JMS-053

JMS-053 is an efficient and reversible PTP4A3 inhibitor, with an IC50 value of 18 nM. JMS-053 demonstrates broad PTP4A inhibitory activity with IC50s of 50 nM and 53 nM for PTP4A1 and PTP4A2, respectively. JMS-053 exhibits IC50 values of 92.6 nM and 207.6 nM for CDC25B and DUSP3, respectively. JMS-053 can effectively inhibit the activity of PTP4A3, inhibit tumor cell proliferation and migration through multiple mechanisms such as interfering with RhoA and STAT3/p38 signaling pathway. JMS-053 can be used for the study of cancers such as ovarian cancer, breast cancer and colon cancer .
