has been shown to sensitize the insulin signaling pathway and increase dopamine release in response to insulin. TCS-401 has also been shown to promote endothelial cell motility and to induce differentiation of retinal pigment epithelial cells toward improved contractility and motility.

Systemically released insulin crosses the blood-brain barrier and binds to insulin receptors on several neural cell types, including dopaminergic neurons. Insulin has been shown to decrease dopamine neuron firing in the ventral tegmental area (VTA), but potentiate release and reuptake

Several protein-tyrosine phosphatases (PTPs) have been proposed to act as negative regulators of insulin signaling. Recent studies have shown increased insulin sensitivity and resistance to obesity in PTP1B knockout mice, thus pointing to this enzyme as a potential drug target

Diabetes notably increases the risk for endothelial dysfunction, a main precursor for microvascular complications. While endoplasmic reticulum stress (ERS) and protein tyrosine phosphatase 1B (PTP1B) have been associated with endothelial dysfunction in resistance vessels, whether these mechanisms also contribute to
