Protein tyrosine phosphatase inhibitors: a patent review and update (2012-2023).

Introduction: Protein tyrosine phosphatases (PTPs), essential and evolutionarily highly conserved enzymes, govern cellular functions by modulating tyrosine phosphorylation, a pivotal post-translational modification for signal transduction. The recent strides in phosphatase drug discovery, leading to the identification of selective modulators for enzymes, restoring interest in the therapeutic targeting of protein phosphatases.

Areas Covered: The compilation of patents up to the year 2023 focuses on the efficacy of various classes of Tyrosine phosphatases and their inhibitors, detailing their chemical structure and biochemical characteristics. These findings have broad implications, as they can be applied to treating diverse conditions like cancer, diabetes, autoimmune disorders, and neurological diseases. The search for scientific articles and patent literature was conducted using well known different platforms to gather information up to 2023.

Expert Opinion: The latest improvements in protein tyrosine phosphatase (PTP) research include the discovery of new inhibitors targeting specific PTP enzymes, with a focus on developing allosteric site covalent inhibitors for enhanced efficacy and specificity. These advancements have not only opened up new possibilities for therapeutic interventions in various disease conditions but also hold the potential for innovative treatments. PTPs offer promising avenues for drug discovery efforts and innovative treatments across a spectrum of health conditions.
