PTP1B-IN-3 is a selective and potent PTP1B inhibitor with anticancer activity that inhibits PTP1B and TCPTP.PTP1B-IN-3 is used in the study of diabetes.

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].

PTP1B-IN-1 (PTP1B inhibitor) is a potent inhibitor of protein tyrosine phosphatase 1B (PTP1B) (IC50 : 1.6 mM)

5-O-Coumaroylquinic acid (3-O-Coumaroylquinic acid), exhibits significant inhibition of PTP1B and a concentration-dependent inhibitory effect on α-glucosidase, thereby demonstrating anti-hyperglycemic properties. Additionally, this compound enhances glucose uptake and inhibits PTP1B in vitro, emphasizing its potential therapeutic applications in glucose regulation.

MurA-IN-1 (compound 1a), a PTPRR inhibitor, exhibits IC50 values of 0.09 μM for PTPRR, 0.23 μM for PTP1B, 0.75 μM for PTPN7, and 0.8 μM for PTPN5, respectively, targeting a family of human MAPK-specific protein tyrosine phosphatases[1].
