(±)-Boehmenan shows potent protein-tyrosine phosphatase 1B (PTP1B) inhibitory activity in vitro with the IC(50) values of 43.5 uM, it inhibits PTP1B activity in a competitive manner. Boehmenan exhibits the potent cytotoxic effects against many cancer cell
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].
