JTT 551 can be used in the research of type 2 diabetes mellitus. JTT 551 is selective a protein tyrosine phosphatase 1B (PTP1B) inhibitor, with Kis of 0.22 μM and 9.3 μM for PTP1B and TCPTP (T-cell protein tyrosine phosphatase), respectively.
PTP1B-IN-3 diammonium is a highly effective and orally bioavailable inhibitor of the protein tyrosine phosphatase 1B (PTP1B) enzyme, with an IC50 value of 120 nM for both PTP1B and TCPTP. This compound exhibits potent antidiabetic and anticancer properties, as supported by extensive research [1] [2].
