PTPN2 and diabetes mellitus: The nine isolated newly induced compounds (S3–S6, S8, S10–S11 and S17–S18) were also evaluated for DPPH-scavenging activity, cytotoxic activity and inhibitory activity against several anti-diabetes-related targets (α-glycosidase and protein tyrosine phosphatases, including PTP1B, TCPTP, SHP1, SHP2 and CD45), and some of these newly induced compounds showed interesting activities.
