Etidronic acid (HEDP) is a diphosphonate which affects calcium metabolism. It inhibits ectopic calcification and slows down bone resorption and bone turnover.

Sodium etidronate (Didronel) is a synthetic therapeutic diphosphonate analog of endogenous pyrophosphate. As a member of the family of drugs known as bisphosphonates, Sodium etidronate differs from endogenous pyrophosphate in its resistance to enzymatic hydrolysis. This agent adsorbs to hydroxyapatite cells and reduces the number of osteoclasts, thereby inhibiting abnormal bone resorption. Etidronate may also directly stimulate bone formation by osteoblasts.

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].

PTP inhibitor 1 is an inhibitor of cell-permeable protein tyrosine phosphatase (PTP) that covalently binds the catalytic domain of the Src homology region 2 domain-containing phosphatase (SHP-1(ΔSH2)),with Ki of128 μM.

BVT948 is a protein tyrosine phosphatase (PTP) inhibitor that also inhibits lysine methyltransferase SETD8 (KMT5A) and various cytochrome P450 (P450) isoforms.

LMPTP Inhibitor 1 Dihydrochloride is a compound selectively targeting low molecular weight protein tyrosine phosphatase (LMPTP), exhibiting potent inhibitory activity with an IC50 value of 0.8 μM for LMPTP-A.

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.

Razuprotafib (AKB-9778) is a protein tyrosine phosphatase ß (HPTPß) inhibitor with an IC50 of 50 nM. It effectively activates Tie-2 and provides protection against acute kidney injury.

Suramin Sodium Salt (BAY-205) is a sodium salt form of suramin, a polysulphonated naphthylurea with potential antineoplastic activity. Suramin blocks the binding of various growth factors, including insulin-like growth factor I (IGF-I), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and tumor growth factor-beta (TGF-beta), to their receptors, thereby inhibiting endothelial cell proliferation and migration. This agent also inhibits vascular endothelial growth factor (VEGF)- and basic fibroblast growth factor (bFGF)-induced angiogenesis; retroviral reverse transcriptase; uncoupling of G-proteins from receptors; topoisomerases; cellular folate transport; and steroidogenesis.

Cyt-PTPε Inhibitor-1 (A Inhibitor-1) is an inhibitor of cytosolic protein tyrosine phosphatase ε. Cyt-PTPε Inhibitor-1 blocks the dephosphorylation of c-Src and exhibits anti-osteoclastic activity.

Pentamidine dihydrochloride (MP-601205 dihydrochloride) is an aromatic diamidine agent effective against various microorganisms, including protozoa (Trypanosoma brucei, Leishmania spp., and Babesia spp.) and fungi (Pneumocystis jirovecii). It is a potent and selective inhibitor of protein tyrosine phosphatases and phosphatase of regenerating liver. Pentamidine dihydrochloride inhibits the parasite Leishmania infantum with an IC50 of 2.5 μM.

(Rac)-RK-682 is a racemic mixture that functions as a protein tyrosine phosphatases (PTPases) inhibitor, specifically targeting protein tyrosine phosphatase 1B (PTP-1B), low molecular weight protein tyrosine phosphatases (LMW-PTP), and cell division cycle 25B (CDC-25B), with inhibitory concentrations (IC50s) of 8.6 μM, 12.4 μM, and 0.7 μM, respectively [1].
