TD52, an Erlotinib (HY-50896) derivative, is an orally active, potent cancerous inhibitor of protein phosphatase 2A (CIP2A) inhibitor. TD52 mediates the apoptotic effect in triple-negative breast cancer (TNBC) cells via regulating the CIP2A/PP2A/p-Akt signalling pathway. TD52 indirectly reduced CIP2A by disturbing Elk1 binding to the CIP2A promoter. TD52 has less p-EGFR inhibition and has potent anti-cancer activity^[1].

TD52 (2-10 μM; 48 hours) shows anti-proliferative ability and induces differential apoptotic effects in these cell lines^[1].
TD52 (5 μM; 48 hours) has minimal effects on p-EGFR or EGFR expression but downregulated CIP2A expression^[1].
TD52 (2.5, 5, 7.5 μM; 48 hours) time-dependently induces apoptosis accompanied with downregulating CIP2A and p-Akt^[1].
TD52 (5 μM; 24 hours) significantly increases the phosphatase activity of PP2A in TNBC cells^[1].
TD52 (5 μM; 48 hours) has no obvious effects on other common RTKs, such as IGFR, PDGFR and VEGFR2^[1].
