– SCB-4380 (SCB 4380, SCB4380) is the first potent, selective inhibitor for PTPRZ (protein tyrosine phosphatase receptor-type Z) with IC50 of 0.4 uM against human Z-ICR-catalyzed hydrolysis.
SCB-4380 also strongly inhibits PTPRG (IC50=0.4 uM), and shows little inhibition on PTPRA, PTPRM, PTPRS, PTPRB, PTPN1 and PTPN6.
SCB-4380 inhibites PTPRZ activity in C6 glioblastoma cells, and suppresse cell migration and proliferation in vitro and tumor growth in a rat allograft model.
