3BrB-PP1 is an ATP-competitive analog that exhibits specific inhibitory activity towards protein kinase. It is effective in inhibiting protein kinase with mutations in the ATP-binding pocket, specifically the mutation of Thr97 within Sty1's ATP-binding pocket.
Tautomycin is a potent and specific protein phosphatases 1 and 2A inhibitor (Kiapp of 0.16 nM and 0.4 nM for PP1 and PP2A, respectively), and is an antifungal antibiotic isolated from the bacterium Streptomyces verticillatus.
Enpp-1-IN-11 (compound 23) is a highly potent inhibitor of Ecto-nucleotide pyrophosphatase phosphodiesterases 1 (ENPP1), with a Ki value of 45 nM. It demonstrates excellent stability in human and mouse plasma and exhibits low clearance in both human and mouse liver microsomes. Enpp-1-IN-11 holds promise for anticancer research [1].
Enpp-1-IN-9, a powerful inhibitor of ectonucleotide pyrophosphatase-phosphodiesterase 1 (ENPP1), exhibits wide substrate specificity, capable of cleaving various bonds such as phosphodiester bonds of nucleotides and nucleotide sugars, as well as pyrophosphate bonds of nucleotides and nucleotide sugars. Its potential application lies in the fields of cancer and infectious disease research[1].
